摘　　要：进行了直接超滤和微絮凝—超滤处理微污染水库水的中试研究。结果表明:两组超滤工艺的出水水质均符合建设部《城市供水水质标准》(CJ/T206—2005)要求;微絮凝—超滤工艺在改善出水水质和缓解膜污染方面均优于直接超滤工艺;微絮凝—超滤工艺的最佳混凝时间为120s左右,聚合氯化铝的最佳投量为2mg/L左右(以Al2O3计),在相同的投量(即相同的物质的量浓度,以金属离子计)下铁盐比铝盐的混凝效果好。Micropolluted reservoir water was treated with the direct ultrafiltration process and the combined process of micro-flocculation and ultrafiltration. The experimental results show that the treated water quality by two kinds of ultrafiltration processes conforms to the requirements of Water Quality Standardfor Urban Water Supply （CJ/T 206 -2005 ） issued by the Ministry of Construction. The combined process of micro-flocculation and ultrafihration is more effective than the direct ultrafiltration process, both in improving treated water quality and reducing membrane fouling. In the combined process, the optimum flocculation time is about 120 seconds; the optimum dosage of PAC is about 2 mg/L （calculated as A12O3 ）. With the same dosage （ mol/L metal）, the flocculation effect of iron salt is better than that of aluminium salt.
