摘要
以水玻璃、硫酸铝等为原料制备了新型无机高分子絮凝剂—聚硅酸硫酸铝（简称ＰＳＡＡ），探讨了其最佳工艺条件，试验了其对生活污水及印染废水的絮凝和脱色效果，并与聚合氯化铝（ＰＡＣ）、聚合硫酸铁（ＰＦＳ）进行了性能比较，结果表明ＰＳＡＡ具有良好的絮凝及脱色效果。
A new type of inorganic macromolecule flocculant, polysilicic aluminium sulfate, has been prepared taken the water glass and aluminium sulfate as the raw materials. The technical conditions were optimized. And the effectiveness of decolourisation and flocculation to the domestic sewage and printing and dyeing waste water was also tested. Compared with the polyaluminium chlorate and polyferric sulfate, the new flocculant is good at decolourisation and flocculation.
