Abstract

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.
