Research on Carbon Emission Accounting of Typical Sewage Treatment Plant in Zhongshan City
Sewage treatment plants are one of the main sources of carbon emissions in the field of environmental protection,therefore,in order to help achieve China's"dual carbon target",it is necessary to carry out carbon emissions accounting and quantification of sewage treatment plants,find out the resource energy consumption and carbon emission bottom number of sewage treatment process,scientific assessment of carbon emissions of sewage treatment plants,and dig the potential of energy saving and carbon reduction of sewage treatment plants.In this study,a typical sewage treatment plant in Zhongshan City was selected as the research object.Based on the annual operation data of the sewage treatment plant,a scientific accounting method was adopted to conduct comprehensive carbon emission accounting for the sewage treatment plant from the perspective of direct discharge and indirect discharge.The results show that the total direct greenhouse gas emissions from the wastewater treatment process of the Zhongjia sewage Treatment Plant in 2022 are 6145.73 tCO2-eq,and the indirect greenhouse gas emissions generated by electricity consumption in the whole year are 15,081.65 tCO2-eq.Indirect greenhouse gas emissions from the use of related agents totaled 2164.52 tCO2-eq.It can be seen from the results that for the greenhouse gas directly discharged from the Zhongjia sewage treatment plant,reducing its emissions will cause the instability of the sewage treatment effect and the emission reduction space is small.For indirect emissions,Zhongjia sewage treatment plant has the highest indirect emissions due to power consumption,accounting for 68%,and has great carbon reduction potential.In the later stage,energy consumption can be reduced by strengthening operation management,intelligent operation,and the use of low-energy equipment and other ways to reduce indirect greenhouse gas emissions.
