The application discloses a nano-bubble enhanced reverse osmosis membrane system and an application method thereof, and belongs to the technical field of water treatment membrane separation. The system is composed of a nano-bubble generating and injecting module, a reverse osmosis membrane component and an online cleaning module. 10-200 nm negative nano-bubbles are prepared by ultrasonic cavitation or pressure dissolution method, and are uniformly injected into the water inlet end of the membrane after cyclone distribution. The functionalized membrane is modified by carbon nanotubes / metal organic framework and is decorated with a negative interface, and forms a double electrostatic repulsion layer with the nano-bubbles. Online cleaning is combined with ozone radical oxidation and gas-liquid pulse micro-jet physical peeling to realize drug-free membrane regeneration. The application solves the problems of traditional reverse osmosis membrane pollution, concentration difference polarization and high energy consumption through the synergistic effect of gas-liquid-membrane three phases, and is suitable for industrial production.

The invention discloses an efficient heat dissipation device based on non-Newtonian fluid and metal fins and a preparation method thereof.The efficient heat dissipation device comprises a sealing cover, a base and the porous metal fins, the sealing cover is internally provided with a containing cavity matched with the porous metal fins, the porous metal fins are arranged on the base, and the containing cavity is communicated with the base. The sealing cover covers the base, so that the sealing cover and the base form a sealed cavity structure, a working medium inlet and a working medium outlet are respectively formed in the sealing cover and are connected with an external liquid cooling circulation system, and a cooling working medium is a non-Newtonian fluid; according to the scheme, the non-Newtonian fluid is coupled with the porous fin structure, and the local viscosity of a working medium is actively regulated and controlled by utilizing a high shear field in the porous medium, so that the synergistic strengthening effect of low pump work and high heat exchange is realized.

The invention relates to the technical field of persimmon polyphenol extraction, and provides a green and environment-friendly method for extracting persimmon polyphenol from persimmons, and the green and environment-friendly method for extracting persimmon polyphenol from persimmons comprises the following steps: S1, taking persimmons as raw materials, cleaning, drying, crushing, adding a glacial acetic acid aqueous solution, adjusting the pH value to 4-5, adding an enzyme, mixing, and carrying out enzymolysis to obtain a mixed solution I; s2, after the mixed solution I is subjected to alcohol extraction and centrifugation, a liquid part is taken, and a mixed solution II is obtained; s3, adsorbing the mixed solution II with resin, adding an organic solvent for elution to obtain an eluent, and concentrating and drying to obtain persimmon polyphenol; in the step S2, enzymolysis comprises first enzymolysis and second enzymolysis, enzymes adopted by the first enzymolysis and the second enzymolysis are different, the enzyme adopted by the first enzymolysis is pectinase, and the enzyme adopted by the second enzymolysis is composed of hemicellulase and beta-glucosidase. According to the technical scheme, the problems of insufficient yield and purity of persimmon polyphenol extraction in related technologies are solved.
