城市生活垃圾循环利用系统物质代谢框架的构建

Metabolism framework on recycling system construction of municipal solid waste

讨论了传统的物质流分析(MFA)方法用于城市生活垃圾代谢分析的适用性及不足之处,在此基础上结合城市生活垃圾的处理流程,对传统的MFA框架进行了改进,构建了适合城市生活垃圾代谢分析的框架,并对新框架的3个模块进行了详细的说明,建立了相应的评价指标体系并给出了应用实例。城市生活垃圾循环利用系统物质代谢分析框架能够清楚地描述生活垃圾进入经济系统后的具体流向和流量,为描述城市生活垃圾的代谢情况提供了定性及定量化的分析工具。

The paper discussed the shortages of traditional Material Flow Analysis when it is used to analyze the Municipal Solid Waste （MSW） metabolism. Combined with the MSW disposal process, the frame and indexes of the traditional MFA were improved, and a new framework was built which was suitable for the MSW metabolism analysis. The three parts of the new framework were described in detail, and the new index system was also given. Lastly, an application example was given. The MSW metabolism framework can show the flow directions and flow quantities of MSW clearly in the economic system, and provide qualitative and quantitative analysis tools for describing the metabolism of MSW.
