摘　　要：文章采用铁屑微电解-Fenton联用法对微污染水的处理进行了实验研究,探讨了反应时间、pH值及双氧水质量浓度等条件对微电解和Fenton反应阶段处理效果的影响。结果表明,当原水pH=6,单独微电解反应1 h,CODMn去除率可达到63%。单独微电解出水再进行UV/Fenton反应,在双氧水投加量10 mg/L,反应时间为1 h,弱酸性条件下,CODMn去除率可达到80%。An experimental study has been made of the ferric-carbon micro-electrolysis and oxidation treatment of lightly-polluted water. The ferric-carbon micro-electrolysis experiment and the Fenton reaction experiment were carried out separately, and the CODMn degradation efficiency was obtained. The results indicate that in the ferric-carbon micro-electrolysis, when the pH value of the original water was 6 and the reaction was kept for 1 h, the CODMn degradation efficiency could reach 63%. Then the discharged water was used as the input water for the UV/Fenton reaction. When the ρ（H2O2） was 10 rag/L, and the reaction was kept for I h under the weak acid condition, the CODMn degradation efficiency could reach 80%.
