摘要

本文研究185nmUV加H

去除工业废水中的色度.实验结果表明:185nmUV能使水发生均裂反应

产生·OH、·H和e

(水合电子)等活性中间体

对废水的色度有一定的去除作用;对185nmUV加H

对废水的色度有很好的去除效果

而且H

在紫外线的作用下也可以生成·OH

与单独使用185nmUV相比

降解速率可以提高10~20倍.因此脱色效果好

脱色速度快

适合多种色料

处理后结果色度均能达到国家一级以上的排放标准.本文研究的185nmUV+H

方法

工艺简单、操作方便、脱色快捷效果好

可广泛应用于各种场合的各种色度的脱除.

Abstract

The removal of chroma of Industrial wastewater is investigated with method of combination of 185nmUV rays and H

.The following results are obtained:The chroma of Industrial wastewater can be removed by lots of intermediates produced by water molecules dissociation under the irradiation of 185nm UV rays

such as ·OH

·H and e

(hydrated electrons).If a little amount of H

is added

the removal rate of chroma of industrial wastewater can be 10~20 times higher than that only using UV rays because H

can also be decomposed to ·OH under irradiation of UV rays.The effluent can be discharged meeting th

e requirements of GB4287-92.So this method has many advantages of high efficiency

fastness

simpleness

easy operation and universal use to many kinds of industrial wastewaters.
