| 摘 要： | 分别采用UV-TiO2-O3、Fenton和UV-O3-Fenton这3种不同的氧化体系对高含量难生化降解染料废水进行预处理,并对其处理效果和反应机理进行了讨论。结果表明,UV-O3-Fenton氧化体系对废水的色度、COD去除及可生化性的改善均优于UV-TiO2-O3和Fenton氧化体系。当紫外灯功率为580 W、pH为4.5、体积分数为30%的H2O2投加量0.6 mL·L-1,n(H2O2)/n(O3)=0.85、n(H2O2)/n(Fe2+)=25:1,臭氧投加量为150 mg·L-1,t=200 min时,UV-O3-Fenton氧化体系对废水的色度、COD去除率及BOD5/COD分别可达100%、84.72%和0.72。 |
