The development and application prospect of activated sludge mathematical model

Activated sludge series mathematical models have gone through a development process from static to dynamic models, from imperfect to perfect, it has become an effective tool to guide the operation, parameter adjustment and correction of actual sewage treatment plants. This paper summarizes the development process, advantages and disadvantages of the activated sludge mathematical model, the advantages and limitations of the mathematical model in application. Analyze and discuss the problems that need to be solved in the future development of activated sludge mathematical model, and look forward to the future application trend of activated sludge mathematical model.
