| 摘 要： | 采用微波辐射诱导Fenton氧化工艺处理对硝基氯苯模拟废水。考察了H2O2用量、Fe2+用量、溶液pH、微波辐射时间、微波功率对降解效果的影响;比较了微波诱导Fenton氧化法和单纯的Fenton氧化法对对硝基氯苯的去除效果。结果表明,微波辐射不仅可以提高对硝基氯苯的去除效率,还可促进对硝基氯苯的矿质化,大大提高COD去除率,并缩短反应时间。微波诱导Fenton氧化降解对硝基氯苯的适宜工艺条件为:H2O2和Fe2+用量分别为3.0g/L和160mg/L、pH为3、微波功率为800W、微波辐射时间为10min。在此工艺条件下,对硝基氯苯和COD的去除率分别可达98.9%和90.8%。
