Numerical Simulation of Benzene in Soil Contaminant Transport by Finite Difference Method

Abstract:

In this paper, the two-dimensional saturated soil adsorption and desorption of contaminant transport model was considered, and it is discreted by the Crank-Nicolson difference scheme method. The benzene contaminant in the original organic chemical cesspool was determined, and the transportation of benzene contaminant is simulated by Matlab software. Simulation results show that the benzene concentration in the sewage pool reduced to 1.15mg/kg, where can be used for various soil types by the migration effect of the soil after a decade. This established model and simulation methods can be used for estimating other existing benzene contaminated soil pollution.
