摘　　要：探讨了铁碳微电解-Fenton耦合+磁粉类Fenton工艺对有机磷农药废水的处理效果。结果表明,在p H为1、双氧水(H_2O_2质量分数30%)投加量为4 m L/L、曝气1.5 h条件下,Fe/C-H_2O_2对废水中TP的去除率达到58.84%;处理后的出水再进行磁粉/H_2O_2类Fenton处理,在双氧水(H_2O_2质量分数30%)投加量为7.5 m L/L、磁粉投加量为7.5g/L、45℃下曝气2 h的实验条件下,废水中TP的去除率为67.59%。最终出水COD为425 mg/L,TP的质量浓度18.96 mg/L,达到预处理指标。High organic phosphorus pesticide wastewater was treated by Fe/C micro-electrolysis-Fenton coupled magnetic Fenton-like process. The results indicated that, in the Fe/C- H2O2 reaction, the removal rate of TP could reach 58.84% when the pH was 2, the dosage of Hydrogen peroxide solution （mass fraction of H20230%） was 4 mL/L, the aeration time was 1.5 h. Then the effluent was treated by Fenton-like reaction of magnetic/H2O2, the removal rate of TP was 67.59% under the experimental conditions ofpH was 1, the dosage of Hydrogen peroxide solution （mass fraction of H2O230%） was 7.5 ml./L, the dosage of magnetic was 7.5 g/L, reaction temperature was 45℃for 2 h. The COD of the final effluent was 425mg/L, mass concentration of TP was 18.96 mg/L which met the request ofpretreatment.
