Abstract
Description
Patentansprüche: 1. Vorrichtung zum Spülen eines zur biologischen Abwasserbehandlung verwendbaren Füllgutes in eingebautem Zustand, dadurch gekennz e i c h n e t, daß durch gelochte oder geschlitzte Rohre gebildete Spülrohre (1) vertikal in dem Füllgut (2) eines Tropfkörpers eingebracht und mit Spülwasser beaufschlagbar sind. Claims: 1. Device for rinsing a biological Filling goods that can be used for waste water treatment in the installed state, thereby marked e i c h e t that flushing pipes (1) formed by perforated or slotted pipes placed vertically in the filling material (2) of a trickling filter and exposed to rinsing water are.
2 Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß das obere Ende der Spülrohre (1) außerhalb ihres Gebrauches gegen den Eintritt von Schmutzpartikeln mit einer Lüftungshaube (4) verschließbar ist 3. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß durch Abgrenzung des Spülwasseraustritts aus dem Spülrohr (1) mit Hilfe von höhenverstellbaren Fuß- und Kopfstopfen mit Druckwasseranschluß (5 und 6) die Spülwirkung örtlich verstärkt ist Die Erfindung betrifft eine Vorrichtung zum Spülen eines zur biologischen Abwasserbehandlung verwendbaren Füllgutes in eingebautem Zustand. 2 Device according to claim 1, characterized in that the upper End of the flushing pipes (1) outside of their use against the entry of dirt particles 3. Device according to claim 1, characterized in that it can be closed with a ventilation hood (4) characterized in that by delimiting the flushing water outlet from the flushing pipe (1) with the help of height-adjustable foot and head plugs with pressurized water connection (5 and 6) the flushing action is locally enhanced. The invention relates to an apparatus for rinsing a product that can be used for biological wastewater treatment in a built-in State.
Spülrohre dieser Art sind beispielsweise durch die AT-PS 329465 bekanntgeworden. Diese bekannten Spülrohre sind in einer Reihe senkrecht an Dreharmen befestigt und werden zum Spülen kreisförmig durch das Füllgut bewegt. Flushing pipes of this type have become known, for example, from AT-PS 329465. These known flushing pipes are attached in a row and perpendicular to rotating arms are moved in a circle through the product for rinsing.
Die Vorrichtung eignet sich zum Spülen eines Füllgutes von geringer Dichte und Korngröße, wenn darüber hinaus durch Aufstauen von Wasser ein Schwebezustand des Füllgutes erzielt wird. Der zur Reinigung des Füllgutes erforderliche Spüleffekt wird unter diesen Voraussetzungen durch das Einpressen von Druckluft bewirkt und das Schmutzwasser durch besondere Vorrichtungen von der Oberfläche abgezogen. The device is suitable for rinsing a product of less Density and grain size if, in addition, a suspension due to damming up of water of the product is achieved. The rinsing effect required to clean the product is effected under these conditions by the injection of compressed air and the dirty water is drawn off the surface using special devices.
Bei den zur biologischen Abwasserbehandlung speziell in Tropfkörpern entsprechend der DIN 19 557 verwendeten Füllstoffen sowie der Ausführung der Behälter gemäß DIN 19553 ist jedoch der Einsatz der bekannten Vorrichtung zum Spülen des Füllgutes nicht möglich. In the case of biological wastewater treatment, especially in trickling filters fillers used in accordance with DIN 19 557 and the design of the containers according to DIN 19553, however, the use of the known device for flushing the Contents not possible.
Der Erfindung liegt die Aufgabe zugrunde, das Füllgut eines Tropfkörpers in eingebautem Zustand von Verstopfungen verursachenden Ablagerungen zu befreien. The invention is based on the object of the filling material of a trickling filter free of clogging deposits when installed.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß durch gelochte oder geschlitzte Rohre gebildete Spülrohre vertikal in dem Füllgut eines Tropfkörpers eingebracht und mit Spülwasser beaufschlagbar sind. According to the invention, this object is achieved in that by perforated or slotted tubes formed flushing tubes vertically in the contents of a Trickling filter are introduced and can be acted upon with rinsing water.
Zweckmäßige Ausführungsformen für eine Vorrichtung gemäß der Erfindung sind Gegenstand der Ansprüche 2 und 3. Expedient embodiments for a device according to the invention are the subject of claims 2 and 3.
Eine in dieser Weise eingesetzte Vorrichtung zum Spülen eines Füllgutes, wie es herkömmlich in Tropfkörpern zur biologischen Abwasserbehandlung verwendet wird, stellt einen erheblichen Vorteil für den Betrieb derartiger Anlagen dar, da bisher eine wirksame Reinigung des gesamten Füllgutes nur nach dem Ausräumen und Waschen des Füllgutes außerhalb des Behälters möglich war. A device used in this way for rinsing a product, as it is conventionally used in trickling filters for biological wastewater treatment is, represents a significant advantage for the operation of such systems because So far, an effective cleaning of the entire product only after clearing and Washing of the contents outside the container was possible.
Die erfindungsgemäße Vorrichtung zum Spülen des Füllgutes kann die natürliche Hohlraumfreiheit des Füllgutes bereits nach einmaliger Anwendung weitgehend wieder herstellen und bleibt wegen des erhöhten Selbstreinigungsvermögens lange funktionstüchtig. The inventive device for rinsing the contents can natural void-free of the filling material already after a single application to a large extent restore and stay for a long time because of the increased self-cleaning capacity working.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt. The drawing shows an embodiment of the subject matter of the invention shown schematically.
