近年来,异养硝化-好氧反硝化菌的发现打破了传统硝化反硝化理论,其在去除氮素和有机污染物的同时,能够实现同时硝化反硝化(SND),因此受到广泛关注.文章介绍了异养硝化-好氧反硝化菌的影响因素和一些已筛选菌的最佳脱氮效果,及其与传统硝化反硝化菌作用酶系的不同,列出了一些已筛选菌的氮代谢途径,并对中间产物NO2--N积累和复合菌方面的研究进展进行了综述,最后提出了异养硝化-好氧反硝化在生物强化应用中的研究现状和面临的挑战.
Research progress and challenges of heterotrophic nitrification-aerobic denitrification
In recent years,the discovery of heterotrophic nitrification-aerobic denitrification bacteria has broken the traditional theory.It is not only able to simultaneously remove nitrogen and organics,but also some bacteria can achieve simultaneous nitrification and denitrification (SND),so it has gained widespread attention.Our review focuses on the influence factors of heterotrophic nitrification-aerobic denitrification bacteria,the optimal nitrogen removal effect of some bacteria,the difference between traditional nitrification-denitrification bacteria and heterotrophic nitrification-aerobic denitrification bacteria and the nitrogen metabolic pathways of some bacteria.In addition,it shows the research progress in the aspects of NO2--N control and compound bacteria.Finally,the present situation of its application in bioaugmentation and challenges facing it are brought forward.
