Intelligent control method, system and equipment for adding amount of PAC and storage medium

The invention discloses an intelligent control method, system and device for the PAC dosage and a storage medium. The intelligent control method comprises the steps that the inflow water quality turbidity change value of external inflow water is detected; the PAC dosing concentration of the mixed sedimentation tank is determined according to the inflow water quality turbidity change value; calculating the PAC dosage concentration of the PAC solution box according to the PAC dosage concentration; the water inlet flow of a water inlet pipeline, the rated output of a dosing metering pump and the stroke opening of the dosing metering pump are obtained; calculating the frequency of a dosing metering pump according to the PAC dosing concentration, the PAC dosage concentration, the water inlet flow, the rated output of the dosing metering pump and the stroke opening; and controlling the dosing metering pump to work based on the dosing metering pump frequency. When the inlet water quality of the mixed sedimentation t
