摘要：
染料废水具有高COD、高色度、高含盐量和低可生化性的特点。在前期研究的工艺（混凝+气浮+水解酸化+好氧）基础上，采用臭氧紫外工艺对好氧池出水进行深度处理。结果表明：臭氧紫外工艺协同深度处理染料废水的处理效果要明显好于臭氧和紫外单独处理染料废水时的效果；当pH为6~8时，臭氧质量浓度为50 mg/L，紫外线照射强度为40 μW/cm2，反应时间60 min情况下，COD的去除率为69.9%~72.1%，出水中COD为83.7~90.3 mg/L，达到纺织染整工业污染物排放标准（GB 4287—1992）（小于100 mg/L）。

Abstract:
Dye wastewater is characterized by high COD, high chroma, high salinity and low biodegradability, based on the preliminary research technology(coagulation+air flotation+anaerobic hydrolysis-acidification+oxic), a process combining ozone with UV has been used for the advanced treatment of effluent from aerobic tank. The results show that this combined process is feasible for the advanced treatment of dye wastewater. The treatment effect of it is significantly higher than that of using ozone and UV separately. A good removing rate ranging from 69.9% to 72.1%, and effluent COD 83.7-90.3 mg/L can be obtained, meeting the Discharge Standard of the Pollutants in Dyeing and Finishing of Textile Industry(GB 4287—1992)(below 100 mg/L), under the following conditions:pH is 6-8, ozone mass concentration 50 mg/L, UV intensity 40 μW/cm2 and reaction time 60 min.
