摘　　要：为了探索适合杨柳青水厂生产运行的强化混凝预处理技术,采用小试和中试相结合的方式,对比考察了FeCl3、硫酸铝(AS)以及两者复配混凝对后续超滤工艺处理效果的影响。结果表明:在相同的混凝剂投加量下,采用FeCl3进行混凝预处理时,超滤膜出水的有机物浓度最低、膜污染程度最轻;而采用AS作为混凝剂时,中试系统的运行效果最差;FeCl3与AS复配的协同作用不显著。In order to explore an enhanced coagulation pretreatment technology suitable for Yangli-uqing WTP, the effects of FeCl3 , AS and a combination of both on uhrafihration membrane process were investigated in laboratory and pilot tests. The results showed that the lowest organic concentration and the lowest level of membrane fouling in the ultrafihration membrane were achieved using FeCl3 at the same dosage. The operation efficiency of the pilot test system was the lowest when using AS as coagulant. The synergistic effect of FeC13 and AS was not obvious.
