Problems solved by technology

The main problems in the large-scale cultivation of microalgae in the natural environment are: high radiation intensity and temperature in summer, low radiation intensity and temperature in winter, and the natural environment cannot meet the growth conditions of microalgae and keep them within their adapted radiation and temperature ranges
In addition, due to light shading, the highest culture concentration and the depth of the microalgae culture tank are limited, which reduces the utilization efficiency of the culture tank
[0006] At present, there is no research report on how to couple light energy and temperature in the natural environment and thus improve the production of microalgae in the existing technology.

Embodiment 1

[0038] Embodiment 1 is suitable for the spirulina carbon fixation method of high-irradiance high-temperature natural environment conditions

[0039] A reflective film with a reflectance of 80-90% is pasted on the surface of the concentrating reflector. The angle between the incident light of sunlight and the concentrating plate is 35-45°, the length of the concentrating plate is 1:1 to the length of the microalgae pond, and the ratio of the width to the width of the reflecting plate is 1:1.
