Abstract: Disclosed is a mass-cultivation system for microalgae, including a reactor that contains a cultivation liquid in the interior thereof, wherein the liquid includes functional particles. According to the mass-cultivation system for microalgae according to the present invention, because various functions that are necessary for cultivation of microalgae may be uniformly distributed in a cultivation liquid by allowing functional particles having various functions to flow in the cultivation liquid, a suitable environment may be created based on the cultivation of a large amount of microalgae and the growth of microalgae so that a high efficiency cultivation system may be realized while the problems of mass-cultivation of an existing cultivation system may be solved.
