The invention belongs to the field of environmental protection materials, and relates to a preparation method of easily recyclable nanometer antibacterial powder with multiple antibacterial effects. The antibacterial powder prepared by titanium dioxide with photocatalytic effect has a special tubular structure on the nanometer scale. Filtration and recovery of nanopowder provides the possibility. At the same time, the antibacterial metal ions loaded on the surface of the powder make the powder have both photocatalytic antibacterial and antibacterial functions of metal ions, realizing the dual antibacterial effect of the coexistence of two antibacterial methods. The material combines superior water suspension, wide bactericidal effect and simple recovery method, and can be widely used in the treatment of water microorganisms, solving the contradiction between the suspension and recovery of inorganic materials in the biological treatment of water. |
