摘要:

从化学键能出发,着重探讨了臭氧氧化法、Fenton氧化法处理硒冶炼废水中有机污染物的机理,并对高级氧化法进行优化组合。实验结果表明,单独使用臭氧处理废水,在酸性条件下受酯化反应的影响,加入双氧水能抑制酯化反应的进行。臭氧/H2O2+Fenton氧化法是最好的联合技术,CODCr去除率可达到88%。

Abstract:

Procee ding from chemical bond energy,the treatment mechanism of organic pollutants contained in selenium smelting wastewater by ozonation and Fenton oxidation is discussed emphatically. The optimized combination of the advanced oxidation is carried out. The experimental results show that when the wastewater is treated with ozone solely,it is affected by esterification reaction,under acidic conditions. Adding H2O2 to the reaction could effectively restrain esterification. However O3/H2O2+Fenton oxidation is regarded as the best united technologies.Its CODCr removing rate reaches 88%.

Key words: advanced oxidation process, ozonation, Fenton oxidation, selenium, smelting wastewater
