The spiral conveying structure includes a central axis 51, a spiral blade arranged around the central axis 51; 52, and a rotating motor 53 for driving the central axis 51, and the spiral blade; the bottom of 52 is in contact with the surface of the filtrate plate 4; the central axis 51 is controlled to rotate by the rotating motor 53, and then the central axis 51 drives the spiral blade; 52 rotates, and the solid on the filtrate plate 4 is continuously transported upward, and the liquid in the solid garbage falls through the filtrate plate 4. A sewage pipe can be connected to the bottom of the filtrate plate 4 to transport the falling liquid. At the same time, in the process of transporting solid garbage by the spiral blade; 52, the liquid attached to the fixed garbage also flows downward continuously, and finally passes through the filtrate plate 4 and is output, realizing the transportation and separation of solid garbage and liquid; the solid garbage transported to the top is rotated by the push plate 3, and is continuously pushed to the top of the conversion drum 2, and falls from the top of the conversion drum 2 into the conversion drum 2, and then undergoes biological transformation inside the conversion drum 2.
