摘　　要：以Fe Cl3为混凝剂,聚丙烯酰胺(PAM)为助凝剂,研究了混凝剂投加量、p H和温度等对采油废水化学需氧量(COD)和浊度去除效果的影响。通过正交试验确定最佳混凝条件:温度为室温(20℃),Fe Cl3、PAM投加量分别为300.00、0.50 mg/L,p H=7。在此条件下,采油废水的浊度去除率为95.89%,COD去除率为54.50%。采用芬顿氧化法对废水作进一步处理,COD的去除率达到64.80%。The effects of the coagulation dosage, pH and the temperature on turbidity and COD removal rate were studied. The results demonstrated that the optimum conditions were the room temperature, FeCl3 dosage of 300.00 mg/L, PAM dosage of 0.50 mg/L and pH 7. Under these conditions, turbidity and COD removal rates of oil extraction wastewater were 95.89% and 54.50%,respectively. Fenton oxidation was used to further tackle the wastewater, and COD removal rate could reach to 64.80%.
