Abstract

Aiming at the problems in wastewater treatment process

such as high energy consumption and penalty

a condition recognition based intelligent optimal control system for wastewater treatment is proposed. In order to ensure the accuracy and real-time performance of condition identification

the adaptive genetic algorithm is used to select reference variables from a variety of influent parameters

then based on the established historical knowledge base

identifies the real-time influent condition. Multi-objective optimization for energy consumption and penalty is guided by historical knowledge

and through the method of intelligent decision-making

the optimal preference solution is selected from

pareto

solution set

then update the knowledge base. The international benchmark simulation platform BSM1 is used to verify the results. The results show that the proposed method effectively utilizes the optimal solution information of historical conditions

improves the convergence of the algorithm

reduces the computational cost

and can control the energy consumption and fines at a lower level.
