摘要
在中国碳达峰、碳中和背景下,城市生活垃圾处理面临低碳减排的新挑战。文章提出在垃圾分类模式下,依托静脉产业园建设,通过各固废单元的协同处理,实现物质和能量双循环,减碳效益显著。结果表明:2020年全国城市生活垃圾的焚烧和填埋处理共减少518万吨CO_(2);同年,若湿垃圾在静脉产业园协同处理,比单独处理减少1500万吨CO_(2)。垃圾焚烧发电厂作为静脉产业园核心项目,采用炉排大型化、高参数设计、热电联产等技术全年可减少90万—500万吨CO_(2)。建议多源城市固废采用静脉产业园模式进行协同处置,实现减碳效益最大化。同时,响应国家“一带一路”倡议,推荐应用在东南亚等地区的发展中国家,为全球固废处理的碳减排贡献中国方案。
Under the context of China's carbon peak and carbon neutrality,the treatment of municipal solid waste(MSW)is facing new challenge to reduce carbon emission.This study suggests that significant carbon emission reduction and dual cycle of mass and energy can be realized,under the context of MSW classification,by the collaborative treatment of multi-source solid waste in Eco-Industrial Park.Results showed that in 2020,the incineration and landfilling of MSW in China reduced 5.18 million tons of CO_(2) emission,at the same year,15 million tons of CO_(2) emission could have been reduced if the wet waste was treated in Eco-Industrial Park rather than separate treatment.Waste-to-energy(WtE)plant is the core of the Eco-industrial Park,the adoption of larger grate,higher steam parameter,and thermoelectric cogeneration technologies in WtE plant contributes 0.95 million tons of CO_(2) reduction,annually.It was suggested that multi-source solid wastes should be treated in the Eco-industrial Park to maximize the benefits of carbon emission reduction.At the same time,in response to the national“one belt one road”initiative,the Eco-industrial Park was recommended to be applied in developing counties in Southeast Asia,contributing China's solutions to the carbon emission reduction of global solid waste treatment.
