摘要 采用强化混凝-超滤组合工艺对湘江水进行了净化研究,通过加入不同的混凝剂[Al2(SO4)3?18H2O、FeCl3]以及粉末活性炭(PAC),比较了三者对于湘江水的处理效果和对膜过滤性能的影响.结果表明,混凝剂的选择与用量对水中污染物质的去除和膜过滤性能有很大的影响.经过组合工艺处理后,系统出水的浊度小于0.1NTU,TOC小于2mg/L,铁、锰的含量低于0.1mg/L. Purification study of Xiangjiang River water was carried out adopting the combined technique of enhanced coagulation and ultrafiltration （UF）. Through adding different coagulants：Al2（SO4）3·18H2O、FeCl3 and powered activated carbon （PAC）, their treating effect of Xiangjiang River water and influence on film filtration property were compared, finding that selection and use amount of coagulant had great influence on the removal of pollutants in water and the filtration property. After combined technique treatment, the system effluent turbidity was less than 0.1NTU, TOC less than 2mg/L, Fe and Mn contents less than 0.1mg/L.
