厌氧氨氧化工艺在主流污水处理中的应用及其调控研究进展

Application of Anaerobic Ammonia Oxidation Process in Mainstream Wastewater Treatment and Its Regulation Research Progress

厌氧氨氧化工艺(Anammox)具有低能耗、低产泥量、高脱氮性能等特点,在处理垃圾渗滤液、污泥消化液等领域的应用与研究得到了广泛重视。尽管如此,受制于氨氮浓度低、有机物与水量波动大、低温等问题,影响了其在城市污水主流工艺的应用。本文在介绍厌氧氨氧化工艺的基础上,总结了以厌氧氨氧化为基础的组合工艺处理城市污水案例,分析了当前厌氧氨氧化工艺应用于城市污水处理的限制性因素以及新型调控手段与策略。进一步展望了厌氧氨氧化应用于城市污水主流工艺的发展方向,以期为厌氧氨氧化应用到主流污水提供理思路。

Anammox process has the characteristics of low energy consumption,low sludge production and high nitrogen removal performance.It has been widely applied and studied in the treatment of landfill leachate,sludge nitrifying liquid and other fields.However,its application in the urban sewage mainstream process is also subject to low ammonia nitrogen concentration,large fluctuation of organic matter and water volume,low temperature and other problems.Based on the introduction of the anaerobic ammonia oxidation process,this paper summarizes the case of a combined process based on anaerobic ammonia oxidation for urban sewage treatment and analyzes the restrictive factors of the application of the anaerobic ammonia oxidation process in urban sewage treatment,as well as new control methods and strategies.Finally,the development direction of the application of ANAMMOX to the mainstream process of urban sewage is prospected to provide a theoretical idea for the application of ANAMMOX in mainstream sewage.
