摘　　要：投加不同来源的聚合氯化铝，进行了一系列混凝烧杯实验，研究了铝盐形态分布、混凝剂剂量、水样pH值、初始浊度、水力条件对黄浦江水混凝效果的影响．实验结果表明，铝盐形态分布对混凝效果会产生一定影响，pH值对有机物含量高的原水有机物去除率影响显著，随着pH值的降低，CODMn去除率从22％上升到38％．当混凝剂达到一定浓度时，初始浊度在100～200NTU之间的水样通过混凝均能获得比较高的浊度去除率，平均去除率约为99．4％，高浊度去除率并不代表CODMn去除率也高．Using poly aluminium chloride with different scource, a series of coagulation beaker experiments are carried out, in order to study effects of coagulation including aluminium species distribution, dosage, pH value, initial turbidity and hydraulic conditions on the Huangpu River. The results indicate that the species distribution of poly aluminium chloride would influence coagulation effect, and pH value has a significant impact on the rate of organic matter removal for water with high organic content,CODMn, removal rate increases from 22% to 38% with decreasing pH. When coagulant dosage is proper, raw water with initial turbidity between 100 - 200 NTU could have higher removal rate of turbidity, and average value is 99.4%. But high turbidity removal rate does not mean the CODMn removal rate is high.
