The aerated mixing mechanism for sewage treatment as claimed in claim 6, wherein: The transmission member (206) comprises a driving motor (206a), a transmission rod (206b), a transmission block (206c) and a fixed block (206d), the driving motor (206a) is fixed to the inner wall of the driving box (204), the transmission block (206c) is fixed to the outer side of the transmission rod (206b), and the fixed block (206d) is fixed to one side of the connecting plate (205).

8. The aerated mixing mechanism for sewage treatment as claimed in claim 7, wherein: The transmission block (206c) is in the shape of a semicircular cake, is arranged in multiple groups and is different in angle; the transmission block (206c) in the shape of a semicircular cake rotates as a whole with the transmission rod (206b), when the circular cake end rotates to the fixed block (206d), the transmission block (206c) strikes the fixed block (206d) to flip the connecting plate (205) and strike the filter plate (202); when the circular defect end rotates to the fixed block (206d), the transmission block (206c) cannot contact the fixed block (206d), and the connecting plate (205) is reset under the action of the buffer member (207).

9. The aerodynamic mixing mechanism for sewage treatment as claimed in claim 6 wherein: The buffer member (207) comprises a connecting block (207a) and a spring (207b), the connecting block (207a) is fixed to the inner wall of the driving box (204), and the spring (207b) is fixed between the connecting block (207a) and the connecting plate (205).

10. The aerated mixing mechanism for sewage treatment as claimed in claim 9, wherein: The connecting block (207a) and the transmission block (206c) are arranged on different horizontal planes.
