摘　　要：以上海某水厂的两路水源为研究对象,对比了聚合氯化铝(PAC)与复合聚硫氯化铝(FPAC-3)在不同温度下的絮凝效果。研究表明:高温条件下(>20℃)PAC絮凝效果比FPAC-3更优;秋冬季(<20℃)陈行原水可继续使用PAC,但将头部原水改为投加FPAC-3可达到强化絮凝的效果。对比分析了冬季条件下几种絮凝剂处理头部原水的絮凝沉淀效果,结果表明:高效PAC的絮凝效果最好,FPAC-3制水成本最低,而Al2(SO4)3性价比最低,水厂当前使用的PAC絮凝效果和制水成本居中。Considering two kind of raw water from a water treatment plant as study object,flocculation effect of PAC and FPAC-3 under different temperature was compared.It is showed by the jar tests that PAC performs in flocculation effect better than FPAC-3 at higher temperatures（〉20 ℃）;during winter and autumn,PAC is more suitable for Chenhang reservoir raw water;while FPAC-3 is better than PAC for raw water from Huangpu River.Different efficiencies among four coagulants for the treatments of raw water from Huangpu River in winter were also studied.The results demonstrate that strengthened PAC has the best performance,FPAC-3 is the cheapest,Al2（SO4）3 is the lowest cost-effective,and PAC ranks in the middle.
