Bioreactor for aerobic or anaerobic hydrolysis in two-stage fermentation of solid wastes

摘要

This unit conducts aerobic or anaerobic hydrolysis in a two-stage solid fermentation of biogenic wastes. It includes an inlet and outlet for the circulating fluid. In this novel arrangement there is a screening drum within the outer casing. This is rotated by a drive. Above the screening drum and connected to the input, there is a sprinkling system. A gas offtake is provided. The lower section of the casing is constructed in the form of a sedimentation trough.
