PROCESS OF WATER PURIFICATION AND DISINFECTION Russian patent published in 2003 - IPC

FIELD: electrochemical method of purification and disinfection of sewage, industrial and other water, especially contaminated by ions of heavy metals, other inorganic and organic harmful substances. SUBSTANCE: invention can find use at factories of non-ferrous metallurgy, chemical industry, radio electronics, mechanical engineering and other branches of technology. Process of water purification and disinfection includes treatment of water with ozone-carrying gas with imposition of electric field and ultraviolet radiation. Water is treated with ozone-carrying gas by mixing till mixture with concentration of ozone from 6 to 15 mg/l is obtained, electric field is formed by transmission of electric current with density from 0.01 to 0.025 A/sq cm through obtained mixture. Ultraviolet source which power lies between 100.0 and 200.0 W is used. Obtained water mixture is treated by imposition of electric field and ultraviolet radiation in the course of over 5 min. EFFECT: raised degree of purification of water from metals and organic compounds. 1 cl, 2 tbl
