摘　　要：采用聚丙烯酰胺(PAM)和聚合FeSO4处理废水,在总反应时间为3.0 h、反应开始时加入0.050 mg/L絮凝剂的条件下,阴离子型H3064絮凝剂的效果最好,出水COD为122.6 mg/L,COD去除率可以达到76.50%。加入絮凝剂处理后,废水COD有明显下降。增加絮凝剂的加入量,可以普遍提高废水COD的去除率。加入絮凝剂絮凝后,与原始水样相比,处理后水样的浊度都有明显降低。本实验采用阴离子型H3064絮凝剂处理废水的效果较好,综合考虑经济效益,选择H3064加入量为0.020 ppm。With polyacrylamide （PAM） and polymerization FeSO4 processing waste water, when the total reaction time was 3,0 h and response start added the 0.050 mg/L flocculants under the condition, the effect of anion H3064 flocculants was best, water leakage COD was the 122.6 mg/L, COD MRR can achieve 76.50 %. After joining flocculants processing, waste water COD had the visible drop. Increased the flocculants the joining quantity, can universally raise the waste water COD MRR. After joining the flocculants flocculation, compared with primitive water sample, after processing, the turbidity of water sample had obvious reduction. The experiment used the anion H3064 flocculants processing waste water the effect to be good, considered all the factors in the economic efficiency, chose the H3064 joining quantity was 0.020 ppm.
