摘要 本文研究了过氧化氢在铁、锰两种金属离子共同作用下的催化体系对含有茜素红染料废水的脱色和降解作用。结果表明:Fe2+/Mn2+/H2O2体系在pH5~6时对该染料废水的脱色和降解作用明显,脱色率和降解率均达到80%以上,COD去除率大于70%。处理后的废水值接近中性,可以直接排放。 In this paper, a new method of decolorization and degradation of dye wastewater containing alizarine red has been studied. In this method, the oxide H_2O_2 acted with two catalysts Fe^(2+) and Mn^(2+), the mass ratio of them were H_2O_2∶Fe^(2+)=10∶1 and H_2O_2∶Mn^(2+) 6∶1. The result indicated that the action of decolorization and degradation were obvious in Fe^(2+)/Mn^(2+)/H_2O_2 system under the condition of pH5~6. The decoloration rate and degradation rate were all over 80%, COD removal rate, over 70%. The treated waste water can be drained away directly for its pH was neutral.
