印染行业回用水水质执行标准探讨

Discussion on the Implementation Standard of Recycled Water Quality in Printing and Dyeing Industry

针对印染行业回用水水质缺乏统一指导标准的问题。在分析印染企业用水需求差异的基础上,参照城市污水再生利用分类分质回用的理念,提出在选用印染行业回用水质执行标准时,根据印染企业的产品、工艺以及回用水的用途,分类执行不同的水质指标和标准限值。

In view of the lack of unified guiding standards for the quality of recycled water in printing and dyeing industry. On the basis of analyzing the difference of water demand of printing and dyeing enterprises and referring to the concept of classification, quality and reuse of urban sewage recycling, it is proposed that different water quality indexes and standard limits should be implemented according to the products, processes and the use of recycled water in printing and dyeing industry when selecting the implementation standard of reuse water quality in printing and dyeing industry.
