As shown in Figures 1 to 4, the sewage filtration treatment pool of this embodiment includes a sedimentation tank 1. One end of the sedimentation tank 1 is connected to a filter tank 3 through a filter channel 2. A water inlet 4 is provided at the rear end of the filter tank 3. External sewage enters the filter tank 3 through the water inlet 4 for preliminary filtration, and then enters the sedimentation tank 1 for sedimentation after passing through the filter channel 2. A plurality of floating plates 8 are arranged inside the filter tank 3. The floating plates 8 float on the surface of the sewage. A rotating structure 9 is installed at the lower end of the floating plates 8. After passing through the water flow, the rotating structure 9 rotates under the impact of the water flow and draws the surrounding water flow to form a vortex within a certain range. A connecting shaft 11 is installed at the center position of the lower end of the rotating structure 9. A mounting base 13 is installed at the lower end of the connecting shaft 11, and the mounting base 13 and the rotating structure 9 are connected together through the connecting shaft 11. A debris collecting bucket 12 is arranged outside the connecting shaft 11, and the upper end of the debris collecting bucket 12 is an open mouth. The debris pulled by the vortex will enter the interior of the debris collecting bucket 12 and be stored. The lower end of the debris collecting bucket 12 is connected to the edge position of the upper end of the mounting base 13. A plurality of water outlet holes 14 are opened on the lower surface of the debris collecting bucket 12. The sewage entering the interior of the debris collecting bucket 12 will be discharged through the water outlet holes 14. A one-way filter membrane is installed inside the water outlet hole 14. The one-way filter membrane can prevent sewage from entering the interior of the debris collecting bucket 12 through the water outlet hole 14.

Specifically, a grille 5 is installed inside the filter channel 2. Two filter nets 6 are installed at a position of the grille 5 close to the side of the sedimentation tank 1 and inside the filter channel 2. By arranging the grille 5 inside the filter channel 2, the flow rate of the sewage inside the filter channel 2 can be adjusted through the grille 5, and some impurities inside the sewage can be filtered and blocked through the two filter nets 6.

Furthermore, the rotating structure 9 includes a rotating shaft 901 and a rotating plate 902. The lower end of the floating plate 8 is rotatably connected to the rotating shaft 901. A plurality of inclined rotating plates 902 are installed in an array on the side surface of the rotating shaft 901. The inclined rotating plates 902 will drive the rotating shaft 901 to rotate under the impact of the water flow. The plurality of rotating plates 902 and the rotating shaft 901 rotate synchronously, which will drive the water flow to form a vortex of a certain range near the rotating structure 9.

Furthermore, a ring 10 is installed at the upper end of the floating board 8, and a horizontal iron chain 7 is installed inside the filter pool 3. The iron chain 7 passes through multiple rings 10. By passing the iron chain 7 through multiple rings 10, multiple floating boards 8 are connected together, so that the position of the floating board 8 can be limited to prevent the floating board 8 from being washed away by the water flow.

Furthermore, a first mounting groove 15 that is clamped with the bottom end of the connecting shaft 11 is provided at the center position of the upper end of the mounting base 13, and a second mounting groove 16 that is clamped with the debris collection bucket 12 is provided at the edge position of the upper end of the mounting base 13. The second mounting groove 16 is an annular groove. The connecting shaft 11 is clamped with the first mounting groove 15, and the debris collection bucket 12 is clamped with the second mounting groove 16. When the internal space of the debris collection bucket 12 is filled, the mounting base 13 can be removed and the debris collection bucket 12 can be removed to facilitate the discharge of debris.

Furthermore, the mounting base 13 and the debris collection bucket 12 are both in the shape of a funnel that is wide at the top and narrow at the bottom. The size of the floating plate 8 is larger than that of the mounting base 13 and the debris collection bucket 12. The buoyancy of the floating plate 8 drives the lower structure to float on the water surface. The funnel-shaped mounting base 13 and the debris collection bucket 12 are more likely to rotate under the impact of the water flow.

The method of use of this embodiment is as follows: by installing a filter tank 3 at one end of the sedimentation tank 1, and installing a plurality of floating plates 8 inside the filter tank 3, a rotating structure 9 and a debris collection bucket 12 are rotatably connected below the floating plates 8, when sewage flows into the filter tank 3, the rotating structure will rotate under the impact of the water flow to form a vortex, and through the gravitational force of the vortex, the debris passing near the floating plates 8 will be collected into the debris collection bucket 12, and the floating debris will be stored in the debris collection bucket 12 under the action of gravity, and most of the debris on the surface of the sewage can be collected by using a plurality of floating plates 8 and a plurality of debris collection buckets 12, thereby preventing the debris from clogging the subsequent filter screen 6.

Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
