PURPOSE: A sewage purification treatment system is provided to remarkably improve purification efficiency, to improve the durability of a backwashing filter, and to remarkably increase purification efficiency. CONSTITUTION: A sewage purification treatment system comprises a purifier(100), a hollow fiber membrane filtering apparatus(200), a backwashing storage tank(300), a filtering apparatus(400), a pump(500), and a controller. The purifier is divided into an inflow bath(110), an aeration tank(120), an anoxic chamber(130), and a discharge tank(140). The hollow fiber membrane filtering apparatus has a plurality of hollow membrane pipes. The backwashing storage tank is installed in the outer side of the purifier and selectively stores the treated water for backwashing the hollow fiber membrane filtering apparatus. The filtering apparatus filters the treated water and discharge the final treated water. The pump transfers the water to the hollow fiber membrane filtering apparatus. The controller controls the backwashing treatment of the hollow fiber membrane filtering apparatus. |
