Description
Die Erfindung betrifft ein Verfahren zur umweltschonenden Behandlung des bei der Olivenpressung anfallenden Abwassers. Dieses Abwasser enthält eine Anzahl von Phenolderivaten, was bei der Weiterverwendung zu einer starken Geruchsbelästigung führt. Mit der Erfindung soll dieses Abwasser einer umweltfreundlichen Verwendung zugänglich gemacht werden.The invention relates to a method for the environmentally friendly treatment of the waste water produced during olive pressing. This waste water contains a number of phenol derivatives, which leads to a strong odor nuisance when used further. With the invention, this waste water should be made accessible to an environmentally friendly use.
Stand der TechnikState of the art
Aus der
Die
Gemäß
Das durch die Verdunstung erhaltene Konzentrat hat einen Trockensubstanzgehalt von 30 bis 50 % und wird der Trocknung zugeführt, um die in dem Abwasser enthaltenen organischen Substanzen in Pulverform zu erhalten.The concentrate obtained through evaporation has a dry matter content of 30 to 50% and is sent for drying in order to obtain the organic substances contained in the waste water in powder form.
Da hierbei mit dem Wasser auch die darin enthaltenen Geruchsstoffe - insbesondere die Phenolderivate - verdunstet werden, bleibt auch hiermit das Problem der Geruchsbelästigung bestehen.Since the odorous substances contained therein - in particular the phenol derivatives - are evaporated with the water, the problem of odor nuisance also remains.

Die in der
Aufgabe der Erfindungobject of the invention
Somit ergibt sich als Aufgabe der Erfindung, ein Verfahren zur umweltschonenden Behandlung des bei der Olivenpressung anfallenden Abwassers vorzuschlagen, das alle umweltschädlichen Inhaltsstoffe so eliminiert, dass das entstehende Wasser einer unschädlichen Verwendung zugeführt werden kann.The object of the invention is therefore to propose a method for the environmentally friendly treatment of the waste water produced during olive pressing, which eliminates all environmentally harmful ingredients in such a way that the water produced can be put to harmless use.
Beschreibung der ErfindungDescription of the invention
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren mit den im Hauptanspruch beschriebenen Schritten gelöst.According to the invention, this object is achieved by a method with the steps described in the main claim.
In den Unteransprüchen werden weitere Schritte zur effektiveren Nutzung der Erfindung vorgeschlagen.Further steps to use the invention more effectively are proposed in the subclaims.
Erfindungsgemäß wird das Abwasser aus der Olivenölproduktion, das neben feststofflichen Abfällen im Zuge der Olivenverarbeitung anfällt, in einem ersten Schritt vorgereinigt, indem durch Zusatz von Chelatbildnern in Form von Schwermetall-Ionen bei einem pH-Wert von 4,5 bis 5,5 die im Abwasser enthaltenen Phenole gebunden und ausgeflockt werden.According to the invention, the waste water from olive oil production, which occurs in addition to solid waste in the course of olive processing, is pre-cleaned in a first step by adding chelating agents in the form of heavy metal ions at a pH of 4.5 to 5.5 The phenols contained in the waste water are bound and flocculated.
Die dadurch ausgefällten Flocken werden durch ein Filtersieb mit einer Maschenweite von 0,08 bis 0,12 mm abgeschieden.The flakes thus precipitated are separated through a filter screen with a mesh size of 0.08 to 0.12 mm.
Anschließend wird durch Zusatz von in Wasser gelöster Asche der pH-Wert auf einen Wert von 8 bis 9 erhöht. Durch den gleichzeitigen Zusatz von gemahlenem Aktivkoks werden die restlichen Phenole gebunden.The pH value is then increased to a value of 8 to 9 by adding ash dissolved in water. The remaining phenols are bound by the simultaneous addition of ground activated carbon.
Die mit den Reststoffen beladenen Aktivkohlepartikel werden darauffolgend durch ein Filtersieb mit einer Maschenweite von 0,008 bis 0,012 mm abgeschieden.The activated carbon particles loaded with the residues are then separated through a filter screen with a mesh size of 0.008 to 0.012 mm.
Als letzter Schritt werden durch Zusatz von aktivem Sauerstoff in Form von Oxidationsmitteln noch verbliebene organische Verbindungen zu Kohlendioxid und Wasser umgesetzt. Das hierbei entstehende Kohlendioxid wird in Algenbecken gebunden.As a final step, the remaining organic compounds are converted into carbon dioxide and water by adding active oxygen in the form of oxidizing agents. The resulting carbon dioxide is bound in algae tanks.
Durch Verkokung des getrockneten, bei der Pressung anfallenden Ölkuchens wird ein Aktivkoks erzeugt, der gemahlen dem Prozess zur Bindung restlicher Phenole zugeführt wird.Activated coke is produced by coking the dried oil cake from the pressing process, which is then ground and fed into the process for binding the remaining phenols.
Alle in den Filtersieben ausgeschiedenen Substanzen werden getrocknet und durch thermische Behandlung für die Wiederverwendung im Prozess aufbereitet.All substances separated in the filter screens are dried and prepared for reuse in the process by thermal treatment.
Ein Teil des abgefilterten Aktivkokses wird zur Gewinnung der im Prozess benötigten Energie verbrannt. Die dabei anfallende Asche wird im Prozess eingesetzt.Part of the filtered activated carbon is burned to generate the energy needed in the process. The resulting ash is used in the process.
Ausführungsbeispielexample
Die Erfindung soll im Folgenden in Form eines Ausführungsbeispiels erläutert werden.The invention is to be explained below in the form of an exemplary embodiment.
Das Abwasser aus Betrieben zur Olivenölproduktion, das neben feststofflichen Abfällen im Zuge der Olivenverarbeitung anfällt, wird durch Zusatz chelatbildender Kupfer-Ionen bei einem pH-Wert 5 versetzt, wodurch die im Abwasser enthaltenen Phenole gebunden und ausgeflockt werden.The waste water from olive oil production plants, which is produced in addition to solid waste in the course of olive processing, is treated with the addition of chelating copper ions at a pH value of 5, which binds and flocculates the phenols contained in the waste water.
Die dadurch ausgefällten Flocken werden durch ein Filtersieb mit einer Maschenweite von 0,08 mm abgeschieden und einer thermischen Verwertung zugeführt.The flakes thus precipitated are separated through a filter screen with a mesh size of 0.08 mm and fed to thermal recycling.
Anschließend wird durch Zusatz von in Wasser gelöster Asche der pH-Wert auf einen Wert von 8 erhöht. Durch den gleichzeitigen Zusatz von gemahlenem Aktivkoks werden die restlichen Phenole gebunden.The pH value is then increased to a value of 8 by adding ash dissolved in water. The remaining phenols are bound by the simultaneous addition of ground activated carbon.
Die mit den Reststoffen beladenen Aktivkohlepartikel werden darauffolgend durch ein Filtersieb mit einer Maschenweite von 0,01 mm abgeschieden.The activated carbon particles loaded with the residues are then separated through a filter screen with a mesh size of 0.01 mm.
Als letzter Schritt werden durch Zusatz von aktivem Sauerstoff in Form von Wasserstoffperoxid noch verbliebene organische Verbindungen zu Kohlendioxid und Wasser umgesetzt. Das hierbei entstehende Kohlendioxid wird nach Zusatz von Algenbrut in einem Algenbecken als Biomasse gebunden.As a final step, the remaining organic compounds are converted into carbon dioxide and water by adding active oxygen in the form of hydrogen peroxide. After the addition of algae spawn, the resulting carbon dioxide is bound as biomass in an algae tank.
Durch Verkokung von getrocknetem Ölkuchen wird Aktivkoks erzeugt, der dem Prozess zur Bindung der restlichen Phenole zugeführt wird.Activated coke is produced by coking dried oil cake and is fed into the process to bind the remaining phenols.
Ein Teil des abgefilterten Aktivkokses wird zur Gewinnung der im Prozess benötigten Energie verbrannt. Hierbei anfallende Asche wird im Prozess eingesetzt.Part of the filtered activated carbon is burned to generate the energy needed in the process. The resulting ash is used in the process.
