Problems solved by technology

However, this internal component lacks the effect of making the fluid move in a continuous cycle in the direction of light attenuation, and cannot enhance the mixing of fluid in the direction of light, and the ability to improve the ability of algae cells to receive light is limited.

Embodiment 1

[0074] Embodiment 1: Comparison of the photoautotrophic culture process of chlorella in the new flat plate reactor and the control reactor

[0075] Fill 14L tap water into 3 flat-panel photobioreactors with different internal components and 1 control reactor respectively, add 2ml sodium hypochlorite solution (available chlorine content 10%), after ventilating and mixing, treat for 12 hours, then add sulfur Sodium sulfosulfate neutralizes the remaining sodium hypochlorite, and after checking with potassium iodide starch test paper, it is determined that there is no sodium hypochlorite (generally excessive sodium thiosulfate), continue aeration for a period of time to oxidize the excessive sodium thiosulfate, and then put microalgae in the reactor The photoautotrophic culture medium (f / 2 medium) was fully mixed and then added with Chlorella pyrenoidosa seeds, and the photoautotrophic culture started. The initial algal cell density is about 0.15g / L, the ventilation rate is 1.0vvm...

Abstract

The present invention provides a novel photobioreactor and an internal component thereof. The photobioreactor comprises a transparent housing and multiple regularly arranged transparent baffle plates. The baffle plates are axially placed in the housing and tilt horizontally. A trapezoidal partial space is formed between the baffle plates. The photobioreactor enables fluid in a central area (dark area) of the reactor and fluid in a surface area (light area) of the reactor to rapidly and periodically circulate, thereby enhancing mixing of fluid along a radial direction (light direction) of the reactor.

Description

technical field [0001] The invention belongs to the field of microalgae biotechnology, and relates to a novel photobioreactor and its internal mixing components, which can realize high-density and high-yield culture of microalgae. In addition, the present invention can also be used in other cultivation or chemical reaction fields that require light (such as photosynthetic bacteria cultivation, plant cell cultivation, photocatalytic reaction, etc.). Background technique [0002] Microalgae are rich in protein, polysaccharides, polyunsaturated fatty acids and carotenoids and other high value-added substances. At the same time, microalgae have the ability to absorb N / P elements and accumulate oil during the cultivation process. Therefore, microalgae are important in bioenergy. , Biological carbon sequestration, environmental protection, food, feed and medicine and many other aspects have a wide range of applications. Especially in recent years, in terms of bioenergy, microalga...
