Abstract:
A submerged type membrane separation advanced treatment system is provided to remove suspended materials, organic contaminants(BOD,COD) and nitrogen and phosphorus existing within foul water with high efficiency. A submerged type membrane separation advanced treatment system comprises a flow control bath(50), an aeration tank(10), an anoxic chamber(20), a membrane separation aeration tank(30), a separation film(80) and a suction pump(90). The flow control bath removes adulteration from the foul water flown in and supplies the foul water of predetermined amount. The aeration tank receives the foul water from the flow control bath. Dissolved organic matters existing in the foul water are disassembled by aerobic microorganism in the aeration tank. The anoxic chamber receives a mixed solution of microorganism and the foul water from the aeration tank. The membrane separation aeration tank receives the mixed solution of microorganism and the foul water from the anoxic chamber.
Abstract:
A method of treating wastewater which comprises the flow-in step of flowing organic wastewater into an active sludge tank having an active sludge containing microorganisms pooled therein and the separation step of biologically treating the organic wastewater in the active sludge tank and then subjecting the thus treated liquor to solid/liquid separation with the use of a separation membrane device located in the active sludge tank, characterized in that the sugar concentration in the aqueous phase of the active sludge is maintained within a definite range during the separation step. According to this method, the risk of reducing the effective membrane area due to sticking of biopolymers to the membrane surface can be appropriately evaluated and thus the wastewater can be efficiently treated while preventing an increase in membrane filtration resistance.
