  • 摘要: 全程自养脱氮(CANON)工艺在110 d时,总氮去除负荷(NRR)达到了1.8 kg N/(m3·d)。在高溶解氧(DO)的条件下,CANON工艺脱稳失活,脱氮性能急剧下降,ANAMMOX菌受到抑制。采取减少曝气量,降低反应器中的DO,可以有效恢复CANON工艺的脱氮性能。在第327天时,进水氨氮浓度高达1 245.5 mg/L,氨氮和总氮去除效率分别达到98.4%和80.3%,而NRR高达了1 kg N/(m3·d)。此后,CANON工艺脱氮效果较为稳定,表明CANON工艺恢复效果明显。SEM分析表明,颗粒污泥表面附着大量的短杆状细菌,细菌之间联系紧密,部分颗粒污泥表面呈现网状结构,细菌之间通过丝状物联系形成颗粒污泥。能谱分析表明,颗粒污泥表面含有O、Na、P、Fe、Ca、C和Si等元素。
