Description

technical field

[0001] The invention relates to the technical field of microalgae cultivation, in particular to a photobiological fluidized bed reaction device for wastewater treatment. 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, produce O2 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, as...
