摘　　要：采用磁絮凝-陶瓷膜过滤组合工艺对微污染水进行处理,研究不同条件下的出水水质,分析PAC投加量、磁粉投加量以及磁化时间对出水水质的影响。通过正交实验确定其主要影响因素的最佳水平组合:PAC投加量为25 mg/L,磁粉投加量为8 mg/L,磁化时间为6 min。在此条件下对浑浊度、UV和COD的去除率可分别达到92.32%、58.50%和43.40%。Micro polluted water was treated by magnetic flocculation and ceramic membrane filtration process. The quality of effluent was studied. The effects of, magnetic particles dosage and the magnetization time on the quality of the effluent were studied. Through orthogonal experiment to obtain the main influencing factors of the optimal level combination： PAC dosage is 25 rag/L, the magnetic particles dosage is 8 rag/L, and the magnetization time is 6 min. Under these conditions, the removal rates of tnrbidity, UV and COD can reach 92.32%, 58.50% and 43.40% respectively.
