doi:10.13304/j.nykjdb.2023.0626

Abstract

Abstract:

Kitchen waste can produce biogas through anaerobic digestion， achieving its reduction and recycling of renewable energy， and promote the development of the industry towards the “dual carbon” goal. The main hydrolytic acid-producing bacteria and various nutritive methanogens in the anaerobic digestion of food waste were summarized， and the influence of environmental factors on anaerobic digestion of kitchen waste in the process of bogging and the relationship between them and microbial activity were emphatically discussed. At the same time， based on the study on the whole life cycle of anaerobic digestion of kitchen waste， the impact of biogas production and application on the environment was analyzed. Finally， in view of the low efficiency of anaerobic digestion of kitchen waste， the prospect of system optimization was carried out to achieve the purpose of efficient recycling and high-value utilization of kitchen waste， so as to realize the transformation of energy structure and promote the green and low-carbon development of the city.

摘要：

厨余垃圾可通过厌氧消化生产沼气，实现其减量化和可再生能源的循环利用，促使行业发展向“双碳”目标靠近。总结了厨余垃圾厌氧消化过程中主要水解产酸菌和各营养型产甲烷菌，讨论了厨余垃圾在产沼过程中环境因子对厌氧消化的影响及其与微生物活性间的关系，同时基于厨余垃圾厌氧消化全生命周期研究，分析了沼气生产及其应用对环境的影响。最后，针对厨余垃圾厌氧消化产沼效能低下的问题，在系统优化方面进行了展望，以达到高效回收及高值化利用厨余垃圾的目的，进而实现能源结构转型，推动城市绿色低碳发展。
