Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung bezweckt eine rechtzeitige Ableitung des Klärfrischwassers, welches den Frischwasserschlamm aus dem Klärraum nach dem Faulraum transportiert, ah der unmittelbaren Eintrittsstelle in den Faulraum.The present invention aims at a timely discharge of the fresh sewage water, which transports the fresh water sludge from the clarification room to the digester, ah the immediate entry point into the septic tank.

Bei den bisher zur Ausführung gelangten Kläranlagen' mit Schlammtransport durch Frischwasserströmung nach dem Faulraum ίο vermischt sich das Frischwasser mit dem Faulwasser. Um hierbei den nötigen Abfluß aus dem Faulraum zu schaffen, muß das wegfließende Faulwasser gut filtriert werden, bevor es dem geklärten Frischwasser hinter der Kläranlage wieder zugeführt werden kann. Diese Filtration verursacht umfangreiche Vorkehrungen und Unkosten.In the sewage treatment plants that have been carried out so far with sludge transport Fresh water flow after the digester ίο mixes the fresh water with the Putrid water. In order to create the necessary drainage from the septic tank, the flowing away must Digestion water must be well filtered before it can be fed back into the clarified fresh water behind the sewage treatment plant. This filtration creates extensive precautions and costs.

Bei der vorliegenden Erfindung ist eineIn the present invention, one is

Vermischung des schlammtransportierenden Frischwassers mit dem Faulraumwasser in nur sehr geringem Maße oder gar nicht möglich, so daß dasselbe zur Einleitung in das geklärte Frischwasser hinter der Kläranlage nur eine geringe Reinigung mit wenig Unkosten erfordert. Mixing of the sludge-transporting fresh water with the septic tank water in just very little or not possible at all, so that the same is an introduction to the clarified Fresh water behind the sewage treatment plant requires little cleaning with little expense.

Fig. ι stellt den Schnitt A-B und Fig. 2 den Grundriß der Erfindung dar.Fig. Ι shows the section AB and Fig. 2 shows the outline of the invention.

In bekannter Weise wird der sich in der Düse α ablagernde Frischwasserschlamm durch Absenkung des Faulraum Wasserspiegels von der Frischwasserströmung nach dem Faulraum transportiert.In a known manner, the fresh water sludge deposited in the nozzle α is transported by the fresh water flow to the digester by lowering the septic tank water level.

Erfindungsgemäß erfolgt- der Abfluß des Frischwassers, welches den Schlamm aus der Düse α nach dem Faulraum transportiert, auf kürzestem Wege durch die mit der Schlammventildüse verbundene Haube c und das Rohr d, ohne daß sich hierbei das Frischwasser wesentlich mit dem Faulraumwasser mischen kann, während gleichzeitig der transportierte Frischwasserschlamm ungehindert in den Faulraum b fällt.According to the invention, the fresh water, which transports the sludge from the nozzle α to the digester, is drained by the shortest route through the hood c connected to the sludge valve nozzle and the pipe d, without the fresh water being able to mix significantly with the digester water while at the same time the transported fresh water sludge falls unhindered into the digestion chamber b.
