Method for breeding microalgae in salt airing pond and microalgae breeding system

Abstract

The invention discloses a method for breeding microalgae in a salt airing pond and a microalgae breeding system. The method is characterized in that a porous mesh is arranged under the liquid surfaceof the interior of the salt airing pond, and a plurality of transparent microalgae culture plastic bags connected to an air supply pipeline are arranged below the porous mesh; an exhaust pipe is arranged on the upper side face of each microalgae culture plastic bag and fixedly opened upward; the microalgae culture plastic bags are also provided with material pipes for introducing or discharging algae seeds, algae liquid, sea water, nutrient solutions and a disinfectant. According to the provided method for breeding the microalgae in the salt airing pond and the microalgae breeding system, thearea of microalgae culture water is greatly expanded, breeding of the microalgae in a marine environment is achieved, the impact of algae pollution on the environment is relieved, and the economic benefits are increased.

Description

technical field [0001] The invention relates to a method for cultivating microalgae, in particular to a method for cultivating microalgae in a salt drying pond. The present invention also relates to a microalgae cultivation system implementing the method for cultivating microalgae in a salt drying pond. Background technique [0002] Microalgae are a type of autotrophic plants that are widely distributed on land and in the ocean, are rich in nutrients, and have high photosynthetic utilization. They can use light energy and absorb CO through their efficient photosynthesis. 2 and H 2 O, convert them into chemical energy such as carbohydrates, proteins, fats, etc., and release O 2 . The polysaccharides, proteins, and pigments produced by cell metabolism have good development prospects in the fields of food, medicine, genetic engineering, and liquid fuels. [0003] There are many kinds of microalgae and the individuals are generally smaller than 2mm. At present, microalgae c...

Problems solved by technology

However, this culture method has the following disadvantages: 1. Since microalgae culture requires sufficient light, measures such as increasing the depth cannot be used to develop the culture water body, so the floor area is large, and the breeding place is limited, making it difficult to realize large-scale and large-scale culture.

2. The land environment is poor, and it is easy to pollute the cultured microalgae; 3. This culture method is only suitable for a small number of microalgae that survive in extreme environments such as high salinity and high alkalinity, and the types of cultured microalgae are limited.
