The invention relates to a method for preparing a rod-like zinc oxide-based composite photocatalytic antibacterial water-based interior wall paint. The method comprises the following steps: preparing a zinc oxide-based composite photocatalytic particle precursor solution; mechanically stirring and uniformly mixing the precursor solution and the components of a water-based interior wall paint in sequence to obtain a mixed coating; and carrying out microwave reaction synthesis on the mixed coating to obtain the photocatalytic antibacterial water-based interior wall paint. The zinc oxide-based composite photocatalytic nanoparticles are dispersed in a form of a precursor mixed solution in the aqueous interior wall paint, so that the stability of the photocatalytic particles is better, the attached photocatalytic nanoparticles are uniformly dispersed on and coat the rod-like zinc oxide photocatalytic particles, the specific surface area is larger, more active sites are provided, and the antibacterial and sterilizi
