臭氧深度处理技术在印染废水处理中的应用

Application of advanced ozone treatment technology in printing and dyeing wastewater treatment

随着印染废水纺织染整工业水污染物排放标准的日益严格,采用混凝法、次氯酸钠脱色法等常规的深度处理方法处理印染废水生化出水达标难度较大,因此,寻求一种高效环保的处理技术是形势所趋。本文针对棉花散纤维印染废水实际案例,通过臭氧深度处理技术应用到印染废水生化出水中,最终出水稳定色度等各项目指标稳定达标。

With the increasingly stringent discharge of water pollutants in the textile dyeing and finishing industry of printing and dyeing wastewater,it is difficult to treat the biochemical effluent of printing and dyeing wastewater with conventional in-depth treatment methods such as coagulation method and sodium hypochlorite decolorization method.Processing technology is the trend.In this paper,the actual cases of cotton loose fiber printing and dyeing wastewater are applied to the biochemical effluent of printing and dyeing wastewater through the advanced ozone treatment technology.The final effluent stability chroma and other project indicators are stable and meet the standards.
