4. An anaerobic pond for sewage treatment according to claim 3, characterized in that the two ends of the moving member (8) contacting with the two partition plates (4) are respectively fixed with a slide block (15);
two sliding grooves (14) are formed in the side wall of each partition plate (4), and each sliding groove (14) is arranged in the horizontal direction;
the four sliding blocks (15) are respectively arranged in the corresponding sliding grooves (14) in a sliding manner.
5. An anaerobic pond for sewage treatment according to claim 4, characterized in that the moving member (8) is near one end of the central tube (5), and the end surface is curved; one end of the moving piece (8) far away from the central tube (5) is wedge-shaped, and the upper surface of the end is an inclined plane.
6. An anaerobic tank for sewage treatment according to claim 5, characterized in that the side of the rotating frame (16) close to the central pipe (5) is inner side, the other side is outer side, the rotating frame (16) is shaped like a Chinese character 'ji' viewed from the inside to the outside;
the outer side wall of the rotating frame (16) is a curved surface, and the curved surface of the rotating frame (16) can be attached to the curved surface of the moving piece (8).
7. The anaerobic tank for sewage treatment as claimed in claim 6, further comprising two sewage pipes (18), wherein the two sewage pipes (18) are both communicated with the anaerobic tank body (1), and the inlet of each sewage pipe (18) is positioned on the bottom wall of the anaerobic tank body (1);
the two moving parts (8) are positioned between the inlets of the two sewage pipes (18);
the water inlet of the drain pipe (17) is positioned at the central position of the bottom wall of the anaerobic tank body (1).
