Abstract: Ammonia nitrogen was one of the vital factor of atmospheric  pollution. Buried rubbish would generated liquid, which contains high COD and ammonia nitrogen. COD and ammonia nitrogen makes the way that removal ammonia nitrogen become invalid. Microbiological removal of ammonia nitrogen,which has advantage of grew fast, high-efficiency, removed rapidly, nod by-product, as well as convenient. Absolutely can replaced the physical-chemical methods. This paper summarized the methods of microbiological removal of ammonia nitrogen, including  nitrification-denitrifying, heterotrophic-nitrifier-aerobic-denitrifier, anaerobic-mmonia-oxidation(ANAMMOX), similtaneous-nitrification-denitrification(SND), short-cut nitrification denitrification and so on. The paper also prospected their future research direction, which was expected to provide theory support for the study on removal of ammonia nitrogen.

摘要： 氨氮是环境污染的主要因素之一。垃圾的填埋处理导致垃圾渗滤液的产生，渗滤液中的高氨氮和高有机物让众多物理去除氨氮的方法失效。微生物去除氨氮有着快速、高效、无副产物、方便等众多优点，可以完全代替物化法。概述了微生物法去除氨氮的最新研究进展，对硝化-反硝化法、厌氧氨氧化法、异养硝化好氧反硝化、短程硝化反硝化法、同时硝化和反硝化法等方法进行了综述，并展望了生物法去除氨氮今后的研究方向，以期为氨氮去除研究提供技术支持及借鉴。
