摘　　要：以硅酸钠、三氯化铁、聚丙烯酰胺为原料，制备了高效高分子混凝剂，初步研究了其对乳品废水的絮凝净化效果，考察了SiO2的质量分数、硅与铁的摩尔比、投药量、pH值等的影响，得出了最佳制备工艺条件为：SiO2％=2．0%，pH=2．0～3．0，聚合时间为1h，熟化时控制Si／Fe^3＋=3（摩尔比），反应时间为2h，该产品对pH值为8～13范围内的乳品工业废水具有良好的絮凝效果。The process of preparation high-effective macromolecular flocculant from sodium silicate, FeCl3and PAM was developed. The flocculating effect on milk wastewater was primary studied and the influence of mass fraction of SiOz, Si/Fe^3＋ mole rate, amount of flocculant and pH value were investigated. The optimum preparation conditions were follows . SiO2%=2.0%,pH=2. 0-3.0, the flocculation time of 1 hours,aging time of 2 hours in the condition of Si/Fe^3＋=3（mole rate）. The experiment showed that the composite flocculant has good flocculating effects on milk wastewater when pH value is 8- 13.
