METHOD FOR ELECTROCOAGULATION PURIFICATION OF DRINKING AND WASTE WATER Russian patent published in 2021 - IPC C02F9/02 C02F9/12 

FIELD: water treatment.

SUBSTANCE: invention relates to the field of technology of electrocoagulation purification of water from natural underground and surface water sources with a predominantly high concentration of mineral and organic pollutants and pathogenic microflora of both natural and technical origin, due to the discharge of untreated wastewater into reservoirs and the precipitation of toxic substances with atmospheric precipitation in conditions of non-alternative use of existing water sources with a high content of pollutants. The method for electrocoagulation treatment of natural water and wastewater of various origins includes four-stage blocks of galvanoinductive treatment of the first and second stages, a four-stage block of electrocoagulation treatment, a high-frequency electromagnetic treatment system, a block of electromagnetic treatment with perpendicular fields, a block of flotation treatment with gas separation, chambers of a suspended layer of deep sorption treatment, chambers of stepwise thin-layer sedimentation, a filter with floating polymer loading, a power supply and control unit, the power supply unit of the high-frequency electromagnetic processing system and the dosing unit of the correction solution. Water is treated four times in the four-stage galvanoinductive treatment unit of the first stage and treated four times in the four-stage galvanoinductive treatment unit of the second stage, while water is simultaneously treated with galvanoinductive and electrocoagulation treatment in an electromagnetic field with a frequency of 25-135 kHz, followed by its treatment in electromagnetic fields perpendicular to each other.

EFFECT: achievement of guaranteed and stable provision of normative indicators of the quality of drinking water treatment in accordance with the requirements of the Sanitary Regulations and Norms and the quality of treated wastewater in accordance with the discharge standards, while achieving high water purification indicators in a short period of time.
