An umbrella-shaped tower-type photobiological cultivator

Abstract

The invention discloses an umbrella-shaped tower type photobiological culture device and belongs to the technical field of microalgae culture. The umbrella-shaped tower type photobiological culture device comprises a wastewater fermentation tank, a culture solution tank, a culture device and a water treatment tank, wherein the wastewater fermentation tank is used for stirring and fermenting wastewater to obtain a microalgae culture solution; the culture solution tank is communicated with the wastewater fermentation tank through a filter and is used for storing the microalgae culture solution and carrying out microalgae inoculation; the culture device comprises a shaft frame; the shaft frame is vertically mounted on a working plane; the shaft frame is provided with a plurality of umbrella-shaped culture units in sequence from big to small according to a height progressively increasing shape; the culture units are light guide plates for forming an umbrella shape; a horizontal solution storage groove is formed in the top of the shaft frame; the solution storage groove is connected with a submersible pump located in the culture solution tank through a liquid inlet pipe; an annular water collection groove is formed in the edge of the culture unit located at the bottommost side of the shaft frame and the water collection groove is communicated with the culture solution tank; the water treatment tank is internally provided with a water filtering unit and a water inlet is connected with the culture solution tank; a water outlet is arranged at one end relative to the water inlet. The umbrella-shaped tower type photobiological culture device combines microalgae culture and microalgae domestication, sewage treatment, biological carbon fixation and microalgae recycling and realizes integration of microalgae culture.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to an umbrella-shaped tower photobiological cultivation device. Background technique [0002] Microalgae are photoautotrophic organisms that are widely distributed in fresh water, oceans and various soils on the earth. They have the characteristics of rapid growth, high photosynthetic efficiency, strong adaptability, and asexual reproduction. Microalgae can use light energy, CO2, organic carbon in wastewater, ammonia nitrogen, organic phosphorus and other substances as carbon sources, nitrogen sources and phosphorus sources, and absorb heavy metals to purify wastewater; they can also absorb CO2 and other gases in the atmosphere as their own metabolic carbon source, producing O2 to fix CO2 to purify the air; at the same time, microalgae contain a variety of high value-added bioactive substances, such as polyunsaturated fatty acids, algae polysaccharides, phycocyanin, a...

Problems solved by technology

[0007] At present, the research direction is mainly to explore the cultivation method of microalgae, which is mainly to blindly enhance the light intensity and couple the microalgae culture with various ratios of wastewater. There are relatively few studies on aesthetics and biological carbon fixation. Therefore, it is necessary to propose an umbrella-type tower photobioreactor to realize automatic adjustment of light intensity and enhance the efficiency of biological carbon fixation, thereby purifying air and sewage.
