摘　　要：通过实验研究了微电解和Fenton高级氧化单独处理DDNP废水,结果表明:两者单独处理DDNP废水时,COD去除率可分别达到60.28%、80.54%。同时对微电解与Fenton耦合预处理DDNP废水进行了实验研究,静态实验结果显示,用这一方法在降低成本的同时,COD去除率可进一步提高,耦合效果明显;动态处理实验结果表明,连续运行156 h,在前72 h内,其COD去除率在80%以上。DDNP wastewater treated by separate micro-electrolysis and Fenton oxidation processes has been studied by experiment.The results show that COD removing rates could reach 60.28% and 80.54%,respectively. And,the micro-electrolysis-Fenton coupling process used for the pre-treatment of the DDNP wastewater has also been studied. The static experiment results show that,by using this process,not only the cost could be lowered,COD removing rate could also be further improved,and the coupling effect is obvious. Dynamic treatment experiment results show that while the device continuous runs for 156 h ,its processing effect could reach more than 80%in the first 72 h.
