During the rotation of the solid impurities with the centrifugal mesh cylinder 3, they enter the stationary impurity collection box 4 and are concentrated and attached to the mesh surface of the arc-shaped filter screen 44, which is convenient for collecting the solid impurities in the collection cylinder. After the sewage separation is completed, the movable cover plate 21 is removed, the impurity collection box 4 is taken out, the cleaned impurity collection box 4 is inserted back inside the solid-liquid separation body 1, and then the sewage separation and treatment work is continued.

The centrifugal drum 3 is driven to rotate centrifugally by the rotation of the rotating base 33. The rotating base 33 is driven by a centrifugal motor 32 to rotate the rotating shaft 31, thereby driving the rotation of the rotating base 33. The connecting base 13 facilitates the support of the rotating centrifugal drum 3, enabling the centrifugal drum 3 to rotate stably inside the solid-liquid separation body 1.
