[0047] Step 5, after the sewage aeration treatment, through the first connecting port 5 and the second connecting port 6 into the waste discharge structure 3 to process the solid; that is, the sewage enters from the second connecting port 6 of the front side wall of the waste discharge pool body 31 and is located in the mesh roller 36 that fits the inner wall of the waste discharge pool body 31;

[0048] Step 6, by driving the second motor 34 on the second support 32, the transmission belt 288 of the gear box 33 drives the rotation shaft 35 to rotate, since the mesh roller 36 is arranged on the rotation shaft 35 through the roller frame 82, the mesh roller 36 is driven to rotate in the waste discharge pool body 31, and the mesh roller 36 is driven to rotate along with the rotation of the inclined material guide plate 81, the solid is retained between the material guide plate 81 and the inner wall of the mesh roller 36, and the water is discharged through the mesh roller 36;

[0049] Step 7, when the solid is driven to rotate to the uppermost inner wall of the mesh roller 36, the material guide plate 81 is inverted downward, and then the solid falls into the discharge ladder 38 on the support 37, and is slid out for processing through the inclined discharge ladder 38; at the same time, the liquid pump 40 on the gantry 39 is driven, the liquid pump 40 is connected to the water supply according to the demand, and the water is supplied to the backflushing arm 41 and is sprayed out through the plurality of nozzles 92 on the inner wall of the mesh roller 36, so as to prevent the mesh roller 36 from being blocked due to the attachment of the solid on the inner wall;

[0050] Step 8, since the backflushing arm 41 is symmetrically arranged, and the solid can be driven to filter in the forward rotation or the reverse rotation of the mesh hole, therefore, one of the backflushing arms 41 can be used according to the rotation direction of the mesh roller 36.

[0051] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
