METHOD OF INTEGRATED MUNICIPAL SEWAGE WATER TREATMENT AND SEDIMENT REWORKING IN VILLAGES WITHUNSEWERED AREAS Russian patent published in 2017 - IPC C02F9/14 

FIELD: chemistry.

SUBSTANCE: method of integrated municipal sewage water treatment comprises equalization of consumption to hourly average consumption, mechanical sewage water treatment in sediment tanks, biological treatment in multistage bioreactors using biocenoses - microorganisms attached to the fiber brush nozzle, advanced sewage water treatment in the aerobic bioreactors and processing of precipitations excreted during sewage water treatment. Sedimentation is performed in the clarifier with flocculation chamber with natural aeration, precipitations of sewage water are fed from the clarifiers into anaerobic digester with a temperature of 15°C, while biological treatment is performed in nitri-denitrification bioreactors with biocenoses attached to the brush nozzle of polyamide super slim fibers with recirculation of treated water from the second nitrification stage to the denitrification stage, reclaimed water from the nitri-denitrification and advanced treatment bioreactors is fed into the consumptrion equalizing tank with supernatant water of digesters.

EFFECT: quaility improvement of the water treatment, process simplification.
