Estimation of Heterotrophic Biokinetic Parameters in Wastewater Biofilms from Oxygen Concentration Profiles by Microelectrode

Abstract Knowledge of the biokinetic parameters of heterotrophic biofilm is important for reliable modeling and optimization of biofilm wastewater treatment systems. In this article, an approach to quantify heterotrophic biokinetic parameters, including the maximum specific oxygen uptake rate (\documentclass{aastex}\usepackage{amsbsy}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{bm}\usepackage{mathrsfs}\usepackage{pifont}\usepackage{stmaryrd}\usepackage{textcomp}\usepackage{portland, xspace}\usepackage{amsmath, amsxtra}\pagestyle{empty}\DeclareMathSizes{10}{9}{7}{6}\begin{document} $$\stackrel{\smallfrown}{q}_{\max}$$ \end{document}), the Monod half saturation coefficient of oxygen (ko), and the maintenance decay coefficient for oxygen (Km) in wastewater biofilms, was presented and evaluated. With the oxygen microprofiles measured in the biofilm by using the oxygen microelectrode, the heterotrophic biokinetic parameters were determined through fitting the data to the diffusion-reaction models.
