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 cultured in pipeline photobioreactors or bioreactors composed of small systems are that the walls of the pipeline are easily adhered by algae cells, resulting in decreased light transmittance, unstable temperature and difficult cleaning during the cultivation period. Only suitable for small-scale production in the laboratory
[0004] The current culture reaction device has poor adaptability to the growth of Haematococcus pluvialis, and cannot provide flexible and controllable light conditions, temperature conditions and acid-base corresponding mechanisms, which seriously affects the growth and biomass accumulation of Haematococcus pluvialis the quantity and quality of

Description

technical field [0001] The invention belongs to the technical field of algae cultivation equipment, in particular to an algae cultivation photobiological reactor and a continuous cultivation reaction system containing the same. Background technique [0002] Microalgae is a kind of autotrophic plant with rich nutrition and high photosynthetic utilization. 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 in the ocean. , medicine, genetic engineering, liquid fuel and other fields have broad development prospects. Microalgae grow fast and have strong environmental adaptability, so they can be self-cultured for photosynthesis in photobioreactors. Haematococcus pluvialis is a single-celled green algae. Under the conditions of nitrogen deficiency, phosphorus or strong light energy, astaxanthin in the cells of Haematococcus pluvialis will accumulate i...
