Automatic dosing system for controlling fouling organisms of seawater once-through cooling water system

The utility model discloses an automatic dosing system for controlling fouling organisms of a seawater once-through cooling water system, belongs to the technical field of killing treatment of once-through cooling water systems, and solves the technical problems that an existing circulating cooling water system is low in control automation degree and cannot monitor and adjust the dosage of a bactericide in time. The distributed control system is connected with the bactericide detection module and is used for analyzing a bactericide dosage index in the bactericide detection module and outputting a control signal; meanwhile, the decentralized control system is also connected with the bactericide adding module to control the bactericide adding module to add a bactericide into the seawater direct-flow circulating water; the decentralized control system outputs signals after data analysis by inputting the dosage concentration of the bactericide, the size of the seawater once-through cooling water flow meter and th
