热解气化技术在我国村镇生活垃圾处理的应用现状

Application status of pyrolysis and gasification technology in rural domestic waste treatment

国家高度重视农村生态环境保护,多举措全面推进村镇生活垃圾治理,热解气化技术作为当前村镇垃圾处理模式的重要补充受到了广泛关注,并建立了大量的工程实例。文章介绍了热解气化技术的原理、相关标准规范和工程应用现状等,并对工程项目分布、数量情况进行了统计分析。通过检索调研,2010—2021年期间共实施1004个生活垃圾热解气化处理项目,主要集中在华南、西南和西北地区,87.1%的项目主要于“十三五”期间新增;同时,总结了已有热解气化工程项目特点及需要解决的问题,以期为我国村镇生活垃圾处理提供借鉴与参考。

Our country attaches great importance to the protection of the rural ecological environment,and takes various measures to comprehensively promote the treatment of the rural domestic waste.Pyrolysis and gasification technology as an important supplement of the current rural waste treatment mode had attracted extensive attention,and a large number of engineering examples had been established.This paper summarized the principle,relevant standards and specifications and engineering application status of pyrolysis and gasification technology,and made a statistical analysis of the distribution and quantity of engineering projects.Through searching and survey,a total of 1,004 domestic waste pyrolysis and gasification treatment projects were implemented during 2010—2021,mainly in south,southwest and northwest of China.87.1%of the projects were newly added during the"Thirteenth Five-Year Plan"period.At the same time,the characteristics of pyrolysis and gasification project and the problems that need to be solved were summarized,in order to provide a reference for the treatment of domestic waste in villages and towns in China.
