Wenn man in dem Schlammbrunnen^(vergl. Grundriß Fig. 3, Querschnitt Fig. 2, Längsschnitt Fig. 1) durch schräge Zwischenwände ein Absitzbecken α einbaut und das Becken von Abwasser durchflossen wird, so rutscht der Schlamm ununterbrochen durch öffnungen 0 in den Brunnen f. Hier fault der Schlamm aus, bildet Gase und lagert sich teils am Boden ab, teils bildet er eine Schwimmdecke. Die Öffnungen 0 sind so gebaut, daß die aufsteigenden Gasblasen oder Schlammfladen nicht wieder in das Absitzbecken zurücktreten können. If a sedimentation basin α is built into the sludge well (see plan Fig. 3, cross section Fig. 2, longitudinal section Fig. 1) through inclined partition walls and the basin is traversed by sewage, the sludge slips continuously through openings 0 into the well f. Here the sludge rots out, forms gases and is partly deposited on the bottom, partly it forms a floating cover. The openings 0 are built in such a way that the rising gas bubbles or sludge cakes cannot recede into the settling basin.

Der Erfolg einer solchen Reinigung ist *5 der, daß das abfließende Wasser völlig frisch bleibt (wie beim Absitzverfahren), der Schlamm aber ausfault (wie beim Faulverfahren).The success of such a cleaning is that the draining water is completely fresh remains (as with the sedimentation process), but the sludge rots out (as with the digestion process).

Das Wesentliche dabei ist, daß die Flüssigkeit in dem Faulraum f in Ruhe bleibt und daß kein gefaultes Wasser aus dem Faulraum in das abfließende Wasser überströmt. Die Absitz- und Faulräume sind durch Zwischenwände voneinander getrennt;The essential thing is that the liquid in the digestion chamber f remains at rest and that no putrid water flows over from the digestion chamber into the draining water. The settling and septic areas are separated from each other by partitions;

haben gleichen Wasserspiegel. Die Zahl ^a5 und Bauart der Räume ist im übrigen beliebig.have the same water level. The number ^a 5 and the type of room is otherwise arbitrary.

Claims

Patent Claims:

1. Process for the mechanical purification of wastewater in which it flows Settling rooms and for the further treatment of the resulting and automatically draining sludge in Lazy rooms, which are separated from the sitting rooms by partition walls, characterized in that in the lazy rooms any movement of water and an entry of gases or water from the septic tanks into the settling rooms if possible is prevented.

2. Device for applying the method according to claim 1, characterized in that that in one or more mud wells made by built-in sloping partition walls sedimentation basins and the sludge outlet openings at the lowest points after the digester are designed in such a way that the vertically rising gas bubbles or silt patties do not enter the settling basin can resign.
