Description
Es ist bereits vorgeschlagen worden, Vorrichtungen zur biologischen Reinigung von Abwasser zu benutzen, die aus übereinander gestapelten Platten bestehen. Auf den Platten sind durch aufgesetzte Rippen oder auf andere Weise ganz bestimmte Strömungswege für das Abwasser festgelegt, und zwar derart, daß das Abwasser im Vergleich zu der Gesamtausdehnung der Platte in einem schmalen, ge-ο schlängelten Lauf in fortlaufendem Züge die ganze Oberfläche der Platte erfüllt. Das Abwasser fließt in verhältnismäßig dünner Schicht und mit nur geringem Gefälle, das meist sogar nur in der Querrichtung der Platten vorhanden ist, während die Platten in ihrer Längsrichtung kein Gefälle aufweisen. Es hat sich nun herausgestellt, daß eine besonders günstige Reinigungswirkung mit einer besonderen Form von Platten erzielt wird, die erfindungsgemäß so gestaltet sind, "daß das ,Abwasser abwechselnd in ganz dünner und in etwas dickerer Schicht über die Platten fließt. Zu diesem Zwecke werden zweckmäßig Vertiefungen oder Becken vorgesehen, in denen das Abwasser kleine Tümpel bildet und in denen sich der in dem Abwasser gebildete und die Reinigung unterstützende Schlamm sammeln kann, ohne daß die Gefahr besteht, daß dieser Schlamm abgeschwemmt wird.Devices have already been proposed to use for biological purification of wastewater that comes from one above the other stacked panels. On the plates are through attached ribs or on others Way very specific flow paths for the wastewater set, in such a way that the Sewage compared to the total extent of the plate in a narrow, ge-ο The whole surface of the plate was wound in a continuous course. The sewage flows in a relatively thin layer and with only a slight gradient, usually even exists only in the transverse direction of the panels, while the panels are in their longitudinal direction have no slope. It has now turned out that a particularly favorable cleaning effect with a special form of Plates is achieved according to the invention so are designed "that that, waste water alternately flows over the plates in a very thin and a slightly thicker layer. To this end Wells or basins are expediently provided in which the wastewater is small Pond forms and in which the water formed in the wastewater and which supports the cleaning process Can collect sludge without the risk that this sludge was washed away will.
Es hat sich ferner als vorteilhaft herausgestellt, auch an den flacheren Stellen des Abwasserweges den Boden der Platte nicht einfach eben verlaufen zu lassen, sondern mit Rippen zu versehen, die quer zur Strömungsrichtung verlaufen.It has also been found to be advantageous, even in the flatter areas of the Sewage path not just to let the bottom of the plate run flat, but with To provide ribs that run transversely to the direction of flow.
Die vertieften Becken und die Querrippen werden gleich an der Platte angeformt, die beispielsweise aus Asbestzement bestehen kann, die dann gleichzeitig als Auflager beim Aufbauen des Plattenstapels dienen können.The recessed basin and the transverse ribs are molded onto the plate that For example, it can consist of asbestos cement, which then simultaneously acts as a support when building of the plate stack can serve.
Im folgenden wird die Erfindung an Hand der beiliegenden Zeichnungen; an einem Ausführungsbeispiel beschrieben.In the following the invention is illustrated by hand of the accompanying drawings; in one embodiment described.
Fig. ι zeigt einen Längsschnitt durch zwei aufeinanderfolgende Platten;Fig. Ι shows a longitudinal section through two successive plates;
Fig. 2 ist eine Draufsicht auf einen Ausschnitt aus einer Platte.Fig. 2 is a plan view of a section from a plate.
In der Platte 48 wird durch Längsrippen 49 ein geschlängelter Weg für das Abwasser geschaffen. Der Wasserspiegel ist in Fig. 1 bei α b angedeutet. An dem Boden der Platte sind eine Reihe von Becken 50 angeformt, die gleichzeitig als Auflager für die Platte 48 dienen und auf den Rippen 52 der darunterliegenden Platte aufliegen. Quer zur Strömungsrichtung wird der glatte Verlauf des Bodens des jewei- !igen Wasserweges durch Querrippen 51 unterbrochen. Diese Querrippen wirken ähnlich wie kleine Wehre.In the plate 48 a winding path for the sewage is created by longitudinal ribs 49. The water level is indicated in Fig. 1 at α b. A number of basins 50 are formed on the bottom of the plate, which at the same time serve as supports for the plate 48 and rest on the ribs 52 of the plate below. The smooth course of the bottom of the respective waterway is interrupted by transverse ribs 51 at right angles to the direction of flow. These cross ribs act like small weirs.
Mittels dieser Vorrichtung kann ein ver- go bessertes Reinigungsverfahren durchgeführt werden. Das Abwasser fließt nicht nur in stets gleichbleibend dünner Schicht, sondern es bilden sich längs des Wasserlaufs kleine Tümpel, in denen sich der Schlamm besonders gut entwickeln kann und auch gegen vorzeitiges Abschwemmen gesichert ist. Die Unterbrechungen in der Strömung, die durch die Rippen 51 hervorgerufen werden, bewirken eine mit einer kleinen Strudelbildung vergleichbare Erschei- 7„ nung, die ebenfalls günstig für die Reinigung des Abwassers wirkt.An improved cleaning process can be carried out by means of this device. The wastewater not only flows in a consistently thin layer, but small pools are formed along the watercourse, in which the sludge can develop particularly well and is also protected against premature washing away. The interruptions in the flow that are caused by the ribs 51, causing a similar appearance with a small vortex formation 7 "planning, which acts also favorable for the cleaning of waste water.
