Microalgae half-dry solid state adherent cultivation device for alternate illumination of bright and dark light

Abstract

The invention belongs to the field of microalgae cultivation, and particularly relates to a microalgae half-dry solid state adherent cultivation device for alternate illumination of bright and dark light. The microalgae half-dry solid state adherent cultivation device comprises a bracket system, an adherent cultivation unit, a speed regulating motor, a liquid supplement pipe, a liquid collection tank and a peripheral protection cover, wherein the adherent cultivation unit is arranged on the bracket system and is connected with the speed regulating motor; the liquid supplement pipe is arranged above the adherent cultivation unit, and the liquid collection tank is arranged below the adherent cultivation unit; the liquid collection tank is internally provided with a liquid circulating pump, a liquid supplement device and a carbon supplement device; the liquid circulating pump is connected with the liquid supplement pipe through a pipeline; and the peripheral protection cover is arranged on the periphery of the bracket system and the adherent cultivation unit; and the top surface of the protection cover is made of a light-passing material. The device utilizes the principle of bright and dark flashing light to dilute the bright light and improve the utilization efficiency of luminous energy, thereby improving the yield of microalgae biomass.

Description

technical field [0001] The invention belongs to the field of microalgae cultivation, in particular to a microalgae semi-dry solid-state adherent culture device with alternating light and dark light Background technique [0002] Microalgae refers to aquatic planktonic algae capable of photosynthesis. Some microalgae are rich in protein and can be used as aquatic bait or livestock feed (such as spirulina). More importantly, some microalgae can synthesize a large amount of secondary metabolites under specific conditions, such as oils, carotenoids, polysaccharides, etc. These substances are often biologically active substances with high economic value and can be used in functional foods, Food additives, pharmaceuticals, bioenergy and other fields. In particular, extracting microalgae oil through large-scale cultivation of microalgae, and then transforming it into biodiesel is considered to be one of the most important ways to solve the problem of bioenergy production and carbo...
