摘　　要：简述了在低温时以跌水曝气接触氧化法为主体的污水处理工程对低浓度农村生活污水的处理效果,该工艺出水COD、TN、TP分别低于70mg/L、5mg/L、0.1mg/L,均能达到城镇污水处理厂污染物排放的一级标准(GB18918-2002),对富营养化水体流域内农村生活污水的处理具有指导意义。A sewage treatment project with water dropping aerating- bio-eontaet oxidation process at low temperature and its treating effect on rural domestic sewage were introduced briefly. It was shown that COD,TN,TP in effluent were lower than 70mg/L,5 mg/L,0.1 mg/L, reaching the first class discharge standard of urban sewage treatment factory （GB18918-2002） and having guiding significance for the treatment of rural domestic sewage in the area with eutrophication water.
