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 by pipeline photobioreactors or bioreactors composed of small-scale systems are that the pipe wall is easily adhered by algae cells, resulting in decreased light transmittance, unstable temperature and difficult cleaning during cultivation. Only suitable for small-scale production in the laboratory
[0004] The current culture reactor 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

Abstract

The invention relates to a microalgae culture photobioreactor and a continuous culture reaction system containing the same. The microalgae culture photobioreactor comprises a closed reactor tank body,and is characterized in that the closed reactor tank body is internally provided with a waterproof LED lamp, and the waterproof LED lamp includes a light-emitting part, a sealed-arranged transparentlamp cover and a drive controller; the light-emitting part is provided with LED light-emitting chips, and the single LED light-emitting chip can simultaneously emit a number of light with different wavelengths; and the light-emitting part is arranged inside the transparent lamp cover, and the drive controller is arranged outside the closed reactor tank body and can control the energy of the lightwith different wavelengths to be increased or decreased at the same time.

Description

technical field [0001] The invention belongs to the technical field of algae cultivation equipment, and in particular relates to a microalgae 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 w...
