Operation and management of Liaoning waste water treatment plants by STOAT Simulation

Abstract

Due to the irregular management, the effluent water of some waste water treatment plants (WWPT) of Liaoning province didn’t meet the demand of the National Discharge Standard. Meanwhile, excessive of dosage and discharge of sludge made the results of operation costs increasing and environmental pollution during the processes. The use of mathematical models for the simulationof wastewater treatment processes has gained widespread acceptance as a tool to aid the design of newworks and the optimization of existing facilities. STOAT developed by the Water Research Center is the most widely used model for simulating the WWST processes. This paper invited the STOAT as simulation model for the design and optimization of Liaoning waste water treatment plant.
