<p>PURPOSE: Provided are a wastewater treatment apparatus with a bioreactor having non-woven fabric filter and a wastewater treatment method using the same apparatus. CONSTITUTION: The apparatus comprises a bioreactor(100) with a wastewater inlet and an air vent at an upper portion thereof, and a treated water outlet at the bottom thereof, and a non-woven fabric filter bag(101) installed in the bioreactor(100) in such a way that the filter bag is separated from inner side surfaces of the bioreactor(100), wherein the filter bag(101) has an opening at an upper portion thereof and a closed lower end, and an air diffuser(102) provided at a lower portion of the filter bag(101) for aeration in the bioreactor(100). The method comprises the steps of inputting solution mixture containing microorganism into the bioreactor with the non-woven fabric filter bag therein, culturing the microorganism while supplying air to the bioreactor, inputting wastewater at a constant flow rate, and removing nitrogen and phosphorous in the wastewater by microorganism under aerobic or anaerobic condition.</p> |
