Description
Technical Field
The invention relates to the field of water treatment, in particular to light supplementing equipment and a light supplementing method for a microalgae reactor.
Background
Mixing and illumination are two important factors in the design of microalgae photoreactors. The mixing conditions in the reactor directly influence the distribution of the algae cells and the dissolution and diffusion of the nutrient salts. And the illumination is a necessary condition for the photosynthesis of algae cells. The luminous flux decays exponentially as the position within the photoreactor increases in distance from the illuminated side. In addition, since triacylglycerols are rapidly metabolized only in the dark, dark conditions have an indispensable effect on photosynthesis and growth of microalgae, but a prolonged period of darkness leads to consumption of biomass due to respiration. On the other hand, long-term strong light irradiation produces photoinhibition on the PSII part of the photosynthetic electron transport chain. Once the light energy absorbed into the reaction center exceeds its consumption, the photosynthesis module is damaged. Therefore, having alternate light-dark cycles for the algal cells facilitates the growth of microalgae, the so-called flash effect. A good microalgae photoreactor should have good mass transfer mixing conditions and fast light dark cycle of the algae cells.
In the existing microalgae photoreactor structure, a set of light illumination system and a set of stirring system are generally required to be respectively arranged, so that the use cost is high, and a set of circulating system is required to be arranged to enable the microalgae to perform light-dark circulation between light reaction and dark reaction in consideration of the flash effect of the microalgae, so that the cost of microalgae culture setting and the system complexity are increased.

Because all be provided with luminescence unit 1 and flash of light drive assembly 3 in upper ledge 21 and the lower ledge 23, consequently can guarantee that little algae liquid has the illumination of two upper and lower directions to carry out the light filling in vertical direction, the technical problem of the light intensity decay that only sets up a top light filling unit and cause has been avoided, simultaneously owing to set up vertical board 3212 that is used for stirring algae liquid on flash of light drive assembly 3, make algae liquid can realize continuous even stirring in the dark circulation of light, the light filling effect of algae liquid light filling has been improved, make algae liquid receive illumination more abundant.
When the flash driving component 3 is started, the driving motor drives the hollow shaft 41 of the sampling unit 4 to rotate, and simultaneously drives the driving ring 31 of the flash effect component to rotate, so that the liquid pump is synchronously started within initial 10 seconds after the flash driving component 3 is started, so that the sampling unit 4 can extract a certain amount of algae liquid through the hollow shaft 41, and the hollow shaft 41 rotates while extracting the algae liquid, thereby ensuring the uniformity of algae liquid sample extraction. The extracted algae liquid and the algae liquid index are conveyed to the corresponding algae liquid index detection unit, the index of the algae liquid is detected, the opening and closing frequency of the flash driving assembly 3 is determined according to the detected index, namely the forward and reverse rotation frequency of the driving motor, the light and dark circulation frequency of the algae liquid is controlled, and the algae liquid is in the best growth condition.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and amendments can be made without departing from the principle of the present invention, and these modifications and amendments should also be considered as the protection scope of the present invention.
