印染废水深度处理研究及应用进展

Research and Application Progress of Advanced Treatment of Dyeing Wastewater

由于印染废水成分复杂、可生化性差,常规"预处理+生化处理"难以使尾水达标排放,需添加深度处理单元进行进一步处理。对常用于印染废水深度处理的技术进行了分类阐述,介绍了各技术的优缺点。通过实例对各技术在工程中的研究及应用进行归纳,提出目前印染废水深度处理中存在的问题,为今后的研究及应用方向提供建议。

Due to complex composition and poor biodegradability of printing and dyeing wastewater,the tail water of conventional"pretreatment+biochemical treatment"technology is difficult to meet the standard discharge,and further processing units need to be added for further treatment.Technologies commonly used for advanced treatment of printing and dyeing wastewater are classified.Advantages and disadvantages of each technology are also introduced.Research and application of each technology in engineering are summarized through examples,problems existing in advanced treatment of printing and dyeing wastewater are put forward,and suggestions for future research and application directions are provided.
