摘　　要：研究了不同处理量下,系统反应温度对餐厨垃圾厌氧消化过程中产气量的影响,分析了餐厨垃圾厌氧消化处理过程中,产气量与进料TS浓度的关系以及气体成分的差异。结果表明:在相同处理量下,与中温35℃的反应温度相比,高温55℃下系统产气速率较快,产气高峰较早到达;系统日产气量与进料TS的变化基本一致,平均产气能力达到0.45 m3/kg,气体成分中甲烷含量均高于55%。In the process of food waste anaerobic digestion,the effects of temperature on biogas production under different treating capacities were studied.The relation between biogas production and total solid concentration of food waste were analyzed,as well as the components of the biogas.The results showed that under the same treating capacity,thermophilic anaerobic digestion（55 ℃） had a higher biogas production rate and the highest production day came earlier compared with mesophilic anaerobic digestion（35 ℃）.Moreover,the variation of the daily biogas production was nearly the same as the variation of total solid.The average biogas production rate was 0.45 m3/kg and the percentage of methane was more than 55 percent.
