LED光源種類對光合細菌在水中氨氮去除之影響 Chung-Sheng Yang 楊中勝 碩士 大葉大學 工業工程與科技管理學系碩士在職專班 101 The rapid development of optoelectronic technology since mid-1980 has significantly enhanced the brightness and efficiency of light-emitting diodes (LEDs). Light-emitting diodes (LEDs) provide a useful alternative for illuminating photobioreactors (PBR) because they have a long life expectancy and consume low energy. Additionally LED light is characterized by its narrow wavelength band, wherein LED lamps can be tailored for a specific wavelength band to match the photosynthetic absorption spectra of Photosynthetic bacteria (PSB). This study investigated the effects of five light sources on growth and NH4+-N removal of photosynthetic bacteria. Light sources were incandescent lamp (IL) and light-emitting diodes (LEDs) of white (LW), red (LR), blue (LB), and green (LG). Dark condition served as the control. For bacterial growth, light sources ranked greatest to least bacterial growth effect were LG > LW > IL > LR > LB > Dark. Additionally, The results showed that RL and BL can promote PSB on efficiency of NH4+-N remvoal,achieve approaching 100% in the aeration area.
