METHOD OF PURIFICATION OF THE WATER FROM THE HARMFUL IMPURITIES AND THE INSTALLATION FOR THE METHOD REALIZATION Russian patent published in 2008 - IPC C02F9/06 C02F1/463 C02F1/78 

FIELD: different branches of the national economy; methods and the devices for purification of the water from the harmful impurities.

SUBSTANCE: the invention is pertaining to the method and the installation for purification of the water from the harmful impurities. The method of purification of the water provides for the water aeration by the water feeding in the jet device for aeration mixing with the air. At that the aeration is conducted in two stages: at the first stage the aeration is conducted by commixing of the being purified water with the air or the air treated in the ozone installation with the air containing from 5 up to 40 % of ozone, then the produced mixture is gated through the swirler of the flow intensifying the process of the dissolution of the air or the air-ozone mixture in the water. Then conduct the second stage of the water treatment with the air or the air-ozone mixture with production of the water with рН from 9 up to 9.5. The produced aerated water is fed into the electrocoagulator, where conduct its electrochemical treatment with coagulation of the impurities and production of the outlet water with pH from 9.5 up to 10. After that they conduct clarification and ozonization of the water with its simultaneous treatment with the vapors of the nitric acid with recuperation of pH of the water up to 6.5 - 7. After that they conduct the water purification in the system of the ponds. The installation of the water purification contains the jet device for the water aeration, which outlet is connected to the flow swirler, which in turn is connected to the second jet apparatus for the water aeration. The latter outlet is connected to the electrocoagulator. The electrocoagulator is connected to the system of the water clarification, which outlet is connected to the jet apparatus for the water ozonization, which is supplied from the side of its air inlet with the ozonizing apparatus and the outlet of the jet apparatus is linked with the system of the ponds. The technical result of the invention is reduction of the prime cost of the water purification and the increased reliability of operation of the water purification installation.

EFFECT: the invention ensures the reduced prime cost of the water purification, the increased reliability of operation of the water purification installation.
