Description

Technical Field

[0001] The invention belongs to the technical field of microalgae cultivation, and specifically relates to a device and a method for culturing microalgae in graded domestication of high-concentration wastewater. Background Art

[0002] The combination of microalgae cultivation and wastewater treatment provides a promising strategy to reduce the cost of wastewater treatment. Cultivating microalgae with various wastewaters not only removes nutrients from the wastewater, but also reduces the cost of cultivating microalgae and produces large amounts of biomass for further use. Although the use of microalgae to remove pollutants is promising, it is not ideal for treating high-concentration wastewater. High-concentration wastewater often contains a large amount of organic matter, inorganic salts, heavy metals, and other toxic and hazardous substances. These substances are of various types and have different properties, which makes wastewater treatment more difficult. How to apply microalgae to treat high-concentration wastewater and produce high-value products at the same time has become a challenge.

[0003] Studies have found that domestication can enhance the resistance of microalgae to pollution and their ability to adapt to the environment, significantly enhance the biomass production of microalgae in wastewater and the removal of nutrients, and is an effective solution to the problem of low efficiency. However, the current graded domestication and cultivation equipment cannot clean the reaction tank during domestication and cultivation, and manual cleaning is required, which is inefficient. In addition, multiple reaction tanks are required for cultivation during graded domestication. The equipment is relatively large and difficult to clean and maintain. In addition, when injecting materials into the reaction, the injected materials cannot be mixed and diluted in advance. The materials are directly injected into the reaction tank, and then the diluent is injected, resulting in excessive local concentration, which affects domestication and cultivation.
