城市污水收集与处理系统碳排放监测评估技术研究进展

城市污水收集处理在保障公共卫生与健康等方面发挥着重要作用。近期有研究指出,城市排水系统和污水处理厂在运行过程中会直接或间接地产生温室气体排放。如何精准地监测评估城市排水系统与污水处理厂的碳排放水平,从而科学地提出污水治理碳减排路径与碳中和模式,是城市水污染控制协同实现"碳达峰、碳中和"目标的关键突破口,也是当前环境领域的科技前沿和重点。结合文献调研和前期研究基础,以城市排水系统和污水处理厂为主要对象,总结当前温室气体排放监测与量化评估的研究现状,并探讨影响碳排放监测评估技术发展的关键瓶颈问题,提出碳减排路径构建的科学思路,为研发新一代城市污水收集与处理系统碳排放监测评估技术提供建议路线。

RESEARCH ADVANCES IN CARBON EMISSION MONITORING AND ASSESSMENT OF URBAN DRAINAGE AND WASTEWATER TREATMENT SYSTEMS

Urban drainage and wastewater treatment facilities played a vital role in ensuring public health and sanitation over the past centuries.Recent research suggests that the implementation of integrated wastewater services can contribute to greenhouse gas emissions directly and/or indirectly.Consequently,it is very essential to accurately monitor and assess the carbon emissions during urban drainage and wastewater treatment systems operation and develop decarbonization pathways and carbon neutrality patterns for wastewater management.The deliverables of these investigations could create potential benefits in simultaneously achieving urban water pollution control and the"carbon dioxide emission peaking and carbon neutrality"goal.Such research is also related to the frontier and focus of science and technology in the environmental field.This review is intended to shed light on the current research trends and limitations related to carbon emission monitoring and assessment for urban drainage and wastewater treatment systems.Overall,this review provides useful information to help develop the next generation of carbon emission monitoring and assessment technologies for urban drainage and wastewater treatment systems.
