摘要：

采用Fenton法进行了反渗透浓缩液的处理实验,研究表明:单独使用UV不能有效去除废水中的有机物,也不能去除色度;采用UV+H₂O₂+铁粉工艺和三维电极+铁粉工艺实验时,在pH=3,废水中的COD的去除率可达30%以上,同时有很好的脱色效果;而且三维电极+铁粉工艺随着时间的推移,其处理效果有所增加。通过实验确定了最佳处理参数,同时对其反应机理进行了探讨。

Abstract:

Fenton process has been used for treating the concentrated solution of reverse osmosis.It shows that using UV singly could not remove the organisms from wastewater and chroma efficiently.But using the UV,UV+ H₂O₂+Fe powder and three-dimensional electrode + Fe powder process,when its pH = 3,the COD removal rate in wastewater can reach 30%,and quite good decolorization result can be obtained.With the time going on,the treatment effect can be even better.Based on experiments,the optimal treatment parameters have been found.And its reaction mechanisms have been discussed

Key words: advanced oxidation technology, Fenton process, concentrated solution of reverse osmosis
