摘要

Abstract

A two-dimensional numerical model is developed to simulate the flow

transport and biodegradation of toluene during bioventing (BV) processes in the unsaturated zones.The simulation for a single well BV system is used to illustrate the effect of air injection rate on remediation efficiency.The air is injected into the vadose zone to create a positive pressure.Simulation results show that air injection rate is a primary parameter governing the dispersal

redistribution and surface loss of contaminant.At injection rates of 81.504 m

·d

(Run 1) and 407.52 m

·d

-1

(Run 2)

the total removed mass of toluene is 169.14 kg and 170.59 kg respectively.Ratios of volatilization to bio-degradation in Run 1 and Run 2 are 0.57:1 and 0.89:1

respectively

indicating that lower air injection rate enhances the biodegradation efficiency greatly.Air injection rate should be optimized to meet oxygen demand and to minimize the operational cost.
