摘要
采用F en ton试剂-微电解联用预处理一种高浓度硝基苯类化工废水.试验结果表明:在[H2O2]=0.1 m o l.L-1,[F e2+]=0.01 m o l.L-1,反应时间60 m in,反应体系pH为3.0时,经F en ton法预处理后废水中硝基苯类化合物去除率达到44.6%,CODC r去除率达到48.1%,而经F en ton试剂-微电解联用预处理后,硝基苯类化合物去除率可达到96.8%,CODC r总去除率可达到67.2%.
In this paper, Fenton reagent and micro-electrolysis technology are used to pre-treat wastewater containing higher concentration of nitrobenzene. Experiments show the removal efficiency of nitrobenzene and CODe, by Fenton reagent can reach 44.6% and 48.1% respectively in the following conditiorr： [H2O2] = 0.1 mol·L^-1, [Fe^2＋] = 0.01 mol·L^-1, reaction time = 60 min and pH =3.0. The total removal efficiency of nitrobenzene is 96.8% and that of CODCr is 67.2% respectively.
