Abstract: To provide an apparatus and a method for treating wastewater, which are efficiently remove organic matters and nutrients at the same time from domestic wastewater. The apparatus comprises a first settling tank and a flow equalization tank (2) which is able to remove firstly precipitates from domestic wastewater, a first anoxic tank (3) which denitrifies nitrate nitrogen contained in sludge returned from the final settling tank using organic matters in the wastewater flown-in from the first settling tank and equalization tank, a second anoxic tank (4) which denitrifies nitrite nitrogen and nitrate nitrogen contained in the sludge flown-in from the first anoxic tank and returned from a contact aeration tank (6), an activation sludge tank (5) which oxidizes organic matters contained in the sludge flown-in from the second anoxic tank and nitrifies ammonia nitrogen into nitrite nitrogen and nitrate nitrogen, the contact aeration tank which maximumly extends residence time of microorganism using adhesive filter media (15), secondarily oxidizes non-treated organic matters contained in the sludge flown-in from the activated sludge tank and oxidizes the ammonia nitrogen into the nitrite nitrogen and the nitrate nitrogen, a final settling tank (7) which divides the sludge flown-in from the contact aeration tank into solid materials and treated water and then finally discharge them, and a microorganism activation tank (8) which includes microorganism materials that are cultivated from specific soil microorganisms and activates dominant species of the sludge returned from the final settling tank.

Abstract: PURPOSE: Provided is a system for removing nutrients of domestic sewage using two step aeration which can remove organic matters in wastewater efficiently by activated sludge process and contact aeration process, and can remove nutrients such as nitrogen and phosphorus by installing denitrification chamber and dephosphorization chamber. CONSTITUTION: The system comprises a flow equalization basin(2) which equalizes flow rate and concentration of wastewater and primarily settles grits; a denitrification tank(3) which reduces NO3-N to nitrogen gas in denitrification tank; an activated sludge tank(4) which nitrifies organic matters and NH3-N in aerobic condition; an intermediate settling tank(5) which separates activated microorganism sludge and disposed water; a contact aeration tank(6) which is packaged with contact media(13) to extend retention time of microorganisms; a dephosphorization tank(8) in which phosphorus is released in anaerobic condition; a chemical precipitation tank(9) in which phosphorus is precipitated by using coagulants; a final settling tank(7) which separates sludge and treated clean supernatant water.
