The characteristics and components of printing and dyeing wastewater as well as the ordinary secondary treatment process were briefly introduced.Taking advanced treatment process as the research object,different methods for advanced treatment of printing and dyeing wastewater and their characteristics and application status were summarized.Currently,the quality of advanced treated printing and dyeing wastewater could reach the standard of wastewater discharge and reclaimed water reuse; however,there still existed many problems when those mentioned methods were used in actual engineering.Finally,three development directions in the future:optimizing the combination of different processes,developing quality-based recycling technology,and coupling productive process with wastewater treatment,were pointed out.%简要介绍了印染废水的特点、组成以及常规的二级处理工艺,再以深度处理工艺为主要研究对象,综述了应用于印染废水深度处理的各种方法、特点和应用情况.目前,经深度处理后的印染废水可以达到排放和回用标准,但各种方法在工程应用中仍存在很多问题.提出了优化组合工艺、开发分质回用技术和耦合生产过程与废水处理3个发展方向.
