Abstract：Taking a certain wastewater treatment plant in City H as the research object,a carbon emission model is constructed using the emission factor method,and the emissions are calculated based on the operation data from January 2022 to September 2024.The results show that the monthly average carbon emission of the plant is 1 361.97 tCO2,among which the indirect emissions due to electricity consumption are 529.80 tCO2 equivalent per month,and the indirect emissions due to the use of chemicals are 211.70 tCO2 equivalent per month.According to the calculation results,the indirect emissions related to electricity consumption and chemical consumption are the main source of carbon emissions for the wastewater treatment plant in City H.By strengthening operation management,adopting low-energy consumption equipment,and introducing intelligent dosing systems,energy consumption can be effectively reduced.At the same time,renewable energy technologies such as photovoltaic power generation can be supplemented to promote the green and low-carbon operation of the wastewater treatment plant.
