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%,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 used aluminum sulfate, water glass and sodium aluminate as raw materials. The flocculating efficiency of PASS was also examined by Jartest. Modification of PASS polydimethyl dially ammonium chloride（PDMDAAC） and polyacrylamide（PASS） was studied. The results showed that PASS had high flocculation performance, the removal percentage of turbidity was 97% and it could decrease the dose of PASS distinctly when PDMDAAC was used as modifying agent.
