摘　　要：以Na2SiO4和Al2(SO4)3为原料,采用复合法制备聚合硅酸硫酸铝(PASS):先在碱性条件下制备聚硅酸,然后在酸性条件下制备PASS。将自制的PASS应用于实际废水的处理并与聚合氯化铝(PAC)进行了比较,研究结果表明,所制备的PASS具有优良的絮凝性能,其在除浊、脱色及去除COD等方面较PAC具有更好的絮凝效果,是一种有广阔发展前景的新型高效净水剂。Using Na2SiO4 and Al2（SO4）3 as raw materials,compounding method was adopted to prepare polyaluminium silicate sulfate（PASS）.First polysilicate was prepared under alkaline condition,and then PASS was prepared under acidic condition.The PASS was applied in the treatment of actual wastewater and compared with the PAC.The research results showed that PASS had an excellent performance of flocculation ability,and had a better flocculation effect than PAC in the aspects of removing turbidity,decoloration and COD.
