METHOD FOR BUILDING PREDICTIVE MODEL OF MICROORGANISM-DERIVED DISSOLVED ORGANIC NITROGEN IN WASTEWATER

摘要

A method for building a predictive model of mDON in wastewater, including a) acquiring a kinetics associated with production and consumption of a mDON of an activated sludge system, and importing a kinetic expression of the mDON into a conventional activated sludge model No. 1 (ASM1) to build a kinetic equation for the mDON; b) inputting component variables, parameter variables, model matrices, process rate equation and operating parameters of a predictive model into a simulation software AquaSim to build an ASM-mDON model; c) inputting initial values of the component variables and the parameter variables into the simulation software AquaSim for model initialization; d) acquiring initial mDON kinetic and sensitivity analysis results, selecting corresponding parameters, calibrating kinetic and stoichiometric parameters of the ASM-mDON model using a parameter estimation function of the simulation software AquaSim; and e) replacing the initial values of the ASM-mDON model with optimal values obtained in d).
