- 摘要：
PURPOSE: To increase purification efficiency of wastewater by using a multi-stage biological membrane and minimize equipments by a layered structure of the biological membrane. CONSTITUTION: The apparatus comprises a wastewater reservoir(15) installed to collect wastewater, a biological membrane reaction tank(13) where many first and second biological membrane contact tanks(2,3) are selectively installed on the inner side of a hopper(4) vertically and horizontally, a settling tank(9) installed to settle foreign materials in the first treated water at the wastewater reservoir and the hopper and a wastewater circulation part(11) installed to recirculate supernatant of the settling tank and the wastewater reservoir to the biological membrane reaction tank. The feed is prepared by hydrophilizing byproducts treated by the wastewater treatment apparatus.
