Description

 The invention relates to installations for electrochemical water treatment and can be used in various fields for the purification and disinfection of water.

 Known installations for electrochemical water treatment of various designs (US Pat. RF N 2084408, CL C 02 F 1/461, 1997, US Pat. RF N 2091320, CL C 02 F 1/461, 1997).

 But when treating water in known installations, the degree of disinfection and purification of water is insufficient.

 The closest device of the same purpose to the claimed invention, in terms of features, is an installation for the electrochemical treatment of drinking water, containing at least two cylindrical, vertical, electrochemical cells, with coaxial electrodes, of insoluble material during electrolysis, installed in dielectric bushings with a diaphragm of ceramics coaxially installed in the bushings between the electrodes and dividing the interelectrode space into the anode and cathode chambers with inputs in the lower and conclusions in the upper parts of the chambers, a container with a catalyst, a swirl and flotation chamber. (Pat. RF N 2096337, class C 02 F 1/46, 1997).

 A disadvantage of the known solution is the low degree of disinfection and water purification.

 The invention consists in the following.

 The problem to which the invention is directed is to improve the degree of disinfection and purification of drinking water, if possible bring it closer to the taste of spring water, increase the biological value.

 EFFECT: preliminary cleaning of metal ions, additional oxidation and its final reduction in the cathode chamber, complete disinfection of the initial water in the anode chambers.

 The specified technical result during the implementation of the invention is achieved by the fact that in the device is an installation for the electrochemical treatment of drinking water containing at least two cylindrical vertical electrochemical cells with coaxial electrodes of insoluble material during electrolysis, mounted in step holders with a ceramic diaphragm, coaxially installed between electrodes and dividing the interelectrode space into the anode and cathode chambers with inputs in the lower and terminals in the upper parts to amer, while in the inventive installation, the input line of the purified water is connected to the inputs of the anode and cathode chambers of the first cell, the output from the anode chamber of the first cell is connected to the input of the anode chamber of the second cell and then with the input of the second cell into the cathode and the output of purified water, and the output from the cathode chamber of the first cell with a drain, the installation is equipped with a vortex chamber mounted on the input line into the cathode chamber of the second cell, on which a catalyst container is also installed after the vortex chamber.

 Installation for water treatment is shown schematically in the drawing.

 The installation comprises a first electrochemical cell 1, a second electrochemical cell 2, a vortex chamber 3, a container for a catalyst 4, a tee 5, a supply line of treated water 6, a drainage drain 7, a outlet of purified water 8.

 Installation works as follows.

 The treated stream of water 6 from the pressure source, through the tee 5 enters the electrochemical cell 1 in the anode and cathode chambers. In the anode chamber, organic impurities (phenols, formaldehydes, etc.) are oxidized and active chlorine is formed from salts that make up the natural mineralization of water, which destroys microorganisms. In the cathode chamber, metal ions are deposited and directed to drain 7. Next, the flow from the anode chamber of cell 1 enters the anode chamber of cell 2, where organic impurities are oxidized and water is disinfected, oxygen and ozone are saturated. After further oxidation, water enters the vortex chamber, where the process of water disinfection continues, and then to the catalyst chamber 4. After this, the water flow passes through the cathode chamber of cell 2 for direct electrolytic and homogeneous reduction, while the biological value of water increases. From the cathode chamber, pure water goes to exit 8.

 Thus, the claimed invention - the installation for electrochemical water purification has increased efficiency of electrochemical reactions, is simple in design, while the degree of disinfection and purification of water is increased.
