探討溫度與種菌對豬糞與稻桿厭氧共消化產甲烷之影響
Effect of temperature and inoculum on methane production in anaerobic co-digestion of swine manure and rice straw
摘要
因為近幾年石油價格大幅攀升的原因,而讓生質能源又被重新被重視(如生質甲烷、生質氫氣、生質酒精、生質柴油等), 而且環保意識的高漲對農業廢棄物(如稻稈、花生殼、稻殼等)的回收再利用也日趨重視，所以是一個相當值得研究的課題。 本研究主要以豬糞和稻桿混和在厭氧的環境下消化產甲烷，主要以溫度 (40 ℃、55 ℃)和種菌 (改良式1號、改良式2號、改良式3號)為變因探討對產甲烷之影響，藉由上面兩個實驗找出厭氧發酵產甲烷的最佳操作條件，最後再利用最佳操作條件探討豬糞與稻桿三種揮發固含量(VS)比(3:1、1:1、1:3)的產氣效果。 實驗結果發現55 ℃的環境下添加改良式3號種菌的累積甲烷氣量可達到3328.49 54.51 mL，其產氣效果比其他操作條件好。在不同的揮發固含量比實驗中，以比例3:1的產氣效果最好，其產氣量可達3745.11 79.54 mL。

Because the sharp rise in oil prices in recent years, and let the biomass energy has been re-valued(biomethane、biohydrogen、bioethanol、biodiesel), and rising environmental awareness of agricultural waste recycling is also increasing emphasis. Therefore, it is a very worthy subject of study. In this study investigated the methane production by anaerobic co-digestion swine manure with rice straw. Mainly the parameter are temperature(40 ℃、55℃) and inoculum(improved number 1、improved number 2、improved number 3) to investigated the effect of methane production, and find the optimal operating condition to produce methane by anaerobic digestion with above two experiments. Finally,investigated the effect of swine manure(SW) with rice straw(RS) at three different SW to RS volatile solid ratio of 3:1, 1:1, 1:3 by optimal operating condition. The results indicate that, the cumulative methane production was 3328.49 54.51 mL under the condition of temperature at 55℃ and add inoculum of improved number 3, and the cumulative methane production was the best. Cumulative methane production was 3745.11 79.54 mL under volatile solid ratio at 3:1 was the best in the experiment of different volatile solid ratio.
