摘要

Vertical circulation flow systems induced by groundwater circulation wells are anestablished in-situ groundwater pollution remediation technique. For a effectiveremediation of a groundwater pollution with a groundwater circulation well it wasnecessary to unterstand the influence of a circulation flow field on the mass transferprocess. Therefore one-dimensional soil column experiments and two-dimensional tankexperiments with a circulation flow field have been carried out to systematicallyinvestigate the mass transfer process between the residual NAPL and the aqueousphase. A dissolution model to describe the mass transfer process has been developed.This model assumes that the each residual NAPL phase has a spherical shape and ishomogeneously distributed in the porous medium. With this model it was possible todetermine the mass removed during the experiments and to estimate from experimentaldata the initial NAPL mass in the contamination source.
