A front mixing part, a rear mixing part and a filtering part are sequentially arranged in the tank body 1 along the flow direction of the sewage. Under the action of the front mixing part and the rear mixing part, the sewage and the flocculant are stirred multiple times, so that the flocculant can be fully mixed with the sewage, so that the impurities in the sewage can be stably agglomerated, and under the action of the filtering part, the agglomerated solid impurities can be stably filtered, so that the impurity agglomerates are separated from the water by filtering, thereby reducing the impurity content in the sewage discharged from the tank body 1.
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the rear mixing part is formed with a mixing chamber 2, and the mixing chamber 2 is connected with an upper liquid inlet 3 and a lower liquid outlet 4, and the lower liquid outlet 4 is covered with an elastic deformation plate 5, and a liquid outlet slit 6 is surrounded between the elastic deformation plate 5 and the lower liquid outlet 4, and the elastic deformation plate 5 is set as a rubber sheet, and the good elastic deformation performance of rubber is used to ensure that the elastic deformation plate 5 has good and stable elastic deformation performance, so that the sewage and flocculant can push the elastic deformation plate 5 to elastically deform, so that the opening degree of the liquid outlet slit 6 is larger, ensuring that the sewage and the flocculant can stably flow out of the mixing chamber 2 The mixing chamber 2 provided can form a relatively independent chamber, so that the sewage and flocculant entering the mixing chamber 2 can be better mixed by the rear mixing part, so that the contact between the sewage and the flocculant is more sufficient, and the upper liquid inlet 3 and the lower liquid inlet are provided so that the mixed liquid of the sewage and the flocculant can fully flow through the mixing chamber 2, and at the same time, under the blocking effect of the elastic deformation plate 5, the time for the mixed liquid of the sewage and the flocculant to flow out of the mixing chamber 2 can be slowed down, so that the rear mixing part can better mix the sewage and the flocculant, so that the flocculant has a more sufficient treatment effect on the sewage.
[0025] like Figure 2 As shown, a first guide plate 7 is fixedly connected to the tank body 1, a first guide groove 8 is arranged between the first guide plate 7 and the inner bottom surface of the tank body 1, and a stirring chamber 9 for a front mixing part to penetrate is arranged between the first guide plate 7 and the tank body 1. The sewage and the flocculant are firstly introduced into the stirring chamber 9, and the sewage and the flocculant in the stirring chamber 9 are mixed by the front mixing part. At the same time, under the action of the first guide plate 7 and the first guide groove 8, the sewage and the flocculant will pass over the first guide plate 7 along the first guide groove 8, so that the sewage and the flocculant stay in the tank body 1 for a longer time, thereby ensuring a better flocculation effect of the overall structure.
[0026] like Figure 2-Figure 5 As shown, the top of the pool body 1 is fixedly connected to a connecting piece 10 by bolt locking. The connecting piece 10 is generally in the shape of a long strip with an open top. The front mixing portion includes a first rotating rod 11 rotatably connected to the connecting piece 10 and a plurality of first stirring blades 12 fixedly connected to the bottom of the first rotating rod 11. The plurality of first stirring blades 12 are fixed to the first rotating rod 11 along the circumferential direction respectively by welding. The top of the first rotating rod 11 is fixedly connected to a first driving motor 13 fixedly connected to the connecting piece 10. The first driving motor 13 is configured as a servo motor and is fixed to the connecting piece 10 by bolt locking. The first driving motor 13 rotates to drive the first rotating rod 11 to rotate. The rotation of the first rotating rod 11 drives the plurality of first stirring blades 12 to rotate, thereby achieving stirring and mixing of sewage and flocculant.
[0027] like Figure 2-Figure 5 As shown, a partition plate 14 is fixedly connected in the tank body 1, and the partition plate 14 divides the tank body 1 into a front chamber 15 and a rear chamber 16 that are independent of each other.

The elastic deformation plate 5 and the second baffle 20 are fixed to each other. This arrangement ensures that the sewage and flocculant first enter the mixing tube 18 from the upper liquid inlet 3 and flow along the mixing tube 18 to the lower liquid outlet 4 to flow out, so that the sewage and flocculant can fully flow through the mixing chamber 2, ensuring that the rear mixing part can stably achieve mixing of the sewage and the flocculant.
[0028] like Figure 2-Figure 5As shown, the rear mixing part also includes a second rotating rod 21 rotatably connected to the connecting piece 10, and the top of the second rotating rod 21 is fixedly connected to a second driving motor 22 fixedly connected to the connecting piece 10, and the second driving motor 22 is configured as a servo motor. Two groups of second stirring blades 23 distributed up and down are fixedly connected to the second rotating rod 21, and the second stirring blades 23 in the same group are circumferentially distributed along the central axis of the second rotating rod 21. The rotation of the second driving motor 22 drives the second rotating rod 21 to rotate, and the rotation of the second rotating rod 21 drives the second stirring blades 23 to rotate. The rotation of the second stirring blades 23 realizes sufficient stirring and mixing of the sewage and the flocculant, and the two groups of second stirring blades 23 are configured as a structure distributed up and down. This configuration ensures that the second stirring blades 23 are more evenly distributed in the height direction of the mixing tube 18. When the sewage and the flocculant flow into and out of the mixing tube 18, they will be stirred multiple times by the two groups of second stirring blades 23, ensuring that the sewage and the flocculant are more fully mixed.

The third driving motor 30 is arranged as a servo motor. The rotation of the third driving motor 30 will drive the third rotating rod 28 to rotate. The rotation of the third rotating rod 28 will drive the scraper plates 29 to rotate. The scraper plates 29 rotate to bring the impurities in the ash collecting trough 26 into the ash outlet trough 27. The ash outlet trough 27 is connected to a pump body, and the impurities in the ash collecting trough 26 are extracted under the action of the pump body.
[0030] like Figure 1 , Figure 2 and Figure 5As shown, a filter tank 31 is surrounded by the second guide plate 24 near the liquid outlet side and the tank body 1, and the filter part includes a connecting frame 32 fixed to the filter tank 31, and a plurality of inclined plates 33 in an array are fixedly connected in the connecting frame 32 by welding, and an inclined slot 34 is surrounded by two adjacent inclined plates 33. With the help of the provided connecting frame 32, the inclined plates 33 are stably supported and limited. In the process of the upward flow of the sewage and flocculant mixed liquid, the clumped impurities will stably fall and accumulate in the ash collecting tank 26 under the shielding of the inclined plates 33 and the action of gravity on themselves. A partition plate 35 is fixedly connected to the tank wall of the filter tank 31 above the connecting frame 32, and two rows of liquid discharge holes 36 distributed in an array are opened on the partition plate 35. A liquid discharge slot 37 is opened on the tank body 1 above the partition plate 35, and further buffering of the sewage is achieved under the action of separation.
