摘    要:设计了微波强化Fenton氧化处理系统,以难降解的邻氨基苯甲酸生产废水为研究对象,考察初始pH,微波辐射时间,微波辐射功率,ρ(H2O2),ρ(Fe2+)及催化剂投加量对降解效果的影响,并分析了各影响因子的作用机理和综合反应机理,确定了应用该系统的关键控制步骤. 结果表明,采用微波强化Fenton氧化处理邻氨基苯甲酸生产废水的最佳操作条件:pH为3,微波辐射时间为6 min,微波辐射功率为850 W,ρ(H2O2)为50 mg/L,ρ(Fe2+)为10 mg/L,催化剂投加量为60 g/L. 最佳操作条件下,出水中CODCr,色度和邻氨基苯甲酸的去除率分别为80%,85%和90%. 水处理费用约为4.2元/t. 

关 键 词:邻氨基苯甲酸废水  微波强化  Fenton  氧化
