摘      要：This paper analyses the oxidation of ferrous iron via chemical and biological means in a class of Sequential Batch Reactors(SBR-type).For this,a kinetic model for the study of iron oxidation system is proposed,followed by a parametric sensitivity analysis and a bifurcation analysis,which allow selecting the most influential kinetic parameters in order to ensure a suitable prediction capacity of the mathematical *** system consists of two SBR bioreactors,the first being used to produce hydrogen peroxide(H2O2)that is fed to a second reactor where the iron oxidation is carried out by chemical–biological *** predictions were compared with experimental data for the production of H2O2 and for ferrous iron oxidation,finding suitable correlation coefficients(r2 N 0.98)for each state *** bifurcation analysis showed the trajectories of the main variables,such as,biomass,H2O2 and ferrous iron,under the change of the most influential kinetic *** analysis demonstrates the usefulness of the constructed model to predict the kinetic behaviour of the SBR-type process.
