碩士 / 國立屏東科技大學 / 生物機電工程系所 / 98 / Taiwan is in the subtropical area surrounded by the sea, having a wealth of marine resources and a wide variety of agricultural products. The rich biological diversity is not only helpful in the development of biomass energy and other related sources of raw materials in Taiwan, but also solves the problem of uncontrollable energy (including biomass) that mostly imports from overseas. Thus, how to effectively expand and utilize the currently available resources is an imminent issue.
This study mainly used sargassum cristaefolium and the after-harvest banana waste (banana pedicels) to study the feasibility of anaerobic fermentation, and thus to investigate the degradation rate of fermentation after adding fiber hydrolysis enzymes. At the first stage, the influences of the the characteristics of raw materials composed of C/N ratio on the whole anaerobic fermentation system were experimented. In batch experiments, when the organic load was 4gVS, mixed 1:10 sargassum cristaefolium and banana pedicels, the gas production was 1101.5±0.2ml/h and the concentration 80%, which was significantly higher than the other mixture proportions. The second stage was to add various amounts of fiber hydrolysis enzymes A-300 (300ml), A-200 (200ml), A-100 (100ml) and compared with the non-added group (the control group); the total gas outputs in A-300, A-200 were 1982±0.2ml/h and 1934±0.2ml/h respectively, which were also significantly higher than the non-added group of 655±0.2ml/h; for the suspended solids in A-300 and A-200, the fiber degradation rates were better than the other groups. Thus, adjusting C/N ratios and adding different amounts of enzymes helped to improve the fermentation efficiency.
