含二甲基甲酰胺高浓度COD废水处理方法研究

Study on the treatment method of the high-strength dimethylformamide-contained COD wastewater

文章通过萃取实验实现含DMF废水的资源回收利用。萃余液采用Fenton试剂氧化处理,实现DMF废水COD的达标排放。在此过程中确定该废水的处理最佳条件,并进一步确定一个合理的DMF废水处理工艺流程。

This paper realizes the resource recycling of DMF-contained wastewater through extraction experiments.The extraction raffinate was oxidation treated by Fenton reagent to realize the standard discharge of the DMF wastewater——COD.In this process,the optimal treatment condition of the wastewater should be determined to further determine a reasonable DMF wastewater treatment technology procedure.
