印染废水处理工艺进展

Development of Printing and Dyeing Wastewater Treatment Processes

印染废水是一种有机物含量高,色度高,生化性能差的难降解废水。介绍了近几年来经工程实践证明较成熟、处理效果相对较理想的典型的印染废水处理工艺,给出了各工艺的流程图及处理效果,并对其进行了初步的经济比较。

Printing and dyeing wastewater is a kind of wastewater with high content of organic matters, high colority and poor biochemical performance and is hard to degrade. Typical printing and dyeing wastewater treatment processes which have been proven through engineering practice in recent years to be relatively mature and with relatively ideal treatment results are introduced, with the flow diagrams of the processes as well as the treatment results given and preliminary economic comparisons thereof made.
