摘要
介绍了厨余垃圾的来源与特征,讨论了厨余垃圾的资源化技术:主要包括堆肥、厌氧发酵、真空油炸、蚯蚓生物处理、乳酸发酵以及生物制氢等,其中家庭垃圾处理机和小容量垃圾系列处理机堆肥技术具有费用低和实现源头减量化等优点。生物制氢、厌氧发酵和燃料电池发电系统的开发研究,为废物变清洁能源开辟了新的途径。此外,利用厨余垃圾制取乳酸,进而合成生物降解性塑料(聚乳酸)的技术,可为治理困扰人类的"白色污染"作出贡献。
The source and the characteristics of food wastes are introduced.The recycling technologies for the wastes,such as composting,anaerobic digestion,deep-fry in vacuum,biotechnology with earthworm,fermentative production of lactic acid as well as biological hydrogen production are discussed.The use of family processors of small volume for the decomposition of food wastes,which cost less and can decrease wastes from the source,is an ideal technology.Biological hydrogen production and the technique of the anaerobic digestion combined with the fuel cell generating system provide a new way for the transition from wastes to energy.Furthermore,the utilization of biodegradable plastics (poly-lactic acid) synthesized by lactic acid produced from food wastes can help to get rid of the problem of the 'white pollution'.
