PLANT FOR BIOLOGICAL PURIFICATION OF SEWAGE

摘要

FIELD: effluent purification facilities. SUBSTANCE: this is intended for biological purification purposes and can be used for complete purification of household sewage in small and medium amounts. Plant has primary settler, septictank-stabilizer, biofiltration device, pipelines for delivery of primary sewage and discharge of purified effluent. Primary settler is located above septictank-stabilizer which are interconnected through slot. Biofiltration device is floating in semi-immersed position in primary settler and is connected through pipe to pipeline for discharge of purified effluent which is located below pipeline for delivery of primary sewage. Aforesaid arrangement enhances reliability of plant functioning and improves quality of purified effluent at salvo-like deliveries of sewage. EFFECT: higher efficiency. 1 cl, 2 dwgg
