Diverse nitrogen-transforming microorganisms with a wide variety of physiological properties are employed for biological nitrogen removal from wastewater. There are many technologies that achieve the required nitrogen discharge standards; however, greenhouse gas emissions and energy consumption constitute the bulk of the environmental footprint of wastewater treatment plants. In this review, we highlight current and proposed approaches aiming to achieve more energy-efficient and environment-friendly biological nitrogen removal, discuss whether new discoveries in microbial physiology of nitrogen-transforming microorganisms could be used to reduce greenhouse gas emissions, and summarize recent advances in ammonium recovery from wastewater.
从废水中进行生物脱氮时会用到具有各种生理特性的多种氮转化微生物。有许多技术可以达到所需的氮排放标准；但是，温室气体排放和能源消耗构成了污水处理厂环境足迹的大部分。在这篇综述中，我们重点介绍了旨在实现更节能和更环保的生物脱氮的现有和拟议方法，讨论了氮转化微生物的微生物生理学新发现是否可用于减少温室气体排放，并总结了从废水中回收氨的最新进展。
