Abstract

The biological purification device that combined the aeration-ship technology and biological contact oxidation was applied to the eutrophic river water treatment of Dongfeng channel in Zhengzhou. The removal efficiency of combined packing and elastic packing to chemical oxygen demand, NH₃-N, TP in different dissolved oxygen (DO) and hydraulic loading showed that combined packing performance was better than elastic packing, and combined packing had optimal effect while DO was 3.8 (mg/L), hydraulic loading was 2.29~3.21(m³·m^-2·d^-1) in river restoration.
