| 摘 要： | 研究UV/Fenton氧化法中各个因素对降解水中苯酚的影响,确定UV/Fenton法处理苯酚废水的工艺条件。保持UV/Fenton体系的基准条件不变,通过改变H2O2浓度、n(Fe2+)∶n(H2O2)、废水初始pH值等实验条件,考察这些因素对UV/Fenton法处理苯酚废水效果的影响。结果表明:UV/Fen-ton氧化法对苯酚废水有较好的去除效果和较高的反应速率。当废水初始pH值为3.0时,经30 min的反应,苯酚去除率达到99%,COD去除率达到86%。但是苯酚废水COD去除率滞后于苯酚去除率。UV/Fenton法能够在较短的时间内去除苯酚和COD,H2O2浓度、n(Fe2+)∶n(H2O2)对处理效果影响较大,H2O2浓度决定苯酚去除率和COD去除率,而n(Fe2+)∶n(H2O2)是影响降解速率的主导因素。
