Accurate water distribution system equipment for secondary sedimentation tank

The utility model relates to accurate water distribution system equipment for a secondary sedimentation tank, relates to the technical field of sedimentation tanks, and aims to solve the problem that uneven water distribution is easy to occur when a water distribution tank distributes water to a plurality of sedimentation tanks. The accurate water distribution system equipment comprises a water distribution tank and a plurality of sedimentation tank bodies, and a water distribution device communicated with one sedimentation tank body is arranged on the water distribution tank; an intercommunication mechanism is arranged between every two adjacent sedimentation tank bodies, each intercommunication mechanism comprises an intercommunication branch pipe and an opening and closing assembly used for controlling connection and disconnection of the interior of the intercommunication branch pipe, and the two ends of each intercommunication branch pipe are communicated with the adjacent sedimentation tank bodies respec
