[0039] Working principle:

[0040] First, a large amount of wastewater is discharged into the filter box 3. After being filtered by the filter screen 7, it is discharged into the wastewater collection box 8. The first water pump 13 is started, and the first water pump 13 draws the wastewater from the wastewater collection box 8 into the odor adsorption box 9.
