摘　　要：温度是影响微生物活动的关键因素,厌氧发酵通常采用中温或高温发酵,一般认为中温和高温之间存在“低速发酵”过渡区。文章通过试验研究及工程验证发现,餐厨垃圾浆料、牛粪、酒糟和黄贮玉米秸秆在过渡区的产气速率和产气量均明显优于中温或高温发酵,分析原因为中温和高温过渡区存在中温和高温甲烷菌群的叠加优势。Temperature is the key factor affecting microbial activity.Anaerobic fermentation at mesophilic and thermophilic temperatures have been widely adopted,and the intermediate zone between mesophilic and thermophilic temperatures is generally considered as"Low speed anaerobic fermentation area".Through experiments and engineering verification,it was found that the gas production rate and total gas output of kitchen waste slurry,cow dung,vinasse,and corn straw silages in the transition zone were obviously better than that of mesophilic or thermophilic temperature fermentation.It may be due to the co-existence of mesophilic and thermophilic methanogens which caused an overlap of methanogens in the intermediate zone.
