随着现代农业发展、新农村建设推进和农民生活水平逐步提高，农业和农村的能源消费也不断增长。沼气干发酵是指在无流动水的条件下进行沼气发酵的工艺，可以将传统的厌氧消化工艺中固态物含量由低于6～10%提高到20% 以上。干发酵提高了池容产气率和池容效率，降低了成本。干发酵技术具有节约用水、管理方便、产气率高、处理成本低等优点，已经成为厌氧发酵技术的研究热点。 With the development of modern agriculture, the advancement of new rural construction and the gradual improvement of farmers' living standards, energy consumption in agriculture and rural areas is also increasing. Biogas dry fermentation refers to the process of biogas fermentation under the condition of no flowing water, which can increase the solid content in the traditional anaerobic digestion process from less than 6-10% to more than 20%. Dry fermentation improves the tank capacity gas production rate and tank capacity efficiency, and reduces the cost. Dry fermentation technology has the advantages of water saving, convenient management, high gas production rate, and low treatment cost, and has become a research hotspot in anaerobic fermentation technology.
