The invention discloses a highly-efficient 
aeration device for 
sewage purification treatment, and relates to the technical field of 
forestry machinery. The highly-efficient 
aeration device comprises an 
aeration box and a 
settling box connected with the aeration box, wherein a rotating frame is fixedly arranged on a rotating sleeve 
pipe in a sleeving mode; a hollow shaft extending into the aerationbox is rotatably arranged in the rotating sleeve 
pipe; and an air delivery 
pipe I extending into the hollow shaft is arranged at the outlet end of an 
air pump I. According to the invention, through arrangement of the 
air pump I and an 
air pump II, external air can respectively enter the aeration box through spray heads and an air spray disc; through arrangement of a stirring mechanism, 
sewage andair in the aeration box can realize aeration under the action of stirring, so the content of 
oxygen in water is greatly improved, and full oxidation and 
decomposition of microorganisms to organic matters are promoted; through arrangement of a reversing mechanism, the stirring mechanism can be driven to alternately rotate forwards and backwards, so the stirring efficiency is significantly improved; and through arrangement of stirring plates which can rotate around rotating shafts and can rotate around the rotating sleeve pipe at the same time, sufficient mixing of 
oxygen and 
sewage is greatlypromoted, and the aeration effect is significantly improved.
