生物法处理印染废水的研究进展

Research Progress in Biological Treatment of Printing and Dyeing Wastewater

印染废水是一类有机物含量高、色度高、生化性能差的难降解废水。生物法是利用微生物降解代谢有机物为无机物来处理废水,通过人工创造适于微生物生存和繁殖的环境,使之大量繁殖,以提高其氧化分解有机物的效率。主要介绍了膜生物反应器、固定化微生物、SBR法、微生物絮凝剂等技术在印染废水处理方面的应用现状,并对今后的研究方向提出了建议。

Printing and dyeing wastewater is a kind of refractory wastewater, which has high organic matter content, high chromaticity and poor biochemical. The biological method is to use microbes to degrade organic matter in the wastewater. Creating suitable environment for microbial survival and reproduction can make the microorganism breed largely, which will improve the oxidative decomposition effect of the organic matter. In this paper, application of membrane biology technology, immobilized microorganism and SBR method, microbial flocculants in printing and dyeing wastewater treatment were introduced, and the future research direction was orooosed.
