<p>1. An apparatus for anaerobic sewage purification having a preferably cubic reaction tank, which comprises a sludge-digestion chamber, a gas collecting chamber and an overflow chamber ; wherein a plurality of partitions, which are disposed horizontally side by side and which are each inclined alternately in relation to the vertical, project from above into the reaction tank, over the whole internal cross-section, wherein the positions overlap one another with their free downwardly directed ends, leaving a gap, and defining channel-shaped gas collecting chambers in the upper region and have passages, each provided with gas-deflecting devices, in their middle region ; characterized in that the partitions (8, 9) extend only for the height of the overflow chamber (6), and the sludge-digestion chamber (5) has at least three times the height of the overflow chamber, that the partitions are connected to one another in pairs to form components (10) in the form of a ridged roof and define the gas-collecting channels (7) at their ridge region, and that pipes (25), which project into the sludge-digestion chamber and into the overflow chamber and which extend substantially horizontally, extend through the partitions and are bevelled upwards in a direction towards the partitions receiving them, at the ends which project into the sludge-digestion chamber.</p> |
