Water quality energy consumption prediction and optimization control method and system in sewage treatment process

The invention discloses a water quality energy consumption prediction and optimization control method and system in a sewage treatment process, and the method mainly comprises the following steps: collecting sewage data, selecting a specific intrinsic mode function for filtering processing through VMD filtering, and removing interference signals in a specific frequency range; a Reformer model and an STGCN model are established to be used for predicting the effluent quality and energy consumption in the sewage treatment process respectively, optimal parameters are obtained through a water circulation algorithm, and the prediction capacity of the models is improved. And a multi-target water circulation algorithm is established, and optimization control is carried out by taking effluent quality and energy consumption as targets. Compared with the prior art, the method has the advantages that the Reformer model and the STGCN model are used for prediction, the advantages of the two prediction models are combined,
