Chinese invention patent CN106434283A discloses a diatom culture plate type reactor, which sets a sandwich flow guide plate in the reactor box body, and is combined with LED and the like, thereby improving the space occupation of the algal liquid to the reaction box body. The sandwich flow guide plate is thin and has a large relative area, and the full contact of the algal liquid and the light source is realized through the step-by-step flow mode, which not only can reduce the mutual shading effect between cells caused by the large deposition of diatoms, but also can effectively remove the dissolved oxygen accumulation in photosynthesis, thereby providing a favorable growth environment for the high-density and high-quality culture of diatoms. However, in the culture process, it is difficult to directly grasp the culture condition of diatoms through the flow type culture mode.
