Summary description： The design daily treatment capacity of wastewater treatment in jinguolin villa area is 300 tons. The pwt-a-300 type equipment independently developed and produced by Huayu brilliant is adopted. The anoxic + aerobic + MBR process is adopted to solve the sewage discharge problem of 1500 people in the villa area, so as to avoid the direct discharge of sewage into the jiakuo River and cause environmental pollution.
