摘 要: | 利用Fenton+MnO_2+A/O组合工艺处理过氧化甲乙酮生产废水。在Fenton+MnO_2预处理阶段对影响废水COD去除率的主要因素进行了考察,得到反应的最佳条件:p H=2.7,30%H_2O_2投加量为0.1 L/L,FeSO_4·7H_2O投加量为5 g/L,MnO_2投加量为8 g/L,MnO_2氧化反应时间为45 min。废水经Fenton+MnO_2氧化预处理后可生化性由0.14提高到了0.25左右。废水经Fenton+MnO_2+A/O组合工艺处理后,出水COD稳定低于500 mg/L。

Abstract: | The combined process,Fenton+MnO2+A/O has been used for treating methylethyl ketone peroxide proces-sing wastewater. The key factors affecting the wastewater COD removing rate in the stage of Fenton+MnO2 pretreat-ment are investigated. The results show that the optimum conditions are as follows:the pH is 2.7,dosage of 30%of H2O2 0.1 L/L,dosage of FeSO4·7H2O 5 g/L,dosage of MnO2 8 g/L,and MnO2 oxidation reaction time 45 min. After the wastewater has been pretreated by Fenton+MnO2 oxidation process,its biodegradability can be improved from 0.14 to about 0.25. After the wastewater has been treated by Fenton+MnO2+A/O process,the effluent COD is stably lower than 500 mg/L. |
