The brush 8 is arranged in the rotary space 20 and extends along the first direction, is located below the inner slag groove 5 and is separated from the inner slag groove 5, and is used to clean the side of the grid plate 3 facing the rotary space 20. The brush driving member 9 is electrically connected with the control module, and is used to drive the brush 8 to rotate. The brush driving member 9 can be a driving motor.

[0054] Specifically, as shown in Figure 1 and Figure 2 , the rotary drive device 4 further comprises a rotary sprocket 41, and the rotary sprocket 41 is engaged with the rotary chain 2.

As shown inFigure 5 As shown in the figure, the bottom of the frame 1 is provided with a pair of guide rails 102 opposite to each other in the first direction, and a pair of rotating chains 2 correspond to the pair of guide rails 102 respectively, and each rotating chain 2 rotates along its corresponding guide rail 102. Among them, the first direction is Figure 1 The arrow A is the direction. During the rotation of the grid plate 3 driven by the rotating chain 2, the sewage flows through the grid plate 3, and the grid plate 3 drives the sundries in the sewage to fall from the top into the inner slag groove 5, and the sundries are washed into the sewage discharge channel 51 by the water in the water flow channel 52. In addition, as Figure 1 And Figure 7 As shown in the figure, the top of the grid sewage treatment equipment 100 also has a spray head 101, which can flush the sundries on the grid plate 3 into the inner slag groove 5.
