印染废水处理技术研究进展

Progress research on treatment technology of printing and dyeing wastewater

纺织印染技术的发展导致印染废水的成分日趋复杂,无形中增加了废水处理的难度。目前,废水处理包括物理处理、化学处理、生物处理等技术。从处理机制、效果和优缺点方面进行了分析。同时,依据纺织印染废水的特点,采用不同处理方法和工艺技术,实现对纺织印染废水的彻底处理。结果显示,以生物处理技术为核心,物理、化学处理技术为辅助的综合废水处理方案,非常适合纺织印染行业进行废水处理。

The development of textile printing and dyeing technology which make complex of composition of printing and dyeing wastewater increasingly,and increase the difficulty of the wastewater treatment technology.At present,the wastewater treatment technology includes physical treatment,chemical treatment,biological treatment and so on.The wastewater treatment technology from mechanism,effect,advantages and disadvantages was analyzed.At the same time,textile printing and dyeing wastewater could be completely treated by according to the characteristics of textile printing and dyeing wastewater,using different treat?ment method and technology.The research results showed that the biological treatment technology was the core technology,the physical and chemical technology was the assistive technology,which was very suitable for printing and dyeing wastewater treatment.
