摘　　要：采用粉末活性炭(PAC)与超滤(UF)的组合工艺深度处理吴淞水厂的常规工艺滤后水,结果表明,该工艺能够有效地保证出水水质,且超滤膜的过滤性能稳定;经处理后,颗粒物、溶解性有机物和THMs等指标的含量都得到了不同程度的降低;PAC投量达到一定值后对有机物的去除效果提高不大,宜将其投量控制在16mg/L左右。Combined process of powdered activated carbon （PAC） and uhrafiltration （UF） was used to treat the treated water of sand filter in Wusong Water Treatment Plant. The results show that the PAC/UF process can guarantee a good water quality, and the UF membrane has stable filterability. Wa- ter quality indexes, such as SS, DOM and THMs, can be lowered to some extent. PAC dosage should be controlled at about 16 mg/L, because the higher dosage has little improvement on the removal of DOM.
