ADVANCED WASTEWATER TREATMENT SYSTEM USING FUSION TYPE

摘要

PURPOSE: A fused wastewater treatment system is provided to extend the lifetime of a separation film and the cleaning period of a separation film in a film-separating process and to remove microorganism secretion materials. CONSTITUTION: A fused wastewater treatment system comprises a bioreactor tank (100); a film separator tank (200); a sedimentation tank (300); and a smart stream (500). The bioreactor tank includes an anaerobic tank (10), an anoxic chamber (20); and an aeration tank (30). The film separator tank removes solid materials by making the treated water flow into the tank and transfers the treated water to a discharge tub. The sedimentation tank degases, deposits, and separates the slurry from the film separator tank and returns sediment sludge. The smart stream make the surplus sludge of the sediment sludge and supernatant flow in, chemically treats the same, and makes treated water with scum removed flow into the bioreactor tank.
