ABSTRACT:
Reactor for anaerobic prefermentation of aqueous waste waters provided with a waste water inlet, an outlet for discharging prefermented waste water and a sludge outlet. The interior of the reactor comprises one first reactor space and one second reactor space, while a precipitation cone is suspended by ribs between the first and second space. A covering sheet extends from the wall of the reactor into the precipitation cone, said covering sheet being provided with a gas escaping tube which ends above the upper edge of precipitation cone.
The reactor is further provided with a storage vessel for supplying basic substances to the second reactor space. The outlet debouches into an annular precipitation space having an annular partition; the precipitation space is further bounded by an annular overflow with tooth-shaped recesses.
At last a protein removing line and a liquid drain-cock are present.
