Description
Einrichtung zur Anreicherung natürlicher stehender Gewässer mit Sauerstoff Die Erfindung bezieht sich auf eine Einrichtung zur Anreicherung naturlich stehender Gewässer mit Sauerstoff, vornehmlich zur Anreicherung mit Sauerstoff inn 13ereicl des Hypolimnions des Gewässers.Facility for the enrichment of natural standing water with oxygen The invention relates to a device for the enrichment of naturally standing Waters with oxygen, primarily for enrichment with oxygen in 13ereicl of the hypolimnion of the water.
In den vergangenen Jahren wurde eine zunehmende Eutrophierung stehender Gewässer beobachtet. lür das Land Bayern ist dies z. B. in der Monographie "Der Wassergüteatlas11, herausgeber: Prof. II. Liebmann, München, 1969, dokumentiert.In recent years, increasing eutrophication has become more permanent Waters observed. For the state of Bavaria this is z. B. in the monograph "Der Water quality atlas11, publisher: Prof. II. Liebmann, Munich, 1969, documented.
Bei zunehmender Verschmutzung der Gewässer sinken zu große Mengen organischer Substanz in das llypolimnion des Gewässers ab und können dort nicht mehr aorob abgebaut werden, weil der hierzu erforderliche Sauerstoff nicht in ausreichendem Maße zur Verfügung steht.With increasing pollution of the waters, too large amounts sink organic matter in the llypolimnion of the water and cannot there more aorob are broken down because the oxygen required for this is insufficient Dimensions is available.
Es kommt dann zu ausgedehnten Zonen mit anaerober Zersetzung. Eine Selbstreinigung des Gewässers ist dann nicht mehr bzw. nur über einen langen Zeitraum möglich, selbst wenn es gelingt, die weitere Schmutzzufuhr zu unterbinden. Durch künstliche Zufuhr von Sauerstoff im Bereich des ilypolirinions läßt sich hingegen der Reinigungsvorgang erheblich beschleunigen.There are then extensive zones of anaerobic decomposition. One Self-cleaning of the water is then no longer or only over a long period of time possible, even if it is possible to prevent the further supply of dirt. By Artificial supply of oxygen in the area of the ilypolirinions, however, can be speed up the cleaning process considerably.
Zur Sauerstoffanreicherung in den tieferen Schichten eines Gewässers wurde vorgeschlagen, mit hilfe von Kompressoren und Druckrohren Luft einzublasen, die sich im Wasser teilweise löst und den erforderlichen Sauerstoff für einen aeroben Abbau liefert. I)ie listen derartiger Anlagen und ihr Energieverbrauch sind relativ hoch. Sie erfordern zudem eine aufwendige iartung, und ihr Standort kann nur mit relativ großem Arbeitsaufwand Verändert werden. Bei Einrichtungen der genannten Art sind werner zusitzliche Maßnahmen erforderlich, durch die verhindert wird, daß durch das Einblasen von Luft die naturlicile Schichtung des Gewässers verändert wird.For oxygen enrichment in the deeper layers of a body of water it was proposed to inject air with the help of compressors and pressure pipes, which partially dissolves in the water and provides the necessary oxygen for an aerobic Dismantling supplies. I) he lists of such systems and their energy consumption are relative high. They also require extensive maintenance, and their location can only be with relatively large amount of work to be changed. With facilities of the named Art additional measures are required to prevent by blowing in air changes the natural stratification of the water will.
Der Erfindung liegt die Aufgabe zugrunde, eine Linrichtung zu schaffen, die mit rclativ niedrigen tnlaekosten und niedrigem Arbeitsaufwand instllierbar ist und die es gestattet, Sauerstoff in das Hypolimnion eines Gewässers, also in tieferen Schichton des Gewässers mit relativ niedrigem Energieaufwand einzubringen.The invention is based on the object of creating a Linrichtung, which can be installed with relatively low service costs and low workload and which allows oxygen into the hypolimnion of a body of water, i.e. in to bring in deeper strata of the water with relatively low energy expenditure.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, das mindestens eine an einem Schwimmkdrper isoliert aufgehängt und mit Durchbrüchen versehene flachige Elektrode in waagrechter Lage bis in die Nähe des Gewässergrundes abgesenkt und an eine einpolig geerdete Wechselstromquelle angesclllossen ist. Dabei wird das Wasser in seine Bestandteile Wasserstoff und Sauerstoff auf elektrolytischem stege zersetzt, wobei der Sauerstoff mit dem Wasser in Lösung gellt und der Wasserstoff in ungefährlicher feiner Verteilung aufsteigt und sich in der Luft verflüchtigt.This object is achieved according to the invention by the at least one Suspended from a floating body in isolation and flat with perforations Electrode lowered in a horizontal position to near the bottom of the water and to a single-pole earthed AC power source is connected. Thereby the water is in its constituent parts hydrogen and oxygen on an electrolytic basis webs decomposed, the oxygen and the water in solution and the hydrogen rises in harmless fine distribution and evaporates in the air.
Gemäß einer Weiterbildung der Erfindung bestehen die Blektroden aus mit Maschendraht bespannt bespannton Rahmen oder aus perforierten Blechen, wodurch eine großflächige Verteilung des gebildeten Sauerstoffs gewährleistet ist.According to a further development of the invention, the lead electrodes consist of covered with wire mesh covered frame or made of perforated sheet metal, whereby a large-area distribution of the oxygen formed is guaranteed.
In weiterer Ausgestaltung der Erfindung ist das die Elektroden versorgende Kabel ebenfalls an Schwimmkörpern aufgehängt, wodurch ein gegebenenfall erforderlicher Wechsel des Standortes der gesamten Linrichtung in einfacher Weise durchführbar ist.In a further embodiment of the invention, it is the one that supplies the electrodes Cable also hung on floats, which may be necessary Change of the location of the entire Linrichtung can be carried out in a simple manner is.
Da die Stromversorgung zweckmäßigerweise aus einem vorhandenen Drehstromnetz vorgenommen wird, ist gemäß einer Weiterbildung der Erfindung vorgesehen, an einem Schwimmkörper jeweils drei an den Spitzen eines gleichseitigen Dreiecks aufgehängte Llektroden anzuordnexl.Since the power supply expediently from an existing three-phase network is made, is provided according to a development of the invention, on one Float three each suspended from the tips of an equilateral triangle Leads to be arranged
