    • A system for purifying a polluted air by using algae such as Spirulina is capable of reducing carbon dioxide (CO.sub.2), nitrogen oxide (NO.sub.x) and/or sulfur oxide (SO.sub.x) in the polluted air and generating oxygen. That is, this system comprises a culture tank filled with a culture fluid including the algae, an air supply unit for forcing the polluted air into the culture fluid to dissolve carbon dioxide and nitrogen oxide and/or sulfur oxide in the culture fluid, and a lighting unit for radiating a light to the culture fluid. By radiating the light to the culture fluid in the presence of carbon dioxide, photosynthesis of the algae is promoted to convert carbon dioxide into oxygen. In addition, the algae use the nitrogen oxide and/or sulfur oxide as a nutrient during the photosynthesis. As a result, the present system can efficiently purify the polluted air to generate a purified air, which is rich in oxygen.
    • 通过使用诸如螺旋藻之类的藻类来净化污染空气的系统能够减少污染空气中的二氧化碳(CO 2),氮氧化物(NO x)和/或硫氧化物(SO x)并产生氧气。 也就是说,该系统包括填充有包括藻类的培养液的培养槽,用于将污染空气强迫到培养液中以将培养液中的二氧化碳和氮氧化物和/或硫氧化物溶解的空气供给单元,以及 用于向培养液照射光的照明单元。 通过在存在二氧化碳的情况下将光照射到培养液中,促进藻类的光合作用以将二氧化碳转化为氧气。 此外,藻类在光合作用期间使用氮氧化物和/或硫氧化物作为营养物。 结果,本系统可以有效地净化污染空气,产生富氧的净化空气。
