摘　　要：国家强制要求城镇污水厂将尾水的排放标准由一级B提高至一级A,且通过政策以及经济手段鼓励企业开展再生水的回用。混凝过滤工艺用于深度处理可以有效去除SS和总磷,使用聚合氯化铝、硫酸铝和氯化铁作为混凝剂对比实验。使用PAC作为混凝剂,深度处理后出水总磷可以达到0.1 mg/L,SS基本可以稳定在8mg/L以下。In recent years,the government has forced the municipal wastewater treatment plants to increase the discharge standard from one-level B to one-level A. And enterprises are encouraged to reuse of recycled water through policies. Coagulation filtration process for advanced treatment can effectively remove SS and TP. Comparison test were made by polyaluminium chloride,aluminum sulfate and ferric chloride. After using PAC as coagulant,TP of effluent can reach 0.1 mg/L,and SS can be stabilized below 8 mg/L.
