Sewage hardness prediction method and device, electronic equipment and storage medium

The invention discloses a sewage hardness prediction method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring an ion concentration parameter causing hardness increase in sewage and a sewage pH value; according to the ion concentration parameter and the pH value of the sewage, determining the types of chemicals for reducing the hardness of the sewage and the dosage of each type; and predicting whether the hardness of the treated sewage is qualified or not by using a pre-trained error inverse feedback neural network prediction model by taking the ion concentration parameter, the medicament type and/or the dosage of each type as input. An artificial intelligence algorithm model is introduced into sewage hardness treatment, so that sewage hardness prediction and treatment automation and continuous self-learning optimization are realized, the hardness of treated sewage is accurately predicted, the medicament feeding feedback is more timely, and the medicamen
