Fixed frames 33 located inside the tank body 1 are fixedly connected to the inner sides of the fixed sleeves 32. Rotating rollers 34 are rotatably connected between the respective shaft discs of a group of fixed frames 33. A filter belt 35 is sleeved on the outer sides of a group of rotating rollers 34. The rear upper shaft disc of the rear fixed frame 33 is fixedly connected with a motor 36. The end of the output shaft of the motor 36 is fixedly connected to the rear end of the upper rotating roller 34. A scraping housing 4 is fixedly connected to the upper side of the tank body 1. An electric telescopic rod 5 is fixedly connected to the rear side hole position of the scraping housing 4. A pushing block 6 is fixedly connected to the front end of the output of the electric telescopic rod 5. An anti-flushing part 7 is installed at the tank body 1. The anti-flushing part 7 includes an air pump 71. The air pump 71 is fixedly connected to the front side of the tank body 1. The upper exhaust end of the air pump 71 is communicated with a ventilation pipe 72. The upper right end of the ventilation pipe 72 is communicated with an exhaust housing 73. Folding rods 74 are fixedly connected to the front and rear sides of the exhaust housing 73. The lower ends of the folding rods 74 are fixedly connected to the upper end surface of the tank body 1. A sewage collection box 8 is arranged on the front side of the tank body 1. A control box 9 is installed on the front side of the tank body 1.

[0027] The lower end surface of the baffle 31 is fixedly connected to the lower inner wall of the tank body 1. The liquid inlet pipe 2 is arranged between the outer end surfaces of a group of baffles 31. The filter belt 35 is arranged between a group of baffles 31. The left inclined surface of the filter belt 35 and the right inclined surface of the baffle 31 are in the same plane. Through this setting, the leachate entering the tank body 1 is restricted by the two-sided baffles 31 and needs to pass through the filtration of the filter belt 35 before entering other areas of the tank body 1; the scraping housing 4 is of an inverted trapezoidal shell structure. The front end and the upper end of the scraping housing 4 are open. Through this setting, the scraping housing 4 can receive the impurities cleaned, and the collected impurities can be discharged from the front end. The sewage collection box 8 is arranged on the lower front side of the scraping housing 4. The front end surface of the scraping housing 4 and the rear end surface of the sewage collection box 8 are in the same plane. Through this setting, the sewage collection box 8 can receive the impurities discharged from the front end of the scraping housing 4; the left end of the scraping housing 4 is in contact with the outer surface of the filter belt 35. Through this setting, the scraping housing 4 can clean the surface of the filter belt 35. The pushing block 6 is of an inverted trapezoidal block structure. The outer end surface of the pushing block 6 is in contact with the inner wall of the scraping housing 4. The pushing block 6 is arranged at the rear side of the filter belt 35. Through this setting, the pushing block 6 cooperates with the electric telescopic rod 5 to push the impurities remaining in the scraping housing 4 forward; the filter belt 35 is an endless annular perforated belt structure. The exhaust housing 73 is arranged inside the filter belt 35. The exhaust housing 73 is arranged above the scraping housing 4. The exhaust holes of the exhaust housing 73 face to the right. Through this setting, the airflow discharged from the exhaust housing 73 can perform an anti-flush on the filter belt 35, eject the stubborn impurities inside the filter belt 35, and collect them through the scraping housing 4.

[0028] Workflow: The treatment operation of the leachate impurities in the leachate collection pool is as follows. The leachate entering the pool body 1 through the liquid inlet pipe 2 is restricted by the baffles 31 on both sides and needs to pass through the filter belt 35 to enter other areas of the pool body 1. The filter belt 35 can filter the passing leachate, and the filtered impurities will adhere to the surface of the filter belt 35. By controlling the control box 9 to rotate the output end of the motor 36 clockwise, the uppermost roller 34 will rotate clockwise accordingly, thereby driving the displacement of the filter belt 35. The displacement of the filter belt 35 enables the scraping shell 4 to scrape the impurities on the surface of the filter belt 35 into the scraping shell 4. At the same time, the air pump 71 started by the control box 9 will convey air flow to the exhaust shell 73 through the air pipe 72, so that the air flow discharged from the exhaust shell 73 can backwash the filter belt 35 and eject the stubborn impurities inside the filter belt 35, which are collected by the scraping shell 4, keeping the filter belt 35 always in a filtering state. On the other hand, every once in a while, the control box 9 will automatically stop the motor 36 and start the electric telescopic rod 5 to extend according to the program setting. The stop of the motor 36 will cause the filter belt 35 to stop moving, and the extension of the electric telescopic rod 5 will push the push block 6 forward to push the impurities remaining in the scraping shell 4 forward into the sewage collection box 8, and then reset, enabling the leachate collection pool to automatically and efficiently treat the leachate impurities entering the pool body 1 and maintain the filtering performance of the filtering mechanism for a long time.
