The results of experimental and mathematical modelling of simultaneous carbonization, nitrification and denitriiication processes in an industrial wastewater treatment plant are presented. Simplified dynamic mathematical models based on organic and nitrogen substrates, autotrophic and heterotrophic biomass material balances for complete-mixing and tank-in-series hydraulic regimes and Monod-type kinetics were developed. These models were verified by using experimental data obtained in laboratory tank-in-seres equipment with high internal recirculation flow as well as by application of the real Carriousel plant data. The influence of unsteady-state conditions on selected process kinetic parameters was also studied in this work. The process dynamic behaviour in the lab-scale tank-in-series equipment was modelled by step shock loading of the substrate concentration.
