摘　　要：制备了聚合硅酸氯化铝絮凝剂(PASC),其制备条件为常温,常压,反应时间3～4h。pH值3.0～3.5,产物Al2O3含量8.0%～10.0%,SiO2含量1.0%～2.0%。红外光谱证实聚铝离子与聚硅离子间存在着一种非离子性的键合作用,说明形成了聚合度更大的无机高分子聚合物。应用实验表明PASC较PAC的絮凝效果更好,稳定性更高。PASC coagulant was prepared. The optimum conditions of preparation are normal temperature, normal pressure, pH=3.0～3.5, the concentration of Al 2 O 3 =8.0%～10.0%, the concentration of SiO 2 =1.0%～2.0%.The IR spectrum proved that polyaluminium ion and polysilcic ion reacted and produced a non-ion bond effect which proved it produced more high polymeric degree inorganic high polymer. The experiment for application shows that PASC has more efficient coagulation than PAC, and the stability is more high.
