摘　　要：采用直接超滤、气浮/超滤两种工艺对微污染高藻水库原水进行处理。结果表明,气浮/超滤组合工艺的净化效果明显优于直接超滤工艺;组合工艺对CODMn和UV254的去除率分别为60%和50%,对嗅味物质土臭素的去除率为42%,对三氯甲烷、四氯化碳前体物的去除率分别为61%和99.7%,而对浊度、叶绿素a的去除率则接近100%。The direct UF process and combined process of air flotation and UF were used to treat algae-laden reservoir water. The results show that the combined process of air flotation and UF is better than direct UF process in purification effect. The removal rates of CODMn, UV254, geosmin, chloroform and carbon tetraehloride precursors are 60% , 50% , 42% , 61% and 99.7% respectively, and the removal rates of turbidity and chlorophyll a are close to 100% in the combined process.
