description The invention provides a heterojunction micron box composite photocatalyst as well as a preparation method and application thereof. The method comprises the following steps: S1, preparing a Fe2O3 micron box; S2, preparing a Fe2O3/BiVO4 heterojunction micron box composite photocatalyst: dissolving Bi(NO3)3.5H2O in ethylene glycol, stirring particles evenly, adding the Fe2O3 powder prepared in the step S1 so as to obtain a mixed test solution 1, stirring and then standing; dissolving NH4VO3 in the ethylene glycol, slowly adding into the mixed test solution 1, and stirring to obtain a mixed testsolution 2; dissolving urea in the ethylene glycol, slowly adding into the mixed test solution 2, placing in a hot water bath for a certain period of time, and then standing; carrying out centrifugation and impurity removal treatment, then drying, and collecting solid to obtain the Fe2O3/BiVO4 heterojunction micron box composite photocatalyst. The aim of degrading antibiotic wastewater by using the Fe2O3/BiVO4 heterojunct
