摘要
厌氧氨氧化(Anammox)技术作为近年来新兴的自养脱氮工艺,具有无需外加碳源、低污泥产量、低能耗等优势。文中总结了厌氧氨氧化应用于主流污水处理工艺时面临的困难挑战,分析了厌氧氨氧化处理污水的最新研究进展,阐述了厌氧氨氧化菌(AnAOB)的截留、硝酸盐氧化菌(NOB)的抑制、有机物的不利影响等问题的具体解决方案。在节能减排的时代要求下,为实现能源回用、资源回收的废水处理模式,提出了可能实现能源自给的工艺组合,为实现主流厌氧氨氧化工艺工程化应用提供科学借鉴。
As an emerging autotrophic nitrogen removal process in recent years, Anammox technology has the advantages of no additional carbon source, low sludge output, and low energy consumption. Article summarizes the difficulties and challenges faced by Anammox when applies to mainstream wastewater treatment processes, and analyzes the latest research progress in the treatment of mainstream wastewater by Anammox. It elaborates the interception of Anammox bacteria(AnAOB), the inhibition of nitrite oxidizing bacteria(NOB), and the adverse effects of organic matter and other specific solutions. Under the requirements of era of energy saving and emission reduction, in order to realize energy reuse and resource recovery wastewater treatment mode, a process combination that may realize energy selfsufficiency is proposed, which provides a scientific reference for realizing the engineering application of mainstream Anammox process.
