The invention discloses an accurate control device for a flow field of a biological pool. The accurate control device is arranged in a biological pool and comprises a submersible stirrer, an axial flow velocity regulator, a guide rod, a speed sensor and a control system, wherein the control system is arranged on the biological pool, the guide rod is vertically arranged in the biological pool, the submersible stirrer is arranged on the guide rod, a variable-frequency control panel is arranged on one side of the submersible mixer, the axial flow velocity regulator and the speed sensor are arranged in the biological pool, the axial flow velocity regulator is vertically arranged right in front of the submersible mixer, and the speed sensor and the variable-frequency control panel are connected with the control system. The invention further designs an accurate control method for the flow field of the biological pool. According to the method, the flow field of the biological pool is accurately controlled, the flow speed at a plane of the biological pool is dynamically and accurately controlled, a plane stirring range is expanded, and a stirring dead zone is reduced, so activated sludge at different positions of the biological pool is well in a suspended state, and the phenomenon of sludge precipitation is avoided.
