| dc.description.abstract | 本研究採用滲出液迴流系統，進行高溫(55℃)厭氧固態消化產甲烷實驗。實驗分成四組，以500g的成年新鮮豬糞，控制消化條件(如pH=6.8~7.2、封閉厭氧系統、溫度=55°C)依不同的迴流量(0 L/min； 0.36 L/min；0.9 L/min；1.8 L/min)進行甲烷濃度、甲烷日產量、甲烷總產量與VFA之討論。實驗結果得知，以迴流量為1.8 L/min豬糞之實驗，優於實驗組及其他對照組，其甲烷累積量達4.57 L、單日產甲烷最大量爲885 ml、比甲烷產量99.291 ml-CH4/g-VS及溶解性化學需氧量(SCOD)移除率爲59.39%。適量的迴流是有助於豬糞進行高溫厭氧固態消化反應，提高基質轉換率，從而提升甲烷產出。

| dc.description.abstract | This methane daily production, concentration total production and VFA experiment adopts the percolation system to circulate infiltrating fluid in the thermophilic (55℃) anaerobic solid-state digestion, weighting 500g fresh pig manure of total solids converses the different base ratio. As the experimental group as 0 L/min, while added 0.36 L/min；0.9 L/min and 1.8 L/min of flow rate in as three circulate infiltrating fluid comparison groups, respectively. The experimental results demonstrated that the group of 1.8 L/min in pig manure is superior to the control group and other comparison groups, such as the cumulative methane production of 4.57-liter, Day maximum methane production of 885ml, specific methane yield of 99.291 ml CH4 /g-VS and soluble chemical oxygen demand (SCOD) removal rate of 59.39%.The parameters demonstrate that adequate amount of circulate infiltrating fluid in pig manure to react the thermophilic anaerobic solid-state digestion, therefore, it can improve the substrate conversion rate and enhance the methane production.
