生物废水处理中的一氧化二氮排放缓解

在紧迫的环境问题中，废水处理过程中排放的一氧化二氮 (N 2 O) 已成为学术和实践研究的焦点。除了影响 N 2 O 排放的关键过程因素外，本综述还提供了关于 N 2 O 生产和消耗的生物途径的最新观点。然后通过讨论概述了当前的研究趋势，包括应变和反应器方面。最后但同样重要的是，提出了研究需求。需要进行整体生命周期评估，以评估提议的缓解策略或恢复方案的技术和经济可行性。这篇综述还为提出的关于 N 的未来研究前景提供了背景信息。2 O 减缓和恢复技术。正如所指出的，产生的 N 2 O 气体产品的稀释效应会阻碍其用作可再生能源；相反，它作为一种有效的氧化剂被提议作为一种有前途的回收选择。

Nitrous oxide (N2O) emitted from wastewater treatment processes has emerged as a focal point for academic and practical research amidst pressing environmental issues. This review presents an updated view on the biological pathways for N2O production and consumption in addition to the critical process factors affecting N2O emission. The current research trends including the strain and reactor aspects were then outlined with discussions. Last but not least, the research needs were proposed. The holistic life cycle assessment needs to be performed to evaluate the technical and economic feasibility of the proposed mitigation strategies or recovery options. This review also provides the background information for the proposed future research prospects on N2O mitigation and recovery technologies. As pointed out, dilution effects of the produced N2O gas product would hinder its use as renewable energy; instead, its use as an effective oxidizing agent is proposed as a promising recovery option.
