<p>The invention relates to a method for injecting oxygen-containing gases, in particular air, into contaminated, granular or lumpy material, for example in refuse landfills, the oxygen-containing gas being abruptly blown (shot) into the contaminated material intermittently, in particular at a frequency of 1/30 to 1/10 Hz, under a high pressure, for example in the range between 2 and 10 bar, the duration of a blowing-in step preferably being in the range of milliseconds, and to a device for carrying out this method. <IMAGE></p> |
