STUDY OF EFFECTIVENESS OF IN-SITU REMEDIATION USING LAUNCHER-TYPED WELL BY LABORATORY EXPERIMENT AND NUMERICAL ANALYSIS

Abstract

 Our laboratory has developed the launcher-typed well as groundwater purification technique method. The semi launcher-typed well composed of two wells was chosen since 2002. In this study, the adsorption-desorption model is established through two laboratory apparatuses and our numerical analysis. Parameters of pollutant mass transfer are identified with laboratory column experiments. Remediation by the semi launcher-typed well is simulated sufficiently in the three-dimensional numerical analysis. The numerical results agree well with the experimental results. Those results are expected to lead to forecasting in utility-scale of purification of contaminated area both in soil and aquifer.
