This application relates to the field of swimming pool disinfection equipment technology, and in particular to a portable swimming pool disinfection dispenser, which includes a feeding assembly, a spraying assembly, a buoyancy device, a drive device, and a direction-changing assembly. The medicine storage tank is equipped with a dosing channel, and the buoyancy device surrounds the medicine storage tank to ensure buoyancy. The spraying assembly uses wind power via a guide vane to rotate the diffusion chamber, achieving uniform dispersion of the disinfectant. This application enhances stability and uniform dispersion of the disinfectant through the design of a rotary bearing, sealing ring, and regulating valve. Simultaneously, the use of wind power to drive the guide vane and rotate the diffusion chamber enables rotation control and convenient operation. This application solves the problems of complexity and high cost of existing equipment, providing a lightweight and economical swimming pool disinfection solution suitable for home and small swimming pool scenarios.

The application discloses a monovalent cation selective separation membrane and a preparation method thereof, and belongs to the technical field of ion exchange membranes. A bisamine monomer and an acyl chloride monomer are respectively dissolved in water and n-hexane to obtain an aqueous solution and an oil solution. A porous base film is fixed in the middle part of a central channel of a diffusion device, the aqueous solution and the oil solution are respectively poured into diffusion chambers on the upper and lower sides of the central channel, interfacial polymerization is carried out, then the membrane is taken out, washed with n-hexane, dried, and a monovalent cation selective separation membrane is obtained. The preparation method of the monovalent cation selective separation membrane has the advantages of low raw material cost, mild preparation conditions and simple operation, so that the membrane preparation cost can be greatly reduced, and the existence of chloromethyl on the membrane makes the polyamide structure more stable. Meanwhile, the electrodialysis Na + / Me4N + , K + / Me4N + Separation performance of the prepared monovalent cation selective separation membrane is superior to that of a commercial CIMS membrane, and has a wide application prospect in the fields of electronic-grade TMAH purification preparation and the like.
