餐厨垃圾的热转化和生物处理研究进展

Research progress on thermochemical transformation and biological treatment of food waste

随着城市发展和人们对美食的追求,餐厨垃圾的年产量逐年增长,其资源化利用受到人们越来越多的关注。餐厨垃圾产量大、组分复杂,具有“资源性”和“危害性”的双重属性。本文梳理了餐厨垃圾的产量特性,阐述了近年来餐厨垃圾的热化学处理技术和生物处理技术的研究现状及进展,分析了热化学处理过程中的反应参数和催化剂种类对餐厨垃圾热解性能和热解产物分布的影响,总结了生物处理过程中餐厨垃圾的优势,为今后餐厨垃圾的热化学转化和生物处理的研究提供方向。

With the urban development and people's pursuit of delicious food,the annual output of food waste is increasing year by year,and its resource utilization has attracted more and more attention.Food waste has large output and complex components,and has the dual attributes of"resource"and"harmfulness".This paper sorts out the yield characteristics of food waste,expounds the research status and progress of thermochemical treatment technology and biological treatment technology of food waste in recent years,analyzes the effects of reaction parameters and catalyst types in the thermochemical treatment process on the pyrolysis performance and pyrolysis product distribution of food waste,and summarizes the advantages of food waste in the biological treatment process.Based on this,it provides directions for the future research on thermal-chemical transformation and biological treatment of food waste.
