The invention relates to engineering systems for water purification and disinfection, and more specifically to systems for effective cleaning and disinfection of natural, mostly underground waters by oxidation with ozone water pollutants and intensification of processes of cleaning and disinfection of the treated water.

It can be used, in particular, to improve sanitary and epidemiological safety systems of drinking water supply of rural settlements of the ground water intake, enterprises of various industries, summer camps, camping sites and holiday villages.

The famous "water supply System" (USSR author's certificate on the invention of SU # 1.020.529, CL EV 1/02, 1981, Sankin NF and others).

The water system consists of a pipeline replacement-regulating tanks, water towers, distribution networks, hydro-pneumatic water lift, which consists of two tanks with valves, duct, piping, circulating pipe and ejector with valve.

In known water system ensures a constant water withdrawal from replacement-regulating reservoir to a water tower, from which the water enters the distribution network, and replenishment spare and regulating reservoir with water from the water supply under positive pressure, so what. there is a constant circulation of water in the tank. The ejector with valve are used for extra unmetered air into the system.

The main disadvantage of the water supply system is its lack of sanitary-epidemiological reliability due to the absence in it of nodes cleaning and disinfection of source water.

Known technical solutions, including the integrated use of the effect of spin water and air to create a deeply dispersed emulsion having a low density compared to the density of water, providing intensive oxidation of chemical contaminants oxygen, improving water quality and reducing energy costs on the rise of water and uninterrupted water supply (patent RU №2.166.029, CL EV 1/02, EV 3/04, "water supply System of the locality", 2001, Viktorov, GV and others; RU patent No. 2.195.533, CL EV 1/02, EV 11/10, "water supply System", 2002, Viktorov ONWARDS and patent RU No. 2.195.534, CL EV 1/02, EV 3/06, "water supply System of settlements, 2002, Viktorov, GV).

The main disadvantage of the above-mentioned water systems is the lack of sanitary-epidemiological reliability due to the absence in them of nodes cleaning and disinfection of source water.

It is known Device for water purification from iron" (the author is the certificate of the USSR to the invention SU # 1.502.481, CL C02F 1/64, 1989, Rechtin A.F., and others), consisting of a housing, the filter loading and cavitator, made in the form of a cylinder, a piston and a vibrator. With the help of the cavitator are low-frequency oscillations, causing cavitation bubbles, which, shapeways, convert ferrous iron to ferric, which is deposited on the filter loading.

The disadvantages of the known devices for water purification are the low efficiency of aeration and low reliability of the cavitator, because vibrators often fail due to rapid wear. Wave compression-tension arise in the gap between the walls of the device and of the cavitator. This volume is very small, the number of bubbles is also low, and thus the efficiency of water treatment is low. The device is designed to create a cavitation effect and filter, providing clean water. The combination of these two functions in one housing attractive, but at the same time causes the following negative consequences: lack of oxygen and the short time of contact with pollutants contained in the water, and the absence of conditions for the creation of small bubbles of water vapor and gas lead to the fact that the divalent iron is badly enters trivalent. The device does not allow to achieve optimal what's size and its nodes to ensure effective water purification.

It is known Device for ozonation of water" (patent RU №2.078.055, CL C02F 1/78, 1997, Volchenko Y.A. and others).

The device contains a horizontal sealed enclosure with connections to the input and output of water, separated by a vertical wall of the contact chamber and degassing chamber. In the contact chamber is placed horizontal, parallel, alternately shifted partitions and dispersion of ozone-air mixture, made of porous tubes installed along the guide rails, chutes, located in the bottom of the contact chamber and fixed blade grips. In the chamber degassing under overflow box, made in the vertical wall is tapered, perforated tray, which is tilted in the direction of the downward flow of water under the tray are at least two rows of dividers.

The treated water is pumped into the lower part of the contact chamber, where it mixes with the ozone-air mixture supplied by the system dispersion in porous tubes, and passes from the bottom up a system of horizontal partitions. Ozonation of water is carried out in the flow of the treated water and ozone-air mixture by contacting bubbles of ozone, particle pollution. Contact camera stream water-ozone-air mixture enters the chamber degassing through perforirovanie tray dividers. The air containing molecules unreacted ozone, rises in the upper part of the additional section, hits disc reflector, reflecting water molecules. Purified water is pumped from the chamber of the degassing pump.

The horizontal location of the partitions in the contact chamber in combination with the dispersion made of tubes that are installed perpendicular to the flow of water and provides a thin dispersion, allows you to create the best mode of mixing water to be treated and ozone-air mixture, ensuring turbulent flow regime due to repeated turning of the flow between the partitions, and to increase the contact time to ensure full use of ozone and increase the purity of the water.

Despite the use of a number of effective technical solutions, the known device for water ozonation has the following disadvantages:

1. The complexity of the design (horizontal partitions, porous tubing, perforated tray and others), which determines the unavailability of a number of nodes for maintenance and repair and, therefore, the unreliability of the entire device for ozonation of water.

2. Unsustainable consumption of ozone-air mixture in the oxidation of large fractions of pollutants in the contact chamber due to the lack of the device for ozoni is for water pre-filtration, resulting in a decrease in the efficiency of cleaning and disinfection of source water.

3. Lack of sanitary-epidemiological reliability of the device for water ozonation due to the lack of output of the sorption unit, resulting from the treated water does not remove the products of ozonolysis, many of which are carcinogens.

The famous "Setting for ozone liquid environments" (patent RU №2.063.377, CL SW 13/11. 1996, Slusarenko EM and others), containing a source of oxygen-containing mixture, which is connected in series with the ozone generator and dispersing device, which via a pump connected to the circulation pipe to the tank for saniruemogo fluid, and the reservoir is connected through a filter drier and the camera receiver, changing the volume, ozone generator, a dispersant injection device of the type placed on the suction side of the circulation pipeline, and the pulsator or cavitator placed on the discharge side of the circulation pipeline.

With a circulation pump and two dispersant injection type in the installation is carried out intensive mixing of the ozone-air mixture from the treated water. In this case, the degree of assimilation of ozone per cycle is increased, as are formed in the dispersant bubbles of ozone-susnow mixture additionally pass through the circulation pump, working as an ideal mixing apparatus. Increase the size and duration of contact contributes to a more efficient absorption of ozone and, as a consequence, decrease the energy intensity of the process of ozonation. To increase the efficiency of absorption of ozone in the circulation loop includes the pulsator or the cavitator. The imposition of pulsating pressure on the fluid flow contributes to more intensive mixing of the ozone-air mixture in the bubbles and causes cavitation effects, contributing to the dissolution of ozone in saniruemogo fluid and, consequently, more complete absorption.

In addition, the tank saniruemogo liquid ozone-air mixture is separated from the liquid through the filter drier and the camera receiver enters the ozone generator, which is generated from a mixture of ozone and air mixture is again dispersed in saniruemogo liquid. Thus, ozonoterapia mixture circulates in the gas space of the installation which is completely isolated from the atmosphere. The circulation of the mixture is carried out until the total consumption of ozone. Installation allows you to use as a source of pure oxygen with almost 100%its conversion into ozone. Also removed the problem of utilization of ozone as an environmentally hazardous material.

The disadvantages of the known installation for ozone liquid the environments are:

1. The complexity and, hence, the low reliability of the formation of the gas space in the device for ozonizing liquids, including equipment for ozone-air mixture of pure oxygen and transporting it (the source of oxygen-containing mixture, ozone generator, the gas pipeline cycle, filter, desiccant and camera receiver).

2. The low efficiency of the cleaning fluids from pollutants due to the absence in the installation of the sorption sites. Resulting from the treated water does not remove the products of ozonolysis, many of which are carcinogens.

3. No installation of nodes to remove the foam from the surface saniruemogo liquid.

Also known as a "System of water supply of the settlement" (patent RU №2.132.910, CL EV 1/02, 1997, Luk'yanov V.I. and others), containing a pumping station of the second rise, water lines, water supply system, the pressure-regulating capacity, booster, network and wash pumps, carbonator, pressure flotation machine, ozone generator, XLERATOR, two ejector, the first of which is connected with a water pump, carbonator and ozone, the second with a booster pump, pressure flotation machine and chloroform, filter, whose input is connected to the output pressure of the flotation machine and the suction pipe of the flushing pump, and the output is connected with the suction nozzle setev the first pump, pressure gauges, shut-off valves with electromagnetic actuators and position sensors, check valve, safety valve and the control unit, which is associated with the pressure sensors, check valves with electromagnetic actuators and position sensors shut-off valves.

The treated water by means of a booster pump through the first ejector, in which the ozonized air is intensively mixed with water, is fed into the saturator and is compressed. When this occurs, the dissolution of the ozonized air in the water. From the saturator mixture of water and ozonized air with booster pump pressure in the flotation machine from above, and the treated water through the second ejector to the input pressure of the bottom of the flotation cell. Moving towards each other, these streams are intensively mixed, the speed of their movement greatly reduced, ozone interacts with bacterial contamination and released the air in the form of tiny bubbles platinum side contamination. From the pressure of the flotation machine, the treated water is fed to the input of the filter, after which the treated water via the network pump in the water supply to consumers. Upon termination of the water settlement begins filling the treated water pressure-regulating capacity.

For preventive disinfection system water is of locality chlorine. To do this, using a booster pump the treated water is supplied to the pressure input of the second ejector, suction inlet which enters chlorine and mixed thoroughly with water. The mixed flow from the second ejector is fed to the pressure flotation machine, and from there into the filter and then the network pump is directed into the water system for disinfection.

The disadvantages of the known system of water supply of the settlement are:

1. Significant energy consumption through the use of 4 pumps: pumping station of the second lift, booster, leaching and network.

2. The supply of treated water to consumers during the process of regeneration of filter loading.

3. The complexity and unreliability of the regeneration process of the filter loading, carried out by multiple on-off valve with solenoid actuator and the flushing pump, as well as periodic exposure of elastic waves of compression and tension of the liquid in the filter.

4. Inefficient use of ejectors in connection with the fact that they are working with back pressure (for the first ejector connected to the outside bottom part of the flotation cell, the static resistance of a column of water in the flotation cell and dynamic opposition from the outlet of the second ejector and the second ejector connected to the socket isotr the bottom part of the flotation cell, - static resistance of a column of water in the flotation cell, the water column in the filter and dynamic counter with the output of the first ejector). In this case, the effectiveness of the eductor mixers drops significantly.

5. The possibility of secondary bacterial contamination of the pressure-regulating capacity after its completion ozone treated water (given the absence of prolonged action of ozone) and at the termination at this time (e.g. at night) water settlement.

6. The possibility of secondary bacterial contamination of the saturator during the disinfection of the flotation machine, filter and wodorosoda network, because at this time through it stops the supply of ozone treated water.

Closest to the technical essence (prototype) "Installation for water treatment by ozonation" (patent RU №2.228.916, CL C02F 9/04, C02F 1/78, 2004, Patrushev H. and others), containing site water treatment by ozone, made in the form of a cylindrical camera oxidation with lid, provided with a feed pipe of the source water and the pipeline for discharge of treated water, the camera oxidation is equipped with a water level meter that communicates with the device on/off the supply of raw water at achievement respectively lower or upper set of levels, an ejector mounted on camera the oxidation, and a pump connected in series by piping in the recirculation circuit, the ozone generator associated with the ejector, the filter that performs the final stage of water treatment, coupled pump with tubing for discharge of treated water, the block decomposition of residual ozone, connected by pipeline with the camera oxidation, hydrodynamic cavitator type placed inside the chamber oxidation, made in the form of two mounted one above the other with a gap and rigidly connected to each other discs of the same diameter, made in the form of plates, and the upper disk is made of a Central through channel, rigidly connected with the pipeline connecting the camera oxidation with the ejector, and on facing each other, the surfaces of disks made the tabs concentric and narrowing the gap.

The apparatus for water treatment by ozonation of source water is supplied into the chamber oxidation using a circulation pump and ejector, in which the flow accelerates to a high speed, resulting in a fine dispersion of gases and water vapor and saturation of the treated water air and ozone generated in the ozone generator.

Enriched with ozone water in the pipelines of the primary circuit is sent to the cavitator, located in the cell oxidation. Thanks to design the structural features of the cavitator treated water repeatedly expands and contracts, testing mechanical shock and turbulence that provides a high degree of dispersion of water and gas. Thus, due to the increased pressure of the incoming water, multiple expansion-compression when injected into the space between the projections made on the disk cavitator, mechanical shock about them - activated cavitation processes and due to intensification of oxidation of pollutants increases the efficiency of water purification.

Turbulent streams saturated with ozone and oxygen from water with great speed out of the cavitator and connect with the rest of the water located in the lower part of the cell oxidation, providing conditions for intensive mixing of water with ozone-air mixture. The concentrations of oxygen and ozone in the truly dissolved state or in the form of fine bubbles in a colloidal state, reach the highest values. In the cell oxidation is repeated circulation of water, the dispersion of the ozone-air-to-water mixture, actively oxidizing processes. The obtained water-gas mixture repeatedly circulates through the ejector and cavitator, which provides a high removal efficiency for the filter corroded and coagulated contaminants.

As a result, in a single system implemented to becoming the VA ejection dispersion and cavitation, what is achieved by improving the efficiency of water saturation of the air and ozone, and consequently increases the degree of purification of water.

However, the known installation for water treatment by ozonation (prototype) has the following main disadvantages:

1. Increased consumption of ozone and the increase in the total circulation time of the treated water (path: camera oxidation - circulation pump - ejector mixer - cavitator camera oxidation) due to the receipt of the initial water in the camera oxidation without prior mechanical filtration. The total residence time of water in the cell oxidation that is required to oxidize all forms of pollutants, is 20-30 minutes and depends on the chemical composition of the source water, the intensity of the impact of the oxidizing gas mixture is changed by varying the performance of the pump.

2. The possibility of clogging of the circulation pump products of oxidation and coagulation of pollutants contained in the source water, and reduce its service life due to the absence in the cell oxidation node slurry of oxidized contaminants.

3. The poor performance of the unit for re-treatment of sludge and part of the already oxidized and disinfected water left in the bottom of the camera oxidation after its periodic emptying stage is nitelines pump, during the next filling the chamber oxidation of source water.

4. The inefficient use of ozone as a significant portion of the ozone in the camera oxidation above the working level of the treated water (about 50% of its total height), arrives at the destruction in the block decomposition of residual ozone.

5. Inefficient operation of the circulation system due to the fact that within 20-30 minutes is the circulation of the suspension consisting of treated water and oxidation by-products (sludge). This causes additional power consumption for the circulation of the treated water and accelerated wear of the pump.

6. Low sanitary-epidemiological reliability of the processing of source water due to the fact that the time of implementation of the circulation process (achieving the desired effect of cleaning and disinfection of source water) is determined approximately on the basis of previous experience without performing appropriate measurements.

7. The possibility of secondary bacterial contamination filter load during periods of work stoppages additional pump (in the implementation process of circulation), as well as the distribution network due to the lack of prolonged antimicrobial action of ozone.

Thus, the above disadvantages of the known installation is selected as protot the PA, cause insufficient cleaning efficiency of the source water in a changing concentrations of pollutants in it and low sanitary-epidemiological reliability of treatment processes and disinfection of drinking water.

Functionally, the system of water supply of the settlement can be represented in the form of a cylindrical chamber, oxidation, three hydraulic lines and eleven Autonomous devices.

Structurally cylindrical chamber oxidation 1 made in the form of a water tower tank, equipped with nine technological connections:

- water inlet connection 4;

- pipe (pipeline) for discharge of treated water 5;

- suction pipe 9 of the circulation pump 8;

coupling block decomposition of residual ozone 6;

coupling of the respiratory valve 17;

coupling of the level meter redox potential 36;

two nozzles (lower and upper levels) water level meter 2;

- wash nozzle (in the drawing, not the rendered) cylindrical chamber, oxidation 1.

Line pre-treatment of raw water is formed by the auxiliary pump 13, a filter (oxidation-adsorption apparatus) 12, a mode switch 18, the flow sensor 20, the second megasplay ejector mixer 21, a water inlet connection 4 into the cylindrical chamber oxidation 1 and output nozzles 23 of the ring pipe collector 22.

The circulation line formed suction inlet 9, the circulation pump 8, the mode switch 18, the flow sensor 20, the second megasplay ejector mixer 21, a water inlet connection 4 into the cylindrical chamber oxidation 1 and output nozzles 23 of the ring pipe collector 22.

The main thoroughfare of water locality cleansed and disinfected water is formed by a pipeline for discharge of treated water 5 from the cylindrical chamber, the oxidation of 1, the first electromagnetic valve 14, the first megasplay ejector mixer 15 and the distribution of the water network of the settlement.

In addition, the water supply system of the locality is equipped with eleven Autonomous devices, also provides solution to this problem: the ozone generator 11, the ozone generator (filter) 35, disinfectant dispenser 16, the second electromagnetic valve 19, by control valve (electromagn Tim valve filter) 34, block decomposition of residual ozone 6, respiratory valve 17, the water level meter (upper and lower levels) 2, device switching supply source water 3, level meter redox potential 36 and the control unit 37.

The system of water supply of the settlement is as follows.

For the initial filling of the cylindrical chamber 1 oxidation-treated water is used highway preliminary treatment of raw water. The source water is from a natural source 25, such as wells, served an additional pump 13 through its output discharge port 26 to the input of the filter 12 (oxidation-sorption unit), which sequentially processes are carried deep cleaning, conditioning and disinfection of source water:

the treatment of the source water from the trace node microfiltration 27;

intensive mixing of treated water at the site of mixing of ozone from the treated water 28 with an ozone-air mixture produced in the ozone generator 35;

oxidation contained in the treated water pollutants and disinfection in the reaction vessel 29;

- air conditioning (demineralization) of treated water at the site nanofiltration 30;

the sorption of oxidized impurities (p is the FL ozonolysis) sorption node 32.

For the purpose of prevention of emergency situations (the possibility of ingress of water into the ozone generator filter 35) filter 12 is supplied by a pressure sensor 31 and control valve (solenoid valve filter) 34. When the pressure of water passing through the filter 12, the requirements of the operational documentation on the ejector oxidative sorption filters (0.2 to 0.3 MPa) pressure sensor 31 closes its contacts in the circuit of the ozone generator (filter) 35 and a normally closed control valve (solenoid valve filter) 34, the result of which is included in the operation of the ozone generator (filter) 35, opens the control valve (solenoid valve filter) 34 and produced in the ozone generator (filter) 35 ozone-air mixture begins to flow through the opened control valve (solenoid valve filter) 34 on the suction inlet node mixing ozone-air mixture from the treated water 28. When the pressure in the line pre-treatment of source water (e.g., by increasing the hydraulic resistance of the nodes of the filter 12 when the accumulation of filtered contaminants) pressure sensor 31 opens its contacts in the circuit of the ozone generator (filter) 35 and a normally closed control valve (solenoid valve filter) 34, which is enabled from the ozone generator (filter) 35 and closes the control valve (solenoid valve filter) 34.

After making processes microfiltration, conditioning and pre-disinfection in the filter 12 treated water supplied by the auxiliary pump 13 through the mode switch 18 (made for example in the form of two electromagnetic valves with normally-open contact and the normally-closed contact, respectively), the flow sensor 20, the second mehoopany ejector mixer 21, the ring pipe collector (cavitator) 22 and output connections (cavitator) 23 in the cylindrical chamber oxidation 1.

In the second mnogochipovom ejector mixer 21 treated water received his discharge entrance, after intensive mixing with ozone-air mixture in the ejectors mnogoplanovo ejector mixer 21 is supplied under pressure, educated at the output mnogoplanovo ejector mixer 21, through pipe water supply 4 in the ring pipe collector (cavitator) 22 and via output connections (cavitator) 23 is directed to the reflective perforated disc (cavitator) 24, creating a cavitation zone of turbulence, in which there is additional mixing of the water-ozone-air mixture, in a process which involves the oxidation of impurities and effective disinfection of the treated ozone water.

In addition, glenable effective use of ozone method feedback what unreacted in the cylindrical chamber of the oxidation of 1 part of the ozone-air mixture enters through the respiratory valve 17 mounted on the lid of the cylindrical chamber, the oxidation of 1 and its input connected to the internal volume of the cylindrical chamber, the oxidation of 1, the second suction inlet of the second mnogoplanovo ejector mixer 21.

To prevent the possibility of ingress of water into the ozone generator 11 line pre-treatment of raw water is supplied by a flow sensor 20 and the second electromagnetic valve 19. When a continuous flow of treated water through the flow sensor 20 close its contacts in the circuit of the ozone generator 11 and a normally closed second solenoid valve 19, the result of which is included in the operation of the ozone generator 11, opens the second solenoid valve 19 and ozone-air mixture produced in the ozone generator 11 starts to flow through the opened second electromagnetic valve 19 at the first suction inlet of the second mnogoplanovo ejector mixer 21. Upon termination of the flow of treated water through the flow sensor 20 (e.g., by increasing the hydraulic resistance of the nodes of the filter 12 when the accumulation of filtered contaminants) open the contacts of the flow sensor 20 in the circuit GE is erator ozone 11 and a normally closed second solenoid valve 19, bringing off of the operation of the ozone generator 11 and closes the second solenoid valve 19, thereby protecting the ozone generator 11 from flooding the treated water.

After the initial filling of the cylindrical chamber, the oxidation of 1 to the top of the calculated level actuates the upper level sensor (not shown) of the water meter 2, the output of which is applied a corresponding signal to the first input of the switching supply source of water 3. With the first control output switch-off the supply of raw water 3 is supplied with the electric signal at the first control input of the mode switch 18 (made for example in the form of two electromagnetic valves with normally-open contact and the normally-closed contact, respectively), causing actuation of the corresponding solenoid valves, resulting in overlaps highway preliminary treatment of raw water and opens the circulation line. In addition, simultaneously with the second control output switch-off the supply of raw water 3 is supplied with the electric signal to the control input of the auxiliary pump 13 to turn it off, and the third control output switch-off the supply of raw water 3 is given an electrical signal to the control input of the circulating pump 8 for inclusion in the work.

As a result of these switching pre-treated water from the cylindrical chamber, the oxidation of 1 will begin to circulate through the circulation pump 8 through the circulation line formed by the suction nozzle 9, the circulation pump 8, the mode switch 18, the flow sensor 20, the second megasplay ejector mixer 21, a water inlet connection 4, the output nozzles 23 of the ring pipe collector 22 and the cylindrical chamber 1 oxidation. In the circulation process source water circulation line in her sanopoulou through the first suction inlet of the second mnogoplanovo ejector mixer 21 will act ozone-air mixture from the ozone generator 11, and through the second suction inlet of the second mnogoplanovo ejector mixer 21 will flow from the breathing valve 17 unreacted portion of the ozone-air mixture which has accumulated in the ceiling part of the cylindrical chamber, oxidation 1. For emergencies (in case of damage of the respiratory valve 17 or the second mnogoplanovo ejector mixer 21) has a block decomposition of residual ozone 6 is connected by a pipe with a cylindrical camera oxidation 1.

When the circulation of raw water, pretreated in the filter 12, in the cavitation zone of turbulence within tsilindricheskimi oxidation 1 continues additional agitation of the water-ozone-air mixture, in the process which involves the oxidation of impurities and effective disinfection of the treated water with ozone supplied from the ozone generator 11 and the vent valve 17.

The degree of disinfection of the treated water depends on the concentration dissolved in the treated water, ozone, and time of interaction of ozone with pollutants contained in the treated water. Technically much easier to control the time of interaction of ozone with pollutants than to determine the concentration of dissolved ozone treated water. Therefore, regulation of the length of the circulation process is carried out depending on the level of oxidation-reduction potential (redox potential Eh) treated with ozone-air-to-water mixture by using a level meter redox potential 36, structurally placed in the lower inner part of the cylindrical chamber, the oxidation of 1 and generating an information signal about the degree of disinfection of the treated water, and the control unit 37 (device control unit not shown). According to published data, the disinfection of the treated water, as well as the inactivation of bacteria and viruses within it, since Eh=600 mV, which corresponds to the concentration of ozone in water C=0.5 mg/l,and complete sterilization of water occurs when reaching Eh=800 mV, which corresponds to the increase of ozone concentration to a value of 0.7-1.0 mg/l depending on the physico-chemical composition of the treated water.

In the process of consumption is deeply purified and disinfected water from the cylindrical chamber, the oxidation of 1 the water level in it is reduced. Upon reaching a settlement of the lower level is triggered, the lower level sensor (not shown) water level meter 2, giving an appropriate signal to the second input of switch-off the supply of raw water 3. With the first control output switch-off the supply of raw water 3 is supplied with the electric signal at the first control input of the mode switch 18, causing the actuation of the corresponding solenoid valve, which opens the line pre-treatment of raw water. In addition, simultaneously with the second control output switch-off the supply of raw water 3 is supplied with the electric signal to the control input of the auxiliary pump 13 to enable it. Then through line pre-treatment of raw water begins filling the cylindrical chamber, the oxidation of 1 with water cleaned and disinfected in the filter 12. At the same time on the circulation line will be carried out and circulationnitrate source of water in the cylindrical chamber oxidation 1.

Thus, in the pre-treatment of raw water in the filter 12 and the subsequent circulation of the processing in the cylindrical chamber of the oxidation of 1, which is controlled by the level of redox potential, it acquires the properties of purified and disinfected water, suitable for drinking water supply of the settlement.

Given the lack of prolonged disinfectant properties of ozone is used for disinfection of source water, as well as the possibility of secondary bacterial and viral contamination of treated and disinfected water distribution water supply network locality (due to wear of pipelines, power outage, accidents at individual sites and so on), in the proposed system of water supply of the settlement, additional water disinfection in the distribution of the water supply network, which is carried out by introducing into cleansed and disinfected water solution of disinfectant such as sodium hypochlorite.

For this purpose, the first electromagnetic valve 14, the first mehoopany ejector mixer 15 and disinfectant dispenser 16. When reaching into the cylindrical chamber 1 calculated oxidation level of the redox potential of 700 mV, with the second administration is allowing the output control unit 37 is fed to the control input of the normally closed first solenoid valve 14 electrical signal, permitting the supply of the locality of the nozzle for discharge of treated water 5. In this case the electromagnetic valve 14 is opened and the pre-treated and disinfected water to flow from the cylindrical chamber 1 oxidation (water tower) on the pressure input of the first mnogoplanovo ejector mixer 15 and later in distributing the water supply of the settlement. At the height of the water tower is 20 m static pressure in the nozzle for discharge of treated water 5 will be about 2 technology. ATM. At this pressure at the pressure inlet mnogoplanovo ejector mixer 15 at its suction inlet creates negative pressure (vacuum), sufficient to suction disinfectant from the disinfectant dispenser 16 in the working cavity of the first mnogoplanovo ejector mixer 15 where intense stirring of a solution of disinfectant (e.g., sodium hypochlorite) with pre-cleaned and disinfected with ozone water. Design mnogoplanovo ejector mixer that includes multiple nozzles, allows for a design flow of water to conduct an effective mixture of water and disinfectant solution, and to avoid loss of pressure in the eductor-mixer, which is very important in the operation of water towers, with slight pressure (1.5 to 2.0 technology. ATM.)

The materiality of the differences and advantages of the proposed invention causes the following technical solutions:

1. The supply of the main hydraulic line filter 12 (oxidation-Sorb installation of deep purification and disinfection of water), directly connected to the pressure output of the additional pump 13, can improve the sanitary-epidemiological reliability of the entire system of water supply of the settlement, as in the cylindrical chamber oxidation 1 (cumulative capacity of the water tower) is already very clean, air-conditioned and disinfected water, which greatly reduces the possibility of secondary pollution of the treated water after storage in the storage tank water tower (during the time of her evacuation to the calculated level), while in the prototype circulating the processing of the original contaminated water is in the cell oxidation and cavitation for 25-30 minutes, after which the treated water is filtered for sediment filter that periodically undergoes regeneration (leaching). The quality of the water supplied to the distribution network, can vary depending on the degree of contamination of the filter. In addition, when significant contamination of the filter is possible instantaneous release of detainees within filtros the Klah previously oxidized contaminants (e.g., Fe(OH)3- iron hydroxides).

2. Use the level meter oxidation-reduction potential (redox potential Eh) 36 and the control unit 37 allows you to optimize the time the process reactor-bubbling of snoopable and circulation and cavitation oxidation of pollutants and disinfection of source water in the cylindrical chamber oxidation (cumulative capacity of the water tower) 1, ensuring a deep clean and reliable disinfection of source water.

3. The application of the disinfectant dispenser 16, equipped with the first megasplay ejector mixer 15 and the first electromagnetic valve 14 prevents secondary bacterial contamination of treated and disinfected water in the distribution network of the settlement by filing it on the main water supply is required (depending on time of year) the amount of the disinfectant with the properties of prolonged action (e.g., sodium hypochlorite). Structurally, the disinfectant dispenser 16 may be made in the form of series-connected liquid dispenser and storage tanks for solution of disinfectant. The number and order of introduction of the disinfectant by the regulations, developed taking into account the sanitary-epidemiological status is I the distribution network, the design features a cylindrical chamber 1 oxidation, as well as physico-chemical properties of filling its source of water. Given the fact that the distribution network is served already treated and disinfected water, the concentration of the disinfectant can be many times smaller than for disinfection of water in the distribution network. For example, when used in the proposed system of water supply of liquid chlorine is required the dose of injected disinfectant is 0.1 mg/l (in centralized water supply systems the dose of injected chlorine is usually not less than 1.0-1.5 mg/l).

4. Application of method of feedback for the implementation of which is unreacted in the cylindrical chamber of the oxidation of 1 part of the ozone-air mixture from the outlet vent valve 17 is supplied to the second suction inlet of the second mnogoplanovo ejector mixer 21, enables more effective use of ozone generated in the ozone generator 11, as well as reduce the amount of ozone which is subject to decomposition in the block decomposition of residual ozone 6.

5. Application mnogoshipovyh ejectors original design in the second mnogochipovom ejector mixer 21 and the site mixing of ozone from the treated water 28 enables efficient process snoopable, i.e. mixing of ozone-air mixture from the source of the processed water, p is Eva specified bandwidth line pre-treatment of raw water and the circulation line, without causing a significant loss of pressure in them.

6. Accommodation in the circulation line flow sensor 20 and the line pre-treatment of raw water pressure sensor 31, and a second electromagnetic valve 19 and the control valve 34 allows to increase the operational reliability, respectively, of the ozone generator 11 and the ozone generator 35 by preventing the possibility of emergency situations with them.

When the reduction in the circulation line flow rate below a preset value of the flow sensor 20 opens its contact in the power supply circuit of the second electromagnetic valve 19, and the rod of the latter overlaps ozoneproofed connecting the ozone generator 11 with the second ejector mixer 21. Thus, protection of the ozone generator 11 from flooding by water: in moments of connection-disconnection of the filter 12 to the cylindrical chamber oxidation of 1, and increasing the hydraulic resistance in the circulation line due to clogging of the second mnogoplanovo ejector mixer 21.

When the reduction in the line pre-treatment of raw water pressure below a level that ensures the effective operation of ejector mixers, equal to 0.2 MPa, the pressure sensor 31 opens its contact in the circuit of the control valve 34, and the rod p the last term covers ozoneproofed, connecting the ozone generator 35 host-mixing of ozone from the treated water 28. This ensures the protection of the ozone generator 35 from water flooding: in moments of connection-disconnection of the filter 12 to the cylindrical chamber oxidation of 1, and with increasing hydraulic resistance in the line pre-treatment of raw water for the production of resource cartridges node microfiltration 27 and sorption node 32, as well as clogging of the site mixing of ozone from the treated water 28 and the membrane of the host NF 30.

7. The use of the cavitator 7 made in the form of an annular tubular manifold 22, which is located inside the cylindrical chamber, the oxidation of 1 perpendicular to its symmetry axis and fixed on the inner side of the cover cylindrical chamber, the oxidation of 1, a pressure inlet connected to the outlet of the feed pipe water source 4, provided at least three output connections 23, evenly spaced and fixed on the ring pipe collector 22 parallel to the axis of symmetry of the cylindrical chamber, the oxidation of 1, and reflective of the perforated disk 24, which is located perpendicular to the output nozzles 23 of the cavitator 7 and fixed on the inner lateral surface of the cylindrical chamber, the oxidation of 1 at a distance not less than the 2/5 of the height of the cylindrical chamber, the oxidation of 1 from the plane of the ring pipe collector 22, allows to intensify mass transfer processes in a cylindrical chamber 1 oxidation and increase the total time of interaction of ozone-air mixture from the treated water and thereby significantly increase the efficiency of mixing the water-ozone-air mixture, in a process which involves the oxidation of impurities and effective disinfection of the treated water by ozone.

Thus, the use of a complex of the above-mentioned technical solutions can significantly improve the efficiency of oxidation of contaminants and disinfection of the treated water by ozone due to the intensification of processes of interaction of ozone-air mixture from the source water, while also improving sanitary and epidemiological safety of the processes of deep cleaning and disinfection of natural waters, as well as prevent secondary bacterial contamination of treated and disinfected water in the distribution network of the settlement.
