摘　　要：用混凝剂聚合氯化铝 ( PAC)和硫酸铝 ( AS)对模拟废水进行处理 ,以 ζ电位作为指标对混凝剂的水处理性能进行评价。结果表明 ,废水经混凝剂处理后 ,絮体ζ电位的大小与 PAC的 Al2 O3含量、盐基度以及 AS的 Al2 O3 含量、铁含量和水不溶物含量等理化指标有较密切的关系。ζ电位在一定程度上可反映混凝剂水处理效果的好坏 。Treating capacity of coagulant polymeric aluminum chloride(PAC) and aluminum sulfuric acid (AS) for simulated waste water was studied by using ζ potential as an evaluating index. The results showed that content of Al 2O 3 and salinity of PAC, content of Al 2O 3, Fe and undissolved matter of AS were the main factors to affect treating capacity, ζ potential can be uesed as a evaluating paramater for coagulants treat capacity.
