| Abstract: | Bacterium with potential to decolorize azo dyes was isolated from lab scale modified anaerobic-anoxic-aerobic(AAO) process for treating printing and dyeing wastewater.Factors affecting the decolorization of reactive black 5,including pH,temperature,inocula concentration and medium volume were discussed.Based on orthogonal design test,the optimized conditions were 30 ℃,pH 6,inocula concentration 8%(V/V) and medium volume 100 mL in 250 mL flasks.After 25 h treatment under the conditions,90.48% of 50 mg/L reactive black 5 was decolorized. |
