Waste water disposal method by continuos inflow Sequencing Bath Reactor and its apparatus

摘要

PURPOSE: A sewage/wastewater treatment system using continuous inflow sequencing bath reactor is provided, which can effectively cope with inflow fluctuation with high nitrogen/phosphorus removal efficiency. CONSTITUTION: Sewage/wastewater of a reservoir(10) is traveled into an anoxic tank(20) continuously, and mixed with sludge recycled from a primary batch reactor(40) in anoxic condition. And sewage/wastewater is treated in a biomembrane reactor(20) packed with fluidized media(33). Finally sewage/wastewater treated in the biomembrane reactor(20) is treated in the primary batch reactor(40). Quantity of recycled sludge is 15 to 30% of quantity of sewage/wastewater introduced into the anoxic tank(20).
