Abstract

A method and a device for continuous anaerobic degradation of organic waste are disclosed. The waste is emptied into a hopper (1), which preferably contains rotary rollers (2) equipped with knives for disintegrating the waste. At the bottom of the hopper (1), there is provided an infeed means (5) feeding the waste through a conduit (6) to the downwardly-directed narrow end (7) of a funnel-shaped container (8) exhibiting an acute angle alpha of about 60-160 DEG . During the hydrolysis, the waste is fed upwards through the container (8) while being moistened by liquid injection through nozzles (13) arranged above the container (8) or nozzles (14) arranged inside the container (8). After the treatment, the waste is discharged from the container (8) by outfeed means (9), which preferably comprise two screw conveyors arranged at the upper, opposing edges of the funnel-shaped container. The liquid not absorbed by the waste is drawn off, e.g. through perforations (15), and collected in a tank (16), to subsequently be conducted to a filter (19) where biogas is separated (at 20). After an optional addition of fresh water (at 26), the liquid is recycled to the nozzles (13, 14) and supplied to the waste. When having undergone the inventive treatment and been discharged from the inventive device, the waste may undergo further treatment, such as a maturing stage.
