[0033] The present application is used to treat sewage. First, large particles of impurities in the sewage are crushed by a double-roll crushing mechanism 2. At the same time, the crushed small particles of impurities can flow downward through the sewage funnel 3 to the partition filter assembly 4 along with the sewage. The sewage can continue to flow downward through the partition filter assembly 4, and the crushed particle impurities will remain on the surface of the partition filter assembly 4. The scraping mechanism 5 and the partition filter assembly 4 are scraped to the inside of the crushing circulation channel 6 and the particle separation channel 7. Particles with a size that meets the crushing requirements will fall into the particle separation channel 7 and flow out of the sewage treatment box 1, while particles with a size that does not meet the crushing requirements will enter the crushing circulation channel 6 and be fed to the top of the sewage treatment box 1 through the feeding auger 8 for secondary crushing. The activated carbon layer 9 and the filter cotton layer 10 further filter and adsorb the sewage to clean the impurities in the sewage. Finally, the filtered sewage is discharged from the drain outlet 11.

[0034] The partition filter assembly 4 includes a positioning ring body 41, and a water-permeable filter screen 42, a crushing filter screen 43 and a circulation leak 44 are arranged inside the positioning ring body 41.

The crushing filter screen 43 will leak out the granular impurities that meet the particle size standard and flow through the particle separation channel 7 to the outside of the sewage treatment box 1, while the large granular impurities that do not meet the particle size standard will enter the feeding auger 8 from the circulation leak 44 through the crushing circulation channel 6 for circulation crushing.

[0041] The roller crushing mechanism 2 drives the driving shaft of one of the crushing rollers 21 to rotate through the coordinated output of the second motor 22 and the second reducer 23, and then realizes the counter-rotation of the two crushing rollers 21 through the meshing gear set 24.
