Abstract

In this study, we report the long term operation results of analyses of characteristics of the Rakuno Gakuen University Biogas generation plant (BGP), which has been in operation since March 2000. We evaluated using data for the 11-year period between April 2000 (FY2000), when BGP was built, and March 2011 (FY2010). The average biogas production per unit showed substantial fluctuations during this period, increasing from 20 m³ during the trial operation period in FY2000 to 30–40 m³ in FY2001–FY2006, and then decreasing to 15–25 m³ in FY2007–FY2010. The optimal methane fermentation facility temperature for steady methane gas production was approximately 40 °C. In FY2007, this BGP experienced its first localized functionality decline in energy use, including methane fermentation and power generation facilities. This resulted from changes in the substrate characteristics, inputs, and methane fermentation facility temperature, indicating that operations need to accommodate such changes in the long term.

畜禽粪便管理沼气厂长期运行结果的绩效评价

在本研究中，我们报告了自2000年3月开始运行的乐野学园大学沼气发电厂(BGP)的特征分析的长期运行结果。我们使用从2000年4月(2000财年)BGP建立到2011年3月(2010财年)的11年期间的数据进行评估。在此期间，单位平均沼气产量波动较大，从2000财年试运行期间的20 m3增加到2001 - 2006财年的30-40 m3，然后下降到2007 - 2010财年的15-25 m3。稳定产甲烷的最佳甲烷发酵设施温度约为40 °C。在2007财年，该BGP经历了第一次能源使用的本地化功能下降，包括甲烷发酵和发电设施。这是由于底物特性、投入和甲烷发酵设施温度的变化造成的，表明操作需要长期适应这种变化。
