Description

Verfahren zur Elektroflotation von Schmutzwässern sind all­ gemein bekannt. Sie arbeiten stets mit Gleichstromnieder­ spannung, wobei die Elektroden entweder beständig bleiben oder durch Elektrolyse aufgelöst werden. Als Elektroden sind u. a. Eisen und Aluminium bekannt, vgl. z. B. die OS 22 08 076, OS 23 13 640 und OS 15 17 444. In den Literaturstellen ist die Aufeinanderfolge und die Stellung der Aluminiumelektro­ den nicht definiert, meist liegen sie bereits im Anfang der Reaktorzelle.Processes for the electroflotation of waste water are all common knowledge. You always work with direct current lowers voltage, with the electrodes either remaining stable or be dissolved by electrolysis. As electrodes are u. a. Known iron and aluminum, cf. e.g. B. the OS 22 08 076, OS 23 13 640 and OS 15 17 444. In the references the sequence and the position of the aluminum electro the undefined, mostly they are in the beginning of the Reactor cell.

Der Erfindung liegt die Aufgabe zugrunde, eine Weiterbildung und Verbesserung der bekannten Elektroflotationsverfahren zu erreichen. Die Aufgabe wird durch die in den Ansprüchen beschriebenen Merkmale gelöst.The invention has for its object a training and improvement of the known electroflotation processes to reach. The task is defined in the claims described features solved.

Erfindungsgemäß wird unter Verwendung von durch Elektrolyse sich verbrauchende Elektroden aus Eisen und Aluminium das Schmutzwasser einem System von kaskadenartig angeordneten Elektroden zugeführt, von denen das erste Plattenpaket aus Eisen und das zweite aus Aluminium besteht. According to the invention using electrolysis consumable electrodes made of iron and aluminum Dirty water in a system of cascades Electrodes supplied, from which the first plate pack Iron and the second is made of aluminum.  

Nach Brockhaus der Naturwissenschaft und Technik bedeutet in der chemischen Technik "Kaskade" eine Anordnung über- oder hintereinander geschalteter gleichartiger Geräte usw., die das Material stufenweise durchläuft. Weiter sind sogenann­ te Kaskadenkühler bekannt, bei denen die Strömung durch gegen­ seitig versetzte Bleche geleitet wird.According to Brockhaus, this means natural science and technology in chemical engineering "cascade" an arrangement over or similar devices connected in series etc., that the material goes through in stages. Next are so-called te cascade cooler known, in which the flow through against offset sheet metal is guided.

Bei der Erfindung werden senkrechtstehende, bis zum Gefäß­ boden reichende, gegebenenfalls versetzte Plattenpakete verwen­ det, so daß das Schmutzwasser die Plattenpakete zwangsläufig mäanderartig durchlaufen muß. Dabei sind also die Eisen- und Aluminiumplatten kaskadenartig hintereinander geschaltet.In the invention are vertical, up to the vessel Use floor-level, possibly offset plate packs det, so that the dirty water inevitably the plate packs must go through like a meander. So the iron and Aluminum plates cascaded in series.

Es hat sich ergeben, daß bei dieser Aufeinanderfolge der Plattenpakete eine Flotation in einem weiten pH-Bereich möglich ist und ein Chemikalienzusatz in den meisten Fäl­ len überflüssig ist.It has been found that with this succession of Plate packs flotate in a wide pH range is possible and a chemical additive in most cases len is unnecessary.

Durch das Verfahren und die Vorrichtung zu seiner Ausfüh­ rung nach der Erfindung werden die bisher bekannten Ver­ fahren wesentlich verbessert, weil durch die neue Elek­ trodenanordnung ohne Zusatz weiterer Chemikalien oder Bindestoffe bereits eine sehr weitgehende und in den mei­ sten Fällen völlig ausreichende Klärung in einem großen pH-Bereich möglich geworden ist.By the method and the device for its execution tion according to the invention, the previously known Ver driving significantly improved because of the new Elek Trode arrangement without the addition of other chemicals or Binders already a very extensive and in most cases In most cases, sufficient clarification in a large pH range has become possible.

In den Figuren soll das Verfahren und die Vorrichtung zur Durchführung des Verfahrens näher erläutert werden. InIn the figures, the method and the device for Implementation of the method are explained in more detail. In

Fig. 1 ist oben das Plattenpaket in Seitenansicht darge­ stellt, während unten das Plattenpaket in Draufsicht zu sehen ist, das vom Schmutzwasser in Pfeilrichtung mäander­ förmig durchflossen wird. Hier wird das Schmutzwasser ge­ klärt und desinfiziert, man erzielt außerdem einen Stripp- Effekt. Auch die CSB- und BSB-Werte werden erheblich ver­ bessert. Metalle werden ausoxydiert, Emulsionen werden ge­ brochen, Ölanteile in die Schaumphase getrieben und das Schmutzwasser geklärt. Durch die elektrolytische Wirkung zwischen Anode und Kathode werden durch H20-Trennung Feinst- Gasbläschen erzeugt, wobei der freiwerdende Sauerstoff äußerst intensiv die im Schmutzwasser befindlichen Substanzen oxydiert. Fig. 1 is above the plate pack in a side view Darge, while below the plate pack can be seen in plan view, which flows through the dirty water in a meandering manner in the direction of the arrow. The dirty water is clarified and disinfected here, and a stripping effect is also achieved. The COD and BOD values will also be significantly improved. Metals are oxidized, emulsions are broken, oil components are driven into the foam phase and the dirty water is clarified. Due to the electrolytic effect between the anode and cathode, very fine gas bubbles are generated by H20 separation, with the released oxygen extremely intensely oxidizing the substances in the dirty water.

Die Gasbläschen treiben die gebildeten Flocken an die Ober­ fläche, so daß dort ein stabiles Schaumbett entsteht. Schwe­ re Schmutzpartikel wie z. B. Sand sinken in den Bodenbereich. Zwischen dem oberen Schaumbett und dem unteren Schwerschmutz­ anteil entsteht eine Klarphase.The gas bubbles drive the flakes formed to the top area, so that there is a stable foam bed. Schwe re dirt particles such. B. Sand sink into the floor area. Between the top foam bed and the bottom heavy dirt share there is a clear phase.

Fig. 2 zeigt eine komplette Anlage zur Ausführung des Ver­ fahrens. Fig. 2 shows a complete system for carrying out the process.

Das Schmutzwasser tritt in den Reaktorbehälter 3, in dem die kaskadenförmig angeordneten Plattenpakete, von denen das erste aus Eisen und das folgende aus Aluminium besteht, angebracht sind, ein und läuft von dort in ein Klärbecken 4, in dem sich schräg gegen die Strömungsrichtung stehende Platten 5 befinden. Das an der Oberfläche der Behälter 3 und 4 gebildete Schaumbett wird durch eine Vorrichtung 7 abgesaugt oder abgeräumt. Noch verbleibende Schaumreste ge­ langen in ein Schaumbecken 6. Die Schwerschmutzteile am Bo­ den der Behälter 3, 4 und 6 werden durch Rohre 8 abgeführt.The dirty water enters the reactor vessel 3 , in which the cascade-shaped plate packs, the first of which are made of iron and the following of aluminum, are attached, and from there it runs into a clarifier 4 , in which plates are positioned at an angle to the direction of flow 5 are located. The foam bed formed on the surface of the containers 3 and 4 is suctioned off or cleared away by a device 7 . Remaining foam residues reach into a foam basin 6 . The heavy dirt parts on the Bo of the container 3, 4 and 6 are discharged through pipes 8 .
