METHOD FOR PROCESSING FAECAL AND LIVESTOCK WASTE Russian patent published in 2019 - IPC C05F11/08 C02F3/32 C02F11/02 C02F103/20 

FIELD: biotechnology.

SUBSTANCE: invention relates to biotechnology and can be used at poultry farms, livestock farms and complexes. Method of processing faecal and livestock wastes involves spraying effluents with a concentrated soil solution, filling a gravitational separation column and maintaining a time interval sufficient for separation into a liquid fraction and a precipitate. Liquid fraction is poured into a swimming pool populated with waterfowl vegetation, kept there till the vegetation is filled with 90–95 % of the pool mirror with further removal of excess vegetation from the pool, leaving about 20 % of the basin mirror area. Drained effluents are drained from the basin, and sediment is unloaded and processed into eco-chernozem and concentrated soil solution, part of which is supplied for sprinkling of the next portion of effluents, after which a cycle of this portion is processed. At that, after drainage of one gravitational separating column by drains, flow of wastes is switched to another gravitational separation column, and duckweed is used as waterfowl vegetation.

EFFECT: invention enables to obtain wasteless waste processing technology, obtain eco-chernozem and improve environmental conditions.
