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

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...
