One end of the hydraulic cylinder 408 passes through the collecting box 406 and is fixed with a push plate 409. A driving motor 410 is fixed on the surface of one side plate 404. The output shaft of the driving motor 410 passes through the side plate 404 and is fixed with a linkage shaft 411. One end of the linkage shaft 411 is rotatably connected to the surface of the other side plate 404. A driving wheel 412 is fixed on the surface of the linkage shaft 411. A driven wheel 413 is fixed on the surface of the rotating shaft 405. The driving wheel 412 and the driven wheel 413 are connected through a belt drive.

[0026] The electric push rod 402 can drive the top plate 403 to move downward, so that the collection box 406 can be immersed in the sewage. When the moving mechanism 3 drives the linkage plate 401 to move, the scum on the surface of the treatment pool 1 will be collected in the collection box 406, and the sewage will be able to pass through the collection box 406 through the through groove, and the scum will be blocked by the filter 407. After the scum is collected, the electric push rod 402 is reset and the collection box 406 is moved to the top of the collection pool 2 through the moving mechanism 3, and then the drive motor 410 is started to make The linkage shaft 411 drives the driven wheel 413 to rotate through the driving wheel 412, so that the rotating shaft 405 can drive the collection box 406 to rotate downward 90 degrees. At this time, the scum inside the collection box 406 can be separated by itself due to the influence of gravity. When encountering some scum adhering to the inside of the collection box 406, starting the hydraulic cylinder 408 can make the push plate 409 move toward the opening of the collection box 406, so that the scum remaining in the collection box 406 can be pushed away, thereby achieving the effect of automatically cleaning the collection box 406.

[0027] Further, the moving mechanism 3 includes two support frames 301, a first linear module 302 is fixed on the top of the support frame 301, a connecting shell 303 is fixed on the surface slide of the first linear module 302, a second linear module 304 is fixed on the bottom of the connecting shell 303, a connecting frame 305 is fixed on the surface slide of the second linear module 304, and the bottom of the connecting frame 305 is fixedly connected to the top of the linkage plate 401;
