Description
Die Erfindung bezieht sich auf ein Trägermaterial kombiniert mit einer biologisch abbaubaren Kohlenstoffquelle und Verfahren zur Anwendung mit den weiteren Merkmalen nach dem Oberbegriff des Patentanspruches 1. Trägermaterialien werden in der Wasseraufbereitung angewendet um Mikroorganismen auf Oberflächen in Biofilmen zu immobilisieren. Anwendungsbereiche sind die Nitrifikation, die Denitrifikation und biologischer Abbau verschiedener unerwünschter Substanzen. Kohlenstoffquellen sind dazu geeignet, das Wachstum von Mikroorganismen zu fördern.The invention relates to a carrier material combined with a biodegradable carbon source and method of use with the further features according to the preamble of
Das Trägermaterial mit biologisch abbaubarer Kohlenstoffquelle dient dazu, die Nitratelimination mit Hilfe von Mikroorganismen in der Wasseraufbereitung zu verbessern.The carrier material with biodegradable carbon source serves to improve the nitrate removal with the help of microorganisms in the water treatment.
Stand der TechnikState of the art
Die heterotrophe Denitrifikation ist ein Verfahren, um Nitrat und weitere oxidierte Stickstoffverbindungen durch Mikroorganismen unter reduzierenden Bedingungen aus Wasser zu entfernen. Dazu sind u.U. zusätzliche organische Kohlenstoffquellen erforderlich. Üblicherweise werden lösliche Substrate wie Essigsäure, Methanol oder Ethanol zu dosiert (z.B. Menasveta et al., 2001, Van Rijn et al., 2006). Ihre Zugabe aber birgt die Gefahr der Fehldosierung. Bei Unterdosierung der C-Quelle ist keine vollständige Nitratelimination gewährleistet und Nitrit kann als Zwischenprodukt auftreten. Eine Überdosierung ist nicht nur unwirtschaftlich, sondern geht auch mit einer höheren Sauerstoffzehrung bei dem nachfolgenden aeroben Abbau einher. Zudem können anaerobe Prozesse begünstigt werden, was ggf. zur Bildung von giftigem H2S führt.Heterotrophic denitrification is a process for removing nitrate and other oxidized nitrogen compounds from water by microorganisms under reducing conditions. This may require additional organic carbon sources. Usually, soluble substrates such as acetic acid, methanol or ethanol are metered (eg Menasveta et al., 2001, Van Rijn et al., 2006). Their addition, however, carries the risk of misdosing. Underdosing of the C source does not ensure complete nitrate elimination and nitrite may occur as an intermediate. An overdose is not only uneconomical, but is also associated with a higher oxygen depletion in the subsequent aerobic degradation. In addition, anaerobic processes can be favored, possibly leading to the formation of toxic H 2 S.
Die Ansprüche beschreiben nur eine Anwendung für die Boden-Sanierung, nicht jedoch die Anwendung in wässrigen Milieus wie etwa speziell in der Aquakultur oder Wasseraufbereitung. Dieses Patent gibt keinen Hinweis darauf, dass Trägermaterialien eingesetzt werden.The claims describe only one application for soil remediation, but not the application in aqueous environments such as especially in aquaculture or water treatment. This patent gives no indication that support materials are used.
Aufgabenstellungtask
Aufgabe der Erfindung ist es, ein Trägermaterial kombiniert mit einer biologisch abbaubaren Kohlenstoffquelle und Verfahren zur Anwendung zur Verfügung zu stellen, das einfach in der Anwendung ist, insbesondere keine aufwendige Regelungstechnik erfordert, weil es ein sich selbstregulierendes biologisches System ist und kostengünstig im Betrieb einsetzbar ist.The object of the invention is to provide a carrier material combined with a biodegradable carbon source and method of use available, which is easy to use, in particular requires no complex control technology, because it is a self-regulating biological system and can be used inexpensively in operation ,
Es sollen deshalb Festsubstrate als Kohlenstoffquelle eingesetzt werden, die keine solche aufwendige Technik erforderlich machen. Festsubstrate dienen gleichzeitig als Aufwuchsfläche für die Mikroorganismen und als Kohlenstoffquelle für die Denitrifikation. Auf eine Zudosierung löslicher Kohlenstoffquellen kann verzichtet werden.It should therefore be used as a carbon source solid substrates that do not require such a complex technique. Solid substrates simultaneously serve as a growth area for the microorganisms and as a carbon source for denitrification. On a dosage of soluble carbon sources can be dispensed with.
Wird das Trägermaterial kombiniert mit einer biologisch abbaubaren Kohlenstoffquelle im Bereich von Trinkwasser eingesetzt, ist der Vorteil auch darin zu sehen, dass Fette, Fettsäuren, gesättigten Fettsäuren oder fettähnliche Substanzen - im Folgenden als „Fett“ bezeichnet - als Kohlenstoffquelle verwendet wird. Fett wird als Lebensmittel eingesetzt und ist insoweit unbedenklich.When the carrier material combined with a biodegradable carbon source in the drinking water sector is used, the advantage is also that fats, fatty acids, saturated fatty acids or fat-like substances - hereinafter referred to as "fat" - are used as the carbon source. Fat is used as a food and is safe in this respect.
Fette als Festsubstrate sind im Vergleich zu alternativ einsetzbaren biologisch abbaubaren Polymeren relativ kostengünstig.Fats as solid substrates are relatively inexpensive compared to alternatively usable biodegradable polymers.
Fette können aber auf Grund ihrer Eigenschaften wie Sprödigkeit und geringer Abriebfestigkeit nicht direkt für diesen Zweck eingesetzt werden.Due to their properties such as brittleness and low abrasion resistance, fats can not be used directly for this purpose.
Die technische Herausforderung ist es, ein Trägermaterial zur Verfügung zu stellen, mit dem sich Fett als biologisch abbaubare Kohlenstoffquelle in der Wasseraufbereitung einsetzen lässt. Eine Aufgabe des Trägermaterials ist deshalb, den Schutz der Fette vor Abrieb und Zerbrechen zur Verfügung zu stellen. Damit soll das Austragen von Fettpartikeln vermindert werden, was ansonsten zu erheblichen Problemen bei den anschließenden Verfahrensschritten führen kann. Gleichzeitig ist es Ziel, die Dichte des kombinierten Trägermaterials mit Kohlenstoffquelle je nach den verfahrenstechnischen Anforderungen beeinflussen zu können.The technical challenge is to provide a carrier material that can be used as a biodegradable source of carbon in water treatment. An object of the carrier material is therefore to provide the protection of the fats from abrasion and breakage. This is intended to reduce the discharge of grease particles, which can otherwise lead to considerable problems in the subsequent process steps. At the same time, the goal is to increase the density of the combined carrier material Depending on the process requirements to influence carbon source.
Die Aufgabe ist erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen des erfindungsgemäßen Trägermaterials kombiniert mit einer biologisch abbaubaren Kohlenstoffquelle sind in den weiteren Ansprüchen angegeben.The object is achieved by the features of
