METHOD FOR WASTEWATER PURIFICATION FROM AMMONIUM AND ORGANIC MATERIAL AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC C02F3/34 C02F3/30 C12M1/02 C12M1/04 C12N1/20 

FIELD: biotechnology.

SUBSTANCE: method and a plant for wastewater purification from ammonium and organic substance under microaerobic conditions are proposed. The purification process includes autotrophic and heterotrophic denitrification with free-floating flocculated silt and silt fixed on a stationary charge in the reactor, silt grinding, re-settling, phases separation with removal of purified water and returning of the compacted silt to the bioreactor. Active silt contains anamox bacteria. The waste water purification plant includes a filter with a grid, a settling tank, a primary settler, a heat exchanger, a bioreactor with a blade agitator and a stationary sheet feeder, a post-oxidation reactor with an air supply, a flow mill, a secondary settler connected to a bioreactor, all interconnected by pipes.

EFFECT: improved wastewater purification efficiency.
