The first motor rotates to make the connecting shaft 5 drive the stirring frame 9 to rotate, so that the raw materials in the reactor 1 are stirred and mixed, and at the same time, the connecting shaft 5 rotates to make the cam 3 rotate, so that the cam 3 squeezes the first filter plate 6 to move downward along the guide rod 8, and the first spring 7 contracts. When the cam 3 separates from the first filter plate 6, the first spring 7 rebounds and stretches, so that the first filter plate 6 moves upward and resets, and this cycle is repeated, thereby making the filtering effect of the first filter plate 6 more efficient and avoiding the first filter plate 6 from being easily blocked. Then, the waste water after the primary filtration enters the semicircular pipe 33 in the sedimentation tank 2 through the connecting pipe, and flows into the sedimentation tank 2 through the water hole 34, and the reduction motor is started. The reduction motor rotates to make the connecting frame 35 rotate to The wastewater and the reaction material are further stirred, so that the suspended matter in the liquid floats on the surface of the wastewater. At this time, the second filter plate 29 filters the floating matter. At the same time, the gear 19 rotates to make the gear ring 18 drive the second protrusion 21 on the rotating frame 17 to rotate, so that the second protrusion 21 pushes the connecting block 22 to move downward, thereby making the T-bar 13 move downward and pull the turntable 10 to rotate through the fixed column 12, and the second spring 16 contracts, thereby making the baffle 31 rotate and open, and at the same time, the T-bar 13 moves downward to make the block 28 clamp the limit block 23 through the limit groove 24, so that the position of the T-bar 13 at this time is maintained, thereby making the floating matter enter the other half of the space of the sedimentation tank 2 separated by the baffle 31, and then the rotating frame 17 continues to rotate to make the first protrusion 20 squeeze the block 28 and separate from the limit block 23, at this time, the second spring 16 rebounds and stretches, so that the T-bar 13 drives the turntable 10 to rotate in the opposite direction, thereby resetting the baffle 31, and so on.
