Environment-friendly sludge treatment equipment for sewage treatment plant

The invention provides environment-friendly sludge treatment equipment for a sewage treatment plant. The environment-friendly sludge treatment equipment for the sewage treatment plant comprises a machine body; the centrifugal structure is arranged in the machine body, and the centrifugal structure comprises a centrifugal roller for centrifugally dewatering sludge and a sealing assembly for sealing one side of the centrifugal roller. According to the environment-friendly sludge treatment equipment for the sewage treatment plant, the sealing assembly is arranged on the outer side of the centrifugal roller and is mainly used for sealing the outer side of the centrifugal roller, meanwhile, the function of automatically cleaning sludge in the centrifugal roller can be achieved, and after sludge dewatering is completed, the telescopic assembly extends, so that the sludge in the centrifugal roller can be recycled. Finally, the cleaning piece can horizontally move outwards in the centrifugal roller, then the sludge f
