Reducing direct greenhouse gas emissions from urban wastewater systems

该项目旨在为水务公司制定一个系统框架，以监测和减少废水系统的直接温室气体排放。将制定标准化监测方案，开展前所未有的全国抽样活动。获得的数据，连同微生物特征和机制分析，将用于开发新的模型，以准确预测温室气体排放。预期成果包括精确监测排放的协议、预测各种条件下排放的模型以及针对典型电厂配置的减缓指南。预期的效益是显著减少城市水工业的温室气体排放，并支持其到2050年实现净零排放目标。

This project aims to develop a systematic framework for water utilities to monitor and reduce direct greenhouse gas (GHG) emissions from wastewater systems. A standardised monitoring protocol will be developed to conduct an unprecedented nationwide sampling campaign. The obtained data, with microbial characterisation and mechanism analysis, will be used to develop novel models for accurate prediction of GHG emissions. Expected outcomes include protocol to accurately monitor emissions, models to predict emission under various conditions, and mitigation guideline for typical plant configurations. The anticipated benefit is a significant reduction in GHG emissions from urban water industry and support it to meet net-zero-emission goal by 2050.
