Zusammenfassung:The invention discloses a method for filtering inorganic micro-nano particles with nano carbon fiber as a filter aid. The nano carbon fiber has a long fiber structure, high mechanical strength and good chemical stability, the surface of the fiber shows charged property, and coacervate of the fiber has porosity. When the nano carbon fiber is used as the novel filter aid, the nano carbon fiber has the characteristics of good permeability and strong particle absorption and interception ability, and can obviously improve the filtration efficiency of the inorganic micro-nano particles when applied to the filtration operation of the inorganic micro-nano particles. The application method for the nano carbon fiber filter aid is a general pre-coating or mixing means. The inorganic micro-nano particles can be metal oxides, nonmetal oxides, composite oxides or silicon-aluminum molecular sieves and can also be insoluble inorganic salts. The application scope of filtration of the substances includes the production process
