BIOREACTOR FOR THREE-SILT SYSTEM OF PURIFICATION OF SEWAGE Russian patent published in 2005 - IPC

FIELD: devices for biological purification of sewage.

SUBSTANCE: the invention is pertaining to devices for biological purification of urban and similar by composition industrial sewage and may be used in a municipal services and at industrial enterprises. The first silt system of the bioreactor is based on usage of a fixed on the rigid barbed head bacterial cenosis of heterotrophic microorganisms in the bays of the ideal mixers with a number of the rigid barbed nailheads ensuring conformity of capabilities of the oxidizing power of the aerating system with the oxidizing power of the biomass of the adnate micro-organisms. Withdrawal of the excessive biomasses of the silts from the second and third silt systems is arranged due to a device located in the bay of the third silt system of the chamber partitioned by a solid vertical partition, and supplied with a thin-layered silt separator, a pipeline for removal of the dense silt for dehydration and a launder for withdrawal of the above the silt water to the inlet of the purified sewage in the first bay of the third silt system. The passage way of the bioreactor of the third silt system is divided by the solid vertical partitions into the chambers filled with containers with barbed nailhead supplied with the separately operating systems of bubblers of water aeration and regeneration checker-works. The technical result is an increased efficiency and stability of work of the first silt system with simultaneous simplification of its operation and a decreased consumption of materials, putting a discharge, silt separation and withdrawal of the above silt water in good order at withdrawal of the excessive sediments from the silt system.

EFFECT: the invention ensures an increased efficiency and stability of work of the first silt system with simultaneous simplification of its operation and a decreased consumption of materials.
