摘　　要：二氯嘧啶生产废水具有高矿化度、高COD和高色度特性,对环境污染严重,处理难度较大。采用Fe-C微电解-Fenton氧化-深度氧化-吸附等组合工艺处理二氯嘧啶生产废水,考察了进水pH、反应时间、H_2O_2加量、活性炭加量、氧化剂加量对废水处理效果的影响。优选出最佳处理工艺条件。采用此处理工艺处理二氯嘧啶生产废水,COD可降至18. 5 mg/L,色度总去除率为100%,水样颜色由棕黄色变为无色,出水COD和色度达到了国家一级排放标准。Dichloropyrimidine wastewater has the characteristics of high salinity,high COD and high chromaticity, which is seriously polluted and difficult to treat.The iron-carbon micro-electrolysis-Fenton oxidation-adsorptionoxidation combined process was used in the treatment of dichloropyrimidine wastewater.The effects of influent pH, reaction time,amount of H2O2,amount of activated carbon and amount of oxidant on wastewater treatment were investigated.The optimum treatment conditions were optimized.After treatment,the effluent COD was 18.5mg/L,the color removal rate was 100%,the color of the water sample changed from brown to colorless,the effluent COD and chroma could reach the national discharge standard of one grade.
