Coagulant distribution box for efficient sedimentation tank

The utility model relates to the technical field of sewage treatment, in particular to a coagulant distribution box for an efficient sedimentation tank, which is characterized in that a controller is mounted at one end of a box body, a guide plate is fixed on one side edge of the upper side of the box body, and three uniform sprinkling mechanisms with the same structure are arranged on the outer side of the guide plate; and the uniform material spraying mechanism comprises a sliding shell arranged on the outer side of the guide plate in a sliding and sleeving mode, a position adjusting mechanism is arranged between the sliding shell and the guide plate, and a fixing plate is fixed to the upper side of the sliding shell. According to the utility model, the spray pipe is driven to rotate through the rotary driving mechanism, so that the spray head is driven to rotate, the sprayed coagulant can be uniformly distributed in the sedimentation tank, the mixing efficiency of the coagulant is improved, the sewage trea
