Bei Förderung des Abwasserschlamms aus dem Faulraum nach den Trockenplätzen mittels Pumpe wird die Trocknung des Schlammes dadurch ungünstig beeinflußt, daß aus ihm die Gase entweichen. Gerade der Gasgehalt des aus einem Zersetzungsbrunnen abgelassenen Schlammes ist aber bekanntlich für die Trocknung auf dem Schlammtrockenplatze sehr wichtig. Gemäß der Erfindung wird derWhen conveying the sewage sludge from the digester to the drying area by means of The drying of the sludge is adversely affected by the fact that from the pump the gases escape from him. Just the gas content of what is drained from a decomposition well But sludge is known to be very important for drying on the sludge drying area. According to the invention, the
ίο gepumpte Schlamm zunächst in einen Behälter gebracht, in welchem er eine Zeit lang verbleibt, bis er sich von neuem mit Gasen angereichert und dabei gleichzeitig einen Teil seines Schlammwassers verloren hat. Erst dann fließt er auf die niedriger liegenden Schlammtrockenplätze. Dies ist in der anliegenden Zeichnung dargestellt. Zwischen dem Zersetzungsraum α und dem Ergänzungsbehälter b ist ein Pumpwerk f eingeschaltet. Durch das Rohr d fließt der Schlamm nach dem Trockenplatze β. ίο pumped sludge first placed in a container, in which it remains for a while until it has been enriched again with gases and at the same time has lost part of its sludge water. Only then does it flow onto the lower lying mud-drying areas. This is shown in the attached drawing. A pumping station f is connected between the decomposition space α and the supplementary tank b . The sludge flows through the pipe d to the drying area β.
Bei der Verbindung des Ergänzungsbehälters mit der Pumpe kommt außerdem noch hinzu, daß der Pumpenschacht und die zu ihm führenden Schlammleitungen meist sehr tief liegen und Grundwasserzuflüsse infolgedessen nicht zu vermeiden sind. Der Schlamm ist infolge des Grundwassers dann wasserhaltiger. Auch dieser Nachteil wird in dem Ergänzungsbehälter wieder beseitigt, weil das zugedrungene Grundwasser im Ergänzungsbehälter Gelegenheit hat, sich wieder abzuscheiden und getrennt abgelassen werden kann.When connecting the supplementary tank to the pump, there is also that the pump shaft and the mud pipes leading to it are usually very deep and groundwater inflows cannot be avoided as a result. The mud is owing of the groundwater then more water-containing. This disadvantage also becomes apparent in the supplementary container Eliminated again because the groundwater that had seeped in was an opportunity in the supplementary tank has to be deposited again and can be drained separately.
