Abstract
Description
Die Erfindung betrifft einen Tropfkörper zur Reinigung von Abwässern mit Hilfe von Nitrifikation und Denitrifikation.The invention relates to a trickling filter for cleaning Sewage using nitrification and denitrification.
Unter Nitrifikation versteht man bekanntlich eine Oxydation des durch Zersetzung von stickstoffhaltigen biologischen Substanzen freiwerdenden Ammoniaks zu Nitrat mit Hilfe von aeroben bzw. nitrifizierenden Bakterien (Nitrifikanten).As is known, nitrification is an oxidation by the decomposition of nitrogenous biological Substances released ammonia to nitrate with the help of aerobic or nitrifying bacteria (nitrifying bacteria).
Dabei wird das im Abwasser enthalten NH4 bei Sauerstoff anreicherung in NO2 umgesetzt und dabei ein Nitrit gebildet, das durch weitere Oxydation in Nitrat umgewandelt wird. Nitrifikation tritt daher nur bei Sauerstoffüberschuß auf.The NH4 contained in the wastewater with oxygen enrichment converted into NO2 and a nitrite formed, which is converted to nitrate by further oxidation. Nitrification therefore only occurs when there is an excess of oxygen.
Unter Denitrifikation wird bekanntlich ein biologischer Prozeß verstanden, bei dem die durch Nitrifikation entstandenen Nitrate durch bestimmte Bakterien in Stickoxad oder freien Stickstoff umgewandelt werden, wobei jedoch Voraussetzung ist, daß Sauerstoffmangel herrscht, damit die Bakterien veranlaßt werden, den in der Nitratverbindung enthaltenen Sauerstoff aufzuspalten und dabei den Stickstoff freizusetzen.As is well known, denitrification becomes a biological one Process understood in which by nitrification Nitrates created by certain bacteria in Stickoxad or free nitrogen are converted, however The prerequisite is that there is a lack of oxygen so that the Bacteria are caused in the nitrate compound contained oxygen and split the nitrogen release.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Tropfkörper zur Reinigung von Abwasser zu schaffen, und diesen so auszubilden, daß die bei der Nitrifikation und Denitrifikation sich abspielenden biologischen Vorgänge optimal ausgenutzt werden können. The invention is based on the object Creating trickling filters for the purification of waste water, and to train this so that the nitrification and Denitrification of biological processes taking place can be optimally used.
Das wird erfindungsgemäß dadurch erreicht, daß der Tropfkörper aus mehreren Schichten zusammengesetzt ist, wobei jeweils eine Schicht aus einem Material besteht, welches Luft gut durchläßt, und darauffolgend eine Schicht aus einem Material, welches die Luft schlecht durchläßt, und daß diese Schichten wechselweise angeordnet sind.This is achieved in that the Trickling filter is composed of several layers, wherein one layer each consists of a material which is air lets well through, and then a layer of one Material that does not allow the air to pass, and that this Layers are arranged alternately.
Eine schlecht luftdurchlässige Schicht besteht dabei z. B. aus Lavaschlacke; hingegen besteht eine Schicht aus einem gut luftdurchlässigen Material, z. B. einem würfelförmigen Kunststoff-Füllmaterial mit ausreichender Druckfestigkeit.A poorly air-permeable layer consists, for. B. from Lava slag; on the other hand, a layer consists of a good breathable material, e.g. B. a cube-shaped Plastic filling material with sufficient pressure resistance.
Wird nun Abwasser auf diesen Tropfkörper gesprüht, dann bilden sich in den Bereichen, in denen eine Sauerstoff anreicherung wegen der besseren Luftdurchlässigkeit möglich ist, mit Hilfe der Bakterien Nitrate. In der nachfolgenden Schicht, in der wegen der schlechten Luftdurchlässigkeit ein Sauerstoffmangel herrscht, wird das Nitrat mit Hilfe der Bakterien in freien Stickstoff umgesetzt.If wastewater is now sprayed onto this trickling filter, then form in areas where there is oxygen Enrichment possible due to the better air permeability is nitrates with the help of bacteria. In the following Layer in which due to poor air permeability If there is a lack of oxygen, the nitrate is removed with the help of Bacteria converted into free nitrogen.
Damit die Luft nicht gleichmäßig durch den gesamten Tropfkörper strömt, sind im Tropfkörper Luftdurchgangszonen vorgesehen. Bei der einen Ausführungsform ist dabei die Luftdurchgangszone in den schlecht luftdurchlässigen Schichten eingebaut, die den Zweck haben, bevorzugte Luftwege zu schaffen, damit sich an der gewünschten Stelle (Lavaschlacke) sich Sauerstoffmangel einstellen kann. Den gleichen Zweck erreicht man, wenn man die gut luftdurchlässige Schicht selbst belüftet und dadurch als Luftdurchgangszone ausbildet, auch hier entsteht der gewünschte Sauerstoffmangel in der schlecht luftdurchlässigen Schicht.So that the air is not evenly through the whole The trickling filter flows, there are air passage zones in the trickling filter intended. In one embodiment, the Air passage zone in the poorly air-permeable Layers built in, which have the purpose of preferred airways to create so that it is in the desired location (Lava slag) oxygen deficiency can occur. The same purpose can be achieved if you do the well air-permeable layer self-ventilated and therefore as Air passage zone forms here, too desired lack of oxygen in the poorly air-permeable Layer.
In der Zeichnung ist schematisch ein solcher Tropfkörper dargestellt.Such a trickling filter is shown schematically in the drawing shown.
Fig. 1 zeigt den Tropfkörper in der einen Ausführungsform; Fig. 1 shows the trickling filter in one embodiment;
Fig. 2 zeigt den Tropfkörper in der anderen Ausführungsform. Fig. 2 shows the trickling filter in the other embodiment.
Mit 2 sind dabei jeweils die Schichten bezeichnet, die gut durchlässig ausgebildet sind, während mit 1 die Schichten bezeichnet sind, die schlecht luftdurchlässig ausgebildet sind. Dabei handelt es sich bei der Schicht, die mit 1 bezeichnet ist, um Lavaschlacke, hingegen bei der Schicht, die mit 2 bezeichnet ist, um ein würfelförmiges Kunststoff- Füllmaterial mit ausreichender Druckfestigkeit. 2 each denotes the layers that are well permeable, while 1 denotes the layers that are poorly air permeable. The layer that is labeled 1 is lava slag, whereas the layer that is labeled 2 is a cube-shaped plastic filling material with sufficient compressive strength.
Damit der erwünschte Sauerstoffmangel in der schlecht luftdurchlässigen Schicht 1 bei der Luftdurchströmung gemäß der Pfeile 6 entsteht, sind in den schlecht luftdurchlässigen Schichten 1 Luftdurchgangszonen (Kanäle 3) eingebaut, die die gut luftdurchlässigen Schichten 2 verbinden. Die Ausführungs form in Fig. 2 unterscheidet sich von der in Fig. 1 dadurch, daß die gut luftdurchlässigen Schichten 2 in der Längsachse der Schicht durchströmt werden, um den Sauerstoffmangel in der Schicht 1 zu ermöglichen. So that the desired lack of oxygen in the poorly air-permeable layer 1 arises in the air flow according to the arrows 6 , air passage zones (channels 3 ) are installed in the poorly air-permeable layers 1 , which connect the well air-permeable layers 2 . The embodiment in Fig. 2 differs from that in Fig. 1 in that the air-permeable layers 2 are flowed through in the longitudinal axis of the layer in order to enable the lack of oxygen in layer 1 .
Der Zulauf erfolgt bei 4, so daß das Abwasser zunächst in die Schicht 2 gelangt, die gut luftdurchlässig ausgebildet ist, also an Sauerstoff reich ist, so daß dort mit Hilfe der Bakterien eine Nitratbildung stattfindet.The inflow takes place at 4 , so that the waste water first reaches layer 2 , which is well permeable to air, ie is rich in oxygen, so that nitrate formation takes place there with the help of the bacteria.
Dieses nitrathaltige Abwasser gelangt dann in die Schicht 1, die schlecht luftdurchlässig ausgebildet ist, wo also Sauerstoffmangel herrscht, und wo die Bakterien Veranlassung haben, infolge des Sauerstoffmangels das Nitrat aufzuspalten und dabei den Sauerstoff zu verbrauchen und den freien Stickstoff abzugeben.This nitrate-containing wastewater then passes into layer 1 , which is poorly air-permeable, where there is a lack of oxygen, and where the bacteria have reason to break down the nitrate due to the lack of oxygen and thereby consume the oxygen and release the free nitrogen.
Da das Abwasser durch mehrere wechselweise angeordnete Schichten dieser Art läuft, erfolgt bei entsprechender Bemessung eine völlige Reinigung des Abwassers von Nitraten mit Hilfe der geschilderten Nitrifikation- bzw. Denitrifikationsvorgänge.Because the wastewater by several alternately arranged Layers of this type runs, with appropriate Dimensioning a complete purification of the nitrate wastewater with the help of the nitrification or Denitrification processes.
Der Abgang des gereinigten Abwasser erfolgt bei 5.The cleaned waste water is discharged at 5 .
