Large photobioreactor floating in wide water area

Abstract

The invention relates to a large photobioreactor floating in a wide water area. The large photobioreactor is used for culturing microalgae in the wide water areas, such as oceans / lakes and the like, and comprises a carrying floating platform floating on the water surface and a microalgae culture device suspended below the carrying floating platform, and the microalgae culture device is immersed in water; the microalgae culture device is an incubator with an open top surface and closed films at the periphery and the bottom, and microalgae cells are inoculated and cultured in the incubator; an artificial light source and a nutrition supply device are arranged in the incubator; and a storage tank for providing nutrition for the nutrition supply device is arranged on the carrying floating platform. The photobioreactor disclosed by the invention does not occupy land area, is large in culture volume, low in cost, low in energy consumption and high in light energy utilization rate, and opens up a new research and development direction of a water floating photobioreactor.

Description

technical field [0001] The invention relates to the technical field of photobioreactors, in particular to a marine pasture photobioreactor. Background technique [0002] Microalgae can efficiently use light energy, carbon dioxide and water for photosynthesis, produce oxygen and synthesize a variety of biologically active substances (such as polysaccharides, proteins, oils, unsaturated fatty acids, natural pigments, vitamins and minerals, etc.), and have a growth rate Fast, short cultivation cycle, sustainable regeneration, no occupation of cultivated land and other advantages, it is considered as an important source of raw materials for new biomass energy, and can be widely used in food feed, medicine and health care, cosmetics, aquatic animals and poultry and livestock breeding, etc. Very broad application prospects. [0003] Photobioreactor is the core of the whole microalgae industry chain. At present, the large-scale cultivation of microalgae for the purpose of commerc...

AI Technical Summary

Problems solved by technology

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a large-scale photobioreactor floating in wide waters, which combines the advantages of various reactors and the characteristics of microalgae growth, and solves the problem that current terrestrial photobioreactors occupy. Problems such as wide area, high cost, high energy consumption, difficult temperature control, low utilization rate of light energy, slow cell proliferation, low biomass concentration, and easy pollution have opened up a new direction for the research and development of marine photobioreactors.
