Abstract

Abstract

To handle the complicated influent， petrochemical wastewater treatment facilities are usually designed as a long process including multiple treatment stages. The traditional operation strategy of such plants mainly relies on the experiences of the operators. It usually takes considerable of time and cost to find the optimum operating conditions， and carries unpredictable risks of non-compliance. The use of mechanistic models for simulating the biological processes has been widely applied in optimizing municipal wastewater treatment plants. It’s more challenging to calibrate the mechanistic models for applications in industrial wastewater treatment. This project used BioWin， a process modeling software， to develop and calibrate a model for simulating biological processes， including anaerobic digestion， pure oxygen aeration systems， surface aeration process， and membrane reactors， at a petrochemical wastewater treatment plant in Tianjin. The calibrated model was used to conduct scenarios analyses， systematically optimizing the wastewater treatment facilities to reduce the operational cost and operator workload.
