| 摘 要： | 本文研究185nmUV加H2O2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eaq(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H2O2对废水的色度有很好的去除效果,而且H2O2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+H2O2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 H2O2.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 eaq(hydrated electrons).If a little amount of H2O2 is added,the removal rate of chroma of industrial wastewater can be 10~20 times higher than that only using UV rays because H2O2 can also be decomposed to ·OH under irradiation of UV rays.The effluent can be discharged meeting the 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. |
