The application provides a preparation method of an ion complex and a supramolecular framework assembly, an artificial solid electrolyte interface phase and a zinc metal anode, and belongs to the field of supramolecular framework assemblies. The ion complex is prepared through ion interaction of a polyoxometalate cluster, coordination of zinc ions and cationic terpyridine and hydrogen bonding of grafted carboxyl groups, so that the three-dimensional SF is constructed in a good crystalline state. The three-dimensional growth of the framework of the ion complex is beneficial to improving the structural stability, while the unique performance is maintained. The ion complex can grow in situ on the zinc surface and further extend laterally to form a defect-free full coverage layer. Through dissolution and post-coordination effect, the 3D SF layer is used as an artificial solid electrolyte interface to improve the performance of the zinc anode. The clusters uniformly distributed in the nanopores of the ion complex form negatively charged nanochannels, which can accelerate the transfer of zinc ions and make the zinc deposition uniform.

The invention discloses a recovery treatment method of ammonium fluoride wastewater. The method comprises the following steps: firstly, separating ammonium ions from the ammonium fluoride wastewater in an ion exchange adsorption mode; and then, carrying out replacement reaction by utilizing a regeneration solution so as to transfer the ammonium ions into the regeneration solution. And then, controlling the pH value of the regeneration liquid subjected to the replacement reaction to be 10-11.5, so that the ammonium ions are converted into free ammonia. The pH-controlled regeneration liquid is then subjected to a stripping treatment to produce an ammonia-containing gas. And then, carrying out absorption treatment on the ammonia-containing gas to generate ammonia water. Therefore, the purposes of saving energy, reducing carbon and recycling waste can be achieved. The invention further discloses a recycling treatment system for the ammonium fluoride wastewater, which is used for implementing the steps.

The application discloses a salt-containing organic wastewater treatment device, a treatment system and a treatment method. The salt-containing organic wastewater treatment device comprises a shell, a separation pipe arranged in the shell and penetrating through the shell at both ends, an organic matter treatment unit comprising an organic matter adsorption layer and an organic matter desorption assembly, and an inorganic salt treatment unit comprising an electrode assembly, a pulse power supply and an inorganic salt discharge pump, and the two units are connected through a separation pipe separation channel. The application utilizes the principle of instantaneous enrichment of salt ions in the corresponding electric field by pulse electric adsorption-desorption, and enriches dissolved organic matter in water by the aid of modified fabric adsorption-ultrasonic desorption. When the pulse fluid provided by the liquid pump reverses the electric field in time, the instantaneous high-concentration salt ions in the field area are transferred out to expand the concentration difference, so that the salt component (or the organic component) in the high-salt-concentration material containing organic matter is gradually concentrated, and finally, the high-concentration organic wastewater is separated at low energy consumption and high flux to improve the value of the product.

Provided are layered gel-polymer electrolytes and electrochemical cells comprising these electrolytes as well as methods of forming the electrolytes and the cells. A gel-polymer electrolyte comprises a support core and one or two interface layers on the core surface. The interface layers are relied on to conform to electrode surfaces with high surface roughness, while the support core prevents any physical penetration and electrical shorts through the gel-polymer electrolyte, e.g., by electrode protruding peaks. Specifically, the interface layer redistributes around these protruding peaks and forms a continuous interface with the electrode surface. When the stack is compressed, the gel-polymer electrolyte also releases some liquid electrolyte, which soaks the electrode and enhances ionic transfer within the electrode and through the electrolyte-electrode interface. The gel-polymer electrolyte is formed by coating interface layers on the support core and soaking this assembly in a liquid electrolyte.
