摘　　要：采用电子束辐照对印染废水处理工艺中主要阶段的废水进行了处理。并根据色度学原理,利用分光光度法测定水体的色度。经电子束辐照后,物化–生化处理后的水样在200kGy时,色度可低至10度以下,脱色率达90%,目视比色时几乎与光学纯水无差别。经电子束辐照后,物化处理后的水样在100k Gy时,色度降至原液色度的46%;200 kGy时,色度降至50度左右,为原液色度的18%。电子束辐照对传统印染工艺主要阶段的废水脱色均有明显的效果,将电子束辐照与印染废水传统处理工艺相结合,可实现对印染废水色度的深度处理。The effect of electron-beam irradiation on the colority of the wastewater extracted by different methods in traditional physicochemical–biochemical processes was studied. Moreover, spectrophotometry was employed to determine the water colority of printing-dyeing wastewater. The results showed that the colority of the physicochemical–biochemical-treated wastewater was less than 10 Hazen at 200 kGy with up to 90% decolorization rate and that it was difficult to distinguish from pure water. For the physicochemical-treated wastewater, the decolorization rate was 46% at 100 kGy and the colority was about 50 Hazen at 200 kGy with up to 82% decolorization rate. Electron-beam irradiation had a positive effect on different kinds of dyeing wastewater. A combined treatment of electron-beam irradiation and a traditional physicochemical–biochemical process is recommended for the advanced treatment of dyeing wastewater.
