This research deals with the experimental results obtained by the pilot plant of an upgraded Rotating Biological Contactor(RBC). This is a two-story RBC which is designed to simultaneously achieve the biological oxidation and removal of detached biomass in the trough. The authors constructed a three-stage pilot plant with an octagonal stainless mesh contactor 2 m across to collect the design information of an upgraded RBC.The municipal wastewater treatment was conducted to examine the RBC's performance. According to experimental results, with a contactor rotating speed of 2 rpm, the effluent TOC and NH_4-N concentrations were about 10 g/m^3 and 5 g/m^3, respectively, at the hydraulic loading of 70 L/m^2/d, corresponding to a BOD loading of about 8 g/m^2/d. The electrical power consumption of the RBC was 0.005 kwh/m^2/d at a contactor rotating speed of 1 rpm. A jet mixed separator (JMS) was used as the physico-chemical pre-treatment unit of the RBC.With the addition of a coagulant, simultaneous flocculation and sedimentation of the suspended particles occurred in the JMS.This combined system of the JMS and RBC produced a clean effluent.

本文介绍了改进后的旋转生物接触器（RBC）中试装置的试验结果。这是一个双层RBC，旨在同时实现生物氧化和去除槽中分离的生物质。作者建立了一个3级中试装置，采用直径为2 m的八角形不锈钢网接触器，收集了改进后的RBC的设计信息，并进行了城市污水处理试验，以检验RBC的性能。实验结果表明，当接触器转速为2 rpm，水力负荷为70 L/m^2/d时，出水TOC和NH_4-N浓度分别为10 g/m^3和5 g/m^3左右，对应的BOD负荷为8 g/m^2/d左右。在接触器转速为1 rpm时，RBC的电力消耗为0.005 kwh/m^2/d。采用射流混合分离器（JMS）作为红细胞的物化预处理单元，通过加入混凝剂，使悬浮颗粒在JMS中同时发生絮凝和沉降，形成JMS与红细胞的组合系统，得到清洁的出水。
