Abstract

The invention provides a photo-bioreactor with a bionic fractal tree structure as well as application and a culture method thereof. The photo-bioreactor comprises a column reactor main body and sub reactors arranged inside the column reactor main body; each of the sub reactors adopts the bionic fractal tree structure and comprises a tubular trunk and multiple stages of tubular bifurcation branches connected with the upper part of the tubular trunk and communicated with the tubular trunk. The photo-bioreactor with the fractal tree structure and a circulating spray flow process is designed based on the theory of natural bionics and the optimal construction theory of fractal flow, and the light utilization rate and the flow performance can be effectively improved. In addition, in the circulating spray flow process, the higher temperature of an algae solution in a column and a tube is naturally reduced along with spray external circulation, and oxygen generated by photosynthesis is released, so that a photo-inhibition effect in the microalgae culture process is weakened, and the mass transfer process is also favorably enhanced by large-scale circulation. The photo-bioreactor provided by the invention is conductive to promotion of the microalgae carbon sequestration and improvement of the culture efficiency.

Description

technical field [0001] The invention belongs to the field of biochemical industry, and relates to a photogenetic reactor with a bionic fractal tree structure, an application and a cultivation method. Background technique [0002] Microalgae can convert CO through photosynthesis 2 And water is converted into various organic compounds (such as pigments, proteins, amino acids, vitamins and fatty acids, polysaccharides, etc.) that we need in life. Due to the high efficiency of light utilization and the ability of algae to quickly and efficiently absorb nutrients (such as CO2, nitrogen, phosphorus, etc.) from the surrounding environment and convert them into organic compounds, algae have great economic potential to solve food agriculture and energy crises in the future. At the same time, algae farming has a significant effect on CO 2 It is of great significance to improve the ecological environment such as fixing and sewage treatment. Although algae have high environmental and...
