- Abstract:
- From the perspective of carbon emission of urban and rural sewage treatment systems, this paper calculates the carbon emission intensity of typical urban and rural sewage treatment systems in a districted city in Central Jiangsu at important points before and after the action of improving quality and efficiency, and verifies the accessibility of carbon emission reduction target of urban sewage treatment system by combining with quantitative analysis and analog analysis of domestic research results. In 2019, 2025 and 2030, the total carbon emissions of the sewage treatment system are 42 894.1 t, 55 051.0 t and 63 553.9 t, respectively, and the carbon emission intensities of removing unit BOD are 2.62 kgCO2/kgBOD, 1.47 kgCO2/kgBOD and 0.55 kgCO2/kgBOD, respectively, indicating that the target of reducing carbon intensity by 18% by the end of the 14th Five-Year Plan are achievable. After checking the carbon peak time of the urban sewage treatment industry, it is found that the total carbon emissions of the districted city will decrease year by year from 2030 to 2033, and will decrease by 0.72%, 3.75% and 13.01% respectively from 2031 to 2033 compared with the previous year. The results indicate that the carbon peak target of urban sewage treatment industry can be reached in 2030, and the carbon reduction benefits are considerable.
