| 摘 要： | 采用Fenton试剂对含分散红E-4B和活性艳兰KN-R染料组成的模拟印染废水进行氧化处理,考察了H2O2和Fe2＋浓度、pH、反应时间等因素对去除效果的影响。在H2O2投加量为5.0ml/L,Fe-SO4.7H2O投量为1.1g/L,pH为3,反应25min后静置5min的条件下,初始COD为700mg/L,色度为1200倍的废水的COD去除率可达到95%,脱色率达97%。结果表明,Fenton试剂对该废水可以起到很好的处理效果。

| Abstract: | Fenton reagent is used for treating the simulated printing and dyeing wastewater composed of disperse red E -4B and reactive blue KN -R. The effects of the H2O2and Fe2＋ concentration, pH and the reaction time on the removal rate are studied. When the dosages of H2O2 and FeSO4 7H2O are respectively at 5.0ml/L and 1. lg/L, with pH at 3, after 25 - minute reaction and 5 - minute standing time, for the original wastewater with COD at 700mg/L and chrominanee of 1200 times, the COD removal rate could be up to 95% and the decolorizing rate could be up to 97%. The results show that the Fenton reagent is quite effective in treating the wastewater . |
