Self-adaptive prediction method and system for residual chlorine in effluent of waterworks

The invention discloses a self-adaptive prediction method for residual chlorine in effluent of a waterworks, which comprises the following steps: acquiring the residual chlorine in the effluent of the waterworks and historical data of related influence factors, and preprocessing; calculating a lag time interval between each influence factor and the effluent residual chlorine, and performing time dimension data reconstruction on all the influence factors based on a calculation result to generate a historical data set; establishing a prediction model, and training the prediction model by using the reconstructed historical data set to obtain an effluent residual chlorine prediction model; predicting the effluent residual chlorine by using the trained effluent residual chlorine prediction model; the invention further discloses a self-adaptive prediction system for residual chlorine in the effluent of the waterworks. According to the method, the lag time interval between the effluent residual chlorine and the rela
