THINKING ON CONSTRUCTING AN INTELLIGENT CONTROL SCHEME OF WASTEWATER TREATMENT BASED ON THE COMBINATION OF MECHANISM AND DATA-DRIVEN MODELS

Intelligent control of wastewater treatment is the leading edge in the water pollution control field.The rapid development of artificial intelligence technology injects fresh vitality into the development of wastewater treatment intelligent control.It is strongly desirable to explore a scientific route of combining mechanism and data-driven models to reconstruct the logical mode of wastewater treatment intelligent control system and hence promote its technical development level.This paper proposed a tentative plan of dual-loop logical structure based on the certainty-randomness features of wastewater treatment processes,which is likely to provide a new technical route of wastewater treatment intelligent control through future practice and exploration.First,this paper reviewed the essential factors of wastewater treatment intelligent control and dissected the control role of the mechanism model in the certainty scale,as well as the role of the data-driven model in the randomness scale.Then,a dual-loop logical structure and its control principle combining mechanism and data-driven models were proposed,and the topology in the application of complex wastewater treatment processes was clarified.Finally,a brief perspective centering on the future development of wastewater treatment intelligent control technologies was presented.
