UNIT FOR THE TREATMENT OF WASTE, DRAINAGE, BOREHOLE, POND WATER OF CIVIL AND INDUSTRIAL FACILITIES Russian patent published in 2023 - IPC C02F9/00 C02F1/78 C02F1/461 

FIELD: environmental protection.

SUBSTANCE: invention can be used to treat waste, drainage, borehole and pond waters comprising complex hardly oxidizable organic impurities, up to water quality standards for fishery water bodies, up to technical circulating water standards, for discharge into centralized sewer systems, as well as to the TLV level for drinking water. The unit comprises sequentially installed electrolysis and ozonation tanks and cascade filters for final cleaning. In front of the electrolysis tanks, an ejector for supplying ozone is installed, connected to a receiving balancing tank with a sprayer and an aerator. The tanks are cascaded with a working surface difference of at least 0.4 m to each subsequent tank. The ozonation tank is made in the form of a secondary ozonation tank with a cavitator. Between the secondary ozonation tank with a cavitator and the outlet tanks of the cascade filters for final cleaning, a water ozonizer with its own pump is installed in the OH-radical loop. Inverter electrolyzers are used in electrolysis tanks.

EFFECT: increased degree of purification of polluted waters, simplification and reliability of the design.
