Description

Denitrifikations- und Nachklärbecken in Fertigelement-Denitrification and secondary clarifier in prefabricated element

bauweise Die Erfindung dient der Denitrifikation und Trennung von Wasser und Belebtschlamm in biologischen Kläranlagen.construction The invention is used for denitrification and separation of Water and activated sludge in biological sewage treatment plants.

Die bekannten Nachklärbecken mittlerer und grösserer biologischer Kläranlagen werden üblicherweise den erforderlichen Grössen entsprechend bemessen und vorzugsweise aus Stahlbeton konventionell hergestellt. Damit sind sie in Ihrer Leistung begrenzt und nur mit verhältnismässig grossem finanziellen und zeitlichen Aufwand zu erweitern.The well-known secondary clarifiers, medium-sized and larger biological ones Sewage treatment plants are usually dimensioned according to the required sizes and preferably made conventionally from reinforced concrete. With that they are in yours Achievement limited and only with a relatively large financial and time To expand effort.

Denitrifikationszonen als in NK-Becken integrierte Einbauteile sind nicht bekannt. Fast alle grösseren NK-Anlagen sind als längsdurchströmte runde Flachbecken mit motorisch angetriebenen Schlammräumbrücken ausgebildet.Denitrification zones are built-in parts that are integrated into MT basins not known. Almost all larger NK systems are designed as round flat basins with longitudinal flow designed with motor-driven sludge removal bridges.

Diese Becken lassen sich schwer abdecken und sind bei anhaltend tiefem Frost eisgefährdet, wenn die Vorlauftemperatur des Belebtschlammgemisches stark abgesunken ist.These basins are difficult to cover and are at persistently deep Frost risk if the flow temperature of the activated sludge mixture is high has sunk.

Aufgabe der Erfindung war es, eine leicht abdeckbare und problemlos erweiterbare NK-Anlage ohne mechanische Schlammräumnung mit integrierter Denitrifikationszone zu schaffen, bei der erforderlichen Bewegungsmechanismen mit der Fliessenergie des Belebtschlammwassergemisches betrieben werden.The object of the invention was to provide an easily coverable and problem-free Expandable MT plant without mechanical sludge removal with integrated denitrification zone to create the necessary movement mechanisms with the flow energy of the Activated sludge water mixtures are operated.

Die Aufgabe wird erfinderisch dadurch gelöst, dass vorgefertigte, rinnenförmige Fertigteile (1), die problemlos zu transportieren sind und mit den Kopfstücken zu einem rechteckigen Becken der erforderichen Grösse aneinander greiht werden. In das V-förmige Becken werden zwei Tauchwände (2) eingehängt, sodass drei Zonen (4) (5) entstehen, von denen die mittlere (4) der Denitrifikation und die beide äusseren (5) der Wasser-Schlammreinigung zugeordnet sind. Die Volumina der drei Zonen sowie die Oberfläche der NK-Zonen sind aufeinander und auf die Bemessungsrichtlinien abgestimmt.The object is achieved according to the invention in that prefabricated, Channel-shaped prefabricated parts (1) that are easy to transport and with the Head pieces lined up to form a rectangular basin of the required size will. Two baffles (2) are hung in the V-shaped basin, so that three Zones (4) (5) arise, of which the middle (4) of denitrification and the both outer (5) are assigned to the water-sludge cleaning. The volumes of the three zones as well as the surface of the NK zones are on top of each other and on the design guidelines Voted.

Das aus dem Belebungs- und Belüftungsbecken der biologischen Kläranlage kommende Belebtschlammgemisch wird über die Auslauföffnungen der längs und mittig über der DNK liegenden Verteilerrinne auf die in jedem Element angeordneten Drehteller (8) geleitet und treibt durch Aufprall auf die Flügelaufkantungen das unter dem Drehteller angeordnete Rührwerk (9) an.That from the aeration and aeration basin of the biological sewage treatment plant Coming activated sludge mixture is through the outlet openings of the longitudinal and center The distributor channel located above the DNK on the turntable in each element (8) and drives the under the wing upstand by impact Rotary plate arranged agitator (9).

Das Belebtschlammgemisch verlässt die Denitrifikationszone (4) unter den Tauchwänden (2) hindurch in die Nachklärzonen (5), wo in der verzögerlichen Aufströmumng der Belebtschlamm sedimentiert wird und das Klarwasser über Zackenrinnen (10) am oberen Beckenrand abläuft.The activated sludge mixture leaves the denitrification zone (4) below the baffles (2) through into the final clarification zones (5), where in the delayed Aufströmumng the activated sludge is sedimented and the clear water via serrated channels (10) runs off the upper edge of the pool.

Der sedimentierte Schlamm wird über die hydrostatische höhenverstellbare Sedimentabzugsanlage (11) (DE 2843867 A) abgezogen und als Rücklaufschlamm den Belebungsbecken wieder zugeführt. Eine Teilmenge wird als Uberschuss-Schlamm abgenommen.The sedimented sludge is height-adjustable via the hydrostatic Sediment extraction system (11) (DE 2843867 A) withdrawn and the activated sludge tank as return sludge fed back. A partial amount is taken off as excess sludge.

Evtl. anfallender Schwimmschlamm wird über Schwimmschlammabzugsrinnen (12), die mechanisch unter die Wasserspiegelhöhe abgesenkt werden, abgezogen und der Sedimentabzugsanlage (11) zugeleitet.Any scum sludge is removed via scum drainage channels (12), which are mechanically lowered below the water level, deducted and fed to the sediment extraction system (11).

Alle Einbauten sind vorgefertigte Teile und auf die Beckenelemente masslich abgestimmt.All fixtures are prefabricated parts and on the pool elements massively coordinated.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel erläutert, das in der anliegenden Zeichnung dargestellt ist.The invention is explained below using an exemplary embodiment, which is shown in the accompanying drawing.

Figur 1 zeigt in der Draufsicht einen Teilausschnitt des Denitrifikations- und Nachklärbeckens.Figure 1 shows a top view of a partial section of the denitrification and secondary clarifier.

Figur 2 zeigt den Querschnitt des DNK.Figure 2 shows the cross section of the DNK.

Figur 3 zeigt den Längsschnitt eines Teilausschnittes des DNK.Figure 3 shows the longitudinal section of a partial section of the DNK.
