Abstract

Amid growing concerns over climate change, the need to reduce nitrous oxide (N₂O) emissions from sewage treatment is more urgent than ever. Sewage treatment plants are significant sources of N₂O due to its production as an intermediate in nitrification and its release into the air during aeration. Effective management of the nitrification process is therefore vital for controlling or eliminating these emissions. Despite substantial efforts to quantify and understand N₂O emissions from sewage treatment, success in reducing them has been limited. This review discusses and proposes promising solutions for reducing N₂O emissions in sewage treatment, evaluates the potential of various strategies, and identifies ways to accelerate their development and implementation.

污水处理中氧化亚氮零排放之路：硝化是可控的还是可避免的？

随着人们对气候变化的担忧日益加剧，减少污水处理过程中氧化亚氮（N2O）排放的需求比以往任何时候都更加迫切。污水处理厂是N2O的重要来源，因为它在硝化过程中作为一种中间体产生，并在曝气过程中释放到空气中。因此，有效管理硝化过程对于控制或消除这些排放至关重要。尽管在量化和了解污水处理产生的一氧化二氮排放方面做出了大量努力，但在减少一氧化二氮排放方面取得的成功仍然有限。本综述讨论并提出了减少污水处理中N2O排放的有希望的解决方案，评估了各种战略的潜力，并确定了加速其开发和实施的方法。
