摘　　要：厌氧氨氧化(anammox)是在厌氧条件下氨作为电子供体,亚硝酸盐作为电子受体,通过生物作用转化为氮气的过程。胞外多聚物是微生物分泌的、包裹在细胞外的复杂的高分子有机物,具有促进颗粒污泥形成等功能。文中问介绍了厌氧氨氧化系统胞外多聚物与其他常见微生物系统胞外多聚物不同的特点及应用。特点部分介绍了厌氧氨氧化系统胞外多聚物内的含氮化合物和阴离子聚合物及其吸附作用。目前常利用厌氧氨氧化系统胞外多聚物进行污水中有机氮的去除以及强化反硝化作用。Anaerobic ammonia oxidation(ANAMMOX) is a process in which ammonia acted as an electron donor and nitrite as an electron acceptor under anaerobic conditions, and is converted to nitrogen by biological action.Extracellular polymer is a kind of complex polymer organic matter secreted by microorganisms, which can promote the formation of granular sludge.The characteristics and applications of extracellular polymers in ANAMMOX system were introduced.The characteristics of ANAMMOX system in the extracellular polymer containing nitrogen compounds and anionic polymers and their adsorption were introduced.At present, the extracellular polymer of ANAMMOX system is often used to remove organic nitrogen and enhance denitrification in wastewater.
