Abstract
Es ist die Aufgabe der Erfindung mit Hilfe von mindestens zwei unterschiedlichen Trägerelementen zur Immobilisierung von Mikroorganismen Milieubedingungen zu schaffen, die dazu führen, dass das Verfahrensziel der Optimierung des Biomassezuwachses im System gezielt beeinflusst werden kann. Dies gelingt durch gezielten Einsatz von mindestens zwei unterschiedlichen Trägerelementen auf denen sich unterschiedliche Biofilme dauerhaft etablieren können, die lange Standzeiten auch in turbulenten aeroben und/oder anaeroben Flüssigkeitsströmen aufweisen und die ein an die Aufgabenstellung optimiertes Verhältnis von Volumen zu Oberfläche und von Oberfläche zu Porenvolumen haben. Dieses Verfahren war bisher nicht bekannt und ist geeignet entsprechend an die jeweilige Aufgabenstellung angepasst eine minimale oder maximale Biomassemenge (Überschussschlamm) sicherzustellen. Anwendungsgebiet: Das Anwendungsgebiet betrifft die Wasser- und Abwasseraufbereitung.It is the object of the invention with the help of at least two different carrier elements for the immobilization of microorganisms to create environmental conditions which lead to the fact that the process objective of optimizing the biomass increase in the system can be influenced in a targeted manner. This is achieved by targeted use of at least two different support elements on which different biofilms can permanently establish long standing times even in turbulent aerobic and / or anaerobic liquid streams and have an optimized to the task ratio of volume to surface and surface to pore volume , This method was previously unknown and is suitable to ensure a minimum or maximum amount of biomass (surplus sludge) adapted to the respective task. Field of application: The field of application concerns water and wastewater treatment.
Description
Die Erfindung betrifft ein Verfahren zur biologischen Reinigung von Wasser, beispielsweise Abwasser, wobei mindestens zwei unterschiedliche Trägermaterialien benutzt werden.The The invention relates to a method for the biological purification of Water, such as wastewater, wherein at least two different Carrier materials are used.
Es
ist bekannt, feste Körper, insbesondere Hohlkörpern,
zur biologischen Reinigung von Abwasser, die in einem Reaktor im
Schwebezustand und in ständiger Bewegung gehalten werden
und an denen ein bakterieller Bewuchs haftet, zu verwenden (
Geeignete Trägermaterialien wurden in der in der Folge beschrieben.suitable Support materials were described in the following.
Ein
solches Trägermedium ist beispielsweise aus der offen gelegten
In
dem Patent
Es wird weiter angenommen, dass die Filterelemente, um einander in einem oder mehreren Bereichen abstützen zu können, während gleichzeitig ein ausreichend großer Abstand zwischen den Elementen vorhanden sein muss, um es dem Filter zu erlauben, effektiv zu wirken, eine so große räumliche Erstreckung haben, dass, ein dicker Biofilm gebildet wird, wo unkontrollierte aerobische und anaerobische Reaktionen stattfinden können. Bei diesem Typ der bekannten Trägerelemente wird der Biofilm in Durchgängen und Räumen etabliert welche gegen Kollisionen mit der Oberfläche anderer Trägerelemente geschützt ist. Um ein Zuwachsen dieser Räume und Durchgänge zu verhindern und die notwendige Substratzufuhr zu gewährleisten, darf ein kritischer Abstand zwischen den Oberflächen nicht unterschritten werden. Dieser kritische Abstand bedingt die Ausbildung eines komplexen Biofilms der u. a. aus Einzellern (z. B. Bakterien/Pilze) und Mehrzellern (z. B. Ciliaten) zusammengesetzt ist. Bakterien und Bakterienfresser sind in diesen Biofilmen miteinander vergesellschaftet und nicht zu trennen.It is further assumed that the filter elements to each other in one or more areas to support, while at the same time a sufficiently large distance between the elements to allow the filter to to be effective, such a large spatial extent have that, a thick biofilm is formed where uncontrolled aerobic and anaerobic reactions can take place. In this type of known carrier elements, the biofilm in passages and rooms established which against collisions protected with the surface of other support elements is. To grow together these spaces and passages prevent and ensure the necessary substrate supply, Do not allow a critical distance between the surfaces be fallen below. This critical distance requires training a complex biofilm of u. a. from unicellular organisms (eg bacteria / fungi) and multicellular (e.g., ciliate). bacteria and bacterial eaters are socialized in these biofilms and not separate.

dem Patent
Aufgrund der angestrebten großen Oberfläche haben die Poren einen Öffnungsspalt von kleiner 1 mm und eine Tiefe von kleiner 1 mm. Mit mikroskopischen Untersuchungsmethoden wurde festgestellt, dass sich auf diesen Oberflächen nur Bakterien und Pilze ansiedeln können. Höhere Organismen, beispielsweise Bakterienfresser, können sich aufgrund der Milieubedingungen in diesem Biofilm nicht etablieren, da diese Organismen größer sind als die angebotenen Hohlräume und/oder die Scherkräfte im System dies verhindern. Damit ist eine gezielte Beeinflussung und Optimierung der Zusammensetzung der aktiven Biocoenose (Einzeller und/oder Mehrzeller) für den gewünschten Anwendungsfall nicht möglich.by virtue of the aspired large surface have the pores an opening gap of less than 1 mm and a depth of less than 1 mm. Using microscopic examination methods it was found that settle on these surfaces only bacteria and fungi can. Higher organisms, such as bacterial predators, may be due to the environmental conditions in this biofilm do not establish because these organisms are larger as the offered cavities and / or the shear forces prevent this in the system. This is a targeted influence and optimization of the composition of active biocoenosis (protozoan and / or Mehrzeller) for the desired application not possible.
Es ist die Aufgabe der Erfindung mit Hilfe von mindestens zwei unterschiedlichen Trägermaterialien in einem Reaktor die Milieubedingungen so einzustellen, dass entsprechend der Aufgabenstellung ein Minimum oder Maximum an mikrobiellem Zuwachs erzielt wird. Durch den Einsatz von mindestens zwei verschiedenen Trägerelementen, die sich in ihrer Form und Größe unterscheiden und damit auch unterschiedliche mechanische Eigenschaften im Wasser aufweisen, gelingt es die Milieubedingungen für Bakterien/Pilze bzw. für Bakterienfresser in der Art festzulegen, dass die bevorzugte Organismengruppe im System optimale Wachstumsbedingungen vorfindet und die gewünschten Soffwechselleistungen erbringen kann.It is the object of the invention with the help of at least two different Carrier materials in a reactor, the environmental conditions adjust so that according to the task a minimum or maximum microbial growth is achieved. Because of the engagement of at least two different carrier elements, the differ in their shape and size and thus also different mechanical properties in the water have succeeded, the environmental conditions for bacteria / fungi or for bacterial eaters in the way specify that the preferred group of organisms in the system optimal growth conditions finds and deliver the desired Soffwechselistungen can.
Ein
Ausführungsbeispiel der Erfindung ist in der Zeichnung
dargestellt und wird im Folgenden näher beschrieben. Die
Durch den Einsatz unterschiedlicher Mengen von Trägerelement 1 und 2 kann die Menge an Bakterien bzw. Bakterienfressern im System eingestellt werden. Dadurch gelingt es die anfallende Überschussbiomasse, entsprechend dem Verfahrensziel, zu minimieren oder zu maximieren, bzw. die Stoffwechselleistungen der jeweiligen Trophieebene zu optimieren.By the use of different amounts of carrier element 1 and 2 can be the amount of bacteria or bacterial predators in the system be set. As a result, the resulting surplus biomass, according to the process objective of minimizing or maximizing or to optimize the metabolic performance of the respective trophic level.
