Abstract

Abstract: A microscopic diffusion-reaction model was developed to simulate in-situ ozonation for the
remediation of contaminated soil, i.e., to predict the temporal and spatial distribution of
target contaminant in the subsurface.The sequential strategy was employed to obtain the
numerical solution of the model using finite difference method. A non-uniform grid of
discretization points was employed to increase the accuracy of the numerical solution by
means of coordinate transformation. One-dimensional column tests were conducted to verify
the model. The column was packed with simulated soils that were spiked with 2-chlorophenol.
Ozone gas passed through the column at a flow time intervals. Compared the experimental
data with the simulated values, it was found that the mathematical model fitted data well
during most time of the experiment.

Key words: ozonation, in-situ soil remediation, modeling, 2-chlorophenol
