摘　　要：从食品加工厂含盐污水处理车间的活性污泥中分离出对偶氮染料具有脱色活性的耐盐菌体,研究了不同pH值、脱色温度、接菌量以及装液量等条件对耐盐菌体降解酸性红B的影响,并设计正交实验,获得其降解模拟偶氮染料废水的最佳反应条件.研究结果表明,耐盐菌体TAS在35℃、pH为8、装液量为50mL及接菌量为8%(体积分数)的条件下,反应10h后对浓度为50mg.L-1的酸性红B模拟废水的脱色率达91%.Salt-tolerant bacteria with potential to decolorize azo dyes were isolated from saline food industry. Factors affecting the degradation of acid red B, including pH, investigated. Based on orthogonal design tests, the optimized conditions were 35℃, pH mL flasks. After 10 hours of treatment under these conditions, 91% of 50 mg.L^-1 acid the activated sludge of a wastewater treatment plant used for the temperature, inocula concentration and medium volume were 8, inocula concentration 8% and medium volume 50 mL in 150 red B was decolorized.
