  • 摘要: 对一套处理效率高、运行稳定的UASB-生物膜厌氧氨氧化反应器进行了温度变化的实验研究。实验结果表明,厌氧氨氧化反应对温度变化比较敏感,温度从31℃下降到17℃后,反应器内的厌氧氨氧化活性受到显著抑制,氨氮、亚硝酸盐氮和总氮的平均去除率迅速从97.0%、94.1%、86.0%下降为46.2%、41.8%、35.5%。当历时2个月反应器温度逐渐从17℃升高到31℃时,反应器内高效厌氧氨氧化活性逐渐得到恢复。反应器在17℃停止运行2个月后,直接升温至31℃再次运行,仅仅需要17 d时间,反应器内厌氧氨氧化高活性就得到恢复,氨氮、亚硝酸盐氮和总氮的最高去除率达到99.4%、90.6%和85.0%。厌氧氨氧化反应的最佳温度应为31℃。
    Abstract: The temperature influence on the anaerobic ammonia oxidation was observed in a set of operated well UASB-biofilm anaerobic ammonia oxidation reactor. The experimental results show that anaerobic ammonia oxidation reaction is sensitive to temperature change. When the temperature of reactor dropped from 31℃ to 17℃ quickly,the anaerobic ammonia oxidation activity inside the reactor was significantly restrained and the average removal efficiencies of NH4+-N, NO2--N and TN dropped from 97.0%, 94.1% and 86% to 46.2%, 41.8% and 35.5% respectively. When the temperature in reactor arose up to 31℃ in two months, the anaerobic ammonia oxidation activity recovered slowly; when the reactor after stayed for 2 months at 17℃ was restarted up at 31℃ directly, the high anaerobic ammonia oxidation activity can recover quickly in 17 days and the highest removal efficiency of NH4+-N, NO2--N and TN reached 99.4%,90.6% and 85.0%, respectively. The optimum temperature of anaerobic ammonia oxidation should be 31℃.
