Abstract: The biogasification plant has two heatable drying fermenters (1) connected with percolate processor (6), which consists two closed chambers connected with one another as heating chamber (7) for percolate from the drying fermenter and as fermentation chamber (8) for methanizing organic acids dissolved in the heated percolate, The percolate arrives from one of the drying fermenter to the percolate processor and/or to other drying fermenter. The organic acid in the fermentation chamber is arranged at a structure body with a large surface for the settlement of methane-forming microorganisms. The biogasification plant has two heatable drying fermenters (1) connected with percolate processor (6), which consists two closed chambers connected with one another as heating chamber (7) for percolate from the drying fermenter and as fermentation chamber (8) for methanizing organic acids dissolved in the heated percolate, The percolate arrives from one of the drying fermenter to the percolate processor and/or to other drying fermenter. The organic acid in the fermentation chamber is arranged at a structure body with a large surface for the settlement of methane-forming microorganisms. The microorganisms accomplish the dismantling of the organic acid in the drying fermenter to fermentation gas. At the fermentation chamber, a gas drainage pipe for fermentation gas developing in the fermentation chamber is present. In or at the fermentation chamber, a biomagnetic oscillation resonance module is arranged in such a way that the oscillation pattern produced by the bio magnetic oscillation resonance module influences on the microorganisms. In or at the fermentation chamber, a resonance body is arranged in such a way that the oscillation fields influence on the microorganisms in the fermentation chamber. In the drying fermenter, a transverse wall is arranged, so that the percolate introduced into the drying fermenter flows through a biomass pile (2). The drying fermenter consists of a base plate, two side panels and a rear wall and circulating- or U-shaped recess comprising two flexible web-shaped bodies, whose end area is inserted into the recess. On the end areas of the flexible body in the recess, air-filled hose is arranged over an air compressor. The percolate processor consists of a base plate, four side panels and a partition wall. The heating chamber and/or the fermentation chamber of the percolate processor is so connected with the drying fermenter that the heated percolate from the heating chamber and/or the putrefied percolate from the fermentation chamber is applied on the biomass pile of the drying fermenter. The heated and/or the putrefied percolate flow through the biomass pile and the organic acids dissolved in the biomass pile are rinsed out. The two flexible bodies are arranged one above the other and the area between the flexible bodies is connected with an air compressor. A mixture from poured organic material and bog iron ore in the drying fermenter for the desulfurization of the fermentation gas is so placed that the developing fermentation gas before withdrawal from the drying fermenter passes to the mixture, where gaseous hydrogen sulfide is precipitated in form of a salt connection. The mixture is present in an area at the rear wall of the drying fermenter and/or on the biomass in the drying fermenter. An independent claim is included for procedure for the biogasification.
