摘要
为探究厨余垃圾粉碎机(food waste disposer,FWD)应用后的潜在环境影响,分别从生活垃圾减量化效益,垃圾处理系统能量流变化,碳减排效益,酸化以及富营养化效应等方面系统地梳理针对该设备的当前研究进展。结果表明,FWD的应用可实现厨余垃圾的源头分离,直接减少了城市生活垃圾的收运数量,但系统的净能源产出仍存在不确定性;FWD在降低碳排放和酸化效应方面有正向作用,但会增加富营养化效应。未来研究重点建议聚焦于本地化的清单数据挖掘,深化厌氧消化模式和FWD模式的环境影响的对比研究,分析FWD普及率阈值与环境影响的相互关系,以及探究FWD应用的新模式。
Based on the literatures analysis,the relative studies on the potential environmental impacts of application of Food Waste Disposer(FWD)are reviewed.It summarized the literature study results in the context of municipal waste flow,energy consumption,carbon reduction and acidification,as well as eutrophication.Firstly,FWD installation can reduce the MSW flow in collection and transportation so as to divert the food waste from MSW to wastewater system.Secondly,there is uncertainty in the net energy output.Thirdly,FWD can reduce the carbon emission and acidification,but increase the eutrophication.The future research focus are suggested on these such four aspects as local data mining,comparison of environmental impact of FWD and anaerobic digestion,and relationship of FWD installation rate and environmental impacts,as well as developing new model of FWD application.
