Fermenter for generating biogas from pumpable organic material

摘要

The invention relates to a fermenter for generating biogas from pumpable organic material with a low content of organic dry matter (oTS), comprising at least one inlet for the pumpable organic material, at least one fixed bed reactor for the pumpable organic material with at least one primary and one secondary section and at least one outlet the remaining fermentation residue. Furthermore, the fermenter can optionally comprises at least one sedimentation chamber for the pumpable organic material, arranged between the primary and secondary sections and at least one recycling section connected to the sedimentation chamber and designed such that specific lighter fractions of the pumpable organic material can be recovered and reintroduced to the rising (primary) section of the fixed bed reactor or a preceding or subsequent conventional fermenter.
