▎ 摘　　要

NOVELTY - The device has a second cabin (2) and a first cabin (1) whose connecting portion is provided with a partition (201) whose top surface is lower than the top surfaces of the first cabin and the second cabin. A motor (3) with a timing belt (5) on the action shaft is installed on the side wall of the first cabin. The inner surface of the timing belt is provided with an inner tooth surface (502), and the side wall of the first cabin is provided with a displacement seat (4). The side rods (1002) are welded at both ends of a scanning sheet (10), and the bottom of the side rods is welded on the inner wall of the first cabin. A take-off board (101) whose top surface is in contact with the side rod, and the take-off board is arranged inclined upward along the height direction of the first cabin. USE - Graphene production wastewater treatment device. ADVANTAGE - The floating objects that are surging are also cleaned up when the sweeping film cleans the upper layer of the sewage, which improves the functionality. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene production wastewater treatment device.
