Description

Die Erfindung bezieht sich gattungsgemäß auf eine Anlage für die Aufbereitung von Abwasser nach dem Belebtschlammverfahren mit mehreren strömungsmäßig hintereinandergeschalteten, zueinander parallelen Stabilisierungsgräben, die durch zwischengeschaltete Kehren untereinander verbunden sind, und mit mehreren Belüftungseinrichtungen, in deren Bereich durch eine Überdeckung des Abwassers Oxidationskammern einer Sauerstoffbegasungsanlage gebildet sind.The invention relates generically to a system for the treatment of wastewater after Activated sludge process with several flow-wise sequentially connected, parallel to each other Stabilization trenches, which are connected to each other by intervening hairpin bends, and with several Ventilation facilities, in the area of which the waste water is covered with oxidation chambers an oxygen gas supply system are formed.

Bei den bereits vorgeschlagenen gattungsgemäßen Anlagen (DE-OS 28 00 034, DE-OS 28 OG 035) sind die Oxidationskammern bzw. die in diesen angeordneten Belüftungseinrichtungen im Bereich der geraden, zueinander parallelen Stabilisierungsgräben angeordnet und unabhängig voneinander gesteuert. Das bedeutet einen erheblichen baulichen Aufwand. Darüber hinaus ist ein erheblicher steuerungstechnischer Aufwand erforderlich.In the already proposed generic systems (DE-OS 28 00 034, DE-OS 28 OG 035) are the Oxidation chambers or the ventilation devices arranged in them in the area of the straight, Arranged parallel stabilization trenches and controlled independently of one another. That means a considerable structural effort. In addition, there is a considerable outlay in terms of control technology necessary.

Demgegenüber liegt die Erfindung die Aufgabe zugrunde, bei einer Anlage der in Rede stehenden Art den baulichen Aufwand zu reduzieren.In contrast, the invention is based on the object of a system of the type in question to reduce the structural effort.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß die Belüftungseinrichtungen zumindest an einem Ende der Stabilisierungsgräben im Bereich der nebeneinanderliegenden Kehren angeordnet sind. Das bedeutet, daß die Oxidationskammern als Kaskadenstufen der Sauerstoffbegasungsanlage hintereinandergeschaltet sind. Die Hintereinanderschaltung ergibt sich aus den beanspruchten Merkmalen in Verbindung mit dem Merkmal im einleitend behandelten Gattungsbegriff, wonach die Stabilisierungsgräben hintereinandergeschaltet sind.To solve this problem, the invention teaches that the ventilation devices at least at one end of the stabilization trenches are arranged in the area of the adjacent hairpin bends. That means, that the oxidation chambers are connected in series as cascade stages of the oxygen gas supply system are. The series connection results from the claimed features in connection with the Feature in the generic term treated in the introduction, according to which the stabilization trenches are connected in series.

Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung. Das gilt insbesondere bezüglich der Belüftungseinrichtungen. Sie bestehen nach bevorzugter Ausführungsform aus Oberflächenbelüftern, die mit Sauerstoff angereichertes Behandlungsgas in das Wasser eintragen. Die Belüftungseinrichtungen können aber auch als unter dem Abwasserspiegel angeordnete Druckgaseinführungsrohre ausgebildet sein, die an eine Sauerstoffbegasungsanlage angeschlossen sind.In particular, there are several possibilities for further training and within the scope of the invention Layout. This applies in particular to the ventilation devices. They are preferred Embodiment of surface aerators, the treatment gas enriched with oxygen in the Enter water. The ventilation devices can, however, also be arranged below the sewage level Be formed pressurized gas introduction pipes which are connected to an oxygen gas supply system.

Die erreichten Vorteile sind in der baulichen Vereinfachung zu sehen, weil die nach der Lehre der Erfindung insgesamt durchzuführenden Maßnahmen im Bereich der nebeneinanderliegenden Kehren einheitlich und baulich einfach verwirklicht werden können. Das gilt auch für die Belüftungseinrichtungen. Zugleich ergibt sich eine Verbesserung, weil die Oxidationskammern, steuerungstechr.isch einfach, als Kaskadenstufen der Sauerstoffbegasungsanlage wirksam sind.The advantages achieved can be seen in the structural simplification, because according to the teaching of the Invention overall measures to be carried out in the area of the adjacent turns uniformly and can be easily implemented structurally. This also applies to the ventilation systems. Simultaneously there is an improvement because the oxidation chambers, simply from a control point of view, are cascade stages the oxygen gas supply system are effective.

Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Es zeigtIn the following the invention is illustrated by means of a drawing which shows only one exemplary embodiment explained in more detail. It shows

Fig. 1 die erfindungsgemäße Anlage im Grundriß undFig. 1 shows the system according to the invention in plan and

Fig. 2 einen Schnitt in Richtung A-A durch den Gegenstand nach Fig. 1.FIG. 2 shows a section in the direction AA through the object according to FIG. 1.

In den F i g. 1 und 2 ist eine Belebungsstufe dargestellt, die aus einer Mehrzahl von strömungsmäßig unter Zwischenschaltung von Kehren 6 hintereinandergeschalteten, zueinander parallelen Stabilisierungsgräben 3 besteht und einen Zulauf 20 und einen Ablauf 20a aufweist. In den Kehren 6 dieser Gräben 3 sind an einer Seite im Grundriß nebeneinanderliegende Belüftungseinrichtungen 7 angeordnet. In the F i g. 1 and 2, an activation stage is shown, which consists of a plurality of flow-wise with the interposition of hairpin bends 6 stabilization trenches connected one behind the other and parallel to one another 3 consists and has an inlet 20 and an outlet 20a. In the bends 6 of these trenches 3 are at one Side in plan adjacent ventilation devices 7 arranged.

Die Stabilisierungsgräben 3 sind im Bereich der mit den Belüftungseinrichtungen 7 ausgerüsteten Kehren 6 durch Überdeckungen 8 zu Oxidationskammern 9, die zu einer Sauerstoffbegasungsanlage gehören, deren Sauerstofferzeugungsaggregate und Speicheraggregate (insgesamt 10) rechts neben Fig.2 angedeutet sind. Dabei bilden die einzelnen Oxidationskammern 9 Kaskadenstufen. Das deuten die eingezeichneten Pfeile 11 an. Damit die Oxidationskammern 9 zum freigebliebenen Teil der Stabilisierungsgräben 3 hin hinreichend gasdicht abgeschlossen sind, sind die Überdeckungen 8 der Oxidationskammern 9, die als einfache Platten ausgeführt sind, mit Stirnwänden 12 versehen, die in das aufzubereitende Abwasser gleichsam tauchtassenverschlußartig eintauchen. Im übrigen sind den Oxidationskammern 9 im Ausführungsbeispiel einströmseitig Fördereinrichtungen in Form von Rohrpropellern 13 vorgeschaltet.The stabilization trenches 3 are in the area of the turns 6 equipped with the ventilation devices 7 by overlaps 8 to oxidation chambers 9, which belong to an oxygen gassing system, whose Oxygen generating units and storage units (a total of 10) are indicated to the right of Fig.2. The individual oxidation chambers form 9 cascade stages. This is indicated by the arrows drawn 11 at. So that the oxidation chambers 9 to the remaining free If part of the stabilization trenches 3 are sealed in a sufficiently gas-tight manner, the overlaps 8 are the oxidation chambers 9, which are designed as simple plates, provided with end walls 12, which into the Immerse the wastewater to be treated, as it were, like an immersion cup. Otherwise, the oxidation chambers 9 are on the inflow side in the exemplary embodiment Conveying devices in the form of tubular propellers 13 are connected upstream.

In F i g. 1 mögen die mit 7 bezeichneten, als Kreise mit Kreuz angedeuteten Belüftungseinrichtungen Oberflächenbelüfter, ζ. B. Kreisel, sein. Es könnte sich jedoch auch um Druckgaseinführungseinrichtungen handeln, die dann über nicht gezeichnete Rohrleitungen an die Sauerstoffbegasungsanlage 10 angeschlossen sind. In Fig. 1 ist noch rechts oben dargestellt, daß die als Druckgaseinführungsrohre ausgeführten Belüftungseinströmungsmäßig 60 richtungen 7 auch im Bereich der Rohrpropeller 13 angeordnet sein können.In Fig. 1 like those marked with 7, as circles with Cross-indicated ventilation devices surface aerator, ζ. B. gyroscope. However, it could also act to pressurized gas introduction devices, which then via pipelines, not shown, to the Oxygen gas supply system 10 are connected. In Fig. 1 it is shown at the top right that the as Ventilation inflow 60 directions 7 also in the area of the tubular propeller 13 can be arranged.
