Abstract

The plant has a sewage manhole (1) for receiving a barrier material collector (2) and a liquid collector (3) that is formed as a partial component on a bottom side of the sewage manhole. The manhole is filled with prefiltered sewage up to a given maximum fluid level (S) by defining the liquid collector. A pump (4) is fully or partly arranged in a pump sump of the sewage manhole, where the pump is designed as a submerged or a centrifugal pump. The sewage manhole is implemented as an existing and/or prefabricated cavity with bricked walls and/or walls made of plastic or steel.

Description

Beschreibung:Description:

Die Erfindung betrifft eine Abwasserhebeanlage, mit wenigstens einem Sperrstoff-Sammelbehälter, einem Flüssigkeits-Sammelbehälter sowie einem Abwasserschacht zur Aufnahme der vorgenannten Anlagenteile. - Der Abwasserschacht dient folglich zur Bevorratung bzw. Einhausung von wenigstens dem Sperrstoff Sammelbehälter sowie dem Flüssigkeits-Sammelbehälter.The invention relates to a wastewater lifting plant, with at least one bulk substance collecting container, a liquid collecting container and a sewage shaft for receiving the abovementioned plant components. - The sewer manhole thus serves for the storage or enclosure of at least the bulk material collecting container and the liquid collecting container.

Solche Abwasserhebeanlagen sind grundsätzlich bekannt und werden beispielhaft in der EP 0 846 810 A2 , der EP 1 108 822 B1 oder auch der FR 752 942 beschrieben. Der Vorteil bzw. das Kernstück der bekannten Abwasserhebeanlagen ist in dem wenigstens einen Sperrstoff-Sammelbehälter zu sehen. Denn der Sperrstoff-Sammeibehälter ist mit zumindest einem in seinem Innern angeordneten Trennsieb ausgerüstet.Such sewage lifting plants are basically known and are exemplified in the EP 0 846 810 A2 , of the EP 1 108 822 B1 or even the FR 752 942 described. The advantage or the core of the known wastewater lifting systems can be seen in the at least one bulk material collecting container. Because the bulk material Sammeibehälter is equipped with at least one arranged in its interior separating wire.

Durch das Trennsieb wird mit Sperrstoffen belastetes Abwasser geführt. Folglich teilt das Trennsieb den Sperrstoff-Sammeibehälter in einen sperrstoffbelasteten Behälterbereich und einen sperrstofffreien Behälterbereich. Lediglich der sperrstofffreie Behälterbereich ist mit der Pumpe und folglich dem Fiüssigkeits-Sammelbehälter verbunden. In dem Flüssigkeits-Sammelbehälter wird demzufolge vorgereinigtes Abwasser bevorratet.Through the separating sieve wastewater contaminated with bulking agents is guided. Thus, the dividing screen divides the barrier collection container into a barrier loaded container section and a non-barrier container section. Only the non-barrier container area is connected to the pump and thus the liquid receiver. Accordingly, prepurified wastewater is stored in the liquid collecting tank.

Um nun das Abwasser mit Hilfe der Abwasserhebeanlage auf ein bestimmtes (höheres) Niveau zu heben, ist die Pumpe regelmäßig mit einer Druckleitung verbunden, die ihrerseits im Allgemeinen an den sperrstoffbelasteten Behälterbereich des Sperrstoff-Sammelbehälters angeschlossen ist. Dadurch wird die Pumpe lediglich zur Förderung von vorgereinigtem Abwasser eingesetzt, so dass einerseits relativ kleine Pumpen verwendet werden können und andererseits die Lebensdauer solcher Pumpen deutlich höher ist im Vergleich zu Abwasserhebeanlagen, die ohne einen solchen Sperrstoff-Sammeibehälter arbeiten. Das hat sich grundsätzlich bewährt.In order to raise the wastewater to a certain (higher) level by means of the sewage lifting system, the pump is regularly connected to a pressure line, which in turn is generally connected to the barrier-contaminated container area of the bulk material collecting container. Thus, the pump is used only for the promotion of pre-treated wastewater, so that on the one hand relatively small pumps can be used and on the other hand, the life of such pumps is significantly higher compared to Wastewater lifting plants that operate without such a bulk waste collection tank. This has proven itself in principle.

Die bekannten Anlagen entsprechend beispielsweise der EP 1 108 822 B1 greifen auf einen vorgefertigten Flüssigkeits-Sammelbehälter zurück, der üblicherweise aus Kunststoff oder auch aus Stahl gefertigt ist. Der Flüssigkeits-Sammelbehälter wird zusammen mit dem Sperrstoff-Sammelbehälter und der wenigstens einen Pumpe in dem Abwasserschacht vor Ort eingebaut. Hieraus resultieren nicht unerhebliche Investitionskosten. Hier will die Erfindung insgesamt Abhilfe schaffen.The known systems according to, for example, the EP 1 108 822 B1 rely on a prefabricated fluid reservoir, which is usually made of plastic or steel. The liquid collecting tank is installed in the sewer manhole together with the bulk material collecting tank and the at least one pump. This results in not inconsiderable investment costs. Here, the invention aims to provide a total remedy.

Der Erfindung liegt das technische Problem zugrunde, eine derartige Abwasserhebeanlage so weiterzuentwickeln, dass insbesondere die Investitionskosten deutlich verringert sind.The invention is based on the technical problem of further developing such a wastewater lifting plant such that, in particular, the investment costs are significantly reduced.

Zu Lösung dieser technischen Problemstellung ist eine gattungsgemäße Abwasserhebeanlage im Rahmen der Erfindung dadurch gekennzeichnet, dass der Flüssigkeits-Sammelbehälter in dem Abwasserschacht als dessen teilweiser Bestandteil ausgebildet ist.To solve this technical problem, a generic wastewater lifting plant is characterized in the invention in that the liquid collecting container is formed in the sewer manhole as its partial component.

im Rahmen der Erfindung übernimmt der Abwasserschacht also gleichsam eine zweifache Funktion. Zunächst einmal fungiert er nach wie vor und unverändert als Hohlraum bzw. Aufnahmekammer für den Sperrstoff-Sammelbehälter und beispielsweise eine dem Sperrstoff-Sammelbehälter zugeordnete Pumpe. Darüber hinaus findet der Flüssigkeits-Sammelbehälter in dem Abwasserschacht Platz. Da jedoch der Flüssigkeits-Sammelbehälter integraler und teilweiser Bestandteil des Abwasserschachtes ist bzw. als ein solcher erfindungsgemäß ausgeführt wird, übernimmt der Abwasserschacht erfindungsgemäß (wenigstens teilweise) zugleich die Funktion des Flüssigkeits-Sammelbehälters.in the context of the invention, the sewer manhole thus assumes a dual function. First of all, it acts as before and unchanged as a cavity or receiving chamber for the bulk material collecting container and, for example, a pump associated with the bulk material collecting container. In addition, the liquid collecting tank finds place in the sewer manhole. However, since the liquid collecting container is an integral and partial component of the sewer manhole or is designed as such according to the invention, the sewer manhole according to the invention (at least in part) at the same time assumes the function of the liquid collecting tank.

Tatsächlich ist der Flüssigkeits-Sammelbehälter im Allgemeinen fußseitig des Abwasserschachtes ausgebildet. D. h., der fußseitige Bereich des Abwasserschachtes fungiert als Flüssigkeits-Sammelbehälter. Auf diese Weise wird der fußseitige Bereich des Abwasserschachtes als Flüssigkeits-Sammelbehälter genutzt und ist ein separat herzustellender Flüssigkeits-Sammelbehälter mit den damit verbundenen nicht unerheblichen Investitionskosten entbehrlich.In fact, the liquid reservoir is generally formed at the foot end of the sewer well. D. h., The foot-side portion of the sewer manhole acts as a liquid reservoir. In this way, the foot-side region of the sewer manhole is used as a liquid collecting container and a separately produced liquid collecting container with the associated not inconsiderable investment costs is unnecessary.

Auf diese Weise ist der Abwasserschacht im Allgemeinen bis zu einem vorgegebenen maximalen Flüssigkeitsspiegel mit vorgereinigtem Abwasser unter Definition des Flüssigkeits-Sammelbehälters gefüllt. Tatsächlich wird nämlich das Abwasser im Regelfall über einen Zulaufverteiler dem Sperrstoff-Sammelbehälter zugeführt. Der Sperrstoff-Sammeibehälter ist in einem eigenen Gehäuse realisiert, welches in seinem Innern das einleitend bereits angesprochene Trennsieb aufweist. Das Trennsieb unterteilt den Sperrstoff-Sammelbehälter in den sperrstoffbelasteten Behälterbereich und den sperrstofffreien Behälterbereich. Lediglich der sperrstofffreie Behälterbereich kommuniziert mit dem Flüssigkeits-Sammelbehälter, so dass ausschließlich vorgereinigtes Abwasser unter Definition des Flüssigkeits-Sammelbehälters in den Abwasserschacht gelangt.In this way, the sewer manhole is generally filled to a predetermined maximum liquid level with pre-treated wastewater defining the liquid receiver. In fact, the wastewater is usually fed via a feed distributor to the bulk material collecting container. The bulking-Sammeibehälter is realized in a separate housing, which has in its interior already mentioned initially separating sieve. The dividing screen subdivides the bulk material collecting container into the container area which is loaded with a barrier substance and the container area which is impermeable to the substance. Only the barrier-free container area communicates with the liquid collecting container, so that only pre-cleaned wastewater passes under definition of the liquid collecting container in the sewer manhole.

Die wenigstens eine dem Sperrstoff-Sammelbehälter zugeordnete Pumpe befindet sich nun ganz oder teilweise im Pumpensumpf des Abwasserschachtes. Dieser Pumpensumpf wird von dem vorgereinigten Abwasser gebildet, welches den Abwasserschacht fußseitig füllt und den Flüssigkeits-Sammelbehälter definiert, der gleichsam in den Abwasserschacht integriert ist. Bei der dem Sperrstoff-Sammelbehälter zugeordneten Pumpe handelt es sich folglich um eine Tauchpumpe. Eine derartige Tauchpumpe ist meistens als (Kreisel-)Pumpe ausgelegt, .welche in die zu fördernde Flüssigkeit eingetaucht wird, vorliegend in das vorgereinigte Abwasser.The at least one pump associated with the bulk material collecting tank is now located wholly or partially in the pump sump of the wastewater shaft. This pump sump is formed by the pre-treated waste water, which fills the sewer manhole and defines the liquid collecting tank, which is integrated into the sewer manhole. The pump associated with the bulk material collecting tank is therefore a submersible pump. Such a submersible pump is usually designed as a (centrifugal) pump, which is immersed in the liquid to be conveyed, in this case in the pre-cleaned wastewater.

Während die Pumpe bzw. Tauchpumpe ganz oder teilweise in das vorgereinigte Abwasser eintaucht, befindet sich der äperrstoff-Sammelbehälter im Regelfall oberhalb des maximalen Flüssigkeitsspiegels im Innern des Abwasserschachtes. Das ist natürlich selbstverständlich nicht zwingend. Denn der Sperrstoffsammelbehälter ist üblicherweise geschlossen ausgeführt, so dass er auch in der Flüssigkeit unterhalb des maximalen Flüssigkeitsspiegels angeordnet werden kann.While the pump or submerged pump dives completely or partially in the pre-cleaned wastewater, the non-contaminant collecting container is usually above the maximum liquid level inside the sewer manhole. Of course, this is not mandatory. Because the bulk material collection container is usually designed to be closed, so that it can also be arranged in the liquid below the maximum liquid level.

Vergleichbares gilt für den dem Sperrstoff-Sammelbehälter vorgeschalteten Zulaufverteiler. Auch dieser findet sich in der Regel oberhalb des maximalen Flüssigkeitsspiegels, um beispielsweise etwaige Wartungs- oder Reinigungsarbeiten zu erleichtern. Auch in diesem Fall ist eine Anordnung des Zulaufverteilers in der Flüssigkeit denkbar, weil der Zulaufverteiler ebenfalls geschlossen ausgebildet ist. Tatsächlich verfügt der Zulaufverteiler im Allgemeinen über einen Notüberlauf und ist mit Hilfe dieses Notüberlaufes mit dem Flüssigkeits-Sammelbehälter verbunden.The same applies to the upstream of the bulk material collection container inlet manifold. Again, this is usually above the maximum liquid level, for example, to facilitate any maintenance or cleaning work. Also in this case, an arrangement of the inlet manifold in the liquid is conceivable because the inlet manifold is also formed closed. In fact, the supply manifold generally has an emergency overflow and is connected to the liquid reservoir by means of this emergency overflow.

Die Pumpe bzw. Tauchpumpe ist über wenigstens eine Verbindungsleitung mit dem Sperrstoff-Sammelbehälter verbunden. Diese Verbindungsleitung befindet sich im Allgemeinen zumindest teilweise im Pumpensumpf. Meistens sind zwei Verbindungsleitungen realisiert, die einerseits an den sperrstofffreien und andererseits den sperrstoffbelasteten Bereich des Sperrstoff-Sammelbehälters angeschlossen sind.The pump or submersible pump is connected via at least one connecting line with the bulk material collecting container. This connecting line is generally located at least partially in the pump sump. In most cases, two connecting lines are realized, which are connected on the one hand to the barrier-free and on the other hand the cut-off material loaded area of the bulk material collecting container.

Ferner ist noch eine bzw. sind zwei Druckleitungen vorgesehen, welche den Sperrstoff-Sammelbehälter und/oder den Flüssigkeits-Sammelbehälter mit beispielsweise einer nachgeschalteten Abwasserbehandlungsanlage verbinden. Denn die beschriebene Abwasserhebeanlage dient beispielsweise dazu, das hierdurch hindurchgeführte Abwasser auf ein bestimmtes Niveau zu heben, damit dieses anschließend in der Abwasserbehandlungsanlage bzw. einer Abwasserreinigungsanlage weiterbehandelt werden kann.Furthermore, one or two pressure lines are still provided which connect the bulk material collecting container and / or the liquid collecting container with, for example, a downstream waste water treatment plant. Because the wastewater lifting plant described serves, for example, to raise the wastewater passed through to a certain level, so that this can then be further treated in the wastewater treatment plant or a wastewater treatment plant.

Als besonderer Vorteil ergibt sich, dass der Abwasserschacht als vorhandener und/oder vorgefertigter Hohlraum ausgebildet ist. Dieser Hohlraum kann beispielsweise mit vorhandenen und gemauerten Wänden ausgekleidet sein. Daneben sind aber auch Wände aus Kunststoff und/oder Stahl bzw. vergleichbaren Materialien alternativ oder zusätzlich denkbar. Dadurch können vorhandene Abwasserschächte mit der erfindungsgemäßen Abwasserhebeanlage ausgerüstet bzw. nachgerüstet werden. In jedem Fall lässt sich der Flüssigkeits-Sammelbehälter anlagentechnisch einsparen, was zu deutlichen Kostenvorteilen gegenüber bisherigen Vorgehensweisen korrespondiert. Dadurch lassen sich bestehende Abwasserhebeanlagen problemlos sanieren und kann der vorhandene Abwasserschacht vorteilhaft genutzt werden. Hierin sind die wesentlichen Vorteile zu sehen.A particular advantage is that the sewer manhole is designed as an existing and / or prefabricated cavity. This cavity may for example be lined with existing and brick walls. In addition, however, walls made of plastic and / or steel or comparable materials are alternatively or additionally conceivable. As a result, existing wastewater shafts can be equipped or retrofitted with the wastewater lifting plant according to the invention. In any case, the liquid collecting tank can be saved plant technology, which corresponds to significant cost advantages over previous approaches. As a result, existing sewage lifting systems can be rehabilitated easily and the existing sewer manhole can be used advantageously. Here are the main benefits.

im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Die einzige Figur zeigt eine erfindungsgemäße Abwasserhebeanlage in schematischem Schnitt.In the following, the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. The single FIGURE shows a wastewater lifting plant according to the invention in a schematic section.

In der Figur ist eine Abwasserhebeanlage dargestellt, die in ihrem grundsätzlichen Aufbau in einem Abwasserschacht 1 lokalisiert ist. Zu der Abwasserhebeanlage gehören wenigstens ein Sperrstoffsammel-Behälter 2 sowie ein Flüssigkeits-Sammeibehälter 3 und schließlich noch wenigstens eine Pumpe 4. Des Weiteren ein Zulaufverteiler 5, welcher allerdings grundsätzlich entbehrlich ist.In the figure, a wastewater lifting plant is shown, which is located in its basic structure in a sewer manhole 1. The wastewater lifting plant includes at least one bulk substance collecting container 2 and a liquid collecting container 3 and finally at least one pump 4. Furthermore, an inlet distributor 5, which, however, is basically dispensable.

Der Sperrstoff-Sammelbehälter 2, der Flüssigkeits-Sammelbehälter 3, die Pumpe 4 und schließlich der Zulaufverteiler 5 werden zusammen genommen als Anlagenteile 2, 3, 4, 5 in dem Abwasserschacht 1 aufgenommen bzw. von dem Abwasserschacht 1 eingehaust. Der Sperrstoff-Sammelbehälter 2 verfügt über ein eigenes Gehäuse mit darin befindlichem und lediglich angedeuteten Trennsieb 6. Anstelle oder zusätzlich zu diesem Trennsieb kann auch eine kombinierte Absperr-/Siebeinrichtung realisiert werden. Jedenfalls ist der Sperrstoff-Sammelbehälter 2 in einen sperrstoffbelasteten Behälterbereich 2a und einen sperrstofffreien Behälterbereich 2b unterteilt.The bulk material collecting container 2, the liquid collecting container 3, the pump 4 and finally the feed distributor 5 are taken together taken as plant parts 2, 3, 4, 5 in the sewer manhole 1 or housed by the sewer manhole 1. The bulk material collecting container 2 has its own housing with a dividing sieve 6 located therein and merely indicated. Instead of or in addition to this dividing sieve, a combined shut-off / sieve device can also be realized. In any case, the bulk material collecting container 2 is subdivided into a container area 2 a which is loaded with a barrier substance and a container area 2 b without a barrier material.

Man erkennt, dass der Flüssigkeits-Sammelbehälter 3 in dem Abwasserschacht 1 als dessen teilweiser und integraler Bestandteil ausgebildet ist. Auf diese Weise übernimmt der Abwasserschacht 1 eine zweifache Funktion. Zunächst einmal dient er zur Aufnahme bzw. zur Einhausung der Anlagenteile 2, 3, 4, 5 im Beispielfall und darüber hinaus zur Definition des Flüssigkeits-Sammelbehälters 3, dessen separate Auslegung und Fertigung folglich erfindungsgemäß entbehrlich ist.It can be seen that the liquid collecting container 3 is formed in the sewer manhole 1 as its partial and integral component. In this way, the sewer manhole 1 assumes a dual function. First of all, it serves for receiving or enclosing the plant parts 2, 3, 4, 5 in the example case and beyond to the definition of the liquid collecting container 3, the separate design and manufacture is therefore unnecessary according to the invention.

Tatsächlich wird der Flüssigkeits-Sammelbehälter 3 fußseitig des Abwasserschachtes 1 ausgebildet. Der Abwasserschacht 1 ist folglich bis zu einem vorgegebenen maximalen Flüssigkeitsspiegel S mit vorgereinigtem Abwasser unter Definition des Flüssigkeits-Sammelbehälters 3 gefüllt.In fact, the liquid collecting tank 3 is formed at the foot of the sewage pit 1. The sewage shaft 1 is consequently filled up to a predetermined maximum liquid level S with prepurified wastewater with definition of the liquid collecting container 3.

Dem Sperrstoff-Sammeibehäiter 2 ist die Pumpe 4 zugeordnet. Bei der Pumpe 4 handelt es sich um eine Tauchpumpe, die als Kreiselpumpe ausgebildet sein mag. Die Pumpe bzw. Tauchpumpe 4 ist ganz oder teilweise im Pumpensumpf angeordnet, welcher sich fußseitig des Abwasserschachtes 1 bis zur Höhe des Flüssigkeitsspiegels S an vorgereinigtem Abwasser ausbildet.The bulky Sammeibehäiter 2, the pump 4 is assigned. The pump 4 is a submersible pump, which may be designed as a centrifugal pump. The pump or submersible pump 4 is wholly or partially disposed in the pump sump, which forms the foot side of the sewer manhole 1 to the level of the liquid level S pre-cleaned wastewater.

Im Gegensatz zur Pumpe bzw. Tauchpumpe 4 findet sich der Sperrstoff-Sammelbehälter 2 oberhalb des maximalen Flüssigkeitsspiegels S. Auch ist der Zulaufverteiler 5 oberhalb des fraglichen maximalen Flüssigkeitsspiegels S angeordnet. Eine solche Anordnung empfiehlt sich, um das im Zulaufverteiler 5 sowie dem Sperrstoff-Sammeibehälter 2 befindliche und mit Sperrstoffen F belastete Abwasser nicht mit dem im Flüssigkeits-Sammelbehälter 3 vorhandenen sowie vorgereinigtem Abwasser zu vermischen.In contrast to the pump or submersible pump 4 is the bulk material reservoir 2 above the maximum liquid level S. Also, the Inlet manifold 5 above the questionable maximum liquid level S arranged. Such an arrangement is advisable not to mix in the feed manifold 5 and the bulk material Sammeibehälter 2 and loaded with blocking substances F wastewater with existing in the liquid collecting tank 3 and pre-cleaned wastewater.

Der Zulaufverteiler 5 ist dem Sperrstoff-Sammelbehälter 2 vorgeschaltet. Über den Zulaufverteiler 5 gelangt mit Sperrstoffen F belastetes Abwasser über eine Koppelleitung 7 in den Sperrstoff-Sammelbehälter 2. Durch das dort vorhandene Trennsieb 6 werden die Sperrstoffe F in dem sperrstoffbelasteten Behälterbereich 2a zurückgehalten und lediglich von Sperrstoffen F befreites und vorgereinigtes Abwasser fließt den Pfeilen folgend über den sperrstofffreien Behälterbereich 2b und einen Bypass 9 zu einer Verbindungsleitung 8 in die Pumpe 4 und von dort aus in den Flüssigkeits-Sammelbehälter 3.The feed distributor 5 is connected upstream of the bulk material collecting container 2. Through the feed distributor 5 polluted wastewater F loaded via a coupling line 7 in the bulk material collection container 2. By the existing separation screen 6, the barrier materials F are retained in the contaminated container portion 2a and only freed of blocking substances F and pre-cleaned wastewater flows following the arrows via the impermeable container area 2b and a bypass 9 to a connecting line 8 in the pump 4 and from there into the liquid collecting container 3rd

Im Rahmen des Ausführungsbeispiels und nicht einschränkend ist der Bypass 9 an den sperrstofffreien Behälterbereich 2b angeschlossen, während die Verbindungsleitung 8 mit dem sperrstoffbelasteten Behälterbereich 2a kommuniziert, der seinerseits ausgangsseitig an eine Druckleitung 10 angeschlossen ist. Zusätzliche und beispielsweise im Innern des Sperrstoff-Sammelbehälters 2 vorgesehene Klappen sorgen dafür, dass der Strom des Abwassers wie nachfolgend beschrieben definiert wird.Within the scope of the exemplary embodiment and not limitation, the bypass 9 is connected to the non-barrier container area 2b, while the connecting line 8 communicates with the container area 2a which is loaded with a barrier material, which in turn is connected on the output side to a pressure line 10. Additional and provided, for example inside the bulk material collection container 2 flaps ensure that the flow of sewage is defined as described below.

Tatsächlich wird der Sperrstoff-Sammelbehälter 2 über den Zulaufverteiler 5 mit dem mit Grobstoffen oder Feststoffen F belasteten Abwasser beschickt. Das Trennsieb 6 im Innern des Sperrstoff-Sammelbehälters 2 sorgt für die bereits beschriebene Grobreinigung des mit Sperrstoffen F belasteten Abwassers. Grundsätzlich kann auf ein solches Trennsieb 6 natürlich auch verzichtet werden. In diesem Fall ist die bereits angesprochene Absperr-/Siebeinrichtung beispielhaft vorgesehen. Hierbei handelt es sich üblicherweise um eine Baueinheit aus einer Absperrklappe und einem Sieb.In fact, the bulk material collecting container 2 is fed via the feed distributor 5 with the wastewater loaded with coarse matter or solids F. The separating sieve 6 in the interior of the bulky substance collecting container 2 ensures the already described coarse cleaning of the wastewater contaminated with blocking substances F. In principle, such a separating screen 6 can of course also be dispensed with. In this case, the already mentioned shut-off / screening device provided by way of example. This is usually a structural unit of a butterfly valve and a sieve.

Die fragliche Absperr-/Siebeinrichtung mag anstelle der in der Figur angedeuteten Klappe einlaufseitig der Verbindungsleitung 8 realisiert werden. Dabei kann eine vergleichbare Absperr-/Siebeinrichtung zum Einsatz kommen, wie sie in dem Gebrauchsmuster DE 20 2008 011 273 U1 der Anmelderin beschrieben wird. Grundsätzlich sind natürlich auch mehrere Absperr-/Siebeinrichtungen denkbar. Außerdem kann die Absperr-/Siebeinrichtung mit dem Trennsieb 6 bei Bedarf kombiniert werden. So oder so sammelt sich das vorgereinigte Abwasser im Flüssigkeits-Sammelbehälter 3 als integralen Bestandteil des Abwasserschachtes 1. Bei diesem Vorgang mag die Pumpe 4 durchströmt werden, kann aber auch saugend arbeiten.The shut-off / screening device in question may be realized instead of the flap indicated in the figure on the inlet side of the connecting line 8. In this case, a comparable shut-off / screening device can be used, as in the utility model DE 20 2008 011 273 U1 the applicant is described. In principle, of course, several shut-off / screening devices are conceivable. In addition, the shut-off / screening device can be combined with the separating sieve 6 if necessary. Either way, the pre-cleaned wastewater collects in the liquid collecting tank 3 as an integral part of the sewage shaft 1. In this process, the pump 4 may be flowed through, but can also work suction.

Das vorgereinigte und im Flüssigkeits-Sammelbehälter 3 aufgefangene Abwasser kann nun mit Hilfe der Pumpe bzw. Tauchpumpe 4 über den Bypass 9 und die Verbindungsleitung 8 durch den Sperrstoff-Sammelbehälter 2 in die Druckleitung 10 überführt werden. Bei diesem Vorgang werden die zuvor auf dem Trennsieb 6 befindlichen Sperrstoffe F vom Trennsieb 6 losgespült. Die Pumpe bzw. Tauchpumpe 4 fördert lediglich vorgereinigtes Abwasser und kann deshalb von ihrer Auslegung her hieran angepasst werden.The pre-cleaned and collected in the liquid collecting tank 3 wastewater can now be transferred by means of the pump or submersible pump 4 via the bypass 9 and the connecting line 8 through the bulk material collecting container 2 in the pressure line 10. In this process, the previously located on the screen 6 barrier materials F are rinsed from the separation screen 6. The pump or submersible pump 4 only promotes pre-treated wastewater and can therefore be adapted to their interpretation of this.

Über die Druckleitung 10 gelangt das Abwasser zu einer beispielsweise nachgeschalteten und nicht dargestellten Abwasserbehandlungsanlage. Anhand des Ausführungsbeispiels erkennt man, dass die Druckleitung 10 auch direkt mit Hilfe der Pumpe 4 von dem Flüssigkeits-Sammelbehälter 3 mit dort befindlichem vorgereinigtem Abwasser beschickt werden kann. Zu diesem Zweck kann eine separate und strichpunktiert angelegte weitere Druckleitung 11 vorgesehen sein, welche unmittelbar und ausgangsseitig an die Pumpe 4 unter Umgehung des Sperrstoff-Sammeibehälters 2 angeschlossen ist und in die Druckleitung 10 mündet.About the pressure line 10, the wastewater passes to an example downstream and not shown wastewater treatment plant. Based on the embodiment, it can be seen that the pressure line 10 can also be fed directly by means of the pump 4 from the liquid collecting container 3 with pre-cleaned wastewater located there. For this purpose, a separate and dash-dot applied further pressure line 11 may be provided, which directly and the output side to the pump 4 below Bypassing of the bulk material Sammeibehälters 2 is connected and opens into the pressure line 10.

Eine solche Vorgehensweise empfiehlt sich für den Fall, dass der Zulaufverteiler 5 beispielsweise mit dem einleitend bereits beschriebenen Überlauf respektive Notüberlauf ausgerüstet ist. Dadurch erfolgt beispielsweise bei einem verstopfungsbedingten Ausfall des Sperrstoff-Sammeibehälters. 2 die direkte Zufuhr des mit Sperrstoffen belasteten Abwassers über den Notüberlauf zum Flüssigkeits-Sammelbehälter 3. Von da aus kann dann das fragliche Abwasser mit Hilfe der Druckleitung 11 in die Druckleitung 10 weggefördert werden.Such a procedure is recommended for the case that the inlet manifold 5 is equipped, for example, with the already described above overflow or emergency overflow. As a result, for example, in a blockage-related failure of the bulk storage container. 2, the direct supply of wastewater contaminated with blocking substances via the emergency overflow to the liquid collecting tank 3. From there, the wastewater in question can then be conveyed away by means of the pressure line 11 into the pressure line 10.

Man erkennt, dass die Verbindungsleitung 8 bzw. die Verbindungsleitungen 8, 9, über welche die Pumpe 4 mit dem Sperrstoff-Sammelbehälter 2 kommuniziert, wenigstens teilweise im Pumpensumpf angeordnet ist bzw. sind. Der Pumpensumpf wird von dem vorgereinigten und fußseitig im Abwasserschacht 1 aufgenommenen Abwasser gebildet. Die Druckleitung 10 bzw. die Druckleitung 11 verbindet den Sperrstoff-Sammelbehälter 2 und/oder den Flüssigkeits-Sammeibehälter 3 mit der bereits angesprochenen Abwasserbehandlungsanlage.It can be seen that the connecting line 8 or the connecting lines 8, 9, via which the pump 4 communicates with the bulk material collecting container 2, is or are arranged at least partially in the pump sump. The pump sump is formed by the pre-cleaned and recorded at the bottom of the sewer manhole 1 wastewater. The pressure line 10 or the pressure line 11 connects the bulk material collecting container 2 and / or the liquid collecting container 3 with the already mentioned wastewater treatment plant.

Der Abwasserschacht 1 kann als vorhandener Hohlraum ausgebildet sein, der im Rahmen einer Sanierung mit der beschrieben Abwasserhebeanlage in seinem Innern ausgerüstet wird. In diesem Fall verfügt der Abwasserschacht 1 beispielsweise über gemauerte Wände. Selbstverständlich können die Wände aber auch aus Kunststoff, Stahl oder anderen Materialien sowie Kombinationen hergestellt werden.The sewage shaft 1 may be formed as an existing cavity, which is equipped in the context of a renovation with the described sewage lifting plant in its interior. In this case, the sewer manhole 1, for example, has masonry walls. Of course, the walls can also be made of plastic, steel or other materials and combinations.

Nicht ausdrücklich dargestellt ist die Möglichkeit, vorgereinigtes Abwasser direkt in den Flüssigkeits-Sammelbehälter 3 zu überführen - unter Umgehung der Verbindungsleitung 8 und ggf. des Bypasses 9. An dieser Stelle ist es denkbar, den Bypass 9 mit einem Umschaltorgan auszurüsten, welches wahlweise einen direkten Abfluss des vorgereinigten Abwassers in den Flüssigkeits-Sammelbehälter 3 einerseits und andererseits den Fluss des vorgereinigten Abwassers in die Druckleitung 10 zulässt. Dadurch lässt sich bei Bedarf die in den Flüssigkeits-Sammelbehälter 3 fließende Menge an vorgereinigtem Abwasser vergrößern, und zwar letztlich unter Umgehung der Pumpe 4.Not explicitly shown is the ability to transfer pre-treated wastewater directly into the liquid reservoir 3 - bypassing the connecting line 8 and possibly the bypass 9. At this point, it is conceivable to equip the bypass 9 with a changeover, which optionally a direct Outflow of prepurified wastewater into the liquid collecting container 3 on the one hand and on the other hand, the flow of pre-cleaned waste water into the pressure line 10 allows. As a result, if necessary, the amount of prepurified wastewater flowing into the liquid collecting container 3 can be increased, ultimately bypassing the pump 4.
