Sewage treatment device

Abstract

The present invention provides a sewage treatment device, which comprises: a housing having a containing cavity, a water injection port, a water discharge port and a sewage discharge port, the sewage discharge port is located at the bottom of the housing, and the water injection port and the water discharge port are located above the housing; the sedimentation assembly is arranged in the containing cavity to divide the containing cavity into a first cavity body and a second cavity body, the sedimentation assembly is provided with a sedimentation plate and a blocking piece, the sedimentation plate is provided with a communicating hole, the communicating hole is used for allowing flocculates to pass through, and the blocking piece has an avoiding state and a blocking state which are oppositely arranged; the blocking piece is arranged away from the communicating hole, and when the blocking piece is in the blocking state, the blocking piece blocks the communicating hole; the separation assembly is rotatably arranged in the first cavity so as to separate the cavity into a plurality of reaction areas, the rotating axis of the separation assembly is parallel to the axis of the shell, and the reaction areas can be communicated with the water injection opening. Through the technical scheme provided by the invention, the problem of low sewage treatment efficiency in the prior art can be solved.
