摘　　要：采用微电解+Fenton法处理DDNP废水,考虑微电解系统的活性炭的投加量,Fe/C,pH,反应时间等因素在不同条件下原水的COD去除情况及色度变化。实验结果表明,最佳pH为4,Fe的投加量为30 g/L,最佳Fe/C为3/2,最佳反应时间60 min。COD的去除最高可达到58.8%。Fenton系统H2O2的投加量为4 mg/L,微电解+Fenton系统的COD去除率为87.53%。The use of micro-electrolysis ＋ Fenton DDNP wastewater treatment, considering the micro-electrolysis system activated carbon dosage, Fe/C, pH, reaction time and other factors under different conditions COD removal of raw water conditions and color changes. The experimental results showed that the optimum pH was 4, Fe dosage of 30 g/L, the best Fe/C was 3/2, the optimal reaction time 60 min. COD removal can reach 58.8 %. Fenton system of H202 dosage was 4 mg/L, micro-electrolysis ＋ Fenton system COD removal efficiency was 87.53 %.
