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.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 intennodiates 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 rote 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.
