染料在纺织领域使用较为广泛,对环境的污染也最为严重,因此纺织品污水处理方法研究是绿色工业生产中的一个重要课题。使用价格低廉、易于培养的活性污泥细菌对染料进行生物降解,并通过细胞毒性试验、小鼠全身毒性试验、化学需氧量（COD）测试、分光光度法测试和红外分析法测试来表征染料降解的程度。结果表明：活性污泥对5种染料（4种酸性染料和1种碱性染料）的降解效果明显,降解后COD值明显下降,染料的去除率为71.4%～76.1%;分光光度法测试的染料平均降解效率为90.6%。

Dyes are widely used in textile field,resulting in the serious environmental pollution.Therefore,to investigate the textile wastewater treatment method is the need of green industrial production.We report the use of activated sludge bacteria,which is cheap and easy to be cultured,for biological degradation of dyes.The degree of dye degradation is characterized by cell toxicity,mouse systemic toxicity test,chemical oxygen demand,spectrophotometry and infrared analysis.The results show that the degradation of activated sludge on five kinds of dyes is effective,that is,after degradation,COD values from treated solutions decrease obviously,dye removal rate is 71.4%~76.1% and dye degradation average efficiency is 90.6%.
