聚合氯化铝-聚丙烯酰胺混凝除浊的协同效应

Synergistic effect of PAC-PAM coagulation on turbid remove

通过对芜湖赭山东路神东村上新塘市政合流污水在不同条件下进行的混凝对比试验，研究聚合氯化铝一聚丙烯酰胺混凝效果影响因子之间的交互效应。由正交试验设计安排水处理剂对原水除浊率影响试验。结果表明：在水处理剂的混凝条件中，药剂种类和比例的交互作用对浊度处理率有一定程度的协同效应。温度为20℃时，当用聚合氯化铝一聚丙烯酰胺进行水处理时，pH值为7．5～8．4，1L原水投加药剂80mg，组分V（PAC）：V（PAM）=8：2时，混凝效果最优，除浊效率达到93．18%。

Abstract. This paper introduces the contrast coagulation experiment of different coagulation conditions of Wuhu Shangxintang civil waste water, the interaction of the flocculation effect factors is discussed. The result shows that the interaction of the flocculation factors to turbid remove exists certain synergistic effect. When tested at 20 ℃ ,pH= 7.5～8.4 ,PAC-PAM co-use disposal of waste water, the total reagent to be added is 80 mg for every liter waste water, and the optimized weight proportion of reagent component is V （PAC） ： V （PAM）=8 ： 2,the turbid remove efficient being 93.18%.
