Centrifugal separation and discharge equipment based on waste water classification treatment

The invention discloses centrifugal separation and discharge equipment based on waste water classification treatment, relates to the technical field of sewage treatment equipment, and solves the problems that most of existing sewage treatment equipment and filter screen assemblies need to be additionally matched with driving motors and cannot be driven by centrifugal motors of the equipment in a linkage manner, so that the cost and power consumption of the equipment are not favorably reduced. The centrifugal separation and discharge equipment based on waste water classification treatment comprises a water pan, a motor is locked and vertically supported in the center of the interior of a water receiving disc, a circular bottom cover is fixed to the top end of a rotating shaft of the motor in a threaded mode, and two semicircular surrounding plates are annularly arranged on the periphery of the water receiving disc in a sleeving mode; the water pan comprises vertical supporting shaft rods, four vertical support
