The invention relates to a method for preparing a rod-like titanium dioxide-based composite photocatalytic antibacterial water-based interior wall paint. The method comprises the following steps: preparing a titanium dioxide-based composite photocatalytic particle precursor solution; mechanically stirring and uniformly mixing the precursor solution and the components of the 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 rod-like titanium dioxide-based water-based interior wall paint. The titanium dioxide-based composite photocatalytic nanoparticles are dispersed in the water-based interior wall paint in the form of a precursor mixed solution, so that the photocatalytic particles are better in stability, better in dispersity and not prone to agglomeration, the attached photocatalytic nanoparticles are uniformly dispersed on and coat the rod-shaped titanium dioxide photocatalytic particles, the specific surf
