METHOD AND DEVICE FOR ELECTROCHEMICAL INDUSTRIAL WASTE WATER AND DRINKING WATER TREATMENT Russian patent published in 2017 - IPC C02F9/00 C02F1/00 C02F1/28 C02F1/32 C02F1/36 C02F1/463 C02F1/465 C02F1/467 C02F1/52 C02F1/78 B01D21/00 

FIELD: chemistry.

SUBSTANCE: after the preparatory phase gravity settling follows the main processing consisting of electrocoagulation electrooxidation and electroflotation by the action of metal sets of electrodes made of stainless steel, and aluminium, respectively, with simultaneous disinfection/oxidation by ozone, UV radiation and sonication, and recycling in the electromagnetic field. At the end of the main processing a mixture of water and subjected to flocculation coagulation/flocculation under the influence of electrochemically formed from steel and aluminium flocculation with a slow introduction of ozone. The next phase is the separation of sludge from pure water which is discharged into a collecting container through a sand filter and an activated carbon filter to remove light floating flocs. If necessary, water is oxidized under the simultaneous action of UV radiation and ozone for final degradation of organic matter and ammonia, and possible residues of microbiological contamination.

EFFECT: invention provides an apparatus for treatment of industrial waste water, in which the electrochemical processes are used.
