Abstract

The invention relates to a method for treating a liquid, comprising the steps: introducing the liquid to be treated into a reaction chamber, subjecting the liquid to ultrasound, irradiating the liquid with UV radiation as the liquid is being subjected to ultrasound, and discharging the treated liquid from the reaction chamber. The method is characterised in that as the liquid is being subjected to ultrasound and is being irradiated with UV-radiation, the liquid is simultaneously permeated by a gas.

Description

Verfahren zur Behandlung einer Flüssigkeit Die Erfindung betrifft ein Verfahren zur Behandlung einer Flüssigkeit.  Method for treating a fluid The invention relates to a method for treating a fluid.
Die Erfindung betrifft insbesondere ein Verfahren zur Behandlung von Ballastwasser, Brüdenwasser, Kondenswasser aus Klimaanlagen, zur Aufbereitung von Trinkwasser oder zur Aufbereitung von Abwässern, z.B. Toilettenabwasser. More particularly, the invention relates to a method of treating ballast water, vapor water, condensed water from air conditioners, treating drinking water or treating waste water, e.g. Toilet waste.
Aus der DE 20 2004 020 459 Ul ist bereits eine„Vorrichtung zur Behandlung von Flüssigkeiten" bekannt, mit der der Anteil an unerwünschten Fluidbestandteilen, beispielsweise Keime, Sporen, Herbizide, Fungizide, Pestizide, Restdüngemittel, Restmedikamente, Toxine und insbesondere Endotoxine, verringert werden kann. Dieses wird durch gleichzeitiges Ein- wirken einer Ultraschall- und einer UV-Quelle auf die zu behandelnde Flüssigkeit erreicht. From DE 20 2004 020 459 Ul a "device for the treatment of liquids" is already known, with the proportion of undesirable fluid components, such as germs, spores, herbicides, fungicides, pesticides, residual fertilizers, residual drugs, toxins and in particular endotoxins are reduced This is achieved by simultaneously applying an ultrasonic and a UV source to the liquid to be treated.
Wenngleich das vorbekannte Verfahren bereits gute Ergebnisse erzielt, ist es Aufgabe der Erfindung, das vorgenannte Verfahren im Hinblick auf dessen Effizienz weiter zu verbessern. Diese Aufgabe wird durch das Verfahren mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder. Although the previously known method has already achieved good results, the object of the invention is to further improve the aforementioned method with regard to its efficiency. This object is achieved by the method having the features of claim 1. The subclaims reflect advantageous embodiments of the invention.
Grundgedanke der Erfindung ist es, die zu behandelnde Flüssigkeit nicht nur zeitgleich mit Ultraschall und UV-Strahlung zu behandeln, sondern die Flüssigkeit währenddessen von ei- nem Gas durchströmen zu lassen. Dabei entsteht eine vorteilhafte Wechselwirkung ausThe basic idea of the invention is not only to treat the liquid to be treated simultaneously with ultrasound and UV radiation, but also to let the liquid flow through it by means of a gas. This results in a beneficial interaction
Gasluftblasen, Ultraschall und UV-Strahlung, mit der eine verbesserte Reinigung s Wirkung erzielt werden kann. Gas bubbles, ultrasound and UV radiation, with which an improved cleaning effect can be achieved.
Bevorzugt ist das die Flüssigkeit durchströmende Gas Luft. Preferably, the gas flowing through the liquid is air.
Alternativ ist das die Flüssigkeit durchströmende Gas ein Edelgas oder ein Edelgas aufweisendes Gasgemisch. Besonders gute Behandlungsergebnisse können erzielt werden, wenn das Gas in der Flüssigkeit als feinstverteilte Gasbläschen vorliegt. Hierzu wird das Gas der Flüssigkeit bevorzugt durch ein (engmaschiges) Sieb oder durch ein Keramikelement zugeführt, um auch eine möglichst homogene Feinverteilung des Gases zu erreichen. Alternatively, the gas flowing through the liquid is a noble gas or a gas mixture having noble gas. Particularly good treatment results can be achieved if the gas is present in the liquid as finely divided gas bubbles. For this purpose, the gas of the liquid is preferably supplied through a (close-meshed) sieve or through a ceramic element in order to achieve as homogeneous a fine distribution of the gas as possible.
Bevorzugt werden dabei die Flüssigkeit und das Gas im Reaktionsraum im Gleichstrom geführt, wobei die Flüssigkeit besonders bevorzugt, beispielsweise durch an der Innenwandung des Reaktionsraums angeordnete Strömungsabweiser, wenigstens teilweise eine chaotische Strömung ausführend geführt wird. In this case, the liquid and the gas are preferably conducted in the reaction space in cocurrent, wherein the liquid is particularly preferably performed, for example, by at the inner wall of the reaction space arranged flow deflector, at least partially carrying out a chaotic flow.
Grundsätzlich ist es aber auch möglich, Flüssigkeit und Gas im Gegenstrom zu führen oder das Gas quer zur Strömungsrichtung der Flüssigkeit in die Flüssigkeit einzuleiten. In principle, it is also possible to carry liquid and gas in countercurrent or to introduce the gas transversely to the flow direction of the liquid in the liquid.
