摘　　要：采用UV/H2O2/草酸铁络合物氧化工艺处理染料活性艳蓝K-3R模拟废水,考察了不同反应条件对脱色效果的影响。试验结果表明:UV/H2O2/草酸铁络合物氧化工艺对活性艳蓝K-3R具有较好的脱色效果,pH值,H2O2,Fe3+,C2O42-的浓度对脱色效果有较大影响。对7种不同类型的染料模拟废水的UV/H2O2/草酸铁络合物氧化工艺脱色实验结果表明,染料结构对于脱色效果也有很大影响,偶氮染料比蒽醌染料更易于脱色。UV/H2O2/Ferric oxalate complexes process was used to treat simulated wastewater of Reactive Brilliant Blue K- 3R. The affecting factors were preliminarily investigated. The results show that the UV/H2O2/Ferric oxalate complexes process can make the dyeing wastewater decolor rapidly. The pH, the concentration of H2O2, Fe^3＋ and C2O4^2- play a significant role in the UV/H2O2/Ferric oxalate complexes Process. The test results of simulated wastewater of seven different kinds of dyes show that the structure can affect the degradation degree of dyes and the azo dyes degrade easier than the anthraquinone dyes.
