对三种不同初始浓度的罗丹明B废水进行Fenton氧化降解工艺条件及降解历程进行研究。结果显示：当[H2O2]：[Fe^2＋]（摩尔比）=3．26的时候，COD去除效果最好，随着[Fe^2＋]的投加量增加，废水会变成铁红色，同时沉淀物增加：COD分别为200，300和800mg／L的3种不同浓度的废水，[H202]投加量分别为0．5，0．9，3．5mL，废水的初始pH=3的时候，COD的去除率最好。

Degradation conditions and processes of Rhodmine B using Fenton（Fe^2＋/H2O2） reactions was investigated in three different conditions. The results showed that the COD removing rate was the largest at [H2O2] ： [FeZ＋]（molar ratio）=3.26. With the dosage increasing, the wastewater became red and more deposits generated. The COD removing rate was the largest at pH=3, dosages of [H2O2]=0.5, 0.9 and 3.5 mL for three different concentrations（200, 300 and 800 mg/L）wastewater.
