The invention relates to applied electrochemistry and can be used for cooking liquid antioxidant (Catolica), which can be used in medicine, veterinary, agriculture, food industry and many other fields of human activity.

A method of obtaining antioxidant (Catolica), processing leading to a cathode chamber of a diaphragm electrolytic cell until Catolica values of oxidation-reduction potential (redox potential) Eh within -(+150÷-950) mV [1].

The disadvantage of this stimulant is that it is not optimal for most biological objects the relationship between pH value and pH value redox potential Eh. Catholyte from the water, which has a pH equal to 7.0, has a pH value greater than 7.0. Thus, the lower the negative value has a redox potential of Catolica, the higher stimulating properties it possesses. According to [2] optimal stimulator-antioxidant for humans is water, which must have (pH)* 8; (Eh)*=(-250)÷-(350) mV, HSE (in terms of platinum electrode in the silver chloride reference electrode).

In natural water redox potential is usually equal to +200...+400 mV at pH 7. Therefore, drinking water does not render article is Malinowska effect on the organism of man and animals. The anolyte antioxidant properties does not possess.

Known household diaphragm electrolyzer for receiving Catolica (live water) and anolyte (dead water)containing waterproof case-vessel (glass jar), a rectangular anode and cathode electrodes, made of stainless steel (related to the base conducting material and mounted on the dielectric housing cover-receptacle, a semiconductor rectifier diode, mounted on the dielectric cover and connected cathode to anode electrode, waterproof canvas bag, placed in the body-vessel, which, in turn, is placed in the anode electrode, and a two-wire cord, the first the end of the first wire which is connected to the anode of the diode, the first end of the second wire is connected to the cathode electrode, and the second ends of which end with a fork, included in the AC voltage of 220 V [3].

The disadvantage of this device to obtain antioxidant (Catolica) is the low efficiency of water treatment, due to the impossibility of providing the optimal combination of hydrogen ion exponent pH value redox potential (redox potential) Eh, you want to stimulate the activity of various biological objects.

Known SP is a way to obtain the activated water based on water electrolysis in a diaphragm electrolytic cell for the time required to obtain Catolica with a pH of 9.5÷11,0), and further mixing the obtained Catolica with part or all of the received analyte [4]. This method allows to obtain an optimal balance between pH and Eh than the correlation between pH and Eh in catholyte. For example, a mixture of Catolica and anolyte obtained from tap water, whose pH value was equal to 7.2, a Eh=+200 mV, had a pH of 7.2, a Eh=-350 mV.

The disadvantage of this method is, firstly, that in a mixture of Catolica and anolyte cooked in a common diaphragm electrolytic cells, the anode of which is made from a base of conducting material (e.g. stainless steel), are harmful for a number of biological objects ions, open the electric field at the surface of the anode, and this mixture is unsafe to take into the body. Secondly, the anolyte is nonequilibrium oxidant (electron acceptor), which for all its pH value Eh is rejected relative to its equilibrium value towards large positive values. This narrows the range of obtained values Eh mixture at each pH value (reduces the range of the antioxidant properties of the mixture). The need to have liquid antioxidant in a wide range of pH values is caused by a variety of biological objects, and each object is the diversity of its bodies, in particular the mucous membranes, in which the processes occur normally at different pH values. So, some plants prefer a neutral soil, other - slightly acid or slightly alkaline. Microbes are best developed in the range of pH 7.0÷7.4V. Optimal value of pH is the pH value equal to 8, and the redox potential of not more than minus 250 mV [2]. If the mixture of liquid stimulant-antioxidant is designed to feed the bees, it is the optimal value of pH pH is equal to 9, and the redox potential of not more than minus 250 mV [2].

Known dual (three) electrolyzer flow type [5], which contains a source of low voltage, the node for electrochemical water treatment and supply of treated water to the site for electrochemical treatment of water, and the node for electrochemical treatment of water contains a graphite anode, a cathode and a stainless steel cathode and the anode chamber, the middle chamber filled with an electrolyte separation membrane, a protective membrane, a current supply, the input of water-salt solution and the output of the activated solution in the tanks collection of anolyte and catolyte.

Using a three-chamber electrolytic cell with an ion exchange membrane provides additional capacity and to control the physicochemical properties of the treated solutions. Thus there is a possibility to change the length of an average camera, setting the intermembrane distance on the order of magnitude smaller than the linear dimensions of the anode and cathode chambers. Due to this arrangement of membranes in electrolysis processes, which are typical when using bipolar membranes, which play the role of "generators" of hydrogen and hydroxyl groups. When used in a three-chamber electrolyzer membrane electrolyte concentration in the volume of the cation-anion exchange resin" is decreased due to the migration of cations and anions from the space between the membranes, which leads to an increase in the electrical resistance of the volume of the middle chamber. In such circumstances, the further passage of current is provided mainly by the migration of hydrogen and hydroxyl ions formed by the dissociation of water. In the middle of the camera (to a lesser extent in other cameras) changes patterns, break hydrogen bonds, dissolved associates molecules, an increasing number of more active monomolecules.

The disadvantage of this device is the need for additional separation of ion-exchange membranes, additional chemical reagents, in particular water-salt solutions, which complicates the design of the device.

In addition, the diaphragm electrolyzer necessary elements stored what is aperture, which in the process becomes clogged ions, pulling out from the anode, and various impurities present in water, which affects the mode of operation of the electrolyzer and the quality of the activated water.

There is also known a method for obtaining Catolica-antioxidant, which consists in electrochemical water treatment, as well as a device for its implementation, including the site of the electrochemical water treatment system for supplying water to be treated in the electrochemical host and reservoir for collecting Catolica [6].

The disadvantages of the prototype method and device of the prototype are that not all processed water is converted into the catholyte is an antioxidant, but only part of it. Another part of the treated water is converted into electrochemical activation in the anolyte. Prototype method and device-the prototype are the diaphragm, the pores of which during electrolysis driven side of the substances in the water, and the cathode overgrown cathode deposits that requires constant cleaning or change, which complicates the device and the implementation of the method. In addition, the method and the device difficult to obtain without the addition of various salts in water and mineral supplements high (in absolute value) negative values of the redox potential, which reduces antioxidant properties obtained for the of out this fascinating site.

The technical problem on which the invention is directed, is processing all of the treated water in the catholyte is an antioxidant, to simplify the method and device, in increasing the antioxidant properties of Catolica-antioxidant, by achieving higher (in absolute value) negative values of the redox potential.

Liquids with antioxidant refers to liquid, from which the values of the redox potential Eh when data values of pH pH is shifted in the negative direction relative to the Eh values of the liquids are in equilibrium with the environment. Liquids-oxidants (electron acceptors, oxidants) refers to liquid, in which the Eh values at these pH values are shifted in the positive direction.

Figure 1 presents a diagram of the device for receiving Catolica-antioxidant that implements the inventive method.

Device for receiving Catolica-antioxidant (figure 1) includes the site of the electrochemical water treatment 1, the supply of treated water 2 in electrochemical node 1 and the collecting tank Catolica 3. In the device additionally introduced the hermetic vessel 4, booster pump 5, vacuumoperated 6, the vacuum gauge 7 gauge 8, the vacuum valve 9, a balloon of hydrogen 10, ed is ctor 11 pressure gauge 12, the supply line to the hydrogen 13 with the gate 14 and the source of the regulated high voltage 15. Site for electrochemical treatment of water 1 made in the form of a conical funnel 16 of inert material is polystyrene. The funnel 16 is located vertically so that the larger base of the conical funnel facing up, and the smaller base of the conical funnel facing down. The upper base of the conical funnel plugged with a lid 17, which is made of electrically conductive material in the form of a disk. To the Central part of the upper cover 17 of the conical funnel 16 is attached needle electrode 18, passing inside the funnel on its Central axis of symmetry. The bottom base of the conical funnel 16 is closed by a cover 19 made of inert organic material is polystyrene. In the lower lid 19 in the center is a through hole, which extends the sharp end of the needle electrode 18. In the side of the conical funnel 16 is hermetically mounted pipe 20 for supplying water into the funnel 16. The pipe 20 is connected the supply of treated water 2. On the outer lower part of the forming surface of the funnel 16 is a ring electrode 21, covering the Cup and in contact with its external surface. High voltage negative output of a source of regulated high voltage 15 is connected to the ver is it the cover 17 of the conical funnel 16, and the positive output of a source of regulated high voltage 15 is connected to the ring electrode 21 and grounded. Booster pump 5 through vacuumoperated 6 with the valve 9 communicates with the internal cavity of the sealed vessel 4. Vacuum sensor 7 is embedded in vacuumoperated 6 and connected to the vacuum gauge 8. The balloon with hydrogen 10 through the gear 11 with the pressure gauge 12, the supply line to the hydrogen 13 with valve 14 communicates with the internal cavity of the sealed vessel 4. Moreover, the supply line to the hydrogen 13 in the catholyte is a pipe, the outlet of which is located at a distance of not more than 2 mm from the bottom of the sealed vessel 4. A reservoir for collecting Catolica 3 is located under the lower base of the conical funnel 16 and through the water pipe 22 with the valve 23 is connected with the hermetic vessel 4. Into the hermetically sealed vessel 4 introduced the drain pipe 24 with the valve 25.

The essence of the invention is as follows.

Negative high-voltage source output regulated high voltage 15 (figure 1) is connected to the top cover 17 of the conical funnel 16. The positive output of a source of regulated high voltage 15 is connected to the ring electrode 21 and kasemset. A negative high voltage potential through the conductive top cover 17 is fed to the needle electrode 18. The treated water flows from the system which we water supply 2 through the pipe 20 in the conical funnel 16. Because the needle electrode 18 filed the negative potential from the high voltage source regulated high voltage 15, with the passage of the particles of water along the surface of the needle electrode 18 occur following physical processes.

A water molecule in a simplified form can be represented in the form N+HE-. Because water is a polar liquid, water molecules in contact with the negative electrode, polarizing (deformed)than the others are positively charged ion of hydrogen to the electrode. Therefore, water molecules, approaching the needle electrode 18, are polarized and turn into dipoles.

This "deformation" of the water molecules increases with the approach to the top of the needle electrode 18, where the field strength is significantly higher than near the other part of the same electrode. Under the influence of an electric field causes dissociation of water molecules into positively charged hydrogen ion H+and negatively charged hydroxyl group HE-. Positively charged hydrogen ion H+pulls an electron from the surface of the electrode 18 (in the case of the cathode). This electron will neutralize positively charged ion N+and ion becomes a neutral atom. The hydrogen atoms are connected in the molecule H+H=H2and the hydrogen separation is seen in the environment. In water that has passed along the surface of the internal cavity of the high-voltage negatively charged electrode, accumulate in excess of negatively charged ions hydroxyl group HE-. The treated water at the outlet of the conical funnel 16 becomes alkaline in nature, turning into the catholyte. Change the value of the negative high voltage to the needle electrode 18 can continuously vary the amount of hydrogen ion exponent pH in the range from 7 to 11. Catholyte from the hopper 16 is supplied to the tank 3 to collect Catolica. In General, despite the high values of pH the pH obtained catholyte has mild antioxidant properties, or do not have them. Antioxidant properties of water depend on the magnitude of the oxidation-reduction potential (ORP), or as it is called the redox potential Eh. If the redox potential of the liquid is shifted to positive values, then the fluid is an oxidant (electron acceptor, oxidant). If the redox potential of the liquid is shifted to negative values, the liquid acquires the properties of an antioxidant (an electron donor, a reducing agent).

It should be noted that the greater shifted the redox potential of the liquid in the region of negative values, the higher the antioxidant the properties of the liquid.

In order to give the resulting Catolico antioxidant properties, it should be further processed in such a way as to shift the redox potential in the area of negative values. This is achieved by saturation of the received Catolica hydrogen. Saturation Catolica hydrogen is as follows. Include booster pump 5 and open the vacuum valve 9. When this valve 14, a built in system of hydrogen supply, and valves 23 and 24 are closed. Booster pump creates a vacuum in the sealed vessel 4. Creating a vacuum in the vessel 4 is necessary to achieve two goals: first, removal of the sealed vessel together with air, hydrogen, and, secondly, for a smooth filling Catolica sealed vessel. Oxygen from the sealed vessel must be removed because it is an oxidizer, and his presence in the hermetic vessel 4 will lead to an increase of the redox potential towards positive values. The degree of vacuum in the hermetic vessel 4 is controlled by the 8 gauge vacuum gauge 7. The amount of vacuum in the hermetic vessel 4 is sufficient to maintain in the range (5-10) Torr. The higher the dilution of the value of less than 5 Torr is impractical because it requires additional measures to ensure the integrity of the vessel. If you create the vacuum inside the sealed vessel 4 to a value greater than 10 Torr, this can lead to undesirable high content of residual oxygen in the environment of dilute gases. When reaching inside the sealed vessel rarefaction in (5-10) Torr block the vacuum valve 9 and opening the valve 23. Due to the differential pressure in the tank 3 to collect Catolica and in the hermetic vessel 4 catholyte through the water 22 begins to flow from the reservoir 3 into the hermetically sealed vessel 4. After filling in a sealed vessel at (95÷97)% of the volume of its cavity close the valve 23. Incomplete filling of the cavity of the sealed vessel is necessary in order above the amount of the fused Catolica it was possible to create a hydrogen atmosphere. When filling the volume of the cavity sealed vessel less than 95% of the volume of the internal cavity of the sealed vessel, reduces the volume of processed Catolica, and when filling more than 95% of the volume of the internal cavity of the sealed vessel reduces the amount of hydrogen located above Catolica. Both that, and another leads to a decrease in the efficiency of processing Catolica hydrogen. After closing of the valve 23 to open the valve 14 serving for the supply of hydrogen in a sealed vessel 4. Hydrogen from a balloon with hydrogen 10 through the gear 11, the open valve 14 and the supply line to the hydrogen 13 starts to arrive in a sealed vessel 4. The hydrogen comes from the opening line 13. The CTE is the participation line 13 should be close to the bottom of the sealed vessel 4 at a distance of not more than 2 mm The distance is not more than 2 mm must be maintained in order emerging from holes backbone hydrogen passed through almost the entire thickness of Catolica poured into a sealed vessel 4. Hydrogen in a sealed vessel 4 to fill until the pressure in the sealed vessel above the amount of the slit in his Catolica will not reach the value (900÷1000) Torr. To increase the pressure above 1000 Torr is impractical because it leads to inefficient cost of hydrogen. Reducing the pressure over the region, less than 900 Torr, may degrade the efficiency of processing Catolica hydrogen. When reaching into the sealed volume of the pressure value (900÷1000) Torr, as evidenced by the pressure gauge 12, close the valve 14 and prevent further access of hydrogen in a sealed vessel 4. After exposure of Catolica for at least 3-5 hours catholyte becomes antioxidant properties and it can be used for the stimulation of human, animal, plant.

An example of a specific implementation.

Was completed device to obtain Catolica-antioxidant (Fig 1.), which included the site of the electrochemical water treatment 1, the supply of treated water 2 in electrochemical node 1 and the collecting tank Catolica 3. In the device additionally introduced the hermetic vessel 4. The vessel was made because of the glass bulb, the internal volume of which was 2 liters. As a booster pump 5 was used pump brand BH-461. Vacuumoperated 6 was made of rubber vacuum hose, inner diameter of which was equal to 8 mm as a vacuum sensor 7 was used thermocouple sensor LT-2. As of 8 gauge was used gauge VIT-2. The role of the vacuum valve did the customary mechanical, pinching the rubber vacuumoperated 6. As the cylinder under the 10 hydrogen was used ordinary cylinder of compressed gas with gear 11, a typical valve 14 and 12 gauge. The supply line to the hydrogen 13 was made of copper tube with a diameter of 5 mm as a source of regulated high voltage 15 was taken universal punching install the UPA-1A. Site for electrochemical treatment of water 1 made in the form of a conical funnel 16 is made of polystyrene. The height of the funnel was equal to 20 cm, the upper base is 15 cm, and the lower 4 see Funnel 16 is positioned vertically so that a greater base of the conical funnel 16 has been drawn up, and its smaller base was turned down. The upper base of the conical funnel plugged with a lid 17, which was made of steel in the form of a disk. To the Central part of the upper cover 17 of the conical funnel 16 is attached needle electrode 18, carried out the steel rod with a diameter of 5 mm The needle electrode 18 were inside conical funnel 16 to its Central axis of symmetry. The bottom base of the conical funnel 16 has been closed by a cover 19 made of polystyrene. In the lower lid 19 in the center is a through hole with a diameter of 8 mm, in which came the sharp end of the needle electrode 18. In the side of the conical funnel 16 was tightly encased pipe 20 for supplying water into the funnel 16. Nozzle 20 has been connected, the supply of treated water 2, which represents the normal water. On the outer lower part of the forming surface of the funnel 16 is a ring electrode 21, covering the lower part of the conical funnel 16 in contact with its external surface. High voltage negative output of a source of regulated high voltage 15 was connected to the top cover 17 of the conical funnel 16, and the positive output of a source of regulated high voltage 15 was connected to the ring electrode 21 and grounded. Booster pump 5 through vacuumoperated 6 with the valve 9 has been reported with the internal cavity of the sealed vessel 4. Vacuum sensor 7 was built in vacuumoperated 6 and connected to the vacuum gauge 8. The balloon with hydrogen 10 through the gear 11 with pressure gauge 12 and through the supply line to the hydrogen 13 and a valve 14 communicating with the internal cavity of hermeti the tion of the vessel 4. Moreover, the supply line to the hydrogen 13 in the catholyte consisted of a pipe, the outlet of which was located at a distance of 1 mm from the bottom of the sealed vessel 4. A reservoir for collecting Catolica 3 was located under the lower base of the conical funnel 16 and through the water pipe 22 with the valve 23 is connected with the hermetic vessel 4. Into the hermetically sealed vessel 4 was introduced the drain pipe 24 with the valve 25. On the needle electrode 18 from a source of regulated high voltage 15 was filed with the negative potential value minus 5 kV. The passage of water along the surface of the needle electrode, it turned into catholyte. Sampled from the tank 3 water had a pH value pH 8. Redox potential (Eh) was measured chloride and platinum electrodes. Take into account that your own potential silver chloride electrode relative to the normal hydrogen element (nue) according to the manufacturer was +201 mV for 3M KCl solution at 20°C. For the value of the building was taken minimal countdown millivoltmeter. Hence, on the basis of the ratio Eh=E (mV)+201 mV where E is the potential, directly measured by the device, the received value Eh (relatively NVE). The concentration of oxygen dissolved in water, was determined by the Clark electrode. All smartypantses device "Expert-001" company "Econix". Using a standard silver chloride and platinum electrodes.

The redox potential of Catolica was equal to Eh=-95,4. After measurements of Catolica taken from the tank 3, was blocked by a valve 23, included a booster pump 5, open the vacuum valve 9 and created inside the hermetic vessel 4 depression.

After a hermetic vessel 4 vacuum 6 Torr blocked the vacuum valve 9 and opening the valve 23. Due to the differential pressure in the tank 3 and the hermetic vessel 4 catholyte flowed from the reservoir 3 into the hermetically sealed vessel 4. The catholyte was poured up until its level in a pressurized vessel did not reach the order of 1.92 liters. Then provided a complete seal in the hermetic vessel 4 by closing the valve 23. Then opened the valve 14, and escalate hydrogen in a sealed vessel 4 from the container with hydrogen 10 through the gear 11 and line 13. When reaching inside the hermetic vessel 4 pressure equal to 950 Torr, was blocked by a valve 14. After 3 hours opened valve 25 and through the pipe 24 has discharged catholyte, for measurement of pH and Eh in the vessel with a volume of 250 ml. pH of the mixture pH was not changed and was equal to 8. Redox potential was equal to Eh=-600 m Century.

FIELD: water-supply engineering.

SUBSTANCE: invention relates to methods of removing hardness salts from regenerates and can be used in water treatment processes in heat-and-power engineering, chemical, petrochemical, food, and other industries provided with ion-exchange water-desalting filters. Method is accomplished by precipitation of hardness salts involving recycle of precipitate treated by alkali solution followed by passage of supernatant through H-cationite filter. Treated precipitate accumulated in preceding settling cycles is recycled into regenerate and settling-subjected solution is passed through cationite filter to produce purified sulfuric acid further used for regeneration of H-cationite filters in water-treatment cycle. Precipitate is treated with alkaline regenerate from OH-anionite filters or with alkali solution obtained from electrolysis of regenerates with pH not below 11. Amount of regenerate introduced into accumulator-settler should be at least 20 kg/m3.

EFFECT: excluded liming procedure, preserved initial (after regeneration of filters) content of sulfate ions in sulfuric acid, reduced consumption thereof during preparation of regeneration solution, and excluded discharge of sulfate ions unto water objects.
