Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Reinigen von Abwässern.The invention relates to a device for cleaning waste water.
Damit Abwasserreinigungsanlagen einen hohen Wirkungsgrad besitzen benötigt man eine große Oberfläche für die Ansiedlung der Biomasse.So that wastewater treatment plants have a high efficiency you need one large surface area for the settlement of the biomass.
Es ist bekannt, daß in Abwasserreinigungsanlagen Trägermaterialien für die Ansiedlung von Biomasse verwendet werden.It is known that in waste water treatment plants carrier materials for the settlement of Biomass can be used.
Bei den Trägermaterialien ist ein breites Spektrum an zu verwendenden Materialien bekannt. Bsp.: Tonträgermaterialien. "Im Prinzip werden in der biologischen Wasseraufbereitung Inhaltsstoffe durch Mikroorga nismen (Biomasse) in Zellsubstanz und mineralische Endprodukte (CO2 und N2) umgewandelt. Die Biomasse bildet sich in der Biofiltration auf dem kugelförmigen Tonträgermaterial des Filterbettes oder in Form von suspendierten Flocken bei der Belebtschlammbiologie.A wide range of materials to be used is known for the carrier materials. Example: sound carrier materials. "In principle, in biological water treatment, ingredients are converted into cell substance and mineral end products (CO 2 and N 2 ) by microorganisms (biomass). The biomass is formed in the biofiltration on the spherical clay carrier material of the filter bed or in the form of suspended flakes in the Activated sludge biology.
Durch Optimierung der Milieubedingungen wird eine hohe Konzentration an aktiver Biomasse und damit eine günstige Raum-Zeit-Ausbeute erreicht."By optimizing the milieu conditions, a high concentration becomes more active Biomass and thus a favorable space-time yield achieved. "
Da die meisten Trägermaterialien aus natürlichen Rohstoffen bestehen sind diese, bis auf wenige Ausnahmen, mit einem hohen Energie- oder Kostenaufwand und mit einem Raubbau an der Natur verbunden.Since most carrier materials consist of natural raw materials, these are, except for few exceptions, with a high energy or cost expenditure and with overexploitation connected to nature.
Einen weiteren Nachteil stellen die regionale Begrenzung des Abbaus, dieser Rohstoffe und ihr hohes Eigengewicht dar, dies führt zu hohen Transportkosten.A further disadvantage is the regional limitation of the mining, these raw materials and their high weight, this leads to high transport costs.
Außerdem stellt die begrenzte Lebensdauer durch mechanische Belastung ebenso wie die komplizierte Transporttechnologie ein weiteres Problem dar.In addition, the limited life due to mechanical stress just like the complicated transportation technology is another problem.
Zu Komplikationen können auch unerwünschte Reaktionen mit chemischen Zusatzstoffen führen.Adverse reactions with chemical additives can also lead to complications to lead.
Tonträgermaterialien haben weiterhin den Nachteil, daß die Biomasse sich nicht nur an der Oberfläche bildet. Bei der Ansiedlung der Mikroorganismen im Trägermaterial kommt es zur Nahrungs- und Sauerstoffzehrung. Diese Auswirkungen sind unerwünscht.Sound carrier materials have the further disadvantage that the biomass does not only adhere to the Surface forms. When the microorganisms settle in the carrier material, Food and oxygen consumption. These effects are undesirable.
Die Aufgabe des Trägermaterials aus Kunststoff-Recycleabfällen besteht darin diese Nachteile möglichst kostengünstig zu beheben und die Ansiedlung von Biomasse auf gleiche Weise zu ermöglichen.The task of the carrier material made of recycled plastic waste is this To eliminate disadvantages as cost-effectively as possible and to settle biomass on the same Way to enable.
Durch die Nutzung nichtverwendbarer Materialien des Dualen Systems, wird der Abbau natürlicher Rohstoffe für diesen Zweck verhindert. By using non-usable materials of the dual system, the degradation natural raw materials prevented for this purpose.
Ausführungsbeispiele der Erfindung werden wie folgt beschrieben.Embodiments of the invention are described as follows.
Trägermaterialien der Abwasserreinigung für Festbettreaktoren, Belebtschlammbecken oder anderer Bioreaktoren, bestehen aus Kunststoffabfällen verschiedener Materialien, Form und beliebiger Korngröße des Dualen Systems mit der Aufgabe Biomasse an deren Oberfläche anzusiedeln.Carrier materials for wastewater treatment for fixed bed reactors, activated sludge tanks or other bioreactors, consist of plastic waste of different materials, shape and any grain size of the dual system with the task of biomass on its surface to settle.
Mit Hilfe von Abfällen werden Abwässer gereinigt. Waste water is cleaned with the help of waste.
Das Eigengewicht des Kunststoff-Recyclematerials ist bei gleichem Volumen geringer als bei bekannten Trägermaterialien.The weight of the recycled plastic material is lower than for the same volume known carrier materials.
Eine wesentliche Einsparung der Transportkosten wird durch das dichte Flächennetz des Dualen Systems gesichert.A substantial saving in transport costs is made possible by the dense network of the Dual systems secured.
Durch die guten hydraulischen Eigenschaften und durch das geringe Eigengewicht wird eine komplizierte Transporttechnologie vereinfacht.Due to the good hydraulic properties and the low weight complicated transportation technology simplified.
Der mechanische Abrieb und chemische Reaktionen sind unwesentlich.The mechanical abrasion and chemical reactions are immaterial.
Die Dichte des Recyclematerials ist kleiner als eins, dadurch ergibt sich eine isolierende Wirkung durch die der Wärmeverlust an der Oberfläche eingedämmt wird.The density of the recycled material is less than one, which results in an insulating one Effect by which the heat loss on the surface is contained.
Die Kunststoff-Recyclestoffe werden vom Dualen System wesentlich billiger angeboten als bisher verwendete Materialien.The dual system offers plastic recycled materials much cheaper than previously used materials.
Das Spülen bzw. das Reinigen des Trägermaterials ist mit einem geringerem Energie- und Zeitaufwand verbunden.The rinsing or cleaning of the carrier material is less Energy and time required.
