| Abstract: | 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 3 min,standing for 15 min.The decolorizing rate could reach 93.88% at the optimal decolorizing condition.At the same time,th... |
