Abstract
An arrangement for treating a gas from a contaminated ground region in situ has a shaft wall which is at least partially gas-permeable and forms a shaft in a gas-tightly closed ground region. The shaft wall has a gas-impermeable shaft portion spaced from a shaft opening and two gas-permeable wall portions which surround the gas-impermeable wall portion. Gas transporting means produces a gas circulating flow in the shaft and in the ground region. At least one device for influences the intensity of the gas flow in the shaft in dependence on the density of the ground region for producing and maintaining a laminar gas flow in the ground region. At least one element provided in the region of the gas-permeable wall operates for changing a composition of the gas flow.
