Abstract
A solar powered spectral photosynthetic bioreactor system for culturing microalgae at high density, the system comprising a photobioreactor and further comprising a solar collector, optical fiber, an illuminant device within the photobioreactor, and a residual gas absorption device and culture medium separation and recovery device each connected to the photobioreactor; the illuminant device having one end connected to a spectral light intensity adjusting device installed above the photobioreactor; the adjusting device connected to the solar collector via the optical fiber; a gas distributor provided between the underside of the illuminant device and a base part of the photobioreactor; the distributor connected to an output end of a gas mixing device. This system can effectively improve utilization of solar energy, lower external electrical power consumption, and resolve the problems of solar energy being intermittent and unstable in nature and difficult to collect, ensuring continuous and stable culturing of microalgae.
