以产物为导向的厨余垃圾厌氧发酵方式分析与建议

ANALYSIS AND SUGGESTION OF PRODUCT-ORIENTED ANAEROBIC FERMENTATION OF KITCHEN WASTE

随着我国垃圾分类政策的推行和"双碳"目标的引领,厨余垃圾处理行业正处于快速发展阶段。厨余垃圾厌氧发酵相较于填埋和焚烧等传统工艺,具有资源利用率高、环境友好等优点,且厌氧发酵产物的多样性使其具有广泛的发展和应用潜力。总结了厨余垃圾厌氧发酵机理与发展现状,重点分析了以产沼和产酸为主要产物的研究与工程应用情况,并对厨余垃圾厌氧发酵领域目前存在的问题与未来的发展方向进行了探讨,以期为不同地区筛选适宜的厨余垃圾厌氧发酵处理方式提供支撑,促进厨余垃圾资源化利用技术的高效与低成本发展,加强厨余垃圾的有效消纳和资源化产物的多场景应用。

With the implementation of China’s garbage classification policy and of the Dual Carbon Goal,the kitchen waste treatment industry is in a rapid development stage.Compared with traditional processes such as landfill and incineration,anaerobic fermentation of kitchen waste has the advantages of high resource utilization and environmental friendliness;the diversity of anaerobic fermentation products gives it a wide range of development and application potential.This article summarizes the mechanism and development status of anaerobic fermentation of kitchen waste,and focuses on analyzing the research and engineering application of producing biogas and acid as the main products.At the same time,the current problems and future development directions in the field of anaerobic fermentation of kitchen waste are discussed.The aim is to provide support for the selection of suitable anaerobic fermentation treatment methods for kitchen waste in different regions,promote the efficient and low-cost development of kitchen waste recycling technology,and strengthen the effective disposal of kitchen waste and the multi-scenario application of resource products.
