摘　　要：采用接触氧化反应器处理农村分散污水，通过实验确定了适宜的工艺参数，研究表明采用接触氧化反应器处理农村污水，在反应器内溶解氧（DO）质量浓度维持在2．0～4．0mg／L，水力负荷为3．53m^3／（m^2·d）的运行条件下，对COD，NH4^＋-N及TN去除率分别达到76．10％，68．12％，60．50％，出水可稳定达到GB18918-2002《城镇污水处理厂污染物排放标准》一级B标准。The Contact oxidation reactor was used to treat rural scattered sewage. The appropriate operating parameters were determined through pilot-scale experiment. The dissolved oxygen （DO） should be kept between 2.0 to 4.0 mg/L and the hydraulic loading was 3.53 m3/（m2.d）. The research shows that 76.10% of COD, 68.12% of NH4^＋-N and 60.50% of TN can be removed in the efficient integrated reactor under the above operating condition. And the effluent can meet the first grade B of the discharge standard of pollutants for municipal wastewater treatment plant （GB 18918-2002）.
