The main objective of this work is to reduce the chemical oxygen demand (COD) and color of the effluent containing reactive textile dye by microbial method. Anaerobic digestion has the potential to break down complex refractory organic compounds so that they may be further degraded aerobically or to completely mineralize them. An anaerobic digestion technique was applied to synthetic reactive red 2 dye cotton textile effluent aiming at the dye degradation. Halophilic and halotolerant bacterial culture Halomonas variabilis and Halomonas glaciei were used for degradation in batch-mode static condition. The temperature was kept constant at 30°C using CO(2) incubator. Maximum degradation was achieved within 144 h of experimental run. Degradation studies were made by determining COD and biochemical oxygen demand (BOD). Statistical analysis showed that the BOD and COD reduction rate were optimal in the concentration of 1297 mg L(-1) for the time duration of nearly 100 h.
本工作的主要目的是通过微生物方法降低含有活性纺织染料的废水的化学需氧量 (COD) 和色度。厌氧消化具有分解复杂难降解有机化合物的潜力，以便进一步好氧降解或完全矿化它们。采用厌氧消化技术处理合成活性红 2 染料棉纺织废水，以实现染料降解。嗜盐菌和耐盐菌培养物 Halomonas variabilis 和 Halomonas glaciei 用于分批静态条件下的降解。使用 CO(2)孵育箱将温度保持在 30°C 恒定。在实验运行 144 小时内达到最大降解。通过测定 COD 和生化需氧量 (BOD) 进行降解研究。统计分析表明，在近 100 小时的时间内，在 1297 mg/L 的浓度下，BOD 和 COD 的去除率最佳。
