Study on Modelling and Neural Network Control Algorithm in Sewage Treatment Process

摘要

With the development of industries, the problem of environmental pollution caused by the massive discharge of sewage is becoming more and more serious, which has gained increasing attention of people. In order to solve the problem of drastic change of water quality and dissolved oxygen concentration in wastewater discharge, activated sludge method was used to deal with the discharge of wastewater and the neural network control algorithm was used to model and control the wastewater treatment process in this study. Besides, the neural network predictive control algorithm was proposed to control the concentration of nitrate nitrogen. Through the simulation of the sewage treatment process, it is found that the method can quickly and accurately achieve the desired requirements of the nitrate nitrogen and realize the effective sewage treatment.
