摘　　要：本文采用混凝-离子交换-活性炭吸附-消毒组合工艺处理城市生活污水,开发了新型混凝剂,并选用斜发沸石作为离子交换材料。结果显示,最终出水COD低于20mg/L,NH3-N浓度在10mg/L以下,PO4-3-P浓度约为0.35mg/L,浊度为5度。A combined technique which included coagulation,ion-exchange,active carbon adsorption and disinfection was studied to treat municipal sewage, and a novel coagulant was explored. Zeolite was adopted to make ion-exchange. The results showed as follows：in the effluent, COD was lower than 20 mg/L and concentration of NH3-N was below 10 mg/L. Concentration of PO43-p was about 0.35 mg/L and turbidity was 5 degrees.
