印染废水处理工艺

Printing and Dyeing Wastewater Treatment Process

印染行业用水量大,生产排放的废水量也很大,这些废水如果未进行有效处理,不仅造成资源的浪费,而且对环境造成了一定的污染。文章介绍当前印染行业的处理工艺,包括物化法、生化法以及膜分离技术法,可为工程设计人员提供一定的工程实践经验及参考价值。

The printing and dyeing industry consumes a large amount of water,and the amount of wastewater discharged from production is also large.If these wastewater are not treated effectively,it will not only cause waste of resources,but also cause certain pollution to the environment.This paper introduces the current treatment technology of printing and dyeing industry,including physicochemical method,biochemical method and membrane separation technology method,which can provide engineering designers with certain engineering practice experience and reference value.
