SEWAGE BIOLOGICCAL PURIFICATION METHOD Russian patent published in 2005 - IPC

FIELD: municipal economy; industrial enterprises; sewage purification.

SUBSTANCE: the invention is pertaining to the methods of biological purification of sewage in bioreactors and may be used in the water drain systems of municipal economies and the industrial enterprises at purification of sewage. The sewage is treated in a bioreactor with membranous separation of water and an active sludge. Conduct a periodic regeneration of the separator. The membrane contains oxidation catalysts in the form of a combination of metals with variable valence, for example - manganese or cobalt oxides. The technical effect is intensification of processes of a biological purification of sewage, an increase of duration of a filtration service life of the membranous separator and reliability of its operation.

EFFECT: the invention ensures intensification of processes of the biological purification of sewage, increased duration of a filtration service life of the membranous separator and reliability of its operation.
