摘　　要：采用铁碳微电解-H2O2耦合联用的类Fenton法处理制浆造纸废水,研究了Fe/C、pH、H2O2投加量、反应时间等因素对处理效果的影响和优化.结果表明,pH值为3,Fe/C质量比为1∶1,H2O2投加量0.0146 mol·L-1,曝气反应时间75 min为最优反应条件,对COD的去除率达到75.43%,也显著降低了色度和悬浮颗粒物,大大减少了运行费用,是一种深度处理造纸废水的有效方法.此外,还与铁碳微电解进行对比,结果表明,铁碳微电解/H2O2耦合联用的类Fenton法对制浆造纸废水COD去除具有明显的加强作用.Iron-carbon micro-electrolysis-H2O2 combination system was applied for pulp and paper wastewater treatment,and the effect of Fe/C, pH, H2O2 dosage, reaction time on removal efficiency of pulp-paper wastewater was investigated. The results showed that the optimal reaction condition was： pH = 3, H2O2 dosage =0.0146 mol. L^-1, Fe/C = 1 ： 1, reaction time = 75 min. The removal efficiency of COD reached 75.4%, and chromaticity and suspended substance decreased dramatically. In addition, the reaction process of iron-carbon micro-electrolysis-H2O2 combination system was also discussed.
