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PAFCST-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L934],得出了复合絮凝剂的最佳应用条件。结果显示,PAFCST-AM41,投加量为5 mL/500 mLpH值为8时,磷的去除率可达92.36%

Abstract:

Compound flocculant PAFC-ST-AM was prepared with varying compound reaction conditionssuch as the mass ratio of PAFC with ST-AMpH value and compound time. The best applied conditions of the compound flocculant were obtained by orthogonal experiment [L934] on simulated waste water containing phosphorus. The removing rate of phosphorus can be up to 92.36% when the PAFCST-AM is 41flocculant dosage is 5 mL/500 mL and pH value is 8.
