摘　　要：采用Fenton试剂对甲醛废水进行氧化处理,考察了H2O2浓度、Fe2+浓度、pH值、反应时间等因素对处理效果的影响。在H2O2投加量为4.5 ml/L,n(H2O2):n(Fe2+)=4,pH值为3,反应30 min后,静置5 min的条件下,废水中甲醛去除率和COD去除率分别达到89%、82%。结果表明,Fenton试剂对甲醛废水可以取到很好的处理效果。Fenton reagent is used for treating H202 and Fe2 ~ , pH value, reaction time and the dosages of H202 is around 4.5 ml/L,n（ min and ended the reaction after stewing 5 wastewater are respectively 89% ,82%. The aldehyde wastewater. formaldehyde wastewater, the effects of the concentration of other factors on the treatment effect are investigated. When n2 02 ） ： n （ Fe2 ＋ ） = 4, pH value is 3, the stirring time is 30 rain, formaldehyde removal rate and COD removal rate in result showe that fenton reagent had good effect for the form-aldehyde wastewater.
