| 摘 要： | 以氯化锌、氯化铝、盐酸和聚丙烯酰胺为主要原料,制备了无机-有机锌基复合絮凝剂.以浊度去除率为考察指标,探讨了制备过程中ZnCl2、AlCl3、PAM和HCl的投加量对锌基复合絮凝剂絮凝效果的影响.结果表明,锌基复合絮凝剂的最佳制备条件:ZnCl2质量分数为10％,AlCl3质量分数为10％,PAM质量分数为0.015％,HCl质量分数为3％.与铝盐复合絮凝剂和铁盐复合絮凝剂相比,锌基复合絮凝剂具有絮凝沉降快、污泥体积小等特点.

| Abstract: | Using zinc chloride,aluminum chloride,hydrochloric acid and polyacrylamide as main raw materials,the inorganic-organic zinc-base composite flocculant has been prepared.Turbidity removal rate is the investigation norm.The impact of the dosages of ZnCl2、AlCl3、PAM and HCl on the flocculating efficiency of zinc-base composite flocculant is discussed.The results show that the optimum preparation conditions of zinc-base composite flocculant are as follows:the mass fractions of ZnCl2,AlCl3,PAM and HCl are 10%,10%,0.015% and 3%,respectively.In comparison with aluminum-salt composite flocculant and iron-salt composite flocculant,the zinc-base composite flocculant is characterized by quick flocculating settling and small sludge volume. |
