▎ 摘　　要

NOVELTY - Zero-discharge treatment device comprises a shell (5) and sewage inlet pipe (1) is connected to the top side of the shell. A blocking plate (7) is connected to the middle position of shell. The shell is fixedly connected with graphene sponge under the blocking plate. The shell is fixedly connected with oil outlet pipe (3) on one side of graphene sponge. A top rod is slidably connected to the bottom middle position of shell. The top of the top rod is fixedly connected with a pressure plate and the bottom of the top rod is connected with an upper inclined rod. The bottom of the upper oblique rod is rotatably connected with a T-shaped rod. The bottom of the T-shaped rod is rotatably connected with lower oblique rod. The bottom of the lower oblique rod is connected with drive rod. The legs are connected to bottom of the shell. A connecting plate is fixedly connected to one side of middle position of shell and vertical rod is fixedly connected to the bottom of the connecting plate. USE - The device is useful for high-oil sewage. ADVANTAGE - The device: prevents grease in graphene sponge from being re-squeezed into the sewage during the upward movement of the pressure plate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the zero-discharge treatment device. Sewage inlet pipe (1) Oil outlet pipe (3) Shell (5) Blocking plate (7)
