[0023] The driving structure 5 includes a first motor 51, a driving wheel 52 and a driven wheel 53. The first motor 51 is arranged on the surface of the sedimentation tank 1. The output shaft of the first motor 51 is fixed to one side of the driving wheel 52. The driving wheel 52 is connected to the driven wheel 53 through a belt. The interior of the driving wheel 52 and the driven wheel 53 are respectively fixed to one end of the two rotating rods 3. In this way, when the two rotating rods 3 are driven to rotate, the first motor 51 can be started, and the driving wheel 52 can be driven to rotate. At the same time, the driven wheel 53 is driven to rotate through the belt, and the two rotating rods 3 are driven to rotate.

In order to improve the subsequent phosphorus removal effect, the movable plate 15 and the scoop frame 7 can be driven to move upward by the force structure 9 to scoop up the suspended matter and impurities.
