Abstract

采用零价铁(ZVI)/Fe2+/H2O2类Fenton法深度处理造纸法烟草薄片废水(二级生化出水),探讨了反应时间、初始pH、Fe2+浓度、H2O2浓度和ZVI质量浓度对COD和色度去除效果的影响.结果表明,当反应时间为60 min、初始pH为5.0、Fe2+浓度为1.0 mmol/L、ZVI质量浓度为2.0 g/L、H2O2浓度10 mmol/L时,处理后色度为84 C.U.、脱色率为95.5％;COD为73 mg/L,COD去除率为80.4％.与传统Fenton法对比发现,ZVI/Fe2+/H2O2类Fenton法具有可在弱酸性条件下(pH=5.0)使用、总铁需求量少(减少26％)和产泥量少(减少2/3左右)的优点.
