摘要
研究Fenton氧化技术处理偶氮染料活性艳红X-3B模拟废水的反应条件及处理效果,主要考察了Fe2+和H2O2的用量、温度以及废水的pH值等条件对色度和化学耗氧量(COD)去除率的影响。实验结果显示,Fenton氧化反应对废水色度和COD都有较好的去除效果,去除率分别为99.78%和94.34%。考察了不同光照条件Fenton试剂对废水的处理效果,结果表明光照能够加快Fenton反应速度、提高COD去除率。
The reaction condition and treatment efficiency of artificial dyeing wastewater of reactive brilliant red X-3 B were investigated by Fenton oxidation technique. The effects of the concentrations of Fe^2 ＋ and H2O2, temperature and pH of the wastewater on the removal rates of chroma and COD were studied. The results showed that the Fenton oxidation technique was effective for treatment of chroma and COD, and their removal rates were 99.78 % and 94.34 % respectively. The treatment under different illumination conditions indicated that illumination could hasten the reaction of Fenton and improve the removal rate of COD.
