Intelligent coagulant adding method for waterworks under switching of multiple water sources

The invention relates to the technical field of water treatment and environmental engineering, in particular to a waterworks intelligent coagulant adding method under switching of multiple water sources, which comprises the following steps: inputting first type sequence data corresponding to a current time period of a waterworks into a pre-trained sedimentation tank coagulant adding amount prediction model, obtaining a predicted value of the coagulant addition amount at a first time interval after the current time of the specified sedimentation tank; the first type of sequence data comprises a reuse water flow sequence QR, a coagulant amount sequence AR consumed by reuse water, a flow sequence QC entering a specified sedimentation tank, and a coagulant sequence and a water source flow sequence respectively corresponding to each water source of the waterworks; if the waterworks meet preset adding conditions within a first time interval after the current time, a first adding instruction is sent to a coagulant a
