以燃煤发电为主的电力行业在保障我国能源供给的同时也是我国CO2的主要排放源之一。推进煤电固废综合利用对资源节约和减少碳排放具有显著的协同效应,是实现“双碳”目标的重要途径之一。重点介绍了煤电固废的综合利用现状,阐述了煤电固废在筑路、建材、生态修复、工程填筑等领域的综合利用途径及CO2减排方式;从促进CO2减排和增加CO2吸收两方面出发,分析了煤电固废在不同应用领域的降碳固碳效果,旨在为火电企业因地制宜选择固废利用与节能降碳技术路径提供参考。

The coal-fired power industry is one of the most major sources of CO emission while it is ensuring our country’ s energy supply. Promoting the comprehensive utilization of SW-CFP has a significant synergy on resource conservation and carbon emission reduction, and is one of the critical paths to achieve the goal of " double carbon" . This paper focuses on the present situation of the comprehensive utilization of SW-CFP, and elaborates the comprehensive utilization ways and CO emission reduction ways of SW- CFP in road construction, building materials, ecological restoration, engineering filling, etc. From the perspectives of promoting CO emission reduction and increasing CO absorption, the carbon reduction and sequestration effects of SW - CFP in different application fields were analyzed, which could provide reference proposal for thermal power enterprises to choose the technology path of solid waste utilization and energy-efficient carbon reduction to local conditions.
