Method and apparatus for cleaning polluted environmentally degraded land, especially method and apparatus for reducing radioactive exposure to environmentally degraded land due to radioactive contamination

摘要

The present invention releases a particularly radioactive and degraded environment for purifying polluted and degraded environments, including contaminated biomass, particularly biogas facilities 5 where fermentation of plant contaminated biomass is fermented It relates to processes and equipment for reducing the radiation load. In at least one fermentation tank of biogas facility 5, biogas 7, contaminated liquid, or fermentation residue 8 in the form of a humid body are generated. The fermentation residue 8 is supplied to at least one drying device 9, which is dried therein to form a contaminated dry fermentation residue 10 having a predetermined residual water content. The dried fermentation residue 10 is preferably supplied to the incineration or gasification apparatus 11 together with a predetermined amount of wood. The contaminated ash 15 generated in the incineration or gasification apparatus 11 is discharged and separated, and is specifically sent to the permanent treatment location 16.
