摘　　要：焚烧处理是生活垃圾的主要处理方式,在焚烧过程中会排放一定的温室气体。以北京某生活垃圾焚烧厂为例,基于全流程对生活垃圾焚烧开展温室气体排放核算。结果表明:吨生活垃圾焚烧排放温室气体的CO_(2)当量强度约为0.55 t。吨生活垃圾焚烧的碳储存约为0.32 t,表明其具有较好的碳减排潜力。从生产环节来看,处理阶段和处置利用阶段排放的温室气体占排放总量的99.00%,其中在处理阶段CH4、N2O两类温室气体的贡献率为10.81%。经过计算,通过生活垃圾焚烧发电上网预计全国温室气体排放每年可以减少9.98421×107 t,减污降碳效果显著,对实现碳达峰碳中和目标意义重大。Incineration is the main treatment method for domestic waste,and a amount of greenhouse gases will be emitted during the incineration process.Taking a domestic waste incineration plant in Beijing as an example,greenhouse gas emission(GGE)accounting was carried out based on the entire process of domestic waste incineration.The results indicated that the CO_(2)equivalent intensity of GGE from domestic waste incineration was approximately 0.55 t/t.The domestic waste incineration had good potential for carbon reduction with 0.32 t/t of carbon storage capacity.From the perspective of production process,GGE from the treatment and utilization stages accounted for 99.00%of the total emissions.The contribution of CH4 and N2O was 10.81%in the processing stage.This study estimated that using domestic waste incineration to generate electricity was expected to reduce GGE by 99.8421 million tons per year nationwide,with significant pollution and carbon reduction effects.This is of great significance for achieving the goal of carbon peak and carbon neutrality.
