To meet effluent quality (EQ) standard and reduce energy consumption (EC) of wastewater treatment process (WWTP)
a multi-objective optimal control method was developed based on multi-objective particle swarm optimization (MOPSO). First
EC and EQ models from adaptive regressive kernel functions were established by analysis of operation data. Then
MOPSO was designed to optimize EC and EQ models and to reach optimal set-points of dissolved oxygen (SO) and nitrate (SNO) simultaneously. Finally
PID controller was used to trace the optimal set-points of SO and SNO so as to achieve multi-objective optimal control of WWTP. The experimental results from Benchmark Simulation Model 1 (BSM1) for wastewater treatment demonstrated that the proposed multi-objective optimal control method could assuredly meet effluent quality standard as well as effectively reduce energy consumption.
