Abstract: The quality and quantity of dyeing and printing wastewater have changed significantly because of the development of dyeing and printing industry. The current situation of dyeing and printing wastewater in China is analyzed. The improvement of biotechnology，such as aerobic biotechnology，anaerobic biotechnology and anaerobic-aerobic biotechnology for dyeing and printing wastewater treatment is presented. The progress of new biotechnology，such as bio-augmented and immobilized microorganism is reviewed.

摘要： 随着我国印染行业的发展，印染废水的水质和水量都发生了很大变化。本文评述了我国印染废水水质和水量的现状，分析了印染废水处理中常规生物处理技术（好氧处理技术、厌氧处理技术和厌氧-好氧处理技术）的发展，并阐述了印染废水处理中两种新型生物处理技术（生物强化技术和固定化微生物技术）的研究进展。
