Abstract
Abstract The invention relates to a process for the anaerobic fermentation of waste water, wherein a sludge, that has been obtained by coagulating and separating difficultly settlable, colloidal and dissolved organic materials of waste water - particularly of waste water of abattoirs - by means of addition of known coagulating agents is fermented.
