▎ 摘　　要

NOVELTY - The pump unit structure has a pump structure that is provided with an L-shaped structure. Two ends of the pump structure are respectively provided with a water inlet (1) and a water outlet (2). A power assembly is provided in the pump structure. The power assembly is provided with a drive motor (3), a transmission (4) and a liquid discharge impeller. The drive motor is connected to the transmission and both drive motor and the transmission are arranged on outer casing of the pump structure. The rotating shaft is configured to extend into the pump structure and is connected with a liquid discharge impeller. A sewage filter screen (8) is arranged at water outlet. The sewage filter screen is arranged obliquely. A graphene oxide adsorption film is arranged on sewage filter screen. The concentrated sulfuric acid, ice bath are taken and stirred and graphite flakes and sodium nitrate are added, potassium permanganate is slowly added. The filter cake is washed with dilute hydrochloric acid. USE - Easy processing pump unit structure. ADVANTAGE - The adsorption efficiency is much higher than other adsorption materials. The film has good tensile strength and elongation at break and is not easily damaged in sewage. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the easy processing pump unit structure. Water inlet (1) Water outlet (2) Drive motor (3) Transmission (4) Sewage filter screen (8)
