Then, the first motor 23 drives the connecting frame 26 to reciprocate, so that the impurities are scraped off by the first scraper 27 and the second scraper 28 and scraped into the collection box 212 for collection and centralized treatment, and it will not affect the use of the first filter plate 21. And the medicine is mixed by the stirring blades 37 to make it fully fused, and then the medicine is transported into the sewage treatment tank 1 through the water pump 32 to react with the sewage, so as to treat the sewage. There are two second scrapers 28, and the two second scrapers 28 are symmetrically and fixedly connected inside the connecting frame 26. By the two second scrapers 28, the contact area is increased, so that the impurities move closer to the position of the first scraper 27.

[0026] Please refer to Figures 1 - 4 , in this embodiment, the first filter plate 21 is fixedly connected inside the sewage treatment tank 1. The baffle 22 is fixedly connected inside the sewage treatment tank 1. The first motor 23 is fixedly connected to the front of the sewage treatment tank 1. The output end of the first motor 23 is fixedly connected with a threaded rod 24. The threaded rod 24 is rotatably connected inside the sewage treatment tank 1. The external thread of the threaded rod 24 is connected with a slider 25. The slider 25 is slidably connected inside the sewage treatment tank 1. The connecting frame 26 is fixedly connected to the right side of the slider 25. The positioning rod 29 is fixedly connected to the front of the sewage treatment tank 1. The mounting shell 210 is slidably connected to the outside of the positioning rod 29. The bolt 211 is threadedly connected inside the mounting shell 210. The collection box 212 is fixedly connected to the top of the mounting shell 210. The handle 213 is fixedly connected to the front of the collection box 212. The second filter plate 214 is fixedly connected inside the collection box 212. The first motor 23 makes the connecting frame 26 reciprocate. While cleaning the first filter plate 21, it will not affect the use of the first filter plate 21 and ensure the use performance of the first filter plate 21. A chute is opened at the corresponding position of the sewage treatment tank 1 for the slider 25, and the slider 25 slides inside the chute. The chute limits and guides the slider 25 to prevent the slider 25 from shifting. The first filter plate 21 is in contact with the baffle 22. The first scraper 27 and the second scraper 28 contact the first filter plate 21, which is convenient for the first scraper 27 and the second scraper 28 to effectively clean the surface of the first filter plate 21 and completely scrape off the impurities on it.

[0027] Please refer to Figure 1 、Figure 5 In this embodiment, the mixing mechanism includes a mixing tank 31. The sewage treatment tank 1 is fixedly connected to the right side of the sewage treatment tank 1. A water pump 32 is fixedly connected to the left side of the sewage treatment tank 1. The top of the water pump 32 is fixedly connected to a second pipeline 34. The second pipeline 34 is fixedly connected to the inside of the sewage treatment tank 1. A first pipeline 33 is fixedly connected between the water pump 32 and the mixing tank 31. The bottom of the mixing tank 31 is fixedly connected to a second motor 35. The output end of the second motor 35 is fixedly connected to a rotating shaft 36. The rotating shaft 36 is rotatably connected to the inside of the mixing tank 31. The outer part of the rotating shaft 36 is fixedly connected with stirring blades 37. The second motor 35 drives the stirring blades 37 to stir the liquid medicine, making the mixing of the liquid medicine more sufficient, so as to react better with the sewage. There are two stirring blades 37, and the two stirring blades 37 are symmetrically and fixedly connected to the outer part of the rotating shaft 36. The two stirring blades 37 increase the contact area with the liquid medicine, thus making the mixing efficiency higher.

[0028] When working, the injected sewage is filtered through the first filter plate 21. The baffle 22 prevents the sewage from entering the inside of the sewage treatment tank 1 through the blank area. The impurities are filtered and stay on the surface of the first filter plate 21. The first motor 23 drives the threaded rod 24 to rotate. The rotation of the threaded rod 24 drives the slider 25 to move. The slider 25 drives the connecting frame 26. The connecting frame 26 scrapes the surface of the first filter plate 21 through the first scraper 27 and the second scraper 28. Due to the inclined surface design of the first scraper 27 and the second scraper 28, when the connecting frame 26 moves backward, the impurities can be pushed to the center position. Then the first motor 23 drives the threaded rod 24 to rotate in the reverse direction. The connecting frame 26 moves forward. The first scraper 27 pushes the impurities in the center position, and then they fall into the inside of the collection box 212. The second filter plate 214 can filter the sewage inside the collection box 212 and discharge it into the inside of the sewage treatment tank 1. When the bolt 211 does not contact the positioning rod 29, the collection box 212 can be driven through the handle 213. The collection box 212 drives the mounting shell 210 to slide off from the outside of the positioning rod 29, and the impurities inside the collection box 212 are processed. The medicine and water are placed inside the mixing tank 31. The second motor 35 drives the rotating shaft 36. The rotating shaft 36 drives the stirring blades 37. The stirring blades 37 rotate to stir the medicine and water. The water pump 32 pumps out the mixed liquid medicine through the first pipeline 33 and transports it to the inside of the sewage treatment tank 1 through the second pipeline 34, so as to react with the sewage. The treated sewage can be discharged through the drain port 4.

[0029] Through the above steps, the first scraper and the second scraper reciprocate to clean the surface of the first filter plate, thereby scraping and concentrating the impurities filtered on the surface of the first filter plate for treatment, so as to solve the problem that if the impurities stay on the surface of the filter plate and are not cleaned in time, the filter plate will be blocked.
