中文摘要：

我国城市生活垃圾产生量巨大且以填埋方式为主，不仅占用了大量的土地，还对环境造成了潜在的危害。城市生活垃圾中有机物含量较高，采用厌氧消化技术能有效实现垃圾处理的资源化，然而温度是影响厌氧生物处理工艺的重要工艺参数。本文在废水厌氧消化及农村沼气发酵的理论和实践基础上，选择总固体含量（TS）质量分数为17．5％，对东华理工大学生活垃圾进行厌氧消化实验，研究了不同温度对产气量、消化时间的影响以及温度突变时厌氧消化过程的影响。实验表明，温度为55℃时，该生活垃圾厌氧消化效果好，时间短，产气量高，是一个理想的温度。

英文摘要：

The huge amount of municipal solid waste and its landfill-based disposal not only take up a lot of land, but also generate potential harm to the environment. Because of the high organic content of municipal solid waste, anaerobic digestion technology can effectively achieve the resourcefulness of the waste disposal resource. Howev- er, the temperature is an important processing parameters which can affect anaerobic biological treatment. Based on the theory and practice of wastewater anaerobic digestion and rural biogas fermentation, the batch experiments is performed under the digestion （TS = 17.5% wt） to study the influence of different temperatures and fermenta- tion starting time on performance of anaerobic bioprocess. The evaluation of sudden change of temperature affect- ing the fermentation process is studied. The results indicate that the optimum temperature for MSW anaerobic fer- mentation was 55 ℃, and it is the best temperature. The organic solid waste are degraded very well and the meth- ane concentration in biogas are comparatively high under the temperature of 55 ℃.
