Problems solved by technology

[0003] At present, the large-scale cultivation of Haematococcus pluvialis mainly adopts racetrack culture ponds using outdoor natural light. The main factors hindering the large-scale production of Haematococcus pluvialls are biological pollution and population growth during the cultivation process of Haematococcus pluvialis. Low density leads to low output per unit area, resulting in high cost
The defects of Haematococcus pluvialis cultivated by pipeline photobioreactor or bioreactor composed of small-scale system are that the pipe wall is easily adhered by algae cells, which leads to the decrease of light transmittance, unstable temperature and difficulty in cleaning during the cultivation period. Only suitable for small-scale production in the laboratory
[0004] At present, there are few closed algae cultivation devices and their functions are not complete. In particular, there are few studies on closed reactors suitable for large-scale cultivation of Haematococcus pluvialis. How to provide energy suitable for Haematococcus pluvialis, especially How to meet the needs of algae for light energy and heat energy during large-scale algae cultivation, so as to improve the quantity and quality of algae cultivation, has always been a problem studied by those skilled in the art

Description

Technical field [0001] The invention belongs to the technical field of algae cultivation equipment, and specifically relates to an algae cultivation photobioreactor. Background technique [0002] Microalgae is a kind of autotrophic plant with rich nutrients and high photosynthetic availability. Its biomass contains a variety of biochemical substances, such as polysaccharides, proteins, oils, carbohydrates, pigments and other substances. It is widely distributed on land and sea, and is used in food , Medicine, genetic engineering, liquid fuel and other fields have broad development prospects. Microalgae grow fast and have strong environmental adaptability. They can be used for photosynthetic self-cultivation in a photobioreactor. Haematococcus pluvialis is a single-celled green algae. Under the conditions of lack of nitrogen, phosphorus or strong light energy, astaxanthin in the cells of Haematococcus pluvialis accumulates in large amounts. Natural Astaxanthin is one of the stro...
