印染废水处理技术研究进展

Advances in dyeing and printing wastewater treatment technologies

介绍了各种印染废水处理的方法:物理化学法、化学法及生物技术法,分析了各类技术方法的机制、处理效果及其优缺点。根据印染废水特性,采用不同处理方法的组合工艺技术,可实现对印染废水的彻底处理。以生物技术法为主体,辅以物理化学处理的组合处理工艺已逐渐成为目前印染废水处理的主流工艺。

This paper introduces the current status and developments of the typical treatment technologies of dyeing and printing wastewater （DPW）, including physical-chemical, chemical, and microbial processes with focuses on the mechanism, result of treatment, and merits and drawbacks of each process. According to the characteristics of the dyeing and printing wastewater, thorough treatment of the wastewater can be accomplished through the hybrid of different processes. The hybrid method based on microbial process has gradually become the main technology for the treatment of the dyeing and printing wastewater.
