厨余垃圾厌氧消化对沼气微生物及环境的影响OA北大核心CSTPCD

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.
