Description

Verfahren zum Begasen oder Belüften von Flüssigkeiten, insbesondere Abwasser, medizinischen Bädern od. dgl.Process for gassing or aerating liquids, in particular Sewage, medical baths or the like.

Zusatz zum Patent: 1153 725 In dem Hauptpatent ist ein Begasungsverfahren beschrieben, bei dem das Gas der Flüssigkeit höchstens im Verhältnis von 1/lo Volumenanteil zugesetzt wird und im Flüssigkeit-Gas-Gemisch vor dem Eintritt in den Begasungsbehälter ein überdruck von mindestens 0,5 atü erzeugt wird.Addition to the patent: 1153 725 The main patent describes a gassing process in which the gas is added to the liquid in a ratio of no more than 1 / lo volume fraction and an overpressure of at least 0.5 in the liquid-gas mixture before entering the gassing container atü is generated.

Versuche haben gezeigt, daß unter diesen Umständen eine ganz unerwartet gute Feinstverteilung des Gases in der Flüssigkeit erzielt wird, was vermutlich darauf zurückzuführen ist, daß das Gas unter der Druckwirkung sich zunächst in der Flüssigkeit löst und bei der Entspannung im Begasungsbehälter in Form kleinster Blasen aufschäumt, die sodann in drucklosem Zustand während des sehr langsamen Aufstiegs wieder völlig in Lösung gehen.Tests have shown that under these circumstances a completely unexpected good fine distribution of the gas in the liquid is achieved, which is presumably is due to the fact that the gas is initially under the pressure in the Liquid dissolves and in the expansion in the gas tank in the form of the smallest Bubbles foaming, which then in a depressurized state during the very slow ascent go completely into solution again.

Um nun in allen Fällen eine optimale Dosierung des Gases vornehmen zu können, wird vorgeschlagen, daß das Flüssigkeit-Gas-Gemisch unter mindestens einem solchen Druck und höchstens einem solchen Volumenanteil von Gas zur Flüssigkeit in den Begasungsbehälter geleitet wird, daß das in die Flüssigkeit eingeführte Gas infolge des im Flüssigkeit-Gas-Gemisch vor dem Eintritt in den Begasungsbehälter erzeugten Druckes in Lösung geht und nach der Entspannung im B egasungsbehälter in Form von feinsten Blasen aufschäumt.In order to make an optimal dosage of the gas in all cases to be able to, it is proposed that the liquid-gas mixture below at least such a pressure and at most such a volume fraction of gas to liquid is passed into the gassing tank that the gas introduced into the liquid as a result of the liquid-gas mixture before entering the gas tank generated pressure goes into solution and after the relaxation in the gassing tank foams in the form of the finest bubbles.

Dadurch ist es möglich, für jedes beliebige Flüssigkeit-Gas-Gemisch das erwünschte Begasungsverhältnis zu erzielen, ohne daß zusätzliches Gas verbraucht wird. Ferner ist es möglich, mit verschiedenen Drücken und Mischungsverhältnissen zu arbeiten, sofern nur das Gas vor seinem Eintritt in den Begasungsbehälter gelöst wird.This makes it possible for any liquid-gas mixture to achieve the desired gassing ratio without consuming additional gas will. It is also possible to use different pressures and mixing ratios to work, provided only the gas is dissolved before it enters the gas tank will.

Die Erfindung soll nun an Hand von zwei Ausführungsbeispielen geschildert werden. Im ersten Fall soll das Verfahren bei einer Belebtschlammanlage beschrieben werden, im zweiten Fall wird seine Anwendung bei medizinischen Bädern geschildert.The invention will now be described on the basis of two exemplary embodiments will. In the first case, the process is to be described for an activated sludge plant in the second case its use in medicinal baths is described.

Gemäß dem Hauptpatent soll eine Belebtschlanunanlage mittels einer Druckpumpe umgewälzt werden. Dabei soll Sauerstoff an der Druckseite oder Saugseite der Druckpumpe zugeführt werden. Infolge der Druckwirkung soll das Wasser-Sauerstoff-Gemisch auf 0,5 atü verdichtet und über Druckdüsen nahe dem Boden in das Belebtschlammbecken geleitet werden. Dabei soll die zugeführte Sauerstoffmenge so bemessen werden, daß der Sauerstoff in der Druckleitung voll gelöst wird, und nach seiner Entspannung am Boden des Belebtschlammbehälters in feinsten Blasen aufschäumt. Dies ruft eine innige Vermischung des Wassers mit den Sauerstoffblasen hervor, wodurch der zugehörige Belebtschlamin mit Sauerstoff angereichert wird. Dadurch wird der biologische Abbau des Abwassers gefördert.According to the main patent, an activated sludge system is to be circulated by means of a pressure pump. Oxygen should be supplied to the pressure side or suction side of the pressure pump. As a result of the pressure effect, the water-oxygen mixture is to be compressed to 0.5 atmospheres and passed through pressure nozzles near the bottom into the activated sludge basin. The amount of oxygen supplied should be measured in such a way that the oxygen in the pressure line is completely dissolved and, after it has been released, foams in very fine bubbles at the bottom of the activated sludge container. This causes the water to mix intimately with the oxygen bubbles, as a result of which the associated activated sludge is enriched with oxygen. This promotes the biological degradation of the wastewater.

Im zweiten Fall sollen medizinische Bäder von einer Druckwasserleitung gespeist werden. Mittels eines Druckspeichers wird Kohlensäure in die Druckwasserleitung eingespeist, wobei die Kohlensäuremenge so bemessen wird, daß die Kohlensäure in der Druckwasserleitung voll gelöst wird. Durch Drucköffnungen wird das kohlensäurehaltige Wasser in die medizinischen Bäder eingespeist, wobei die Kohlensäure sich entspannt und in kleinsten Blasen aufschäumt. Dadurch findet eine innige Verbindung der Kohlensäure mit dem in den Bädern befindlichen Wasser statt, so daß dessen pH-Gehalt ansteigt.In the second case, medical baths should be powered by a pressurized water pipe be fed. By means of a pressure accumulator, carbonic acid is released into the pressurized water pipe fed in, the amount of carbonic acid being measured so that the carbonic acid in the pressure water line is fully released. Through pressure openings the carbonated Water fed into the medicinal baths, whereby the carbonic acid relaxes and foams up in tiny bubbles. This creates an intimate connection between the carbonic acid with the water in the baths, so that its pH content rises.

In beiden Fällen findet eine Höchstausnutzung des eingetragenen Gases statt, da Druck und Volumenanteil so gewählt sind, daß keine großen Blasen auftreten und infolgedessen die Verluste gering sind. . In both cases, maximum utilization of the gas introduced takes place, since the pressure and volume fraction are chosen so that no large bubbles occur and, as a result, the losses are low. .

Die Erfindung kann in allen in dem Hauptpatent genannten Anwendungsbeispielen und Anwendungsgebieten zur Anwendung gelangen.The invention can be used in all of the application examples mentioned in the main patent and areas of application.
