<p>A wastewater treatment apparatus is provided to reduce an operating cost, be completely sealed to reduce the generation of odor, and minimize structure facilities, machinery and equipment by using waste styrene foam as microorganism media and effectively connecting a precipitating process, a filtering process, an activated sludge process, a trickling filter process and a contact oxidation process. An apparatus for treatment of wastewater using waste styrene foam comprises: an air pump tank(25) for pumping compressed air and inflow water by operating a valve; a first diffusing and aerating tank(6) for diffusing the compressed inflow water and air through a lower part of the air pump tank; a first trickling filter reactor(7) having a distributor(9) installed on an upper part thereof to distribute the compressed inflow water and air of the first diffusing and aerating tank; a second diffusing and aerating tank(10) into which the compressed inflow water and air of the first trickling filter reactor are diffused through a lower part of the second diffusing and aerating tank; a second trickling filter reactor(12) having a distributor(22) installed on an upper part thereof to distribute the compressed inflow water and air of the second diffusing and aerating tank; and a final sedimentation tank(15) having an air exhaust port which is formed on a lower part thereof, and through which the compressed air of the second trickling filter reactor is released, and a discharge port formed on an upper part thereof to discharge the inflow water into a natural atmospheric pressure.</p> |
