碩士 / 國立臺北科技大學 / 環境工程與管理研究所 / 103 / In 21st century, energy saving, carbon reduction and food are the most popular topics for sustainable development. Algae can grow quickly, absorb carbon dioxide and produce lots of biomass, and biomass of algae can be used in food, medical biotechnology and biodiesel to help sustainable human development. In this study, a newly-designed vertical column photo-bioreactor is combined with remote monitoring for algae cultivation and possibility for scaling up. The study is divided into two parts, cultures of algae in the laboratory and photo-bioreactor pilot-scale plant. In first part, we explore the growth of algae parameters, and in the second part, photo bioreactor scaling up problem was discussed.
The results show that the culture medium diluting 10 times is not only better when culturing Spirulina maxima but reducing the cost of cultivation. The optical path length of 13.2cm resulted in the optimum areal biomass productivity and the reactor of diameter of 15cm was suggested. The photo-bioreactor test result show that the system can keep functional by providing pressure, but hydraulic and pneumatic power source should be separated to avoid affecting the stability of the gas pressure. Although Spirulina maxima of growth rate is good in the laboratory, the growth rate of Spirulina maxima when algae culturing in photo-bioreactor is only half of that in the laboratory due to limitation of pilot-scale plant environment. The pilot-scale plant is suitable for culturing species and mass production, which can follow the growth rate of algae to adjust cycle, semi-circle or full cycle. This study also builds up the monitoring platform to demonstrate the feasibility of remote monitoring system for the photo-bioreactor.
