【Abstract】：This paper takes asludge treatment plantas an example toanalyze thecarbon emision reduction effects ofcoanaerobic digestion of municipal sludge and food waste.By comparing operational data from 2O17（sludge treatment alone）and 202o（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 production fromapproximately 4.126 million Nm³ to 12.775million Nm³，arise of 209.6% ，while carbon emission reduction grew from 8，809.14 tCO 2e to 22，771.97 tCO2e ，animprovement 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.

厌氧消化是在无氧条件下，通过微生物代谢活动，将污泥中的可降解有机物分解为 CH4 及副产物 CO2 、 H2 和 H2S[1] ，其中 CH4 可用于供能。（剩余5226字）
