Numerical Simulation Analysis of the Effect of Microbiological Degradation on Organic Contaminant Distribution in Groundwater
Considering convection, dispersion and adsorption-desorption, the kinetic model of the transportation and transformation of organic contaminant, electrical accepter and bacteria in the groundwater system was established by using double Monod microbiological degradation based on the principle of mass conservation. Taking benzene and dissolved oxygen for example, the numerical simulation analysis of contaminant and bacteria in the groundwater system was performed, and the result shows that the bacteria concentration accumulates in the zone which the concentrations of contaminant and dissolved oxygen are both relatively higher; the concentrations of bacteria in aqueous phase and soil phase increase first and then reduce along the main direction of contaminant transportation; the maximum value of bacteria concentration appears in the upstream zone near the pollution source.
