METHOD OF INTENSIFYING BIOLOGICAL TREATMENT OF WASTE WATER Russian patent published in 2012 - IPC C02F3/02 C02F3/34

Abstract RU 2445275 C2

FIELD: chemistry.

SUBSTANCE: invention relates to biotechnology and particularly to biological treatment of waste water. Waste water is fed into an aeration tank. The sludge mixture and waste water in the aeration tank are aerated with technical-grade air. Melafen is also fed into the aeration tank in amount of 1*10^-4 mg/dm³ - 1*10^-8 mg/dm³. After treatment, the water in a mixture with a sludge suspension is settled. The clarified water is then discharged.

EFFECT: high purification efficiency, improved main characteristics of active sludge, minimisation of operational costs, simple technique and environmental safety.
