Method for breeding microalgae in marine shoal region and microalgae breeding system

Abstract

The invention discloses a method for breeding microalgae in a sea shoal region and a microalgae culture system thereof. The method is characterized in that a plurality of seabed fixing piles are arranged in the marine shoal region to define a breeding area, in-water fixing ropes and overwater fixing ropes are connected among the fixing piles, a plurality of microalgae breeding plastic bags are connected between the in-water fixing ropes and the overwater fixing ropes, exhaust pipes are arranged on the upper side surfaces of the microalgae cultivation plastic bags, openings of the exhaust pipesare fixed to be upward by being connected to the in-water fixing ropes, the microalga breeding plastic bags are further provided with material pipes for feeding and discharging materials and are connected to air guide pipes through air inlet pipes, and the air guide pipes are connected with a fan. According to the method for breeding the microalgae in the sea shoal region and the microalgae breeding system, the area of a microalgae breeding water body is further expanded, breeding of the microalgae in the marine environment is realized, the influence of the environment on algae pollution is reduced, meanwhile, the microalgae is kept to not affect one another in the breeding process, the state is stable, and the economic benefits of the seaweed breeding industry are improved.

Description

technical field [0001] The invention relates to a method for cultivating microalgae, in particular to a method for cultivating microalgae in an ocean shoal area. The invention also relates to a microalgae cultivation system for carrying out the method for cultivating microalgae in said sea shoal area. Background technique [0002] Microalgae are a kind of autotrophic plants widely distributed in water bodies, rich in nutrients and high in photosynthetic utilization. They can use light energy and absorb CO through their efficient photosynthesis. 2 and H 2 O, convert them into organic matter such as carbohydrates, proteins, fats, and release O 2 . Polysaccharides, proteins, oils, pigments, etc. produced by cell metabolism make them 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 cultivation is mostly...

AI Technical Summary

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.

However, the use area of ​​seawater drying ponds is still relatively limited, and the promotion prospects and economic benefits are still unsatisfactory
