BIOREACTOR WITH BUILT-IN LIGHT SOURCE AND MICROALGAE CULTURE METHOD

摘要

A bioreactor with a built-in light source comprises a reaction vessel, a material feeding and discharging device, a light-emitting device, a nutrient distributing device and a gas distributor, wherein the reaction vessel is provided thereon with a cover plate and serves to accommodate a culture liquid for microalgae growth; the material feeding and discharging device is in sealing connection with the reaction vessel and provided thereon with a valve and a switch, and microalgae are pumped into or out of the reaction vessel through the material feeding and discharging device; the light-emitting device is used for generating a light source required for microalgae growth; the nutrient distributing device is used for supplying nutrients required for microalgae growth into the reaction vessel; and the gas distributor is used for supplying gases required for microalgae growth into the reaction vessel. The bioreactor with the built-in light source is not affected by weather changes, can realize stage-by-stage microalgae reproduction, has high controllability, and is beneficial to realization of stable and continuous industrialized production; and due to the serial and/or parallel connection system of the bioreactor, large-scale microalgae culture becomes more efficient.
