摘　　要：从某印染废水的活性污泥中富集了一个能够高效降解酸性大红GR的菌群。研究结果表明,该菌群在15h内几乎将100mg/L的酸性大红完全脱色。该菌群在偏碱性环境下的脱色效果大于酸性环境,并表现出高效广谱染料脱色降解特性。当温度在10°C～30°C之间时,脱色率随温度的递增而增大,在30°C时脱色率达到最大。A bacteria group capable of degrading acid scarlet GR was enriched from the activated sludge of a printing and dyeing wastewater.The results showed that the bacteria almost completely decolorized acid scarlet at 100 mg/L within 15h.The decolorizing effect of the bacteria group in the alkaline environment was higher than that in the acidic environment,and showed the characteristics of decolorization and degradation of the dyes with high efficiency and broad spectrum.When the temperature is between 10℃and 30℃,the decolorization rate increases with the increase of temperature,and reaches the maximum at 30℃.
