摘要
通过混凝沉淀烧杯试验,对絮凝剂聚氯化铝（PAC）和聚合氯化铝铁（PAFC）,助凝剂聚丙烯酰胺（PAM）和改性活化硅酸进行了优选,最终确定聚合氯化铝配合改性活化硅酸的混凝沉淀效果最佳.混凝的最佳pH值介于6.5 ～7.5;另外发现,兼顾除浊和除有机物的效果评价和优选混凝剂,是提高混凝沉淀工艺除污染效率的有效途径之一.
The coagulation-flocculation and sedimentation beaker test is conducted to compare the flocculating and sedimentation effects of and polymeric aluminum, （ PAC ）, （ PAFC ）, （ PAM ） and activation silicic acid. The results show that polymeric aluminum and activation silicic acid is the most effective for the treatment of low temperature and turbidity raw water. The optimum pH for coagulation is 6. 5 - 7. 5. Under optimal coagulating conditions coagulation with ferric chloride is the best. It can also be seen that it＇s efficient to evaluate and choose coagulants with respect to turbidity removal efficiency in coagulation and sedimentation. and organic substance removal for increasing pollutant
