This project aims to unravel the dynamics of Nitrous oxide (N2O) production in wastewater treatment systems by combining continuous stable isotope tracing techniques with innovative experimental design and sophisticated mathematical modelling. Nitrous oxide (N2O) is a potent greenhouse gas and a major contributor to the carbon footprint of wastewater treatment systems. Yet we have a poor understanding of how it is produced in such systems. The outcomes of this project will benefit Australian water utilities by helping them to reduce N2O emissions.

该项目旨在通过将连续稳定同位素示踪技术与创新的实验设计和复杂的数学建模相结合，揭示废水处理系统中一氧化二氮（N2O）生产的动态。一氧化二氮（N2O）是一种强有力的温室气体，也是废水处理系统碳足迹的主要贡献者。然而，我们对它是如何在这样的系统中产生的了解甚少。该项目的成果将通过帮助澳大利亚水务公司减少N2O排放而使其受益。
