The invention discloses a control device and control method for air blowers of a sewage treatment system, and relates to the technical field of sewage treatment system air blower control, wherein the control device comprises a plurality of air blowers, an air blower controller, a plurality of branch pipelines, a plurality of air inlet regulating valves, a plurality of online dissolved oxygen instruments and a main controller; the output ends of the plurality of air blowers are connected with a main pipeline through output pipelines, and the main pipeline is provided with a pressure transmitter; the air blower controller is electrically connected with the plurality of air blowers; one ends of the branch pipelines are connected with the main pipeline, and the other ends of the plurality of branch pipelines are respectively connected with a plurality of aeration tanks; the plurality of air inlet regulating valves are respectively arranged on the plurality of branch pipelines; the plurality of online dissolved oxygen instruments are respectively arranged in the plurality of aeration tanks; and the main controller is electrically connected with the pressure transmitter, the air blower controller, the plurality of air inlet regulating valves and the plurality of online dissolved oxygen instruments, and the main controller is used for controlling the operation of the plurality of air blowers through the air blower controller according to the opening degrees of the plurality of air inlet regulating valves and the dissolved oxygen concentration measured by the plurality of online dissolved oxygen instruments.
Description
technical field [0001] The invention belongs to the technical field of blower control in a sewage treatment system, and more specifically relates to a control device and a control method for a blower in a sewage treatment system. Background technique [0002] With the continuous improvement of the effluent water quality requirements of sewage treatment plants, the upgrading of water plants is imminent. For the biological nitrogen and phosphorus removal process, the control of dissolved oxygen affects the quality of its nitrogen and phosphorus removal effects. The control of dissolved oxygen is mainly obtained through the precise aeration system, which needs to be operated in conjunction with the blower system to achieve stable control of dissolved oxygen in the biological pool. The blower main control system (MCP) receives two kinds of signals, one is pressure signal and the other is gas flow signal. How to transmit the accurate control signal to the main control system of ...
