【摘要】 将聚合氯化铝铁(PAFC)与聚丙烯酰胺(CPAM)复配用于处理城市生活污水,通过絮凝搅拌实验确定出对COD处理效果最佳复配投加量为:PAFC投加量32mg/L,CPAM为6mg/L,PH为6～8。此条件下对COD去除效果最好。单一絮凝剂絮凝效果明显没有PAFC与CPAM复配絮凝效果好。更多还原

【Abstract】 Polyaluminium ferric chloride(PAFC) and polyacrylamide(CPAM) were compounded to treat municipal domestic sewage. Through flocculation and stirring experiments, it was determined that the best compounding dosage treatment was 32 mg/L for COD and 6 mg/L for CPAM and pH was 6-8. Under these conditions, COD removal effect is the best. The flocculation effect of single flocculant is obviously not as good as that of PAFC and CPAM.更多还原
