稀土催化双氧水氧化耦合处理染料中间体废水研究(I)

Study on rare earth inducing H_2O_2 oxidative coupling for treatment of dye-intermediator waste water

探讨了稀土配合双氧水处理蒽醌类染料废水时的影响因素与具体工艺参数。实验结果表明 ,在有稀土的双氧水处理体系中 ,底物的氧化与新生态有机物的耦合是共存的 ;过氧化氢与稀土的最佳加入量因废水的初始浓度而定 ;反应温度为 60℃ ,HRT为 75 min。在相同的条件下 ,同 Fenton试剂相比 ,该法氧化剂需要量少 。

The radical factors were discussed in the process of treating dye\|intermediator wastewater with mixed\|rare earthes and H\-2O\-2 . The results indicate the oxidation of reactive materials and coupling of products are concomitants. The best quantity of H\-2O\-2 or mixed\|rare earthes is based on the original concentration of waste water , but the best technical parameters are: temperature is \{60 ℃\}, HRT is 75 min . The method is economical and high effective.\;
