【摘要】 通过对城市生活垃圾厌氧消化进行批量实验,研究了温度对厌氧消化过程的影响,探讨了不同消化温度对产气量、发酵启动时间、不同固含量的消化程度的影响以及温度突变对厌氧反应器产气量的影响,同时对温度的影响机理进行了初步探讨。实验结果表明,城市生活垃圾厌氧处理的较佳温度为55℃,消化程度比较彻底,沼气中的甲烷含量较高。更多还原

【Abstract】 The influence of different temperature on performance of anaerobic fermentation was studied. The parameters adopted for evaluation were biogas production、fermentation starting time and the proportions between solid/water during the digestion process under different temperature. The evaluation of sudden change of temperature affecting the fermentation process were studied too. The result indicated that the optimum temperature for MSW anaerobic fermentation was 55℃. The organic solid waste were degraded very well and the methane concentration in biogas were comparatively high during 55℃.更多还原
