The invention relates to a device for water treatment, in particular to installations for water treatment nome and land transport, the objects of their security, as well as in swimming pools, in the production of alcoholic and non-alcoholic beverages and in other areas of the economy.

Known water treatment plant silver ions containing the cell with silver electrodes, the power supply cell constant current source with a switch in the polarity of the electrodes and a piping system for supplying and draining water. (See French patent N 2057332, IPC 6 C 02 In 1/00, 1971 ) the Disadvantage is the inability to maintain a constant concentration of silver ions in the treated water when changing the flow of water, its salinity and the polarization of the electrodes. Also known installation for water treatment with silver ions, which to a certain extent eliminated the above-mentioned drawback. This setting is the closest to the essential features analogue (prototype) to declare. (See description of the invention to author's certificate N 629727, IPC 6 C 02 F 1/46, 1993). Known installation-the prototype for water treatment with silver ions includes the electrolyzer with silver electrodes, the power supply cell constant current source with a switch in the polarity of the electrodes and systemgenuine with stabilized output a constant current source. But installing the prototype does not allow full and more effective disinfection of water from various sources, including from open water bodies (rivers, lakes).

The challenge faced by the developer was to create an installation for the treatment of water with silver ions, which would allow for the complete disinfection of water from various sources, including from open water bodies (rivers, lakes). The technical result achieved when the solution before the inventor of the tasks was the possibility of additional clean disinfected water, as well as more effective disinfection. This additional purification consists in the following. The presence of Halogens in the treated water in the storage tank, as well as sulphate and other impurities, active silver, leads to a chemical reaction, which produces a certain amount of insoluble or poorly soluble compounds, for example, AgCl precipitated. As a result, water is additionally cleaned of contaminants, and silver-containing precipitate, mainly AgCl, long-term supports bactericidal effect processing. However, there is a clearing of water from excess silver is "drinking Water" maximum allowable concentration (MAC), and from the cells died in the disinfection of microorganisms. And the effectiveness of disinfection increases by 30...40% due to the fact that the disinfected water before entering the discharge pipe is kept in a cumulative capacity of not less than 60 minutes. Such exposure is enough to destroy 10⁷CL/DM³E. Coli bacteria at a concentration of silver ions in 2... 3 times lower than in the installation of the prototype. The essence of the invention lies in the fact that the water treatment plant silver ions that includes an electrolytic cell with silver electrodes, the power supply cell constant current source with a switch in the polarity of the electrodes, the sensor volume flow of water, coupled with stabilized output a constant current source, and a piping system for supplying and draining the water, it also contains the cumulative capacity installed on the outlet piping system, behind which is mounted a filter additional chemical and biological treatment. However, the essence of the invention lies in the fact that the installation further comprises a second cell that is interlocked with the first, and in that the cell contains a block of paired electrodes.

The water treatment plant silver ions includes the electrolyzer 1. The electrolytic cell 1 consists of a metal casing 2 in which is placed a silver electrodes 3 attached to the cover 4. To ensure complete filling of the cell treated water inlet pipe 5 has a diameter greater than the diameter of the outlet pipe 6. Depending on the performance of the installation, i.e., the volumetric flow rate of treated water, the ratio of the diameters of the inlet and outlet pipes varies between 1,0 0,3.... To establish the optimal volumetric flow rate of treated water through the electrolyzer serve as the valve 7 and the flow meter 8. The constant current source 9 is connected with a silver electrode 3 through electronic polarity reversing switch 10, the automatic current regulator electrolysis 11 and the switch 12. At the beginning of the piping system 13 is mounted pump 14, and then during the coarse filter 15 and the filter 16. As filters for coarse and fine cleaning can be applied any filters that provide the necessary degree of purification of water from open water bodies, such as the MPC according to GOST 2874-82 or optionally above. This can be ion-selective filter, various stations slim PTS from chemical and biological impurities 18. The piping system 13 after additional purification filter 18 is connected to the water supply system 19. To automatically maintain the required water level in the storage tank 17 is a device multistage regulation 20, which is functionally connected with the pump 14 and system level sensors 21. The compensator 22, controlled by the sensors 23, 24, and 25, is designed to eliminate the influence on the process of electrolysis such important parameters as pH, temperature, salt content of the water, and the degree of dissolution of the silver electrodes. In addition, the compensator 22 is functionally associated with audio 26 and light 27 signals. The timer 28, which is connected with the electronic polarity reversal switch 10 serves to regulate the duration of the cycle of polarity electrode current to compensate for their polarization. Depending on the conditions of the electrolysis, the change of polarity electrode current can be set with frequency 0...30 minutes For direct control of the actual concentration of silver ions in the treated water and control the process of electrolysis is ion meter-corrector 29, controlled ion-selective silver ion probe 30 included in the piping system 13. In the pipe system cm is also the second cell 32, which is interlocked with the first electrolytic cell 1. The cell 32 as well as the first consists of a metal casing 33 in which is placed a silver electrodes 34, secured to the cover 35. The cell 32 has an input 36 and output nozzles 37. Each input connection of the cells 1 and 32 are equipped with electronic valves water supply 38 and 39. And in each output connection of the cells 1 and 32 valves 40 and 41. The inventive installation also includes a control unit 42 and an associated pressure sensor water 43.

Works of the inventive installation for water treatment with silver ions as follows. Treated water through pipes 13 by pump 14 serves on the coarse filter 15, and then on the fine filter 16. Then the water pipeline through the electromagnetic valve 38 or 39 is supplied to the electrolyzer 1 or 32. In one of the cells, the water is saturated with silver ions through the electrolytic dissolution of silver electrodes 3 or 34, which serves a constant electric current from the switch 12. Saturated with silver ions water from cell 1 or 32 through the check valve 40 or 41 is supplied to the flow meter 8 where the holding tank 17. From the storage tank 17 is supply 19, In the accumulation tank 17 disinfected water automatically by the device multistage regulation 20 is supported within 0,7...0,8 from its height. In the accumulation tank 17 the water is full decontamination guaranteed the necessary concentration of silver ions and exposure. The presence of Halogens in the treated water, as well as sulphate and other impurities, active silver, leads to a chemical reaction, which produces some amount of insoluble and soluble compounds, such as AgCl precipitated. As a result, water is additionally cleaned of contaminants, and silver-containing precipitate, mainly AgCl, long-term supports bactericidal effect processing. Filter further purification of chemical and biological impurities 18 also purifies the water from rain and excessive silver, bringing the concentration of its ions to the level of the MPC, i.e. not higher than 0.05 mg/DM³and from cells killed in the disinfection of microorganisms. In the process, the particles of the carbon filter covered with silver, which, in turn, prevents secondary bacterial growth. Adsorbing organic impurities, this filter improves taste and smell of drinking water. In the AMI silver constant current source 9 is turned off by the control unit 42 by the signal of the pressure sensor water 43. The same disconnection may occur on the signal ionomer-corrector 29 emergency mode electrolysis process. To improve the reliability of plant operation and continuity of the electrolysis process when replacing worn-out electrodes has a second cell 32, the same as the electrolyzer 1. When reaching the wear silver electrodes 3, constituting 90% of their mass, the compensator 22 sends a signal to the switch 12, and 26 includes sound and light 27 signals. Audio 26 and light 27 signals included in the absence of current to the electrodes of electrolytic cells, i.e., when the breakage of the electric circuit or a short circuit in the circuit of the electrodes. Upon receipt of the signal from compensator 22, the switch 12 closes the solenoid valve in the water supply 38, disables the flow of current to the electrodes 3, i.e., disables the electrolytic cell 1, and simultaneously opens the solenoid valve in the water supply 39 and supplies current to the electrodes 34, i.e., includes the cell 32. Check valves 40 and 41 eliminate mutual influence flows through the electrolytic cells 1 and 32. The presence in the plant of the compensator 22, controlled by sensors 23, 24 and 25, and the automatic current regulator 11 is almost completely provide stability concentrational to obtain a predetermined concentration of silver ions by indirect method. The presence of ionomer-corrector 29 and an ion-selective sensor 30 allows you to manage the process of electrolysis, depending on the actual concentration of silver ions in the treated water by direct measurement. The presence of these two control systems makes it possible to continuously treat the water in case of failure of one of them.

Thus, the claimed setting allows the full and more effective disinfection of water from various sources, including from open water bodies (rivers, lakes). In addition, it has increased the reliability and accuracy of dosing silver, high efficiency of the flow of the precious metal. It allows continuous processing of water in emergency situations and when replacing worn-out electrodes. Schematic solution allows to obtain with high accuracy given the concentration of silver ions in the treated water when changes such important parameters, source water contamination, pH, temperature, chloride content, sulphate ions Br^-I , J^-, CO^2-₅and when other changes in the salt content, causing a change in conductivity of the water and the passivation of the electrodes, when they wear up to 90% of their mass.
