A thin-film composite polyamide reverse osmosis membrane with anti-bacterial and anti-biofouling effects and a preparation method thereof are disclosed. The preparation method includes: dissolving a highly water-stable metal organic framework CuBTTri in an n-hexane solution containing trimesoyl chloride by ultrasonic wave, immersing a polyethersulfone ultrafiltration membrane in an aqueous solution of m-phenylene diamine and taking out, and then immersing the ultrafiltration membrane in the trimesoyl chloride-n-hexane solution containing the aforementioned metal organic framework for reaction and modification, so as to obtain the thin-film composite polyamide reverse osmosis membrane. The resulting composite reverse osmosis membrane integrated with the anti-bacterial metal organic framework CuBTTri has a high reverse osmosis membrane permeability and possesses greatly improved and persistent anti-bacterial and anti-biofouling properties. The preparation method is simple and conducive to promotion, and has mild conditions.
