[0033] In use, wastewater first enters the wastewater sedimentation tank 1, and preliminary sedimentation is performed in the wastewater sedimentation tank 1, and part of large-particle impurities are deposited at the bottom of the tank. The wastewater enters the separation barrel 4 through the connecting pipe 401, and the outlet end of the connecting pipe 401 is below the filter mechanism 6, so the wastewater is first in the lower area of the filter mechanism 6.
