[0023] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0024] Embodiment: First, the sewage is introduced into the pool 1, and the sewage flows. The first motor 3 is turned on to start the rotating shaft 2. The rotation of the rotating shaft 2 drives the filter frame 4 to make a circular motion. The two ends of the plug plate 5 are inserted into the notches 401 in the filter frame 4, and then one end of the bolt 403 is inserted into the pin hole 503 to complete the assembly of the plug plate 5 and the filter frame 4. The first pointed cone 502 and the second pointed cone 7 on the plug plate 5 and the arc plate 6 will hook and grab the debris in the sewage, and the sewage flows into the filter from the second through hole 501. The lower end of the frame 4 passes through the first through hole 402. When a certain number of debris are hooked, the rotating shaft 2 rotates, and the next filter frame 4 rotates to the lower end of the pool 1 for filtering. The staff processes the previous filter frame 4. In this way, the pretreatment of sewage will be more effective and faster. The sewage flows into the iron mesh frame 8, and the smaller debris in the sewage is processed again. The debris enters the iron mesh and is retained. The sewage flows through the first filter plate 10 with a smaller aperture. Similarly, when there are too many debris, the extraction handle 9 is used to remove the iron mesh frame 8. Replacement is carried out to avoid accumulation of debris. The sewage then flows into several funnels 11 respectively. The reduction in the diameter of the flow path slows down the water flow and enters the filter cartridge 13 for more subtle filtration. Similarly, after the filter cartridge 13 has been used for a period of time, the connector 12 is twisted to replace the filter cartridge 13 to ensure efficient work. The filtered sewage comes to the buffer pool 14 for convergence, and then passes through the water pipe 15 to the flocculation furnace 16. Because the microorganisms in the water body are difficult to filter, chemical treatment methods are required. When a certain amount of sewage is present, the flocculant 17 begins to be added, and the second motor 18 is started to drive the blades 20 on the rotating rod 19 to rotate to form an agitator, so that the microorganisms in the sewage and the flocculant 17 fully react to form flocculent solids that precipitate at the lower end of the flocculation furnace 16, and the liquid continues to pass through the second filter plate 21 with a smaller hole diameter and enters the drain pipe 22 for discharge. After a certain period of time, the butterfly valve 24 on the sewage pipe 23 is opened to discharge the flocculent fixed and incompletely discharged liquid into the sewage pool 25 for recycling and filtration again.
