The municipal sewage treatment device according to claim 7, wherein the outer wall of the aeration chamber (7) is fixed with a first motor (22) through screws, the output shaft of the first motor (22) is connected with a rotating rod (23) through a coupling, sleeves (24) are respectively clamped on the inner walls of both sides of the aeration chamber (7), a sealing sleeve is clamped on the inner wall of each sleeve (24), a rotating circular plate (28) is rotatably connected to the inner wall of each sealing sleeve, the sleeves (24) and the rotating circular plates (28) are both hollow, and the rotating circular plates (28) are clamped on the outer wall of the rotating rod (23).

9. The municipal sewage treatment device according to claim 8, wherein a first air outlet pipe (26) and a second air outlet pipe (27) are respectively fastened to the inner wall of the rotating circular plate (28), an air inlet pipe (21) is respectively fastened to the inner walls of the two sleeves (24), the oxygen pump (20) is fixed to the outer wall of the aeration chamber (7) through screws, the air outlet of the oxygen pump (20) is connected to the two air inlet pipes (21) through a three-way valve, and a second water pipe (8) is fastened to the inner wall of the aeration chamber (7).

10. A treatment method for the municipal sewage treatment apparatus according to any one of claims 1 to 9, comprising the steps of:

s1: sewage is discharged into the filtering chamber (1), the filtering chamber (38) is floated by the floating air bag (29) to ensure that the filtering net (37) is always under the water surface, and then the filtering net (37) filters the water;

s2: the two motors II (34) are controlled to respectively drive the cutters (35) on the two sides to rotate, so that massive sludge in sewage is crushed, and water flow generated by rotation of the cutters (35) can prevent the filter screen (37) from being blocked;

s3: when the cutter (35) rotates to drive the filtering bin (38) to move, the filtering bin can impact the corrugated wall surfaces (2) on two sides, the force rebounded by the floating air bag (29) by the corrugated wall surfaces (2) is oblique, so that the filtering bin (38) can be continuously impacted in the filtering chamber (1), residues on the filtering screen (37) are shaken off, and meanwhile, the cutter (35) is shaken to prevent the cutter (35) from being wound by sundries;

s4: the sludge flows into the drying chamber (9) from the water pipe III (10), falls on the dispersion plate (15), compresses the spring (17), enables the dispersion plate (15) to incline, and under the partition of the partition plate II (14), the sludge is dispersed and falls on the conveyor belt I (12);

s5: when the first conveyor belt (12) moves, the first partition plate (13) can extrude the dispersion plate (15) to enable the dispersion plate (15) to incline downwards so that sludge completely falls off, then the heating wire (16) primarily heats the sludge, then the sludge falls on the second conveyor belt (18), and the heating pipe set (19) dries and sterilizes the sludge;

s6: starting the water pump (5), pumping the water filtered by the filter bin (38) to the first water pipe (6), driving the fan (25) to rotate by the water flow of the first water pipe (6), enabling the rotating rod (23) to rotate, driving the rotating circular plate (28) to rotate, then sending oxygen to the sleeve (24) and the rotating circular plate (28) by using the oxygen pump (20), and discharging the oxygen from the first air outlet pipe (26) and the second air outlet pipe (27);

s7: when the surface of water surpassed fan (25), can starting motor (22), drive fan (25) and rotate, stir rivers, and outlet duct one (26) and outlet duct two (27) are the rotating condition, can improve the area of contact of oxygen and rivers, improve reaction efficiency.
