摘要
印染废水是一种水质水量变化大、有机物含量高、可生化性差、COD高、色度高的难降解废水。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。根据印染废水的水质特点,通过对不同处理方法进行组合,辅以微生物高效强化技术,是今后印染废水处理的发展方向。
The dyeing and printing wastewater(DPW) is difficult to be degraded, featured with great change in quality and quantity, high - concentration of organic contaminants, low BOD/COD value, and high chromaticity. This paper introduced the typical DPW treatment technologies, including physical -chemical, chemical, and microbial processes in terms of their current status and develop- ments, degradation mechanism, treatment efficiency, and merits and draw backs of each process. Fi- nally it pointed out that specific combination of treatment process, supplemented with microbial en- hancement technology, should be pursued according to the characteristic of the DPW.
