[0014] The present invention provides a device for treating wastewater produced by reverse osmosis membrane production. It has the following beneficial effects:

[0015] 1. The equipment for treating wastewater produced by reverse osmosis membrane, when in use, passes wastewater into the water inlet pipe, the water in the water inlet pipe enters the oblique branch pipe, and enters the annular diverter pipe through the oblique branch pipe, the water in the annular diverter pipe enters the water outlet pipe, and is discharged from the water outlet pipe into the treatment tube.

[0016] 2. The equipment is used to treat wastewater produced by reverse osmosis membranes. When the sewage flows inside the annular diverter pipe, the water flow pushes the swing plate to move, and the swing plate drives the arc baffle to move through the connecting rod. The arc baffle rotates around the squeezing ball. During the rotation, the arc baffle gradually moves away from the discharge port. At this time, under the pressure of the air pressure inside the high-pressure gas cylinder, the treatment agent inside the storage box enters the ball shell through the discharge pipe, and enters the sewage inside the annular diverter pipe through the discharge port on one side of the ball shell, so that the treatment agent inside the storage box is automatically discharged through water flow control, without manual control, and is more convenient to use.

[0017] 3. For the equipment used to treat wastewater produced by reverse osmosis membranes, when the water flow rate is faster, the impact force of the water flow is greater, so the swing amplitude of the swing plate is also greater, thereby increasing the distance that the arc-shaped baffle rotates and moves away, making it easier to discharge more treatment agents, and the discharge amount of the treatment agent can be automatically controlled according to the water flow rate of the sewage.

[0018] 4. The equipment for treating wastewater produced by reverse osmosis membrane, when sewage is discharged from the outlet pipe, the water inside the outlet pipe enters the water collecting tray, the water inside the water collecting tray enters the outlet tray through the drain pipe, the water inside the outlet tray is discharged to the inside of the treatment tube through the outlet, when the sewage flows through the drain pipe, it drives the propeller inside it to rotate, the propeller drives the outlet tray to rotate through the transmission rod, the outlet tray drives the stirring rod to rotate, the stirring rod can be used to stir the water inside the treatment tube, so that the treatment agent and sewage can be fully mixed, the mixing effect is better, and at the same time, multiple groups of outlets are arranged, so that the sewage inside the outlet tray can enter the treatment tube from multiple different positions, and the outlet can rotate together with the outlet tray, so as to further improve the mixing efficiency of the treatment agent and sewage.
