摘　　要：以硫酸铝,水玻璃和铝酸钠为原料制备了聚合硅酸硫酸铝(PASS),研究了PASS絮凝性能,并利用聚二甲基二烯丙基氯化铵(PDMDAAC)和聚丙烯酰胺(PAM)对PASS进行复合改性。结果表明PASS絮凝性能良好,除浊率高达97%,通过加入少量PDMDAAC对PASS改性后能显著减少PASS用量。A inorganic polymer flocculants polyaluminum silicate sulfate was prepared by using aluminum sulfate, water glass and sodium aluminate. The flocculating efficiency of PASS was also preliminarily examined.Modification of PASS by using polydimethyl dially ammonium chloride （PDMDAAC） and polyacrylamide （PASS） was studied. The results show that PASS had a high flocculation performance, the percentage of removal of turbidity is 97%and it can descrease the dose of PASS distinctly when using PDMDAAC as a modifying agent.
