METHOD FOR PURIFICATION OF MULTICOMPONENT WASTE WATER Russian patent published in 2021 - IPC C02F9/06 C02F11/15 

FIELD: treatment of water.

SUBSTANCE: invention relates to the field of environmental protection, particularly, to purification of multicomponent waste water, and can be used as small and medium local purification facilities with a productive capacity of 1 to 10 m³/h for the tobacco industry. The invention relates to a method for purification of multicomponent waste water in the tobacco industry, including supplying the polluted liquid into a storage reservoir, pneumatically mixing, removing the suspended substances in a vertical settling vat, adding sodium chloride and simultaneously mixing in a pneumatic mixer, executing deep electrooxidative sorption purification and supplying the purified water into the storage reservoir. The electrooxidative sorption purification is executed in an electrolyser-adsorber apparatus, and a granular composite sorbent based on tobacco raw material waste and bentonite clay is used as a sorption material.

EFFECT: increased level of purification of multicomponent waste water due to reduced content of organic substances and mechanical impurities in the purified waste water.
