The invention relates to the field of 
environmental protection equipment, particularly to a swing type 
aeration device for domestic 
sewage treatment. The swing type 
aeration device comprises a 
pool body, a fixing frame, a water injection 
pipe and a 
water discharge pipe, wherein the top of the 
pool body is fixedly connected with the fixing frame, the lower surface of the fixing frame is fixedly connected with a mounting frame, a driving shaft is mounted in the fixing frame, a swing rod is hinged to the bottom of the 
pool body, the top of the swing rod is fixedly connected with an 
aeration disc,the side wall of the fixing frame is fixedly connected with an 
air blower, the bottom of the pool body is fixedly connected with a swing motor, a stirring shaft penetrates through the mounting frame,and the lower end of the stirring shaft is fixedly connected with a stirring plate. According to the invention, in an aeration process, the aeration disc swings back and forth so as to uniformly 
discharge bubbles into 
sewage, so that the bubbles and the 
sewage are mixed uniformly; and the aeration plate is driven by the driving motor to rotate, the 
surface layer sewage is lifted by the aeration plate to make the 
surface layer sewage completely contact air so as to carry out aeration on the 
surface layer sewage, and the sewage is stirred by the stirring rod so as to completely mix the sewage and the bubbles.
