Nitrous oxide (N2O) is a potent greenhouse gas that can be produced during biological nitrogen removal in wastewater treatment systems. N2O emissions primarily occur in aerated zones due to active striping, and ammonia-oxidizing bacteria (AOB) are the major contributors to N2O production under such conditions. The project aims to carry out a systematic study on N2O production by AOB in mixed culture wastewater treatment systems. The project aims to advance the fundamental knowledge on N2O production pathways by AOB under different operational conditions, and deliver a modelling tool for reliably estimating N2O emission from wastewater treatment systems as well as strategies to reduce the emissions.

一氧化二氮（N2O）是一种潜在的温室气体，可在废水处理系统的生物脱氮过程中产生。N2O排放主要发生在曝气区，由于活跃的剥离，和氨氧化细菌（AOB）是在这种条件下的N2O生产的主要贡献者。本项目旨在对混合养殖废水处理系统中氨氧化细菌产生N2O的过程进行系统研究。该项目旨在提高对AOB在不同运行条件下N2O产生途径的基础知识，并提供一个可靠估计废水处理系统N2O排放的建模工具以及减少排放的策略。
