餐厨垃圾预处理技术综述

摘要

介绍了餐厨垃圾的理化特性，并探讨了目前可用于餐厨垃圾的预处理技术，包括预分选（破袋、人工分选、滚筒筛分、弹跳分选、风力分选、红外分选、破碎）及生化预处理（湿热处理、干热处理、生物干化、生物淋滤）技术的特点和作用。%The physical and chemical properties of food waste were introduced. And the characteristics and functions of present food waste pretreatment technologies were discussed, including presorting (such as bag-breaking, manual sorting, drum screening, bounce separation, pneumatic separation, infrared separation, and crushing) and biochemical pretreatment (such as heat-moisture treatment, dry-heating treatment, bio-drying, and bio-leaching).
