印染废水脱色菌的选育及其生态特性的研究

Isolation and ecological characteristics of decolorizing bacteria from dyeing wastewater.

1 前言 印染工业是太湖地区小城镇的一大工业部门。随着乡镇企业的发展,印染废水排放量逐年增加,已成为严重污染区域水环境的重点污染源之一。近年国内外报道了利用微生物对印染废水进行脱色处理的可能性,为了多途径寻找适合于乡镇企业印染废水的经济、高效的生物处理技术,本研究针对目前印染废水生物处理中的菌种适应性和作用范围问题,选育出一批对多种染料有降解作用的“土著”脱色菌。

In general, bacteria hardly adapt to printing and dyeing wastewater, as the contaminants changed frequently. 17 strains of bacteria growing well in complex and changeful printing and dyeing wastewater were isolated, and their ecological characteristics were studied. They can be applied to the process of microbial decolorizaton.
