However, the dissolving efficiency of carbon dioxide in the culture solution is low, and the carbon dioxide is absorbed and utilized by the microalgae with the efficiency of less than 5%, so that the CO is dissolved in the algae solution2The concentration is low, most of carbon dioxide escapes to the air, so that the waste of carbon dioxide resources is caused, and the culture cost of microalgae is increased. Meanwhile, a large amount of carbon dioxide enters the atmosphere, and the purpose of reducing the carbon dioxide emission by using microalgae is deviated.
