Abstract：
The proliferation of novel wastewater treatment processes has marked recent years, becoming particularly pertinent in light of the strive for carbon neutrality. One area of growing attention within this context is nitrous oxide (N2O) production and emission. This review provides a comprehensive overview of recent research progress on N2O emissions associated with novel wastewater treatment processes, including Anammox, Partial Nitrification, Partial Denitrification, Comammox, Denitrifying Phosphorus Removal, Sulfur-driven Autotrophic Denitrification and n-DAMO. The advantages and challenges of these processes are thoroughly examined, and various mitigation strategies are proposed. An interesting angle that delve into is the potential of endogenous denitrification to act as an N2O sink. Furthermore, the review discusses the potential applications and rationale for novel Anammox-based processes to reduce N2O emissions. The aim is to inform future technology research in this area. Overall, this review aims to shed light on these emerging technologies while encouraging further research and development.
摘要：
近年来，新型废水处理工艺的发展标志着，在碳中和的努力中变得特别相关。在这种情况下，越来越关注的一个领域是一氧化二氮（N2O）的生产和排放。本文综述了与新型废水处理工艺相关的N2O排放的最新研究进展，包括Anammox,部分硝化,部分反硝化,Comammox,反硝化除磷,硫驱动自养反硝化和n-DAMO.彻底检查了这些过程的优势和挑战，并提出了各种缓解策略。研究的一个有趣的角度是内源性反硝化作用作为N2O汇的潜力。此外，这篇综述讨论了基于Anammox的新型工艺减少N2O排放的潜在应用和基本原理。目的是为该领域的未来技术研究提供信息。总的来说,这项审查旨在阐明这些新兴技术，同时鼓励进一步的研究和开发。
