FIELD: biological cleaning of sewage in fluidized bed. SUBSTANCE: proposed plant includes biological cleaning section located after first settler which is partially filled with particles of culture media with seeding surface of no less than 800 sq.m per cu.m of bulk volume. Provision is made for retaining device which holds particles of culture media; secondary settler is located vertically behind this device. Biological cleaning section is additionally provided with non-aerated section of biofilters filled with particles of culture media which receive flow from primary settler and return flow of slurry from secondary settler. EFFECT: enhanced reliability avoidance of rotting and choking. 4 cl, 4 dwg
