摘要
PURPOSE: A submerged membrane coupled activated sludge system using intermittent aeration for simultaneous removal of nitrogen and phosphorus is provided. CONSTITUTION: The operation of anoxic process includes inflow of sewage/wastewater into an anoxic/anaerobic tank(2) continuously; recycling wastewater of an aeration tank(5) into the anoxic/anaerobic tank for anoxic condition; denitrification of recycled nitrite using organics of raw sewage/wastewater as carbon source; nitrification and organics decomposition in the aeration tank; and discharging treated water by the submerged membrane(6). Also, the operation of anaerobic process includes inflow of sewage/wastewater into the anoxic/anaerobic tank continuously; stop recycling wastewater of an aeration tank into the anoxic/anaerobic tank for anaerobic condition; phosphorus release using organics of raw sewage/wastewater as carbon source; phosphorus luxury uptake and nitrification in the aeration tank; discharging treated water by the submerged membrane; and discharging sludge for removing phosphorus.
