| 摘 要： | 在室温条件下,分别选用聚合氯化铝(PAC)、聚合氯化铝铁(PAFC)及三氯化铁(FeCl3)对玉米深加工废水进行混凝实验。综合考虑各种混凝剂对磷、COD以及SS的去除效果,最终选取PAC作为混凝剂。采用PAC和聚丙烯酰胺(PAM)作为复合混凝剂,对其去除效果做进一步研究,并确定了最佳投加量及pH值。实验结果表明,在PAC投加量25mg/L,PAM投加量0.5 mg/L,pH为8条件下,混凝效果最佳。磷、COD、SS去除率可分别达到90.1%、53.3%和88.2%,对应的出水质量浓度分别为0.41、26.8和2 mg/L。 |

| Abstract: | Three kinds of coagulant agents,polyaluminum chloride(PAC),polyaluminum ferric chloride(PAFC) and ferric chloride(FeCl3),were used to treat the corn in-depth processing wastewater.PAC was chosen as the optimum coagulant agent and the following experiment adopted the PAC mixed PAM as the optimal coagulating agent.The result showed that effect of coagulation is the best with the PAC dosage of 25 mg/L,the PAM dosage of 0.5 mg/L and the pH of 8.The removal rates of phosphorus,COD and SS could be up to 90.1%,53.3% and 88.2%,respectively,with which concentrations were 0.41,26.8 and 2 mg/L. |
| Keywords: | coagulation corn in-depth processing wastewater coagulant agents optimum dosage |
