蒽醌-2,6-二磺酸(AQDS)强化厌氧降解直接蓝15
|
摘要
研究蒽醌-2,6-二磺酸(AQDS)强化厌氧降解典型偶氮染料直接蓝15,重点考察AQDS浓度、共基质和厌氧反应阶段对直接蓝15厌氧去除特性的影响。AQDS能够有效促进直接蓝15厌氧降解,其最佳浓度约为1 mmol/L。当以淀粉、胰蛋白胨或淀粉/胰蛋白胨作为共代谢基质时,胰蛋白胨条件下直接蓝15的色度去除效果与速率最佳。水解酸化和全程厌氧反应均能有效去除直接蓝15,说明水解酸化反应是厌氧降解直接蓝15的主要反应过程。因此,将厌氧反应控制在水解酸化阶段即能实现染料的有效降解。
Enhanced anaerobic degradation of typical azo dye of direct blue 15 by anthraquinone-2,6-disulfonate(AQDS) was investigated, with focusing on the effects of AQDS concentrations, co-metabolic substrates and anaerobic stages. AQDS promoted anaerobic decolourization of direct blue 15, with the optimized dosage concentration of approximately(1 mmol/L). Among co-metabolic substrates of starch, tryptone and starch/tryptone, both decolourization efficiency and degradation rate of direct blue 15 were the highest with tryptone as co-metabolic substance. Under conditions of hydrolysis/acidification or the whole anaerobic process, decolourization of direct blue 15 were both efficient, indicating that hydrolysis/acidification played an important role in the decolorization of direct blue 15. Therefore, for decolorization of dye wastewater, controlling anaerobic reaction at the hydrolysis/acidification stage could be adequate.
