Process and device for the decontamination of contaminated sites

摘要: A process and device for decontamination of contaminated soil wherein is precleansed by a pressurized flushing cutting jet located in borehole. The removed from the existing structure flushed so intensely that largely freed adhering pollutants. fine particles soil, together with pollutants, are sluiced as slurry return flow through preventer. For decontamination, they conveyed to plant where remaining pollutants extracted. coarse remain ground. Finally, cleansed bonding agent, back into borehole it forms capable bearing loads.
