Description

technical field [0001] Based on the operating characteristics of the sewage treatment process of the membrane bioreactor, the invention designs a multi-indicator identification method for membrane pollution by using the cascaded neural network based on the hierarchical learning algorithm, and realizes the multi-index identification method related to the membrane pollution in the sewage treatment process of the membrane bioreactor. The prediction of each index; the multiple indexes related to membrane fouling refer to membrane water permeability, membrane pore radius and membrane life in the process of membrane bioreactor sewage treatment. These indexes are to measure whether membrane fouling occurs, the severity of membrane fouling and Significant signs of features. The multi-index identification method of membrane fouling based on cascaded neural network can improve the accuracy of the multi-index identification model, obtain accurate prediction results, and comprehensively c...
