This real work is a flexible ozone fiber filler catalyst prepared by using PVDF fiber membrane as the carrier and loading efficient active substances. During the ozonation process, the catalyst can accelerate ozone decomposition and enhance catalytic activity, thereby improving the removal efficiency of refractory pollutants such as antibiotic residues. Compared with traditional ozone catalysts, this fiber catalyst offers lower cost, longer service life, reduced energy consumption, simple structure, and industrial scalability, providing an innovative solution for practical water treatment.
(1) Through static reaction experiments and dynamic ozonation experiments, the selected catalyst materials were tested in terms of catalytic activity, mechanical strength, stability, and other aspects, so as to determine the final loading method and active substances suitable for the fiber filler structure.
(2) A flexible fibrous catalyst structure was designed, enabling it to give full play to the advantages of large specific surface area and porous structure, thus improving the utilization efficiency of ozone and the effect of catalytic reaction.
(3) An appropriate combination method of active substances and PVDF fiber membrane was selected to complete the physical preparation of flexible ozone fiber fillers. This catalyst can be recycled within a certain cycle and has shown a significant enhanced degradation effect in water treatment experiments.
