The invention provides a peripheral-in peripheral-out secondary sedimentation tank water distribution system, which is characterized in that a lifting device is additionally arranged at the terminal of a peripheral-in peripheral-out secondary sedimentation tank water distribution channel, and the lifting device is used for lifting mud-water mixed liquid at the terminal of the water distribution channel and conveying the mud-water mixed liquid to the initial end of the water distribution channel, so that hydraulic circulation is formed in the water distribution channel. According to the peripheral-in peripheral-out secondary sedimentation tank water distribution system, water at the tail end of the water distribution channel is transported to the starting end through the lifting device, hydraulic circulation is formed in the water distribution channel, the water flow speed at the tail section of the water distribution channel is always larger than the silt flow speed, the silt problem existing at the tail end
