Development and applications of enzymatic kinetic models for upgrading the design and operation of biological nutrient removal processes
EF 2009-10
Résumé
The proposed research is to modify the existing enzymatic kinetic equations or develop new enzymatic kinetic equations for describing various process reactions in an activated sludge process especially for nutrient removal from different types of wastewaters. These newly developed equations will be used to modify the existing ASM and BioWin matrix models, with the objectives to improve the design and operation of biological nutrient removal processes, and to protect aquatic environment and public health by reducing negative environmental impacts attributed to excessive discharge of nutrients into aquatic ecosystems.
The model development or modification will be based on the analysis and derivation of enzymatic reactions, the traditional Michaelis-Menten kinetics and the Monod model. A new parameter that is the ratio of effective enzyme to biomass will be introduced into new or modified enzymatic kinetic equations, which will be the innovative part of the research. The new equations will be validated experimentally by conducting three-phase biochemical experiments in an aerated bioreactor on different types of test solutions. The concentrations of the substrate(s) and chemical oxygen demand (COD) will be measured at different reaction times. The kinetic curves of enzymatic reactions will be plotted and kinetic coefficients will be determined from the kinetic curves. The ratio of effective enzyme to biomass will be interpreted by non-linear regression. The validated modified equations will then be used to modify the kinetic equations in the ASM or BioWin matrix models, and newly developed equations will be added into the ASM or BioWin matrix models. The modified ASM and BioWin models are expected to be more accurate, reliable, operable, and user-friendly when used for retrofit or new design of biological nutrient removal processes. The modified ASM and BioWin models will be used to improve the design and operation of biological nutrient removal processes by improving treatment efficiency and reducing the treatment cost and equipment footprint required.
