摘　　要：在废水传统微电解处理工艺的基础上,增加了H2O2/O2处理,实验结果表明:在pH值4.5,Fe/C=1:1,反应时间40min,H2O2加入量0.8mg·L-1废水,曝气头1个的条件下,H2O2/O2对传统微电解工艺具有加强作用,出水色度48倍,CODCr为51mg·L-1,达到最新造纸行业废水排放标准。且该工艺较适合作为二级生化前的预处理或后处理工艺。In the conditions of pH 4.5, iron/carbon 1：1, reaction time 40 min, hydrogen peroxide 0.5 mg·L^- 1 wastewater, one oxygen with micro-electrolysis process which was enhanced by hydrogen peroxide and oxygen. e results showed that COD Cr is about 51 mg·L^- 1 and the chromaticity is about 48 times, which up to the newly national papermaking wastewater standard. It was also indicated that the process is fit for pretreatment or deep treatment.
