PROCESS AND DEVICE FOR SIMULATING WATER QUALITY

WIPO Patent Application WO/2010/055642

A1

Provided is a process for simulating water quality which comprises: an analysis step for analyzing the concentrations of individual compound components of waste water flowing into a biological reaction tank; a COD conversion step for converting the concentrations of the individual components analyzed above into the COD concentrations of the individual components; a parameter setting step for setting stoichiometric parameters and kinetic parameters; a dissolved oxygen concentration-measuring step for measuring the concentration of dissolved oxygen in the biological reaction tank; a calculation step for calculating the COD concentrations of the individual components in the water that has been subjected to the biological aerobic treatment in the biological reaction tank with the use of the COD concentrations of the individual components, the parameters and the dissolved oxygen concentration; and a component concentration-conversion step for converting the COD concentrations of the individual components of the biologically treated water, which has been calculated above, into the concentrations of the individual components.  Also provided is a device therefor.
