MULTI-FUNCTIONAL WELL SUITABLE FOR IN-SITU INTEGRATED TREATMENT OF SOIL AND GROUND WATER

摘要

PURPOSE: A multifunctional tube well for an integrated process of processing the subsurface water and soil underground is provided to increase the efficiency of a soil cleaning process on the soil layer of the pollution area. CONSTITUTION: A multifunctional tube well for an integrated process of processing the subsurface water and soil underground comprises a tube well casing and a horizontal pipe for injecting a surface active agent(400). The tube well casing comprises a connection pipe(100) for an aquifer, a connection pipe(200) for an unsaturated layer and an LNAPL extraction column(300). The horizontal pipe for injecting a surface active agent is extended vertically to the tube well casing. The horizontal pipe for injecting a surface active agent is located the unsaturated layer or a sand layer formed on the top of the unsaturated layer.
