摘　　要：以上海石化股份公司污水处理厂二级处理出水为处理对象,采用混凝沉淀+流砂过滤、流砂微絮凝过滤和流砂直接过滤三种工艺,试验结果表明混凝沉淀+流砂过滤工艺对CODCr和浊度的去除效果最好,CODCr进水平均浓度50.4mg/L,浊度4.2NTU时,CODCr平均出水浓度为42.3mg/L,浊度仅为0.6NTU,CODCr和浊度均能达到小于50mg/L和3NTU的回用水标准。Three different processes of coagulation/settling/sandflo-filtration, micro-flocculation/sandflo-filtration and direct sandflo-filtration without dosing chemical are employed in advanced treatment of the secondary treatment effluent from wastewater treatment plant in Shanghai Petrochemical Share Co. Ltd. Results show that the performance. of eoagulation/settling/sandflo-filtration is the best. Average concentration of CODCr is 42.3 mg/l in effluent with 50.4 mg/l in influent, average concentration of 0.6NTU in effluent with 4.2NTU in influent for turbidity, which the two parameters in effluent completely come to the standard for water reuse.
