[0014] In this embodiment, the brush plate is provided with a screw hole capable of cooperating with the screw thread.

[0015] Beneficial Effects

[0016] The utility model provides a water pollution prevention and control device. Compared with the prior art, it has the following beneficial effects:

[0017] (1) The water pollution control device is constructed by setting up a frame on both sides of the sewage channel so that the filter screen in the middle faces the flowing sewage. When the sewage passes through the filter screen, the stepper drive motor is started, and the stepper drive motor drives the main rotating rod to rotate. The main rotating rod drives the auxiliary rotating rod to rotate synchronously through the transmission structure formed by the first gear and the transmission chain, and then drives the two sets of rollers to retract and release the connected filter screen.
