Abstract
According to the accounting method of the newly released group standard Guidelines for Accounting Greenhouse Gas Emissions from Urban Sewage Treatment Plants in Shanghai(T/SWARTA 001-2023)in 2023,42 municipal wastewater treatment plants(WWTPs)in Shanghai were selected as the research objects.Based on the production activity data of each WWTP in 2022,the greenhouse gas emissions and emission intensities within the scope of accounting were categorized and summarized to compile statistics and the factors influencing the greenhouse gas emission intensities of municipal WWTP in terms of the treatment area,the main processes of wastewater treatment,as well as the sludge treatment process and facilities were subjected to descriptive and ANOVA analyses.The results showed that the total annual greenhouse gas emissions from urban WWTP in Shanghai during the production activities,calculated according to the group standard,was about 2.3 × 106 t CO2 eq,and the greenhouse gas emission intensity generated by the citywide municipal WWTPs that treated 1 m3 wastewater was 0.76 kg CO2 eq,with the contribution of carbon emissions from urban sludge treatment facilities being 22.16％.Through one-way ANOVA,it is concluded that the distribution area of wastewater treatment facilities and process type do not have a significant effect on the intensities of sewage treatment greenhouse gas emissions(P＞0.05);while the distribution area of sludge treatment facilities and process type have a significant effect on the intensities of sludge treatment greenhouse gas emissions(P＜0.05).关键词
