The invention relates to the production of uglechaninov and Tortuguero drugs, flocculants, coagulants, ameliorants, soil conditioners, fertilizers, and gumina-mineral substances with surface-active, ion exchange, chelat forming, complexing and bioactive properties.

The invention will find application in engineering (industrial) environment for detoxification and purification of soil and land polluted with organic and inorganic pollutants, for ricultu is for the treatment of sewage and disposal of rainfall, in agriculture for cleaning animal waste, as well as to restore properties and increase soil fertility.

Known composite gumina-silicon sorbent consisting of a mineral matrix and chemically associated with this matrix of humic acids (patent RF №2108859, MKI B 01 J 20/20, 20/24, 1995).

The disadvantages of this sorbent is its low efficiency and limited the possibility of its use - only for binding heavy metal ions. Due mnogostadiinost processes sorbent, which includes operations of extraction, neutralization, filtration, washing, drying and calcination, the sorbent has a high cost and its application to solve practical problems is impossible.

Also known humic concentrate containing artificially (technically) hydrated humic acids, salts of humic acids and mineral components, chemically associated with humic acids (patent RF №2125039, MKI 07 With 63/33, publ. 20.01.99, BI No. 2).

The disadvantages of the known humic concentrate are in low concentration of the active substance (no more than 15%), due to the electrolysis method of its production, little or lita and complexity of regulation of the process of electrolysis. Humic concentrate in the form of a gel (moisture content not less than 85%) has a high stickiness and extremely inconvenient when working with him. In addition, some concentrate has a relatively high cost due to the complexity and intensity of the processes of its production, including crushing and grinding of raw materials - Hamitov and natural coal range, the extraction, separation of solid and liquid phases and the electrolysis of alkaline solution that determines the limited practical application.

The known method of producing humic substances, including simultaneous crushing and mixing of coal with an alkaline solution and separation of the extract after heating (patent RF №2130004, MKI C 05 F 11/02, publ. 10.05.99, BI No. 13).

The disadvantages of this method are the large amount of waste, as the target product is a water aspirator, and the processed coal is a waste of production; limited application of the obtained water extract only as a biologically active drug in agriculture; high consumption of alkali or ash from burning coal or wood. Moreover, in the latter case, the composition of the ash is rarely controlled, and this negatively influences the composition and properties of p is ergence grinding coal, contains humic acid in a mixture of hydroxides of alkali metals, the original mix is pre-dried to a moisture content of 6-12 wt.% (patent RF №2104988, MKI C 05 F 11/02, publ. 20.02.98, BI No. 5).

The disadvantages of this method are the high energy consumption and low efficiency, due to the necessity of pre-drying the mixture of coal and hydroxides of alkali metals to the final moisture content of 6-12%; and the need for ultrafine grinding the mixture. In the process of drying coal occurs dehydration contained in humic acids and their derivatives with coagulation and transition to the inactive state.

For the subsequent alkaline hydrolysis of these substances when mechanochemical activation requires a large expenditure of alkaline reagents, in particular hydroxides of alkali metals that make up 20-35% by weight of coal. Get the target product contains a lot of alkali and has a high pH, thereby limiting its use only as a carrier or source of humates ammonium and/or alkali metal humates, the volume of applications and the demand for which is extremely small and limited to the area controllers (biostimulants) growth and development of plants.

Contamination levels of soil inorganic (heavy metals) and organic (hydrocarbon oil and petroleum products, polychlorinated polycyclic compounds) ecotoxicants reach in some cases dangerous quantities, and therefore becomes a very urgent task of rehabilitation of detoxification of contaminated soils and territories.

Known method of vermiculture soil and clean soil from oil and oil products (patent RF №2119735, MCI And 01 In 79/02, publ. 10.10.98, BI No. 28), including the introduction of contaminated soil vermicompost.

The known method has a high cost of preparation of vermicompost and not very effective for detoxification and treatment of soils contaminated by petroleum products, and heavy metals.

There is also known a method result the matter in the form of water-soluble humic acids (patent RF №2031095, MCI C 05 F 11/02, publ. 20.03.95, BI No. 8).

The disadvantages of this method are the low efficiency of the detoxification of contaminated soils, caused by the rapid leaching of soil water-soluble humic acids, their decomposition under the influence of physico-chemical (low and high values of pH of the contaminated soils and other) and microbiological factors. Due to the high cost of water-soluble humic acids and the difficulty of obtaining this method has not found practical application.

In the practice of industrial plants produce large amounts of waste which under the placement and storage in dumps, landfills, landfills, dumps, and so on, represent a dangerous source of pollution of the environment member and formed during storage of toxic elements and compounds.

Known method of land reclamation, including laying in piles of potentially fertile species of loess, clay and sand, followed by the application quasirandom layer.with. The USSR №1605958, MKI A 01 F B 79/02, 1988).

The known method is characterized by high labour costs and output and do not provide effective detoxification of otvajivali dumps of rocks and tailings, including the introduction and mixing of waste neutralizing substances such as lime, and applying a layer of soil (Beresnevich, P. C., Kuzmenko SC, Nejentsev N. G. “Environmental protection in the operation of the tailings”, M.: Nedra, 1993, S. 102-107).

The disadvantages of this method are as big neutralizing substances, high complexity and low efficiency.

One of the most dangerous sources of pollution are sewage, industrial, agricultural and other industries.

A known method of purification of waste water from inorganic, organic and microbiological contaminants, including introduction to water bactericidal and other reagents, settling and removal of sediment (Molchanov, I. P., Roxiller I. D., Zhuk E., “Purification and disinfection of wastewater of small settlements”, L: stroiizdat, 1993, S. 113, 121, 124).

As reagents used mineral coagulants (aluminium sulphate, ferric chloride, and so on), organic flocculants (polyacrylamide and derivatives based on it), as well as various combinations of coagulants and flocculants.

The disadvantages of this method include the relatively high stand is coming to live, the dependence of the efficiency of the treatment on the composition and concentration of contaminants, temperature, etc.

There is also known a method of wastewater treatment, including the introduction into the water of the reagent in the form of humic concentrate, water precipitation and removal of sediment (RF patent No. 2125039, MKI 07 With 63/33, publ. 20.01.99, BI No. 2).

The disadvantages of the method are the difficulty of obtaining and high cost of humic concentrate, so this method has not found practical application.

Environment significantly polluted well as precipitation of waste water, including precipitation of urban wastewater (WWS). WWS contain large amounts of organic matter, nutrients (nitrogen, phosphorus) and are good fertilizers. At the same time start to contain a large number of ions of heavy metals, petroleum hydrocarbons and petroleum products, and polychlorinated polycyclic organic compounds, etc.

The task of detoxification and environmentally safe disposal of salt is very important for many decades.

A known method of disposal of sewage sludge, including their mixing with peat and mineral components and the introduction of pojaluytsa is what is contained in FARS heavy metal ions are not bound, and migrate into the environment, polluting groundwater and poisoning crop production. The use of lighting is possible in limited quantities and periodically - once every few years - provided ongoing environmental monitoring and sanitary-epidemiological control.

There is also known a method of disposal of sewage sludge, comprising the introduction into them of humic drug (patent RF №2125039, MKI 07 With 63/33, publ. 20.01.99, BI No. 2).

The main disadvantage of this method is that due to the complexity of obtaining and high cost of humic concentrate he does not find practical application.

The basis for the claimed of the invention is to create a new target product of such a structure and such structure and method of preparation of such materials in such conditions and modes that would be produced in an industrial scale without significant energy and time costs for a small consumption of alkali, gumina-mineral reagent, with sorption, ion exchange, complexing, chelat forming and bioactive properties of p is inogo series namely peat, burgr, oxidized brown and oxidized coals in a synergistic unity of natural hydrated and hydrolyzed humic acids, hydrated and hydrolyzed gumina-mineral complexes and mineral components in the creation of conditions for further expanding and strengthening the positive properties at the same time avoiding the presence of the target product at hazardous concentrations of toxic organic and inorganic toxicants for the purpose of effective use for the cleaning of contaminated soil, detoxification of wastes from mining and processing of mineral resources and reclamation of dumps of rocks and tailings, sewage treatment and recycling of precipitation.

The problem is solved in that created a new gumina-mineral reagent from natural komitov and natural number of coal containing humic acids and salts of humic acids, natural hydrated humic acids, hydrolyzed humic acids, hydrated and hydrolyzed gumina-mineral and mineral complexes source komitov and natural coal of a number of chemically bonded with natural hydrated humic acids.

prasouda, chelat forming, flocculation, coagulating and biological activity.

According to the claimed invention gumina-mineral reagent is a product derived from natural komitov and natural coal series, which include:

natural hydrated humic acid, wt.% more 25,0;

mineral components, wt.% less than 30.0;

volatile matter, wt.% less 40,0;

total and soluble forms of heavy metals and benzo(a)pyrene, the contents of which are below maximum permissible concentrations established for soils.

The main content of these components is determined by the initial composition used peat, lignite, brown oxidized or stone oxidized coal, natural content-hydrated humic acids which must be not less than 25%, the ash content should not exceed 30%, and the yield of volatile substances is not more than 40%. The content controlled in the present gross and mobile forms of heavy metals and benzo(a)pyrene should not exceed specified for soils of the values of maximum permissible concentrations (MPC), as the main purpose of gumino-mineral reagent VC CLASS="ptx2">

In accordance with the claimed invention, gumina-mineral reagent can be obtained by hydration of komitov and natural coal range by mixing them with water and alkaline hydrolysis named komitov and natural, the content of which is from about 40 to about 50% by dry matter content of alkali from about 1 to about 7.5% of dry matter and water - the rest, hydration and hydrolysis is carried out to achieve the target product status from a plastic to plastic consistency and achieve pH values from 6.5 to 8.

High efficiency, gumina-mineral reagent as sorption, ion exchange, complexing, chelat forming, flocculation, coagulating and biologically active material is related to the fact that it is the molecules of humic acids are natural hydrated state, when part of their acid groups dissociative, and gidrolizovannogo state when they become water-soluble compounds. This hydrated and hydrolyzed gumina-mineral and mineral complexes with high specific surface energy and surface-active properties, synergistically enhances the effects of Danzel activity gumina-mineral reagent, defines, in turn, economically useful properties. According to him this is reflected in the form of a set of natural-hydrated humic acids, hydrated and hydrolyzed gumina-mineral and mineral components at pH values in the safe for biological objects within when the ratio of the solid and liquid phases.

Hydrated humic acids humic concentrate presents a low-molecular fragments of humic acid source komitov and coal natural number, because in the process of extraction with an alkaline reagent, humic acids pass into the water-soluble salts and then by electrolysis results in the release of humic acids from a solution of their salts.

In the molecular-mass distribution of these humic acids participate molecules with molecular weight of 27000 Dalton (67% of the total molecules).

Natural hydrated humic acids, gumina-mineral reagent presents natural high molecular weight compounds with a molecular weight of 150,000 daltons to several million daltons. Part of their functional groups is dissociated state and the That is, the reactivity of these acids increases with time, what is important for their practical use.

Unlike hydrated humic acid concentrate natural hydrated acids have lower mobility and lower solubility (that is positive to achieve the objectives of the invention in the cleaning of contaminated soils and detoxification of waste, as sharply reduced the leaching of humic acid precipitation, groundwater, and so on)

Natural hydrated humic acids have a greater affinity for soil microflora than hydrated humic acids, and have a positive effect on the growth, activity and stability of soil microflora.

Natural hydrated humic acids are less susceptible to various changes under the influence of physico-chemical factors, such as solar (ultraviolet) radiation, wetting and drying, and exposure to alkaline and acid agents, microbiological destruction.

Hydrolyzed humic acids, gumina-mineral reagent represented by fragments of natural hydrated humic acids with a molecular weight of from 1,500 to 150,000 daltons. Under alkaline hydrolysis conditions is x acids and partially the formation of humates, i.e. salts of humic acids.

Hydrated and hydrolyzed gumina-mineral and mineral complexes of gumino-mineral reagent presents activated complex heterogeneous systems, including molecular, supramolecular, cluster, associative, colloidal, aggregate, macroaggregate patterns with synergetic effect of the manifestation of the properties of humic and mineral parts of gumino-mineral reagent.

Unlike mineral components of humic concentrate hydrated and hydrolyzed gumina-mineral and mineral complexes of gumino-mineral reagent possess high adsorption and absorption activity, the ability to complexation, ion exchange and helatoobrazovatel that enhances the positive effects of gumino-mineral reagent during its use.

Contained in humic concentrate hydrated humic acids, salts of humic acids and mineral components have weak physical-chemical bond with each other. Contained in gumina-mineral reagent natural hydrated humic acids, hydrolyzed humic acid is a strong physico-chemical, chemical and mechanical connection with each other that determines qualitatively different properties and functions gumina-mineral reagent, positive influence on the solution of the problem of the claimed invention.

The problem is solved also by the fact that in the method of obtaining gumina-mineral reagent, including crushing and grinding komitov and natural coal range and mixing with the alkali, according to the invention crushing and grinding komitov and natural coal series lead when they are close to the natural humidity in which humic acids are natural hydrated state, mix hot water with sumitani and natural and hydratious during intensive physical-chemical impacts to the formation of a homogeneous mixture, then add the lye and hydrolyzing the mixture to obtain a target product from a plastic to plastic consistency and attainment of pH values from 6.5 to 8.

It is peat, lignite, brown oxidized and stone oxidized coals contain a large amount of humic acids and are characterized by low calorific value and high moisture content (20-45%). High humidity caused deliciosa capillaries, pores, micro - and macro-cracking of the peat and coals.

When high natural moisture content of the peat and coals become sticky and when the crushing and grinding of traditional methods is sticking bunkers, chutes, clogging crushing and grinding devices. For this reason, for example, the coal is dried to a moisture content of 11-13%, after which he crushed and milled. However, when the drying of the coal is removed not only loosely coupled and adsorbed water and water filling the capillaries, pores and cracks, but dehydration of humic acids, gumina-mineral complexes. This results in coagulation of humic acids with the formation of insoluble substances and their partial decomposition together with gumina-mineral complexes. Such substances completely lose their activity and other positive properties and their subsequent activation is only possible when the hydrolysis of large amounts of alkali for a long time under intensive mechanical action, at elevated or high temperatures (above 200°C) and high pressure.

Drying of coal, reducing the amount of the freely associated water and reduce its stickiness, the use of unconventional methods of greaterchina provides efficient crushing and grinding of raw materials, having, as a rule, low strength and are mainly dispersed by weight. In this crushing and grinding loosely bound water under the influence of capillary forces, surface tension forces and physico-chemical adsorption actively interact with humic acids, gumina-mineral components, increasing the degree of their natural hydration, which increases the number of dissociated acidic functional groups of humic acids, which is characteristic of many biological molecules.

Peat, natural moisture which may exceed 45-50%, pre-dried to a moisture content of about 35% and crushed.

Chopped humity and natural carbon number should be included under vigorous stirring in water heated to 95°C. the Mass of water for hydration komitov and natural is determined by the formula:

where my- weight source humite or kaustobiolit with natural humidity;

W0- natural humidity of the humite or kaustobiolit (W=0,2-0,45);

(0.5 to 0.6) is an empirical coefficient.

It is also useful in gidratirovannuyu the mixture was added sodium or potassium alkali in amount from CLASS="ptx2">

In addition, gumina-mineral reagent from a plastic to plastic consistency it is advisable to add when mixing the nitrogen-containing substance selected from the series consisting of ammonium nitrate, urea, ammonium sulfate, nitrophoska, the number of nitrogen-containing substances is up to 5% by weight of humite or kaustobiolit on the dry substance.

Chopped humite or kaustobiolit mixed with hot water, and it is expedient to introduce him to enter into the water, not Vice versa. The gradual introduction of coal into the water during intensive physical-mechanical treatment (mixing, vibro-acoustic processing, and so on) leads to the uniform distribution of water by the volume of coal. The introduction of water in the coal leads to the binding part of the coal with water and the formation of lumps of various sizes, which greatly complicates the processing of coal and homogenization of the mixture.

During intensive physical-chemical processing of coal with hot water causes additional hydration contained in natural-hydrated humic acids. In the processing is the maximum disclosure of its main components under the influence of disjoining water action arising from hydration of the se is Ino-water mixture.

During intensive physical-chemical treatment of peat is its additional dispersion.

Then according to the invention in the resulting homogeneous mixture add the lye with continued intensive physical and mechanical impact. The alkali becomes intense chemical reaction with all components of the coal, but above all with humic and gumina-mineral components.

Part of the natural hydrated humic acids interacts with the alkali with the formation of humates, i.e. salts of humic acids. When using caustic soda is sodium HUMATE, when using potassium alkali is potassium HUMATE, and when using ammonium hydroxide - ammonium HUMATE. All these humates are soluble in water and possess significant biological activity.

Lye is also actively interacts with gumina-mineral and mineral (clay) components of coal. During interaction with gumina-mineral complexes is their partial destruction with the formation of humic and mineral fractions. Humic fractions intensively hydratious and hydrolyzed with the formation of humates. Mineral fractions as clay componentise properties, thereby increasing their sorption, ion exchange and coagulating action.

The presence of the original natural hydrated humic acids, and optionally hydrated humic acids, gumina-mineral complexes and mineral (clay) particles leads to the fact that the consumption of alkali hydrolysis of humic acids, gumina-mineral complexes and mineral (clay) component becomes small. For practical cases, the desired depth of response is provided with the high consumption of alkali, in which the pH of the obtained product is 6.5-8.

This interaction generated gumina-mineral agent acquires a characteristic from visco-plastic to plastic consistency, easy then is loaded, transported and used.

The problem is solved also by way of remediation of contaminated soils, including the introduction in soil humic substances, which according to the invention as humic substances use gumina-mineral reagent containing humic acid and salts of humic acids, natural hydrated humic acids, hydrolyzed humic acids, hydrated and Hydra is mikeski associated with natural hydrated humic acids, and obtained by hydration of komitov and natural coal range by mixing them with water and alkali hydrolysis. At the same time, gumina-mineral reagent applied to the soil in an amount of from about 0.1 to about 5% by weight of the soil and mix with soil to a depth of root layer by plowing or disking or ripping.

The problem is solved in the way of detoxifying wastes from extraction and processing of mineral resources and reclamation of dumps of rocks and tailings, including the introduction and mixing of waste neutralizing substances according to the invention as a neutralizing substance use gumina-mineral reagent containing humic acid and salts of humic acids, natural hydrated humic acids, hydrolyzed humic acids, hydrated and hydrolyzed gumina-mineral and mineral complexes source komitov and natural coal of a number of chemically bonded with natural hydrated humic acids, and obtained by hydration of komitov and natural coal range by mixing them with water and alkali hydrolysis. At the same time, gumina-mineral reagent bring in waste from the wastewater, includes introduction to water humic substances according to the invention as humic substances use gumina-mineral reagent containing humic acid and salts of humic acids, natural hydrated humic acids, hydrolyzed humic acids, hydrated and hydrolyzed gumina-mineral and mineral complexes source komitov and natural coal of a number of chemically bonded with natural hydrated humic acids, and obtained by hydration of komitov and natural coal range by mixing them with water and alkali hydrolysis. At the same time, gumina-mineral reagent is injected into the waste water in an amount of from about 1 to about 7% by weight of water. After the introduction into the water of gumino-mineral reagent it is expedient to introduce the lime in amount from about 0.3% to 1.5% by weight of water.

The problem is solved also by the fact that in the method of disposal of sewage sludge, including the introduction and mixing with them humic preparation according to the invention as humic drug use gumina-mineral reagent containing humic acid and salts of humic acids, natural hydrated humic acids, hydrolisate of komitov and coal natural number, chemically related to natural hydrated humic acids, and obtained by hydration of komitov and natural coal range by mixing them with water and alkali hydrolysis, when sewage sludge is used as rekultiviruemye or insulating substrates. Gumina-mineral reagent contribute in sewage sludge in an amount of from about 0.1 to about 10% by weight of precipitation.

Further, the invention is examined with specific examples of its implementation.

Example 1

The feedstock for gumina-mineral reagent selected from a group of brown, brown oxidized and stone oxidized coals cuts “Borodino”, “Berezovsky”, “Nazarovo” Kansk-Achinsk coal basin (Krasnoyarsk region), section “Mikusinski (Orenburg oblast), Kartavtseva field (Bashkortostan), deposits of “Maritsa-East” (Bulgaria), Kuznetsk coal basin, as well as peat Shaturskaya field (Moscow region). Criteria for the selection of the raw materials included the following experimentally determined features:

1) the total contents of heavy metals and the content of mobile forms of heavy metals, which ustanovlenii metals does not exceed the corresponding values of MPC, this is guaranteed to lower the content obtained from this raw material, gumina-mineral reagent and thereby eliminates possible contamination of soil and land in the application of the target product for detoxification, purification and remediation of contaminated, broken and degreasing soil and land;

2) the release of volatile substances, having in mind that the lower the yield, the lower energy density have the coals and the higher their value as raw material for gumina-mineral reagent. In addition, the smaller the content of volatile substances, the less content in coal, bitumen and tar and the higher the efficiency of gumino-mineral reagent for the cleaning of contaminated soil, detoxification of wastes, etc.

3) the maximum content of natural-hydrated humic acids, determined by the output of “free” humic acids according to GOST 9517-76 (extraction with 1% sodium hydroxide solution), with characteristic brown and especially for brown oxidized and stone oxidized coals high natural humidity that in terms of natural occurrence of coal determines a good hydration of humic acids and their high potential interaction with the alkaline reagent;InEU and organic components of coal: the ash content is higher the stronger these relationships, and the lower the ash content, the lower the bond strength. The lower the ash content and less than strong ties, the more effective is the hydration and hydrolysis of humic acids, gumina-mineral complexes, i.e., the better the properties and functions of received gumina-mineral reagent.

The typical composition of the samples brown oxidized coal Borodinsky is presented below:

The content of natural hydrated

humic acids 75,9%

Ash 21,4%

Humidity 21.8 percent

The content of volatile substances 28,6%

Total contents of heavy metals:

Lead 0.006 mg/kg

Arsenic 0.0003 mg/kg

The content of mobile forms of heavy metals:

Manganese 0.01 mg/kg

The content of benzo(a)pyrene Traces

Source coal natural humidity, the bulk of which is represented friable earth-mass and a small part of separate pieces, passed through a hammer mill. As a result of crushing the sizes of coal does not exceed 3-5 mm After crushing, the coal is subjected to grinding in a rotary shredder brand ID-300 to a particle size less than 0.1 mm, the pH Value at which the situation heated up to 95°C water during intense vibro-acoustic effects and hydrolysis by adding caustic soda.

It is established that when the coal humidity of 50-60% is formed almost homogeneous plastic mixture of water and coal. With the introduction of alkali under vigorous stirring a homogeneous plastic mixture turns into a paste with a characteristic black glitter.

It was also established that required for hydration of mass minwater can be found from empirical formula:

where my- weight of the original coal with natural humidity;

W0- natural moisture content of the coal (W=0,2-0,45);

(0.5 to 0.6) is an empirical coefficient.

For example, for the hydration of a sample of coal, weighing 10 kg from the original (natural) humidity W0= 21,8% is required from 5.6 to 9.5 liters heated to 95°C water. If the amount of water is less than 5.6 l, then there is no good mixing of coal with water, and if the volume of water is greater than 9.5 litres, the mixture becomes easy flowing. In the range of volumes of water from 5.6 to 9.5 l humidity received gumina-mineral reagent ranges from 50 to 60%, and the content of dry matter, respectively from 50 to 40%.

When the alkali content of 0.8% not observed the formation of a characteristic homogeneous plastic paste, and when the content of alkali 2% pH of the mineral reagent pasty consistency, 1.4% of dry matter by weight of the original coal (S. C.). The pH value when it is 7.4, and store the resulting product is a decrease in the pH to 6.6 to 6.8.

The rest of Microquantities

The content of mobile forms of heavy metals:

Manganese 0.02 mg/kg

The rest of Microquantities

The content of benzo(a)pyrene is 0.0001 mg/kg

The original coal dried in a natural way on the site to a moisture content of about 21%, are crushed in a hammer mill to particle sizes less than 3 mm and pulverized in a rotary shredder brand ID-300 to particle sizes less than 0.1 mm, pH Value of aqueous extract is 5.5.

From the mass of crushed coal take samples and make their hydration heated to 95°C water during intensive mechanical impact.

Neobuichnui humidity W0=21% is required from 58 to 97.5 liters heated to 95°C water. Water is poured into the reactor, in which intense mechanical and acoustic vibration impacts submit a sample of coal. Found that when the moisture content W0less than 50% mixture contains numerous lumps that indicates the incompleteness of the processes of hydration and the presence of raw coal. When humidity W0more than 60% mixture of water and coal becomes easy flowing, indicating the excess water. It was also established that when the humidity of the reactant 50-60%, a homogeneous plastic mixture of water and coal. With the introduction of potassium alkali under vigorous stirring a homogeneous plastic mixture turns into a paste with a characteristic black glitter. The amount of alkali is 2.1% of dry matter by weight of the original coal (S. C.). The pH is about 8. After the introduction of alkali and stabilize the pH at about 8 in the resulting mass of injected nitrogen-containing substance, such as ammonium nitrate, urea, ammonium sulfate, nitrophoska, up to 3-5% by weight of coal (S. C.). It was found that after the introduction of nitrogen, the resulting paste during storage thickens, while pH decreases with Okotie) Kuznetsk coal basin is presented below:

The content of natural hydrated

humic acids 79.3 percent

The ash content of 8.6%

Humidity 42%

The content of volatile substances 31%

Total contents of heavy metals:

Lead is 0.005 mg/kg

The content of benzo(a)pyrene Traces

The original coal is dispersed granular mass of black. The coal is dried in a natural way on the site to a moisture content of approximately 38%, and then passed through a rotary shredder brand ID-300. Processing of coal in a rotary shredder is more of a “control” function and ensures the presence of particles of not more than 0.1 mm, pH Value of aqueous extract is about 5.

From the mass of crushed coal take samples and make their hydration heated to 95°C water and hydrolysis with alkali.

So, for the hydration of coal samples weighing 100 kg each, with an initial moisture content W0approximately 38% is required from 24 to 55 litres of water. Water is poured into the mixer and with vigorous stirring there poured a sample of coal. Ostanovlennyi, least 50%, for example 45%, the mixture contains unreacted rounded lumps of coal, and at a humidity of over 60%, for example 70%, the mixture becomes easy flowing. With the introduction of sodium or potassium alkali under vigorous stirring a homogeneous plastic mixture turns into a paste with a characteristic black glitter.

Intense alkaline hydrolysis of water-coal mixture begins when the alkali dose from about 1% to about 7.5%. At the dose of alkali is less than 1% not observed a “thickening” of the mixture, and when the alkali dose of more than about 7.5%, you receive an excess of alkali, resulting in the pH of the resulting reagent increases sharply and exceeds safe for biological objects the pH value.

The optimum quantity of caustic soda is about 3.8% of dry matter by weight of the original coal (S. C.), and potassium alkalis and 4.4%. The pH value of the obtained paste is about 7.2.

When used as alkali ammonia (aqueous ammonia with a concentration of 24%) formation of a pasty mass with a pH of about 8 occurs at a dose of about 7.5 liters (24% solution), which is about 7.5% by weight of coal. The resulting pasty product is the product obtained paste-like consistency are introduced with stirring and nitrogen-containing substance, for example, ammonium nitrate, or urea, or ammonium sulfate, or nitrophoska. In all cases observed salustiana the target product and the decrease in pH from about 7.2 to about 6.5.

Example 4

Assessment opportunities gumina-mineral reagent is performed on the sample of brown coal deposits “Maritsa-East” (Bulgaria). Due to the limited sample determine the content of natural hydrated humic acids, which is 44.5%, and the humidity W0=29%. After hydration with hot water and hydrolysis with caustic soda obtained characteristic gumina-mineral reagent with a humidity of 59% and a pH of 7.2.

Example 5

Assessment opportunities gumina-mineral reagent carried out on samples of peat Shaturskaya field. The content of natural hydrated humic acids 38%; the content of the gross and mobile forms of heavy metals does not exceed the EQS set for soils. The content of bitumen and wax 8%. The original humidity of 45%.

The peat was dried to a moisture content of 35% and was crushed to a particle size of 0.5 to 3 mm, and then was loaded into a reactor and subjected to hydration and alkaline hydrolysis under vigorous stirring and vibro-acoustic effects. It is established that PR is th water-peat mixture, then gumina-mineral reagent dense plastic consistency.

When the content of the peat 40% and the consumption of alkali 6% received gumina-mineral reagent with a humidity of 60% and a pH of 7.8.

Offer a new product - gemino-mineral reagent (hereinafter GMPs) can be successfully used for solving a number of engineering and environmental, industrial, and agricultural problems.

Thanks to the present invention have been possible without the use of expensive chemicals and materials effectively carry out reorganization (detoxification) of contaminated soils and lands.

For this GMPs in the amount of from about 0.1 to about 5% applied to the soil contaminated with inorganic (heavy metals) and organic (hydrocarbon oil and oil products, and polychlorinated polycyclic organic compounds and other) toxicants, and mix with soil to a depth of root layer (typically 20-30 cm) or deeper (over 30 cm) ploughing, disking or ripping.

While heavy metal ions effectively interact with humic acids and humates with the formation of water-insoluble compounds. Associated heavy metals lose their ability to migrate in the soil is lots gumina-mineral and mineral (mainly clay) GMR components.

Adsorption to humic acids, gumina-mineral components occurs on the type of hydrophobic interactions and covalent binding. After that, processes are oxidation - hydroxylation of hydrocarbons, including polychlorinated polycyclic compounds.

Adsorption of organic pollutants on mineral (clay) GMR components occurs due to the surface physico-chemical mechanisms of interaction.

All this translates organic ecotoxicants from a relatively stable state to microbiological degradation state.

When significant levels of soil contamination inorganic and organic ecotoxicants microflora is in a depressed condition and have little capacity to influence xenobiotics. Since the main components of the GMPs are essentially organic soil components, i.e. environment, which live and grow well in soil, including hydrocarbon-oxidizing microorganisms, to the extent of its application creates conditions for increasing the activity of ICRI is actively destroy the adsorbed ibid organic compounds and partially translate them into specific soil organic matter - the humus.

Along with called detoxification of pollutants and remediation of contaminated soils, the application of GMPs provides improved soil structure, increases the exchange capacity of the soil sorption complex, increases water-holding capacity and improves soil fertility.

As part of GMPs can be heavy metals or hazardous organic xenobiotics (benzo(a)pyrene) in quantities in excess of MPC, the application of GMPs for rehabilitation of soils, even in large quantities does not cause any negative consequences.

Thanks to the present invention have been made possible without the use of large amounts of different materials, substances, and soil effectively carry out detoxification of wastes from mining and processing of mineral resources and reclamation of dumps of rocks and HVO-sohranilis.

For this GMPs contribute to waste and mixed waste at least to the depth of the root zone layer (20-30 cm). When handling acidic waste first restore the pH to 2-3 to 6.5-8 neutralizing material, and then make GMPs in the amount of from about 0.1 to about 10% by weight of waste in the rooting zone. In addition, after restoring the pH of the waste and in the olden days of heavy metals with the formation of vodone-soluble compounds, forms complexes with anions adsorb organic and mineral substances, forms a solid units of clay and clay-sand minerals, promotes the aggregation of fine particles in agronomically valuable aggregates, increases moisture, stimulates the activity of soil microflora, improves growth and development of plants.

GMR acts as a powerful biogeochemical agent, the interaction of gumino-mineral substances with mineral and organic substances in waste and native microflora provides effective detoxification of waste formation characteristic of soil-forming processes: the transformation of the original toxic waste into non-toxic original technogenic soil recovery characteristic of the soil ecosystem. When this is suppressed not characteristic of the soil microflora, such as thiobacteria and growth characteristic of the soil microflora is accelerated. GMR mixed with waste management performs all the functions of soil humus and provides optimal water, air and thermal regimes of technogenic soils and rational nutrition, growth and development of plants. Since g is not a fertilizer, the presence in obstet in vivo processes of formation of humic substances.

According to the claimed invention using luminova-mineral reagent serves to clean highly contaminated waste water.

When the wastewater in the source liquid containing soluble and insoluble organic, inorganic and microbiological impurities are introduced with stirring the above-described ruminatively reagent. When this occurs, the binding of heavy metal ions by humic acids and humates on the type of ion exchange with the formation of water-insoluble compounds, adsorption of water-soluble impurities humic acids, gumina-mineral and mineral (clay) GMR components, coagulation, and flocculation of the insoluble impurities.

After the introduction of GMPs, it is advisable to add water calcium lime (calcium hydroxide). This humates and water-soluble humic acids interact with calcium to form insoluble calcium HUMATE released from solution in the form of fine particles. Settling particles of calcium HUMATE act like a volume filtration layer which is screened to grade water and removes impurities from it.

Processed gumina-mineral reagent and calcium is the temperature value is not less than 800°C, because at this temperature, decompose humic substances without the formation of any harmful compounds or toxic gases. Dewatered sludge also compost and receive valuable fertilizer.

According to the claimed invention using GMPs are also encouraged to carry out detoxification and disposal of sewage sludge.

For detoxification and disposal of wastewater sludge source sediments mixed with GMPs to form a homogeneous mixture. While humic acids, salts of humic acids, gumina-mineral and mineral components GMR effectively bind heavy metal ions with the formation of water-insoluble compounds; adsorb organic pollutants such as petroleum hydrocarbons and petroleum products, and polychlorinated polycyclic compounds and due to the oxidation reactions-hydroxylation accelerate the process of their degradation and transformation in specific organic homoopathie substances. In the presence of GMPs organic matter precipitation mainly humiferous, not mineralized. Source GMPs and formed in the process of its interaction with ecotoxicants connection together with humified organic act like kou structure.

Associated heavy metal ions and strongly sorbed organic toxicants lose their ability to migrate, thus preventing their penetration into the groundwater and plants. As a consequence, such sludge can be disposed of as rekultiviruemye soils for reclamation of dumps, landfills, worked-out quarries and other disturbed lands.

Having a relatively high moisture capacity, GMR holds water in the form of physically bound and immobilized water, thus providing an additional coupling of sediment particles by capillary forces. Together this leads to a drastic reduction of the rate of water filtration through a layer of sediment, and the filtration coefficient becomes equal to or less than the permeability is featured as an insulating soils, clays and loams (filtration rate of 10-3m/day). For these reasons, this sludge can be disposed as an insulating ground for disposal of solid household and similar industrial waste.

For a better understanding of the present invention the following are examples of its implementation, which, however, do not limit for the e condenser plant, Serpukhov) and contaminated with polychlorinated biphenyls (PCBs). Soil samples taken on arable areas by means of “envelope” to a depth of 20 cm with square 100100 m

In soil samples contribute GMPs, and then produce stirring and the sample is placed in the greenhouse, where it was incubated for 60 days at a constant temperature (14°C) and humidity (70% of the full capacity of the soil). Dose GMR is from 0.1 to 10% dry matter by weight of dry matter of soil. As a control using soil samples, in which GMPs are made. Repetition is fourfold. The source levels of PCBs ranges from 0.12 to 300 mg/kg

Found that in samples with low PCB content (average value of 0.12 mg/kg) for 60 days after treatment, the PCB content was decreased by 40-50%. The most effective reduction of PCB concentrations was observed in the range of applied doses of GMPs from 0.3 to 5%. When the content of GMPs more than 5% significant difference was not observed (except for the effect of “diluting” soil samples).

Also found in soil samples with high PCB content (average value of 300 mg/kg) within 60 days, the PCB content was decreased by 30-34%.

It is noted that with increasing temperat within 60 days decreased by 60-70%, while maintaining soil samples with high PCB content (average value of 300 mg/kg) PCB concentration decreased during the same period of time by 40-50%.

Example 7

As a result of industrial activities, as well as storage and disposal of household and industrial waste on certain land was unfavorable ecological situation, which consists, mainly, in high levels of contamination of soils with heavy metals.

Was carried out sanitation works (detoxification) is one of such areas, in Moscow.

To select the optimal dose of GMPs on the site, subject to readjustment, were established experimental plots, each 1x1 m plot No. 1 made 1% GMR (S. C.) by weight of the soil to a depth of 20 cm, plot No. 2 - 1.5% of GMPs, plot No. 3 - 3% GMPs, as allotment No. 4 was used as a control.

After making GMPs plots were precapitalist to a depth of 20 cm so that GMPs were uniformly distributed along the profile of the contaminated soil. Each plot was irrigated with water (8-10 l/M2and then by the method of envelope samples were collected for chemical analysis.

Due to the fact that soil humic the evaluation of the effectiveness of rehabilitation treatments were determined concentration of metals, in mobile form. The sampling results are presented in table 1.

As can be seen from table 1, set for soils MAC values are achieved with the application dose of GMPs from about 1.5%. Sharply reduces the content of heavy metals, are able to migrate into the aquatic environment and plants. For optimal dose GMPs, equal to 1.5%, reorganize area of 1.8 hectares, soil Samples were taken before and after the rehabilitation of the territory with the use of GMPs. The effectiveness of rehabilitation works are shown in table 2

Analysis of the obtained experimental data on rehabilitation treatment of contaminated site allows to make a conclusion about the effectiveness of the remediation of soils:

the content of mobile forms of cadmium, Nickel, arsenic is reduced to 5-6 times;

the content of mobile forms of chromium and strontium is reduced 4 times;

the content of mobile forms of lead, silver, tin, cobalt is reduced 3 times;

the content of mobile forms of zinc and copper - 2 times, vanadium and antimony 1.5 times.

The content of manganese, strontium, zinc, copper, lead, cadmium, Nickel, chromium, arsenic, silver, vanadium, antimony and tin in all samples of the soil Plaszow tailings copper ore mining and processing plant “Asarel-Medet” (Bulgaria), selected with the “oxide” blade (sample No. 1) and “Eastern” embankment (sample No. 2).

The copper content in the sample No. 1 was an average of 500 mg/kg at pH of 3.7, the copper content in the sample No. 2 averaged 700 mg/kg at pH 3.5.

Neutralization of the acid reaction of the samples was carried out by adding slaked lime. It is established that increase the pH of the samples with a 3.5-3.7 to almost neutral pH values of 7.8 to 8.5 was achieved at a dose of lime equal to approximately 0.4% of dry matter dry mass of the samples. However, over time the pH of lime treated samples fell sharply. For example, the pH of lime treated sample No. 1 was decreased from 8.5 to 6.2 within 21 days, and the pH of the sample No. 2 at the same time from 8.2 to 4.2.

It was also established that if, after neutralization of the acid reaction samples by adding them hydrated lime in an amount of 0.4% and bringing the pH of the samples to 7.5-8.5 in the samples to enter GMPs in the amount of from 0.15 to 12%, then there is a much smaller decrease in pH. In the range up to 10%, the higher the content of GMPs in samples, the less the decrease in pH. For example, when the content of GMPs 0.15% on dry matter dry mass of the samples No. 1 pH decreased 21 days from 8.5 to 6.2; when the content of GMPs to 1.5% pH dropped the CLASS="ptx2">

The efficacy of detoxification of waste represented by the samples No. 1 and No. 2, were conducted at making hydrated lime (0.4% by weight of sample) and slaked lime (~0.4%) and GMPs in the amount of from 0.15 to 10%. Determination of the toxic effects of waste on the development and growth of plants before and after application of lime and lime with GMPs was conducted in accordance with the international standard ISO 11269-2. Were determined in changes in species composition of microorganisms after application of lime and GMPs. The results of the research, including germination plant (for example, barley), average height, biomass is presented in table 3.

Note: table 3 shows the data for dose make GMPs, 0.75, 1.5 and 3%. When the application dose of from 0.15 to 1.5%, there is a smooth increase in the efficiency of detoxification of waste, which reaches maximum values at doses of GMPs from 0.75 to 10. The exposure time is 21 days (up to the stage of the second sheet).

As can be seen from table 3, the most toxic are wastes of sample No. 2. These wastes does not occur even germination. Application of lime reduces the toxicity part. For this reason, samples No. 2 as passed the seventh option with the introduction of ISI and GMPs.

Previously all samples were made on 1 g of the suspension of sod-podzolic soil as the carrier of a typical soil microorganisms. In the original (not processed) samples revealed a large number of sulfur bacteria of the genus Thiobacillus ferooxidans and Leptospirillum ferooxidans. After processing the reactive sulfur bacteria not detected. There is a large number of typical soil microorganisms Psevdomonos, Azotobacter and yeast-like microorganisms of different forms: rod-shaped, arrow-shaped, cylindrical.

Thus, the introduction of GMPs in the samples on the background of lime stabilizes pH, reduces the toxicity of waste, ensures the normal development and growth of plants, inhibits ceramictile and activates the growth and development of typical soil microflora, primary forms fertile soil, increases its moisture and forms a typical soil biogeochemical processes, i.e. provides an efficient detoxification of waste and reclamation of mine dumps and tailings.

Example 9

Were hydrometallurgical tailings detoxification (electrolysis) zinc production (Brazil).

Waste was formed after roasting zinc concentrate, Vyselki the ka and its neutralization with lime. Wastes are dispersed mass of red-brown color. The average content in the waste zinc was 1470 mg/kg, aluminium - 64 mg/kg, cadmium - 9 mg/kg, Nickel - 0.8 mg/kg, copper 0.5 mg/kg and lead - 0.4 mg/kg when the actual pH of 6.2 to 6.5.

In the original samples of the waste were added different amounts of GMPs: 0,15%, 0,5%, 1,5%, 3%, 6%, 8% and 10% by weight of dry matter waste. As a control we used the sample of waste without making GMPs. The effectiveness of detoxification was determined by the method of biotesting on the international standard ISO 11269-2. As the test culture was used barley in quadruplicate of each option.

It is established that in the control samples germination of seeds almost didn't happen: barely emerged seedlings were quickly killed. Starting with a dose of 0.15 per cent, of the seeds appeared sustainable growth, the development of which, however, was rather slow. With increase in the content of GMPs in waste plants grew faster. Table 4 shows the effects of GMPs on plant growth.

Biometric data from table 4 are in good agreement with such an important agrochemical and biological indicator, as the increase in biomass p is eveden dry biomass).

Positive results caused by both the effects of detoxification of waste by binding of ions of zinc and other heavy metals, and the effects of biostimulation and protective actions GMPs on plants.

In addition to the significant reduction and elimination of waste toxicity, GMR significantly improve the physical properties of the waste and give them valuable agronomic quality, turning waste into primary fertile soil, ensuring normal growth and development of plants. This formed the characteristic of the soil absorption capacity, buffering capacity, water-holding capacity, structure, i.e. processed GMR waste can be classified as soil. Moreover, with increasing doses of GMPs to 8-10% and above waste is increasingly the quality of primary fertile strongly houseruling soil.

Modeling of tailings reclamation was carried out on a special stand in the form of a rectangular box with dimensions 0,50,75 m and a depth of 0.35 m Box was filled with waste, then the waste is compacted. After 2 weeks of keeping waste crumbled to a depth of 0.2 m and there has been GMPs (3%).

It is established that stabilization of the main physico-chemical p is the group of effective growth and development of grass, good condition its root system, the formation of the main characteristic of soil biogeochemical processes.

Example 10

Was clearing manure effluent pig-breeding complex “Red Beam” (Moscow region). Manure runoff generated during dredging cleaning pig manure and represent liquid dark green color mixed with feed and a characteristic odor. The filing of such effluents after quarantine cure for mechanical-biological treatment plants leads to failure of the biological part of the treatment facilities due to the high toxicity of the effluent. In this regard, the task was in the pre-treatment of wastewater and bringing them to the rules that allow their subsequent biological treatment.

In the sample source of waste liquid introduced under stirring GMPs, then the same sample was made of lime in the form of lime milk and defended. After settling, the treated water is separated from the precipitate.

Preliminary proximate analyses, including determination of the transparency, color, odor, amount of suspended solids and others, found that the cleanup of such runoff begins to occur in ulitsa transparent with a slightly yellowish color and hardly distinguishable odor.

For a specific volume of the original waste liquid measure chemical oxygen demand (COD) 1440 mg/l introduction of GMPs in the amount of 1.5% (by weight of the waste liquid and lime in the amount of 0.5% (by weight of waste liquid) produces almost transparent, odorless liquid with a COD of approximately 160 mg/l, this liquid is further effectively cleaned before COD, equal to 12-18 mg/l on the biological part of the treatment facilities.

Example 11

Conducted cleaning of the filtrate, i.e. the waste fluid flowing from the body of the landfill disposal of solid household and similar industrial waste “Sapareva” (Moscow region)

Preliminary tests it was found that the most effective cleanup occurs in the concentration range GMPs from about 1 to about 3% (S. C.) by weight of the purified filtrate and lime from about 0.3 to 1% by weight of the filtrate. Characteristics of the source and purified filtrate at a dose of GMR 1% lime and 0.3 percent are shown in table 6.

Example 12

Creating rekultiviruemye layers on the surface of the landfill of solid domestic and industrial waste in the mined-out space ka is adnych and soils as rekultiviruemye soils can be used municipal wastewater sludge (WWS). Restrictive reasons for such disposal WWS are dusting that occurs when dry salt, and high levels of heavy metals and other toxic substances.

Laboratory tests have proved that if the dusting of dry salt begins at an air velocity of 1.5-2 m/s, while the introduction of GMPs dusting decreases sharply. So, if you already have a sufficiently small content of GMPs in WWS (approximately 0.1 to 0.15%) threshold dusting 2-3 times, that is, the salt begins to dust when the air flow rate of 3-6 m/s When the content GMPs about 1% threshold of dust rises up to 12-15 m/s After mixing the salt with GMPs is a significant change to their properties and structure. Processed salt become essentially soils.

The resulting layer of this soil was placed on the surface of the body of the landfill, and then were sown the seeds of lupine and barley. After maturation of the plants was determined by their content of heavy metals (see table 7).

As can be seen from table 7, after processing, the salt of gumino-mineral reactant heavy metals in plants is dramatically reduced, which indicates their effective binding and loss of mobility.

Premeal from 0.1 to 10%. After processing, the WWS were laid in trays of size 0,h,75 m and a depth of 0.35 m Standard method of irrigation water in the pit using devices Boldyreva, A. K., and Kaminski, N. determined the filtration coefficient after the steady flow of water.

It is established that close to clays and dense loamy permeability coefficient (310-4m/day) treated salt occurs with the minimum content of GMPs from 1 to 3%. That is, when the content in salt, gumina-mineral reagent at a level of 1-3% of such salt can be recycled instead of clays and heavy loams as an insulating soil.

In order to check the stability of raw and processed salt to microbiological degradation of salt was placed in a layer with a capacity of 0.3 m in the body of the landfill at a depth of 2.5 m Criterion was the content of humic acids in the original salt (not processed) and processed GMR precipitation after 2 years of aging in the body of the landfill. The content of humic acids was determined by their access standard method.

Contents humanophobia substances in the original salt is approximately 0.4%. Raw salt in 2 years content humanophobia substances amounted to 1.6%. In education is, the processing of salt reagent leads to preferential humification (synthesis), and not to mineralization (decomposition) of organic matter WWS, which increases the value of the processed reagents salt as insulating substrates.
