description The invention discloses a sludge aerobic fermentation device, which relates to the technical field of sludge treatment and comprises a stirring tank. The stirring tank comprises a shell and a stirring cavity located in the shell, the stirring cavity comprises an upper cavity body and a lower cavity body which are relatively independent, and the upper cavity body and the lower cavity body are separated by a filter layer; a spiral conveyor is arranged at the bottom of the upper cavity body, is arranged along the bottom of the upper cavity body, and penetrates through the shell to be communicated with the conveying pipe; and a stirring device is arranged in the upper cavity body. In the operation process, sludge is stirred and fermented in the upper cavity body, standing is carried out after sufficient fermentation, components such as humic acid permeate through the filtering layer along with water and enter the lower cavity body, and residual dry materials can be discharged through the spiral conveyor.
