摘　　要：针对我国目前进行的餐厨废弃物资源化与无害化试点城市建设,以广泛采用的厌氧消化技术为研究对象,进行物质流分析,评价了其资源化利用情况。得出:我国餐厨废弃物厌氧处理技术资源化产品仅为输出物质的23.7%,废渣和废水占输出的76.3%;餐厨废弃物无害化处理率平均为73.5%,资源化利用率平均为24.4%。最后,针对餐厨废弃物厌氧消化废水废渣产量大、资源化利用率低等问题,提出将沼液沼渣合理利用,将垃圾分类就地处理以及改进厌氧消化技术等措施。Aiming at the food waste recycling and reutilizing pilot cities in China, taking anaerobic digestion technology as research object, the material flow of anaerobic treatment was analyzed and the recycling condition was assessed. The conclusion was drawn that recycling products composed only 23.7% of the output materials, and that waste residue and wastewater composed 76. 3%. The disposal rate of food waste was 73.5% on average, while the resource efficiency was 24. 4% on average. Finally, to solve the problems including the massive digestate and low resource efficiency, it was suggested that the digestate should be reused, food waste be sorted and disposed on the spot, and anaerobic digestion technology be improved.
