[0035] With such a design, when in use, sewage is input through the water inlet pipe group 4 in the water collecting tank 1 by an external power device, such as a water pump, and the sewage then passes through the corresponding auxiliary mechanisms in sequence and is finally discharged into the interior of the top water filter tank 2, and then the sewage is filtered by the filler in the water filter tank 2, and the filtered substances in the sewage are decomposed and absorbed by plants, and then the sewage is filtered again by the filler in the water collecting tank 1 and stored in the space below the filter plate 3 in the water collecting tank 1, and the water source obtained after filtration is pumped out through the water outlet pipe group 5 by an external power device, such as a water pump, so as to facilitate subsequent reuse.

[0036] However, after a long period of use, the filler used to filter sewage will become hardened, resulting in a significant decrease in the passing rate of sewage, which will reduce the sewage treatment efficiency. In order to solve this technical problem, the following technical solutions are now provided:

[0037] The auxiliary mechanism includes an outer cylinder 6, a return spring 7, a slide column 8, an inner cylinder 9, a mounting block 10, a plurality of stirring rods 11, a support spring 12, an upper butt joint pipe 13 and a lower butt joint pipe 14, wherein the outer cylinder 6 is fixedly arranged on the filter plate 3, the return spring 7 and the slide column 8 are both movably arranged inside the outer cylinder 6, the return spring 7 is located above the slide column 8, the inner cylinder 9 is rotatably arranged at the center of the slide column 8, the inner cylinder 9 is fixed to the plurality of stirring rods 11 through the mounting block 10 and are both connected, the support spring 12 and the upper butt joint pipe 13 are both movably arranged inside the inner cylinder 9, the support spring 12 is located below the upper butt joint pipe 13, an inner spiral groove 15 is formed at the barrel mouth of the outer cylinder 6, an outer spiral protrusion 16 is formed on the outer side of the inner cylinder 9, the outer spiral protrusion 16 is used in spiral cooperation with the inner spiral groove 15, and a pressure valve 17 is fixedly arranged inside the upper butt joint pipe 13, and the lower butt joint pipe 14 is fixedly arranged at the bottom end of the outer cylinder 6 and the two are connected.

At this time, under the action of the pressure, the sliding column 8 will drive the inner cylinder 9 to move upward and squeeze the return spring 7. Under the cooperation of the inner spiral groove 15 and the outer spiral protrusion 16, the inner cylinder 9 rotates during the upward movement, so that the inner cylinder 9 drives the stirring rod 11 thereon to rotate, so that the compacted filler is broken and stirred by the rotating stirring rod 11, and when the sewage stops being transported, at this time, under the action of the return spring 7, the sliding column 8 will drive the inner cylinder 9 to move downward. At this time, under the cooperation of the inner spiral groove 15 and the outer spiral protrusion 16, the inner cylinder 9 rotates again during the downward movement, so that the inner cylinder 9 drives the stirring rod 11 thereon to rotate again, so that the compacted filler is broken and stirred by the rotating stirring rod 11, making the filler looser and having a good filtering efficiency for the sewage.
