摘要
采用铁炭微电解～Fenton试剂氧化法预处理广灭灵和丙草胺废水（简称废水），考察了H2O2加入量、高浓度废水COD对废水处理效果的影响，进行了连续流废水处理实验。实验结果表明：Fenton试剂氧化反应的废水处理效果明显好于铁炭微电解反应；铁炭微电解对COD的去除率可达60．6％，Fenton试剂氧化反应后COD的总去除率可达72．3％；连续流废水处理效果差于静态实验。处理后，低浓度废水的BOD，／COD从0．28～0．32增至0．47，高浓度废水的BOD，／COD从0．39增至0．47。
The wastewater from clomazone and pretilachlor production was pretreated by Fe-C microelectrolysis -Fenton reagent oxidation process. The effects of H2O2 dosage and high wastewater COD were studied in continuous flow treatment. The experimental results indicate that： The treatment effect by Fenton reagent oxidation with 72. 3% of COD removal rate is better than that by microelectrolysis with 60.6% of COD removal rate; The effect of continuous flow treatment is worse than that of static treatment. After pretreated, the BOD5/COD value of the low concentration wastewater is increased from 0.28 - 0.32 to 0.47, and that of the high concentration wastewater is increased from 0.39 to 0.47.
