摘　　要：提取硫酸铝渣的SiO2 与Al制得了聚硅酸硫酸铝絮凝剂,用其处理了模拟浊水、生活污水与垃圾填埋场渗滤液的生化处理尾水,研究并分析了处理不同污水的适宜pH范围,观察了处理生活污水的微观过程。The polyaluminium silicate sulfate flocculants was prepared by extracting SiO_2 and Al from bauxite slag. The polyaluminium silicate sulfate flocculants was applied to treat simulating turbid water, municipal wastewater and landfill leachate after anaerobic and aerobic processes respectively, the different pH ranges being appropriate for above different water. The micro processes of treating municipal wastewater were observed.
