The invention discloses an anodic treatment method for metal surface patterning , which is applicable to a metal object, and the steps of the anodic treatment method comprises: providing an electrolytic tank for storing the electrolyte, wherein the electrolyte comprises an inorganic acid agent and a biological bacteria; then placing the metal object, the target, and the graphic member having the predetermined pattern into the electrolytic tank such that at least a portion of the metal object, the target and the graphic member contacts the electrolyte. The metal object and the graphic member are electrically connected to the positive pole of the power supply, the target is electrically connected to the negative pole of the power supply, and an operating voltage is applied by the power supply to polish and form an oxide layer on the surface of the metal object. The surface of the metal object forms a three-dimensional pattern corresponding to the preset shape of the graphic member. The invention also discloses
