Exploiting a new world for textile dyeing and printing enterprises by energy-saving and emission-reduction wastewater treatment

印染废水是难处理的工业废水之一,其排放量大、有机污染物含量高、成分复杂、色泽深、难生物降解,通常的处理方法很难达到环保和回用的要求。针对纺织印染废水排放治理当务之急,分析了各类纺织印染废水的特征,阐述了印染废水处理工艺流程及选择,研究了印染废水治理方法,指出了行业治理印染废水、节能减排的发展趋势。

Dyeing and printing wastewater was one of the difficult treatment industrial wastewater, which was of large emission, high organic pollutants content, complex composition, deep color and hard biodegrade. It was difficult to reach the environmental and recycle requirement using conventional treatment method. Aiming at the imperative of textile dyeing and finishing wastewater treatment, the characteristics of various textile dyeing and printing wastewater were analyzed. The treating process and selection were described and the treating methods were also investigated. Finally, the development tendencies of treating wastewater and energy-saving and emission-reduction were pointing out.
