The centrifugal sewage purification and separation device is characterized in that the water inlet 1 is arranged along the tangential direction of the casing 9 . It makes the speed direction of the sewage enter the device from the water inlet just along the tangential direction of the casing 9, and better promote the rotation of the impeller 2, so that the water flow changes from a straight flow to a swirling flow.
