▎ 摘　　要

NOVELTY - The device has a fixed flat head screw (16) that is connected to both sides of an inner wall of a hybrid decomposition chamber (11). A fixed support frame is connected to both ends of the fixing flat head screw. A stirring motor (18) is connected to both ends of a fixed support frame (17). A stirrer (19) is connected to a lower end of stirring motor. A right end of stirrer is connected with a second flow meter (20) and a second valve (21). A water collection tank (23) is connected to a right end of the second valve. A top end of the water collection tank is fixed with a water collection tank liquid inlet (22) and a silicone water pipe (6). A total processor (26) and a first valve (5), a constant flow pump (7), an ultrafiltration membrane filter tank (10), a mixing decomposition chamber (11), an annular ultraviolet lamp tube (14), and a disinfection solution box, an inlet/outlet valve (15), a pressure temperature sensor (25), a stirring motor (18) and the second valve are connected. USE - Device for treating wastewater based on graphene oxide quantum dot modified polysulfone ultrafiltration membrane. ADVANTAGE - The purified treatment of wastewater can be highly achieved. The antifouling performance of the ultrafiltration membrane is improved and costs are saved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for treating wastewater.
