| 摘 要： | 本文以低温高氨氮废水为着眼点,通过不断地调节运行工况,探讨降温过程中全程自养脱氮(CANON)工艺的运行特征,以探索出低温环境下进水NH_4~+-N浓度较高时,CANON工艺获得稳定短程硝化和良好脱氮效果的方法.结果表明:①相较于直接将生物膜CANON反应器的温度条件由中温转变为低温(30℃±1℃→19℃),逐步降温驯化更有利于脱氮功能菌适应低温环境,且每次降温的幅度应尽量减小,同时还应配合运行工况的调节;②温度经25 d逐步降低至19℃左右,18 d后又继续降至15℃左右,NH_4~+-N和TN去除率均能分别长期稳定在90%、70%以上,甚至当温度下降至12℃时,TN去除率与去除负荷仍能分别达到72. 52%、0. 78 kg·(m~3·d)~(-1);③降温过程中驯化生物膜CANON污泥时,应优先考虑短程硝化控制.可通过维持一定的剩余NH_4~+-N浓度并严格控制DO浓度,以抑制NOB的活性,从而获得稳定的短程硝化效果.
