摘要
制备了聚合氯化铝铁-淀粉-丙烯酰胺(PAFC-ST-AM)复合絮凝剂,考察了PAFC与ST-AM的质量配比、反应液的pH值和复合时间等复合反应条件。通过对含磷模拟废水的絮凝试验[正交L9(34)],得出了复合絮凝剂的最佳应用条件。结果显示,当PAFC∶ST-AM为4∶1,投加量为5mL/500mL,pH值为8时,磷的去除率可达92.36%。
Compound flocculant PAFC-ST-AM was prepared with varying compound reaction conditions,such as the mass ratio of PAFC with ST-AM,pH value and compound time. The best applied conditions of the compound flocculant were obtained by orthogonal experiment [L9（34）] on simulated waste water containing phosphorus. The removing rate of phosphorus can be up to 92.36% when the PAFC：ST-AM is 4∶1,flocculant dosage is 5 mL/500 mL and pH value is 8.
