In recent years, the amount of CO2 emissions are causing global warming, CO2 immobilization technology can’t be ignored. In Taiwan, various CO2 reduction method, the use of algae fixed CO2 reduce the co2 pollution problems, and solid carbon frond resource, and therefore deemed to be one of the economic efficiency of the method. In this study, chlorella as the main object, discussion chlorella in a different growth factor, carbon sequestration efficiency and growth rate differences, by different inoculation concentration, temperature and light intensity, to identify the most suitable free environment for the growth and the best efficiency of carbon sequestration.
The experimental results show a linear relationship, the relationship between chlorophyll and algae dry weight, using the calibration curve can be calculated by the chlorophyll content of the algae dry weight calibration curve R2 = 0.998 accurately a very high degree. Also found that chlorella carbon fixation rate, not due to the different from inoculum concentration, another light intensity is too high or the temperature is too low will result in chlorella Yang system growth, ball algae growth and carbon fixation rate is quite obvious, chlorella growth in the range of an environment conducive to the growth and carbon fixation rate and growth rate will be greatly enhanced. A 30℃ environment to 4000 LUX continuous irradiation 24 hours and the initial water quality the best growth efficiency and carbon fixation rate was adjusted to pH = 6.0 can be achieved, in water 404.1 mg / L of carbon dioxide via the 5-day training will be depleted, and the chlorella cell concentration can be achieved 102.013 mg / L, the growth rate of 0.513 d-1.
