Abstract

Contaminated media, partic. surface water and soils, are cleaned, e.g. of hydrocarbons etc., by an absorption medium which is mfd. by a method in which a substrate material is produced by high-speed grinding of material from a compact piece using a grinding roller. The substrate particles that result are combined with at least one oxidic additive reducing adhesion and an organic, closed-pore parting material is incorporated in the surfaces of the substrate particles. The parting medium is pref. cork powder. A pref. substrate is formed by rubber particles.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Aufnahmesubstrats nach dem Oberbegriff des Hauptanspru­ ches.The invention relates to a method for producing a Receiving substrate according to the preamble of the main claim ches.

Aufnahmesubstrate werden zur Reinigung verschmutzter Me­ dien, speziell zur Reinigung von Oberflächengewässern und Böden verwandt. Hierbei handelt es sich vorzugsweise um ein Adsorptions-, Koagulations- und/oder Flockungsmittel für flüssige Kohlenwasserstoffe der Gruppen Paraffine, Olefine, Naphthene und Aromaten und deren Modifikanten. Die Anwendung liegt auf den Gebieten des Umweltschutzes, der Erhaltung der Biotope und der Vermeidung menschlicher Gesundheitsrisiken.Recording substrates are used to clean contaminated media services, especially for cleaning surface waters and Soils related. This is preferably an adsorbent, coagulant and / or flocculant  for liquid hydrocarbons of the paraffins group, Olefins, naphthenes and aromatics and their modifiers. The application lies in the fields of environmental protection, the conservation of biotopes and the avoidance of human Health risks.

Die Aufnahmesubstrate, insbesondere Gummisubstrate sollen eine Dichte besitzen, die sich erheblich von der des zu reinigenden Mediums unterscheidet.The receiving substrates, in particular rubber substrates, are said to have a density that differs significantly from that of the cleaning medium differs.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Ver­ fahren zur Herstellung eines Aufnahmesubstrates zu schaf­ fen, das eine sehr geringe Dichte aufweist und ökologisch verträglich ist.The invention is therefore based on the object, a Ver drive to sheep to manufacture a receiving substrate fen, which has a very low density and ecological is tolerated.

Erfindungsgemäß wird die gestellte Aufgabe durch die Merk­ male des Hauptanspruches gelöst. Der Unteranspruch nennt ein besonders vorteilhaftes Trennmittel.According to the invention, the object is achieved by the Merk Male of the main claim solved. The subclaim calls a particularly advantageous release agent.

In einer besonders bevorzugten Ausführungsform der Erfin­ dung wird durch Zugabe von klebungsverhindernden Mitteln in Form von anorganischen Oxiden wie Talkum und Magnesia die Transportkapazität erhöht, sowie die Kompressionsfä­ higkeit des Substratverbundes vergrößert.In a particularly preferred embodiment of the invention dung by adding anti-stick agents in the form of inorganic oxides such as talc and magnesia the transport capacity increased, as well as the compression ability of the substrate composite increased.

Insbesondere ist die Formgestaltung der Gummisubstratteil­ chen dadurch optimiert, daß sie durch Anlagerung eines Stoffes mit geschlossenen Poren, der im weiteren als "Trennmittel" bezeichnet wird und in dem Gase enthalten sind, die den Auftrieb des Gummisubstrates in Wasser auch dann garantieren, wenn z. B. "schwere Heizöle" oder Orga­ nika mit einer Dichte großer 1 durch das Gummisubstrat ge­ bunden werden sollen. In particular, the shape of the rubber substrate part Chen optimized by the fact that by adding a Substance with closed pores, which is further referred to as "Release agent" is referred to and contained in the gases are the buoyancy of the rubber substrate in water too then guarantee if z. B. "heavy heating oils" or organization nika with a density greater than 1 through the rubber substrate should be bound.  

Durch den Ersatz der in der "wahren Dichte" höher als Was­ ser liegenden oxidischen Trennmittel durch einen spezi­ fisch wesentlich leichteren effektiveren und billigeren Stoff werden etwaige, die Substratteile vergrößernde Anla­ gerungen von anorganischen Oxiden wie Talkum oder Magnesi­ um ausgeglichen. Dadurch, daß das Trennmittel seinerseits ebenfalls eine gute Adsorptionsfähigkeit gegenüber den zu adsorbierenden Schadstoffen aufweist, ergibt sich ein syn­ ergistischer Effekt.By replacing the "true density" higher than what ser lying oxidic release agent by a speci fish much lighter more effective and cheaper Any material that enlarges the substrate parts becomes material wrestled with inorganic oxides such as talc or magnesi to be balanced. Because the release agent in turn also a good adsorption capacity compared to the has adsorbing pollutants, there is a syn ergistic effect.

Weiter wird durch den Einsatz eines Trennmittels auch dann die Auftriebswirkung des Adsorbens/Adsorbatverbundes auf­ recht erhalten, wenn Tenside auch in hoher Konzentration aus natürlichen oder künstlichen Quellen anwesend sind. Die umweltschädigende Sedimentation der Koagulate und Flockungen dieses Verbundes wird damit vermieden.The use of a release agent also continues the buoyancy effect of the adsorbent / adsorbate composite get right when surfactants even in high concentrations are present from natural or artificial sources. The environmentally harmful sedimentation of the coagulates and Flocculation of this bond is avoided.

Weiter wird durch den Einsatz eines absolut umweltfreund­ lichen Trennmittels jegliche Wechselwirkung mit Wasser oder im Boden befindliches Wasser, wie etwa chemischen Re­ aktionen oder PH-Wert-Veränderungen, verhindert. Mögliche biogene Abbaureaktionen werden jedoch nach wie vor zuge­ lassen und erforderlichenfalls kann eine katalytische Wir­ kung zum biogenen Abbau der Adsorbate hinzugefügt werden.Next is by using an absolutely environmentally friendly release agent any interaction with water or water in the ground, such as chemical Re actions or changes in pH, prevented. Possible however, biogenic degradation reactions are still being experienced leave and if necessary a catalytic We tion for the biogenic degradation of the adsorbates can be added.

Als natürlicher nachwachsender Rohstoff bietet sich an, den Gummisubstraten in Puderform adsorptiv Korkeichenrinde (quercus suber) hinzuzufügen. Durch maschinelles adsorpti­ ves Einarbeiten kann dieses fest an das Gummisubstrat ge­ bunden werden.As a natural renewable raw material, the rubber substrates in powder form adsorptive cork oak bark (quercus suber) to add. By machine adsorpti ves can work this firmly onto the rubber substrate be bound.

Die hervorragende Einsatzfähigkeit von Kork in Wasser und die Umweltverträglichkeit ist durch die Verwendung in der Wasserwirtschaft (Auftriebskörper) und in der Getränkein­ dustrie (Flaschenverschlüsse) belegt.The excellent usability of cork in water and the environmental impact is due to the use in the  Water management (buoyancy body) and in the beverage industry (bottle caps) occupied.
