The system comprises a middle chamber, a left lateral chamber and a right lateral chamber and is characterized in that the left lateral chamber and the right lateral chamber are disposed on left and right sides of the middle chamber, respectively, an anion exchange membrane and a cation exchange membrane are disposed between the middle chamber and the left lateral chamber and between the middle chamber and the right lateral chamber, respectively, both the bottom of the left lateral chamber and the bottom of the lateral chamber are provided with liquid inlets, both the top of the left lateral chamber and the top of the right lateral chamber are provided with liquid outlets, micro-algal culture liquid is disposed in the middle chamber, the top center of the middle chamber is provided with a gas outlet, an exhaust pipe is inserted into the middle chamber through the gas outlet, both the left and right ends of the top of the middle chamber are provided with aeration holes, and a first aeration pipe and a second aeration pipe are inserted into the middle chamber respectively through the aeration holes. The adaptive micro-algal photo-biological reaction system and method is widely applicable to the fields such as biology, environment protection and energy.

Description

technical field [0001] The invention relates to a photobiological reaction system and method, in particular to an adaptive microalgae photobiological reaction system and a method for automatically replenishing nutrients. Background technique [0002] Under the background of environmental pollution and energy shortage, microalgae, as a single-celled microorganism, can use carbon dioxide in power plant exhaust gas as a growth substrate to produce fatty acids and proteins through its own biochemical metabolic reactions while reducing carbon dioxide emissions. , vitamins, DHA and many other high value-added products. Among them, fatty acids can be converted into biodiesel through transesterification, which alleviates the pressure of energy shortage to a certain extent; and proteins, vitamins, DHA and other substances can be further processed into biomedicine and nutritional products that are of high value to humans. Therefore, microalgae have received more and more attention be...

Problems solved by technology

Under this culture mode, if appropriate nutrients are added in the early stage (i.e., more media such as SE and BG11 are currently used), with the increase in the concentration of microalgae biomass and the consumption of nutrients, the growth rate of microalgae will decrease during the growth of microalgae. Lower nutrient substances in the later stage will have a more serious growth restriction; and if a large amount of nutrient substance is added at one time in the early stage, it will have a strong growth inhibitory effect on the low concentration of microalgae in the early stage
