市政污泥与餐厨垃圾协同厌氧消化的碳减排量计算OA

This paper takes a sludge treatment plant as an example to analyze the carbon emission reduction effects of co-anaerobic digestion of municipal sludge and food waste.By comparing operational data from 2017(sludge treatment alone)and 2020(co-treatment of sludge and kitchen waste),the impact of co-digestion on biogas production and emission reduction was investigated.The results show that co-digestion increased biogas pro-duction from approximately 4.126 million Nm³to 12.775 million Nm³,a rise of 209.6%,while carbon emis-sion reduction grew from 8,809.14 tCO2e to 22,771.97 tCO2e,an improvement of 158.5%.To further reduce carbon emissions,the plant could adopt measures such as replacing part of its net purchased electricity and optimizing nitrogen removal processes.
