The slag collection and discharge tank 14 is provided with a slag discharge port 18. The spiral shaft 15 is used to rotate and convey the solid garbage to the slag discharge port 18 for discharge. During operation, the sewage is conveyed to the inner cylinder 12. By rotating the inner cylinder 12, at this time, the gripper 13 rotates with the inner cylinder 12. During the rotation of the inner cylinder 12, small-volume garbage and sewage pass through the first filter holes 16 and flow through the outer cylinder 11 and then flow into the sewage treatment tank 1 for treatment. However, the large-volume solid garbage in the sewage is lifted under the interception of the gripper 13 on the inner cylinder 12. When the gripper 13 rotates above the slag collection and discharge tank 14, the solid garbage falls into the slag collection and discharge tank 14. By rotating the spiral shaft 15, the solid garbage is rotated and conveyed to the slag discharge port 18 for discharge, effectively removing the large-volume solid garbage in the sewage in advance and preventing blockage in subsequent treatment processes. The slag collection and discharge tank 14 is open at the top, which is beneficial for collecting the fallen garbage. The structure is simple and easy to use.
