Description
Vorrichtung zum mechanischen und biologischen Klären von Abwässern Die Erfmdung bezieht sich auf eine Vorrichtung zum mechanischen und biologischen Klären von Ab- wässern mit mehreren hintereinandergeschalteten Klärbecken, in denen mindestens ein mechanisch wirkendes Filtermaterial und mindestens in einem Klärbecken eine Hydrokultur hochwüchsiger Wasserpflanzen vorgesehen sind und die mit überströmbaren und unterströmbaren quer zur Strömungsrichtung angeordneten Begrenzungswänden versehen sind.A device for mechanical and biological clarification of sewage The Erfmdung relates to a device for mechanical and biological clarifying waste water having a plurality of series-connected clarification basin, in which at least one mechanical filter material, and a hydroponic tall-growing aquatic plants are provided in at least one clarifier and with Overflowable and underflowable boundary walls arranged transversely to the direction of flow are provided.
Bei einer bekannten Vorrichtung dieser Art sind mehrere Klärbecken dieser Art derart unmittelbar hintereinandergeschaltet, wobei das eine Klärbecken zulaufseitig mit einer überströmbaren Begrenzungswand und ablaufseitig mit einer unterströmbaren Begrenzungswand versehen ist, die ablaufseitige unterströmbare Begrenzungswand dieses Klärbeckens gleichzeitig die zulaufseitige Begrenzungswand des folgenden Klärbeckens bildet und dieses ablaufseitig mit einer überströmbaren Begrenzungswand versehen ist. Diese Anordnung der Klärbecken mit den zugehörigen Begrenzungswänden hat insbesondere den Nachteil, daß jeweils das eine Klärbecken von oben nach unten und das folgende Klärbecken von unten nach oben durchströmt werden muß. Dadurch ergibt sich ein hoher Durchströmwiderstand für zwei derart hintereinandergeschaltete Klärbecken, der besonders bei einer Hintereinanderschaltung einer größeren Anzahl derartiger Klärbecken zu untragbaren Strömungsverhältnissen führt. Außerdem ist die Rückspülung der von unten nach oben durchströmten Klärbecken von den durch das mechanisch wirkende Filtermaterial festgehaltenen Fremdstoffen außerordentlich erschwert, weil diese Fremdstoffe durch die gesamte darüberliegende Schicht des Filtermaterials hindurch nach oben ausgetragen werden müssen, während. sich in einem von oben nach unten durchströmten Klärbecken die ausgefilterten Fremdstoffe beim Rückspülen leicht nach oben austragen lassen.In a known device of this type, there are several clarifiers of this type connected directly one behind the other, with the one clarifier On the inlet side with a boundary wall that can be flowed over and on the outlet side with a is provided underflow boundary wall, the discharge-side underflow boundary wall this clarifier at the same time the inlet-side boundary wall of the following Clarifier forms and this on the outlet side with an overflow boundary wall is provided. This arrangement of the clarifier with the associated boundary walls has the particular disadvantage that in each case a clarifier from top to bottom and the following clarifier must be flowed through from bottom to top. Through this this results in a high flow resistance for two connected in series in this way Clarifier, which is particularly important when a larger number is connected in series such clarifier leads to intolerable flow conditions. Also is the backwashing of the clarification basins through which the water flows from bottom to top from the mechanically acting filter material makes it extremely difficult for trapped foreign matter, because these foreign substances pass through the entire overlying layer of the filter material must be discharged through upwards while. down in a top down At the bottom, the clarifier basins easily flowed through the filtered out foreign matter during backwashing can be discharged upwards.
Die Erfindung bezweckt, die Nachteile der bekannten Vorrichtung zu vermeiden, wobei insbesondere der Strömungswiderstand verringert und das Rückspülen erleichtert werden sollen. Die Erfindung besteht bei einer Vorrichtung der eingangs genannten Art darin, daß jedes Klärbecken zulaufseitig mit einer überströmbaren Begrenzungswand und ablaufseitig mit einer unterströmbaren Begrenzungswand mit sich zum Boden erstreckendem Haltegitter versehen ist und jedem Klärbecken ein von Filtermaterial und Wasserpflanzen freier Aufströmraum nachgeschaltet ist, dessen Breite klein ist im Vergleich zur Länge des Klärbeckens.The invention aims to address the disadvantages of the known device avoid, in particular reducing the flow resistance and backwashing should be facilitated. The invention consists in a device of the introduction mentioned type in that each clarifier on the inlet side with an overflow Boundary wall and on the outlet side with a boundary wall that can flow under it is provided extending to the bottom retaining grid and each clarifier a filter material and aquatic plants free upflow space is connected downstream, the width of which is small compared to the length of the clarifier.
Dadurch ergeben sich innerhalb der Vorrichtung nur Klärbecken, die von oben nach unten durchströmt werden und daher leicht rückgespült werden können. Durch das Haltegitter wird das Filtermaterial von dem Aufströmraum ferngehalten, so daß sich in diesem, der auch frei von Wasserpflanzen ist, kein merklicher Strömungswiderstand ergibt. Dies ermöglicht die Hintereinanderschaltung zahlreicher Klärbecken unter Einhaltung eines tragbaren gesamten Durchströmwiderstandes.This results in only clarifiers within the device can be flowed through from top to bottom and can therefore easily be backwashed. The filter material is kept away from the upflow space by the retaining grille, so that in this one, which is also free of aquatic plants, there is no noticeable flow resistance results. This enables numerous clarifiers to be connected in series Compliance with a portable total flow resistance.
Als Filtermaterial kommt bei der Vorrichtung nach der Erfindung beispielsweise Lavaschlacke und gebrochener, gewaschener Kies in Betracht. Diese beiden Filterinaterialien können auch derart kombiniert verwendet werden, daß über einer Schicht Lavaschlacke eine Schicht gebrochener, gewaschener Kies angeordnet ist. Das Filtermaterial dient gleichzeitig als Pflanzgrundlage für die das biologische Klären bewirkenden Wasserpflanzen, z. B. Flechtbinsen, Schilfrohr oder Pfefferminze.In the device according to the invention, for example, is used as the filter material Consider lava slag and broken, washed gravel. These two filter materials can also be used in combination in such a way that lava slag over a layer a layer of broken, washed gravel is arranged. The filter material is used at the same time as a plant base for the aquatic plants that cause biological clarification, z. B. rushes, reeds or peppermint.
Zum Belüften der Klärbecken und für das Rückspülen können bei der Vorrichtung nach der Erfindung in an sich bekannter Weise über dem Boden der Klärbecken Rohre mit öffnungen angeordnet sein, die mit Druckluft zum Belüften und Rückspülen und gegebenenfalls auch mit Druckwasser zum Rückspülen beaufschlagt werden können.To aerate the clarifier and for backwashing, the Device according to the invention in a manner known per se above the bottom of the clarifier Pipes can be arranged with openings that are supplied with compressed air for venting and backwashing and, if necessary, can also be subjected to pressurized water for backwashing.
