Embodiment 1

[0066] The influence of embodiment 1 temperature and light intensity on the growth of spirulina

[0067] First prepare the following medium: 25.2g L -1 NaHCO 3 , 2.5 g L -1 NaNO 3 , 0.04g L -1 CaCl 2 2H 2 O, 1.0g L -1 K 2 SO 4 ,0.5gL -1 K 2 HPO 4 ,0.2g L -1 MgSO 4 ·7H 2 O,0.01gL -1 FeSO 4 ·7H 2 O,1.979gL - 1 MoCl 2 4H 2 O, 3.092 g L -1 h 3 BO 3 , 0.484g L -1 NaMo 4 2H 2 O, 0.23 g L -1 ZnSO 4 ·7H 2 O, 0.183 g L - 1NaVO 3 , 0.048g L -1 CoCl 2 ·6H 2 O, 0.2 g L -1 CuSO 4 ·5H 2 O.

[0068] The above-mentioned medium was injected into a rectangular tubular photobioreactor with a height of 10 cm, a width of 5.0 cm, and a length of 20 cm. The mixing of the reaction was provided by a rocker shaker with a speed of 60 rpm, and the shaker was set to continuous working mode. Then in this reactor, insert fresh Spirulina FACHB-314, and control final inoculation volume and inoculation density to be 200ml and 0.1g L respectively -1 . Finally, at 50, 20...

Embodiment 2

[0070] Embodiment 2 intelligent open pond cultivates spirulina

[0071] It is 2.0m2 that the 400L culture medium described in embodiment 1 is injected into the cultivation area 2 In the runway pool, the thickness of the liquid layer is 20.0cm after the culture medium is injected. The mixing of the culture solution in the open pool is driven by its stirring paddle, wherein the stirring paddle is connected with the controller of the intelligent mixing system through a data line, and operates under the instruction of the controller. In addition, the controller is also respectively connected with a light intensity meter and a thermometer for detection and acquisition of light intensity and temperature, wherein the measured temperature is the temperature of the culture solution. The controller will be used to control the rotation speed of the stirring paddle according to the data detected in real time and through a pre-programmed program. The control is based on the experimental r...

Abstract

The invention discloses a method for cultivating microalgae based on an artificial intelligence microalgae mixing system, and relates to the technical field of microalgae cultivation. The method realizes balanced management of mixing energy by measuring temperature and light intensity in real time to adjust mixing intensity. More importantly, the method can enhance the mixing efficiency at the optimum growth time with the saved energy, thereby further improving the production efficiency of microalgae. Therefore, the present invention can also ensure efficient growth of microalgae while reducing mixing energy consumption, and has great application potential.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to an artificial intelligence-based microalgae cultivation method. Background technique [0002] As a class of photosynthetic microorganisms, microalgae have the characteristics of fast reproduction, high photosynthetic efficiency, CO 2 It has the advantages of high fixation efficiency, rich in nutrients such as protein, polysaccharide, polyunsaturated fatty acid and pigment, etc., and it is easy to cultivate and does not occupy valuable cultivated land resources. Due to the above advantages, microalgae have great application potential in food, aquatic animal feed, bioenergy, sewage treatment, carbon emission reduction, etc., and it is the most favorable candidate to solve the current environmental, energy and food crises. [0003] An efficient and low-cost culture system is the key to promoting the large-scale industrial application of microalgae. At present, the c...
