| 摘 要： | 为考察长期运行条件下全程自养脱氮(CANON)反应器的运行效果,以人工配置无机高氨氮废水为进水,研究了连续流CANON反应器的运行稳定性.CANON反应器在控制内部温度为35℃±1℃,pH 7.39～8.01,水力停留时间3.7～5.1 h条件下,稳定运行超过1 a,短程硝化性能与厌氧氨氧化性能均获得稳定,平均TN去除负荷达到1.8 kg.(m3.d)-1,平均TN去除率为65.09%,最大TN去除率可达81.65%.低温冲击时,虽然ANAMMOX菌与AOB都会受到低温的抑制,但由于ANAMMOX菌对低温更加敏感,受到的抑制更加严重,因此造成NO2--N严重积累.温度恢复35℃后,CANON反应器性能很快恢复正常,短暂的低温冲击不会对CANON反应器稳定性构成显著影响;当经历超过50℃以上的高温冲击时,尽管AOB可在1周内恢复正常,但ANAMMOX菌的活性被完全破坏,使CANON反应器彻底崩溃,应予以避免.
