摘　　要：利用粉煤灰为原料,制成一种新型无机高分子絮凝剂聚硅酸硫氯化铝铁(PSiAFCS),考察了其对赣江水样的絮凝效果,并与聚硅酸氯化铝铁(PSiAFC)、聚氯化铝(PAC)的絮凝效果进行了比较。试验结果表明,絮凝剂投加量为1.00～6.25mg·L-1,pH在6～11,静置时间20min,絮凝水温在20～60℃范围内具有很好的絮凝去浊效果,该絮凝剂的除浊效果要优于其它絮凝剂。Poly-Silicate Aluminum Ferric Chloride Sulfate （PSiAFCS）, a new type of inorganic polymeric flocculation was prepared with coal fuel ash. The factors affecting the flocculating effect were investigated. At the same time, the flocculating effect ofPSiAFCS, PSiAFC and PAC on the Ganjiang river was compared. The result showed that optimal preparation conditions were as follows： PSiAFCS dosage 1.00-6.25 mg· L^-1, pH 6-11, the standing time 20 min, the temperature of waste water 20-60℃. And PSiAFCS was superior to other floeculants with respective to the turbidity removal.
