The invention discloses a roller of a pile-turning machine for treating sludge, and the roller comprises a roller body with multiple harrow knife arrays distributed on the surface, wherein each harrow knife array is composed of harrow knives sequentially arranged at intervals. The harrow knife arrays are arranged in inverted-V shapes on an expanded surface of the roller surface. Each harrow knife on two sides of each inverted-V shape is corresponding to a gap between two adjacent harrow knives on the two sides of upper and lower adjacent inverted-V shapes. Each harrow knife is composed of a vertical knife part vertical to the roller surface and a bent knife part formed through upward bending and extending of the vertical knife part. The bent knife parts of the harrow knives on two sides of each inverted-V shape extend towards each other. The roller mounted on the pile-turning machine can turn the sludge smoothly and make a standard pile shape formed, which results in a better fermentation effect. 本发明公开了种处理污泥用
