1, the wastewater treatment apparatus 100 includes a housing 110, a vortex generating unit 200 and a mesh filter 150 inside the housing 110. The housing 110 has a cylindrical shape and is hollow inside. The upper and lower surfaces of the housing 110 are opened. The vortex generating unit 200 and the mesh filter 150 are disposed in the longitudinal direction of the housing 110.

The upper side of the housing 110 is formed with a wastewater inlet 120 passing through in the vertical direction and a lower side is formed with a sludge outlet 140 passing through in the vertical direction and a treated water outlet 130 passing through in the outer direction . Therefore, the wastewater treatment apparatus 100 separates the sludge and the purified water from the inside of the housing 110 through the wastewater inlet 120 on the upper side, and the treated water after the purification process is discharged to the outside of the housing 110 And the separated sludge is drained through the sludge outlet 140 formed on the lower side of the housing 110. [

At this time, the sludge outlet 140 may be connected to a separate sludge drain device.

The sewage inlet 120, the treated water outlet 130 and the sludge outlet 140 are generally formed into a circular shape in section and can be detachably attached to the housing 110 in a prefabricated manner according to the purpose and use of the invention, And may be integrally formed with the housing 110. That is, the sewage inlet 120, the treated water outlet 130, and the sludge outlet 140 can be bolted to the housing 110 in various sizes in consideration of the inflow amount for treating the wastewater and the size of the sludge.

The vortex generating unit 200 and the mesh filter 150 are assembled and arranged in the housing 110. The vortex generating unit 200 is disposed in the longitudinal direction of the housing 110 and has a cylindrical mesh filter 150 spaced to surround the vortex generating unit 200. That is, the mesh filter 150 serves as a filtering network capable of hanging the sludge of the wastewater through a wire mesh, and is formed in a cylindrical shape having a predetermined radius so as not to be in contact with the vortex generator 200 but spaced apart by a certain distance. Specifically, the mesh filter 150 is preferably cylindrical in shape such that the upper and lower surfaces thereof are opened like the housing 110.

The mesh filter 150 may be coupled to an inner upper portion of the housing 110 and may be coupled to an inner lower portion of the housing 110. In addition, the mesh filter 150 may be installed so as to be longitudinally connected from the upper portion of the inner side of the housing 110 to the lower portion thereof.
