Process for the production of biogas by continuous fermentation of substrate mixtures and biogas plants for the continuous fermentation of substrate mixtures

摘要

The present invention describes a process for the fermentation of substrate mixtures which predominantly animal manure, in particular horses contain solid manure. The object is achieved, in which the dry residue in the fermenter is raised far. This has the result that the fermenter at the same dwell time can be designed smaller and the sand does not contained in the animal manure in the fermenter is sedimented. Further solutions for problems are described, which occur especially in biogas plants, the predominantly animal manure, in particular horses manure fermentation. These are, inter alia, the problem of poor degassing of the fermenter contents, as well as the abseparieren of a fine substances -, highly viscous processing water from the sand content fermentation substrate a biogas installation, which predominantly solid manure it, in particular horses will ferment solid manure.
