中国厨余垃圾处理技术及资源化方案选择

介绍了中国厨余垃圾的产量及特征，分析了厨余垃圾粉碎直排、填埋、焚烧、饲料、昆虫养殖、堆肥、转换能源和高值化利用处理技术的现状及优缺点，表明厨余垃圾资源化处理是未来的发展趋势，其中饲料化应是未来值得提倡的资源化技术之一.此外，对比了厌氧消化和好氧堆肥两大主流资源化模式的特点，厌氧消化和好氧堆肥分别适用于集中大规模处理和分散式、中小规模、源头减量处理的应用场景.最后，提出了适合中国厨余垃圾资源化的废弃油脂炼制生物柴油+厌氧消化产甲烷+沼渣好氧堆肥组合工艺方案，为厨余垃圾的高效资源化处理提供一定参考.

Food waste treatment technology and resource solution options in China

This paper introduced the production and characteristics of food waste in China, and the current status, advantages and disadvantages of food waste treatment technologies including crushing and direct discharge, landfill, incineration, feed, insect farming, composting, energy conversion and high value utilization were analyzed. It was shown that the resource treatment of food waste was the future development trend, among which the feed method should be one of the resource treatment technologies to be promoted in the future. Besides, the characteristics of the two mainstream resource recovery modes, anaerobic digestion and composting, were compared. Anaerobic digestion and composting were suitable for centralised large scale treatment and decentralised, small to medium scale, source reduction treatment scenarios respectively. Finally, a combined technology solution of biodiesel from waste oil + methane production from anaerobic digestion + composting of digestate was proposed, which was suitable for the recycling of food waste in China, and provided some reference for the efficient resource treatment of food waste.
