Description

Die Erfindung betrifft die Verwendung von Zeolith-Ringen mit einer zentrischen Bohrung, einer Höhe und Breite zwischen 200 mm und 20 mm bei einer Wandstärke von min­ destens 5 mm als Tropfkörper oder Füllmaterial in Reak­ toren oder Kolonnen.The invention relates to the use of zeolite rings with a central bore, height and width between 200 mm and 20 mm with a wall thickness of min at least 5 mm as trickling filter or filling material in reak gates or columns.

Ammonium-Ionen (NH4+) oder Ammoniak (NH3-) werden von Roh- und/oder Abwässern gegenwärtig durch Ionenaustausch oder durch Stripping oder mit Hilfe von biologischen Verfahren entfernt. Je nachdem, wie hoch die Ammonium/ Ammoniak-Konzentration ist, kann man von diesen drei Möglichkeiten Gebrauch machen. Die Ammonium-Ionen werden mit den Kationenaustauschern ökonomisch nur in dem Falle entfernt, wenn die Konzentration im Wasser relativ klein ist. Größere Mengen von Ammonium werden durch mikrobiel­ le Vorgänge, d. h. durch aerobe und anaerobe Schritte - erst zu NO3 oxidiert und dann zu N2 reduziert - elimi­ niert. Es sind nach diesen Prinzipien ausgereifte Tech­ nologien, die überall in der Welt in den verschiedensten Wasservorbehandlungen und Kläranlagen immer mehr verwen­ det werden. Jedes der genannten Verfahren hat, vergli­ chen mit den anderen, bestimmte Vor- und Nachteile. Wenn mit Kationenaustauschern gearbeitet wird, muß man sich zwangsläufig mit der Regenerierung des Ionenaustauschers beschäftigen, abgesehen davon, daß die Ionenaustauscher sehr teuer sind. Wenn NH4+ auf biologischem Wege ent­ fernt wird, sind mehrere Schritte erforderlich, um zum Endziel zu gelangen.Ammonium ions (NH4 +) or ammonia (NH3-) are from Raw and / or waste water currently through ion exchange or by stripping or with the help of biological Procedure removed. Depending on how high the ammonium / Ammonia concentration is one of these three Make use of opportunities. The ammonium ions are economically with the cation exchangers only in this case removed when the concentration in the water is relatively small is. Larger amounts of ammonium are microbial operations, d. H. through aerobic and anaerobic steps - first oxidized to NO3 and then reduced to N2 - elimi kidney. They are mature tech based on these principles technologies that are all over the world in the most diverse Use water pretreatment and sewage treatment plants more and more be det. Each of the methods mentioned has, see with the others, certain advantages and disadvantages. If you have to work with cation exchangers inevitably with the regeneration of the ion exchanger deal, besides that the ion exchanger are very expensive. If NH4 + occurs biologically is removed, several steps are required to get to the  Final destination.

Der vorliegenden Erfindung liegt daher die Aufgabe zu­ grunde, NH4+-Ionen quasi direkt, in einem Schritt aus dem Wasser oder aus wäßrigen Lösungen zu entfernen.The present invention is therefore based on the object reasons, NH4 + ions quasi directly, in one step to remove the water or from aqueous solutions.

Zur Lösung der gestellten Aufgabe wird die Verwendung von Zeolith-Ringen mit einer zentrischen Bohrung, einer Höhe und Breite zwischen 200 mm und 20 mm bei einer Wandstärke von mindestens 5 mm als Tropfkörper oder Füllmaterial in Reaktoren oder Kolonnen zum biologischen Entfernen von Ammonium/Ammoniak aus Wasser, insbesondere Trink-, Brauch- oder Abwasser, vorgeschlagen.Use is used to solve the task of zeolite rings with a central bore, one Height and width between 200 mm and 20 mm at one Wall thickness of at least 5 mm as trickling filter or Filling material in reactors or columns for biological Removing ammonium / ammonia from water, in particular Drinking, industrial or waste water, proposed.

Es wurden zwar bisher schon Tropfkörper aus Basalttuff (Lavagestein), PVC, Polystyrol, Papier mit Kunstharz im­ prägniert, usw. verwendet, hierbei konnte jedoch der Ef­ fekt der direkten Entfernung von Ammonium/Ammoniak aus dem Wasser nicht beobachtet werden.So far there have been trickling filters made of basalt tuff (Lava stone), PVC, polystyrene, paper with synthetic resin in the impregnated, etc. used, however, the Ef effect of the direct removal of ammonium / ammonia not be observed in the water.

Die Zeolith-Ringe werden vor ihrer Verwendung mit C1 bis C6-Carbonsäuren und/oder Hydroxycarbonsäuren wie z. B. Ameisensäure, Essigsäure, Milch­ säure, Capronsäure usw., behandelt.The zeolite rings are pre-used with C1 to C6 carboxylic acids and / or hydroxy carboxylic acids such as B. formic acid, acetic acid, milk acid, caproic acid, etc. treated.

Anhand der Zeichnung soll am Beispiel eines ZeoIith- Ringes die erfindungsgemäße Verwendung derartiger Ringe dargestellt werden. Using the drawing, using the example of a ZeoIith Ring the use of such rings according to the invention being represented.  

Die Zeichnung zeigt eine perspektivische Darstellung eines aus Zeolith hergestellten Ringes.The drawing shows a perspective view of a ring made of zeolite.

Wie sich aus der Zeichnung ergibt, besteht der Zeolith- Ring aus einem zylindrischen Formkörper 1 aus künstli­ chem und/oder natürlichem Zeolithmaterial, welcher eine zentrische Bohrung 2 aufweist. Die Wanddicke d des Form­ körpers beträgt mindestens 5 mm.As can be seen from the drawing, the zeolite ring consists of a cylindrical molded body 1 made of artificial and / or natural zeolite material which has a central bore 2 . The wall thickness d of the molded body is at least 5 mm.

Die Höhe h des Formkörpers kann zwischen 200 mm und 20 mm betragen. Die Breite b kann ebenfalls zwischen 200 mm und 20 mm betragen.The height h of the molded body can be between 200 mm and 20 mm. The width b can also be between 200 mm and 20 mm.

Die so hergestellten Zeolith-Ringe werden als Füll­ material in beliebiger Anordnung geschichtet in einen Reaktor oder in eine Kolonne gegeben. Diese Anordnung wird von dem zu behandelnden Wasser durchflossen. Nach dem Kontaktieren des Ammoniak enthaltenden Wassers mit den Zeolith-Ringen gemäß der Erfindung entstehen nach kürzester Zeit Mischbiozönosen durch Ablagerung der Mikroorganismen. Dabei entstehen am Ring zwei Schichten, nämlich an der Außenseite eine aerobe Schicht mit aus­ reichender Sauerstoffzufuhr mit Nitrobakterien und Nitrosomonas. Im Ringmaterial selbst entsteht eine an­ aerobe Schicht mit unzureichender oder keiner Sauer­ stoffzufuhr mit Pseudomonas und Benitrobacillus. Die NH4-Ionen werden in dem Zeolith mit Hilfe von Kationen­ austausch festgehalten, die dann durch aerobe und/oder anaerobe Abbauvorgänge umgesetzt und als Stickstoff ent­ fernt werden.The zeolite rings produced in this way are used as fillers material in any arrangement layered in one Reactor or placed in a column. This arrangement is flowed through by the water to be treated. To contacting the water containing ammonia the zeolite rings according to the invention arise after mixed biocenoses by deposition of the Microorganisms. This creates two layers on the ring, namely on the outside with an aerobic layer sufficient oxygen supply with nitrobacteria and Nitrosomonas. One forms in the ring material itself aerobic layer with insufficient or no acid feed with Pseudomonas and Benitrobacillus. The NH4 ions are in the zeolite with the help of cations exchange held by aerobic and / or Anaerobic degradation processes implemented and ent as nitrogen be removed.

Die Zeolith-Ringe können aus verschiedenen Zeolithen, insbesondere aus natürlichen Zeolithen, durch Kleben und Pressen hergestellt werden. Die Korngröße des Ausgangs­ materials liegt unter 5 mm, und die Wanddicke d jedes Ringes muß mindestens 5 mm betragen. Die Höhe h liegt zwischen 200 mm und 20 mm, ebenso liegt die Breite b zwischen 200 mm und 20 mm.The zeolite rings can be made from different zeolites, especially from natural zeolites, by gluing and Presses are made. The grain size of the output materials is less than 5 mm, and the wall thickness d each Ring must be at least 5 mm. The height h is  between 200 mm and 20 mm, likewise the width b between 200 mm and 20 mm.

Die Zeolith-Ringe weisen eine viel größere Oberfläche als die bisher verwendeten, oben erwähnten Tropfkörper auf. Ein wesentlicher Unterschied zu den bekannten Tropfkörpern besteht noch darin, daß die Zeolith-Ringe kontinuierlich pH-stabilisierend wirken und somit die Voraussetzungen für den biologischen Abbau von NH4+ schaffen.The zeolite rings have a much larger surface than the previously used trickling filters used above on. A major difference to the known Trickling filters is still that the zeolite rings continuously stabilize the pH and thus the Prerequisites for the biodegradation of NH4 + create.
