Method and apparatus for purifying environmentally degraded land due to pollution, in particular, method and apparatus for reducing radiation exposure of environmentally degraded areas due to radioactive contamination

摘要

The present invention includes a biogas facility 5 in which fermentation of contaminated biomass, particularly radioactively contaminated plant biomass, is carried out, particularly for the purification of contaminated and devastated environments. The present invention relates to a process and equipment for reducing the radiation load in a devastated environment. In at least one fermenter of the biogas facility 5, a biogas 7 and a fermentation residue 8 in the form of a contaminated liquid and / or a wet body are produced. This fermentation residue 8 is fed to at least one drying device 9 where it is dried to form a contaminated dry fermentation residue 10 having a predetermined residual water content. The dry fermentation residue 10 is preferably supplied to the incineration and / or gasifier 11 together with a predetermined amount of wood. Contaminated ash 15 generated in the incineration and / or gasifier 11 is discharged, separated, and sent to a permanent processing site 16 in particular.
