摘　　要：从活性污泥中筛选出的一株微生物絮凝剂产生菌,在优化培养条件下所产微生物絮凝剂命名为M-127。将M-127用于染料废水脱色。实验结果表明,废水脱色的最佳条件是:100 mL染料废水中加入0.2 mL M-127和2.0 mL CaCl2、体系pH值6.0,200 r/min搅拌1 min,60 r/min搅拌3 min,静置15 min。M-127对染料废水的脱色率达到93.88%。同时,还研究了M-127在最佳条件下的脱色动力学,并得到了脱色动力学经验方程。A new kind of flocculant-producing bacteria which obtained from activated sludge could produce microbial flocculant（M-127） under the optimal culture conditions. M-127 was used to treat dyeing wastewater. The results showed that the optimum decolorizing conditions were： 0.2 mL M-127 and 2.0 mL CaCl2 in 100 mL dyeing wastewater,pH value 6.0,stirring at 200 r/min for 1 min and 60 r/min for 3min,standing for 15 rain. The decolorizing rate could reach 93.88% at the optimal decolorizing condition. At the same time,the decolorizing dynamics of the M-127 under the optimal condition was also investigated and the decolorizing dynamic empirical equation was obtained.
