<p>Reactor (1) for anaerobic prefermentation of aqueous waste waters provided with a waste water inlet (2), an outlet (9) for discharging prefermented waste water and a sludge outlet (6). The interior of the reactor (1) comprises one first reactor space (7) and one second reactor space (8), while a precipitation cone (11) is suspended by ribs (10) between the first (7) and second (8) space. A covering sheet (30) extends from the wall (31) of the reactor into the precipitation cone (11), said covering sheet (30) being provided with a gas escaping tube (39) which ends above the upper edge (13) of precipitation cone (11). …<??>The reactor is further provided with a storage vessel (25) for supplying basic substances to the second reactor space (8). The outlet (9) debouches into an annular precipitation space (17) having an annular partition (19); the precipitation space (17) is further bounded by an annular overflow (14) with tooth-shaped recesses (18). …<??>At last a protein removing line (33) and a liquid drain-cock (20) are present.</p> |
