Abstract

The paper sludge is processed into a sorbent through drying and powderizing. Through residual fibers, the sorbent is capable of binding liquids and storing them. The liquid can be discharged either through a mechanical treatment, e.g. centrifuging, or naturally over a longer period.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Sorptionsmittel aus anfallenden Schlämmen der Papierindustrie. Mögliche Einsatzgebiete des erfindungsgemäß gewonnenen Sorptionsmittel sind die Ölabsorption, der Einsatz als Matrixmaterial in Biofiltern und als Bodenverbesserungsmittel zur Stabilisierung des Wasserhaushalts.The invention relates to a method for producing Sorbent from resulting sludges from the paper industry. Possible areas of application of the invention Sorbents are the oil absorption, the use as Matrix material in biofilters and as a soil conditioner for Stabilization of the water balance.

Die Entsorgungskosten für Abfälle und Reststoffe zeigen eine kontinuierlich ansteigende Tendenz. Für Betriebe, in denen notwendigerweise große Mengen Reststoffe anfallen, stellt dies eine große Belastung dar. Aus diesem Grunde ist gerade die Papierindustrie, in den Ostseeanrainerstaaten ein besonders ausgeprägter Industriezweig, von dieser Entwicklung betroffen.The disposal costs for waste and residues show one continuously increasing trend. For companies in which this necessarily results in large amounts of residues represents a great burden. For this reason, it is precisely that Paper industry, a particularly in the countries bordering the Baltic Sea pronounced industry, affected by this development.

In Deutschland fallen jährlich ca. 2 Mio. t Reststoffe an, ca. 57% davon sind Schlämme. Diese Schlämme haben unterschiedliche Quellen innerhalb des Herstellungsprozesses und unterscheiden sich nach Art der eingesetzten Rohstoffe.In Germany approx. 2 million tons of residues are generated annually, approx. 57% of which are sludges. These muds have different ones Sources within the manufacturing process and differ according to the type of raw materials used.

Diese Schlämme werden heute durch Verbrennung und Deponierung entsorgt, wobei der Verbrennung eine etwas größere Bedeutung zukommt.These sludges are now incinerated and landfilled disposed of, with combustion being of somewhat greater importance comes to.

Die Verbrennung der Schlämme wird aufgrund des hohen Wassergehaltes als unrentabel angesehen. Wegen weiter steigender Deponie- und zukünftiger Emissionsabgaben ist die Papierindustrie gezwungen, neue Wege für die Verwertung ihrer Restprodukte zu suchen, um weiterhin auf dem Weltmarkt konkurrenzfähig zu sein. Darüber hinaus ist die Entsorgung beziehungsweise die Verminderung der Restprodukte auf einem ökologisch unbedenklichen Weg ein nicht zu unterschätzender Imagegewinn für die Papierproduzenten.The combustion of the sludge is due to the high Water content viewed as unprofitable. Because of increasing The paper industry is landfill and future emission taxes forced to find new ways of recycling their residual products looking to continue to be competitive in the global market. In addition, the disposal or reduction of the remaining products in an ecologically harmless way To be underestimated image gain for the paper producers.

Es ist bekannt, daß Sorptionsmittel aus Papier oder Sägespänen hergestellt werden können. Hier wird die Absorptionswirkung der Faser genutzt. Da auch im Papierschlamm eine Restfaser ist, kann dieser zur Herstellung von Sorptionsmitteln ebenfalls eingesetzt werden. It is known that sorbents are made of paper or sawdust can be produced. Here the absorption effect of the Fiber used. Since there is also a residual fiber in the paper sludge this is also used for the production of sorbents become.  

Der in dem Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, ein Verfahren vorzuschlagen, das unter Ausnutzung der Absorptionswirkung der Restfaser der Papierschlämme ermöglicht, Sorptionsmittel direkt aus diesem Schlämmen herzustellen.The invention specified in the claim lies the problem to propose a procedure that takes advantage of the Absorption effect of the residual fiber of the paper sludge enables To produce sorbents directly from this slurry.

Erfindungsgemäß wurde gefunden, daß aus dem Papierschlamm, vor allem durch Trocknen und Vermahlen ein Sorptionsmittel direkt hergestellt werden kann, das durch seine Restfasern in der Lage ist, Flüssigkeiten zu binden und zu speichern und daß die Flüssigkeit entweder durch mechanische Behandlung (z. B. Zentrifugieren) oder langfristig durch natürlichen Ausgleich wieder abgibt.According to the invention it was found that from the paper sludge, before all by drying and grinding a sorbent directly can be produced by its remaining fibers is to bind and store liquids and that the Liquid either by mechanical treatment (e.g. Centrifugation) or long-term through natural balancing releases again.

Das Sorptionsmittel kann sowohl pulverförmig verwendet oder zur besseren Handhabung, evtl. unter Zugabe von geringen Mengen an eigenschaftsverbessernden Zusatzstoffen und eines Binders, granuliert werden. Das Produkt zeichnet sich ferner dadurch aus, daß es durch die Flüssigkeitsabgabe mehrmals verwendbar ist. Die Beseitigung des eingesetzten; benutzten? Produktes nach dem letzten Gebrauch kann durch Verbrennung erfolgen.The sorbent can be used in powder form or better handling, possibly with the addition of small amounts of property-improving additives and a binder, be granulated. The product is also characterized by that it can be used several times due to the liquid release. The Elimination of the used; used? Product after last use can be done by incineration.
