Abstract:

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.
