基于双碳和生活垃圾分类背景下的分类前后入炉生活垃圾焚烧产生的温室气体对比分析

Based on the Background of Double Carbon and Domestic Waste Classification,the Comparative Analysis of Greenhouse Gases Generated by Domestic Waste Incineration before and after Classification

通过对生活垃圾分类前后的入炉生活垃圾产生温室气体量的对比分析,发现生活垃圾分类分出的其他垃圾入炉焚烧产生的温室气体量比分类前焚烧的生活垃圾产生的温室气体量略小,但几乎相当。分类后生活垃圾中的碳含量明显增加,生活垃圾的热值增加,发电量也增加,同时,生活垃圾焚烧产生的温室气体量也增加。分类后发电量增加所相当于减排的温室气体量与碳含量增加所增加的温室气体产生量几乎相当,这也导致了生活垃圾分类前后入炉垃圾焚烧所产生的温室气体量变化不大的结果。

Through the comparative analysis of the greenhouse gas generated by domestic waste before and after the classification of domestic waste,it is found that the amount of greenhouse gas generated by incineration of other garbage separated from domestic waste classification is slightly smaller than that produced by domestic waste incinerated before classification,but it is almost the same.After classification,the carbon content in domestic waste increases significantly,the calorific value of domestic waste increases,the power generation also increases,and at the same time,the amount of greenhouse gases produced by domestic waste incineration also increases.The amount of greenhouse gases equivalent to the reduction of greenhouse gases equivalent to the increase in carbon content is almost the same as the amount of greenhouse gases produced by the increase in carbon content,which also leads to little change in the amount of greenhouse gases generated by incineration of domestic waste before and after classification.
