| 摘 要： | 温室气体产生是"碳中和"背景下污水处理行业亟待解决的问题之一,准确掌握我国主要城市区域污水处理厂温室气体的产生特征和变化规律是制定减排政策的前提。基于污水处理量的排放因子法,建立了2015-2019年中国五大城市群城镇污水处理厂温室气体二氧化碳(CO2)、甲烷(CH4)和氧化亚氮(N2O)的排放清单,分析了温室气体排放的时空分布和影响因素。结果表明:五大城市群城镇污水处理厂温室气体排放量逐年升高,长江三角洲城市群排放量始终最高,2019年达到2042.78 Gg CO2-eq,汾渭平原城市群排放量最低;珠江三角洲城市群人均温室气体排放量最高,2019年达到20.36 kg/人;相关性分析显示,污水厂温室气体排放量与人口、GDP、污水处理能力和污水处理率呈显著正相关。

| Abstract: | The issue of greenhouse gases (GHGs) production is one of the problems to be solved for the wastewater treatment industry under the background of "carbon neutrality" .An accurate grasp of the production characteristics and variations of China's major urban areas is the prerequisite of formulation reduction policies on GHGs emissions.The emission factor method based on the treated sewage amount was used to establish the emission inventory of GHGs of carbon dioxide (CO2),methane (CH4),and nitrous oxide (N2O) from municipal wastewater treatment plants (MWWTPs) of five major urban groups in China during 2015-2019 in this article,and the temporal and spatial distribution and influencing factors of GHGs were analyzed.The results showed that the GHGs emission amount from MWWTPs of the five major urban groups increased during the five years.The highest emission amount was observed in the Yangtze River Delta urban group with the value of 2042.78 Gg CO2-eq in 2019,and the lowest was observed in Fenwei Plain urban group.The Pearl River Delta urban agglomeration had the highest per capita GHGs emission amounts,with a value of 20.36 kg/person in 2019.Correlation analysis showed that GHGs emission from MWWTPs were significantly positively correlated with the factors of population,GDP,wastewater treatment capacity,and wastewater treatment rate. |
