1. one kind is improved the closed photo bioreactor of the efficiency of light energy utilization that microalgae mass is cultivated, it is characterized in that:

  • be only at least provided with 2 pieces of baffle plates perpendicular to nutrient solution flow direction at the inner-wall surface of the plane of illumination of closed photo bioreactor, and the part or all of region of effective plane of illumination between the nutrient solution entrance that the region overlay bioreactor between baffle plate is set to outlet;

    Described closed photo bioreactor is the board-like bioreactor of horizontal positioned, circular pipe type bioreactor or ellipse tube type bioreactor;

    The length of the baffle plate in described board-like bioreactor is 30% ~ 100% of nutrient solution width of flow path in board-like bioreactor;

    The length of the baffle plate in described circular pipe type bioreactor or ellipse tube type bioreactor is 30% ~ 100% of the cross section arc length of nutrient solution runner plane of illumination.
