This invention belongs to the field of water softening and sterilization technology, and discloses an ion-selective adsorption electrode, a micro-electric field adsorption system, and their application in water softening and sterilization / algae removal. An ion-selective adsorption electrode comprises polypolycarboxylate ion exchange fibers, activated carbon, a conductive agent, and a binder, wherein the mass percentage of the polypolycarboxylate ion exchange fibers is 5-20%. This invention uses CCEF-modified activated carbon as the cathode, and at the optimal doping level, it effectively removes Ca... 2+ and Mg 2+ The selectivity coefficients were 15.0 and 13.5, respectively, for Ca 2+ The electroadsorption capacity of the electrode is 311 μmol / g, which is much higher than that of the AC electrode. After 50 cycles of stability testing, the Ca... 2+ The electroadsorption capacity remained above 85%, demonstrating good regeneration ability. Activated carbon modified with nano-silver was used as the anode, and under electric field enhancement, the inhibition rates against bacteria and microalgae reached over 99% and 90%, respectively, exhibiting excellent antimicrobial contamination capabilities.

The application discloses a method for preparing an antibacterial nanofiltration membrane by using amikacin as a water-phase monomer, and belongs to the technical field of composite nanofiltration membrane preparation. The method uses amikacin as a water-phase monomer and adopts an interfacial polymerization method to prepare an antibacterial nanofiltration membrane (polyamide nanofiltration membrane). The method has the advantages of simple operation, mild reaction conditions and relatively low raw material cost. In addition, the prepared polyamide composite nanofiltration membrane has higher selective permeation performance and good antibacterial performance. The nanofiltration membrane flux can be as high as 20 L / (m 2 ·h·bar), and the tetracycline rejection rate can be as high as 99.3%. In addition, the application can also provide a reference for the preparation of other antibacterial interfacial polymerization separation membranes.
