Die Erfindung bezieht sich auf ein Verfahren zur Einleitung von mit Luft angereichertem Wasser in das Erdreich, wobei das Wasser am unteren Ende eines vertikal verlaufenden, geschlossenen Abschnittes einer Wasserleitung austritt.The invention relates to a method for introducing air-enriched water into the ground, the water emerging at the lower end of a vertically running, closed section of a water pipe.
Aus EP 0 548 768 ist ein derartiges Verfahren bekanntgeworden. Die Zufuhr von Luft, welche unter Druck mittels einer Pumpe erfolgt, hat dabei den Zweck, leicht lösliche Verunreinigungen durch Unterdruckverdampfung aus dem Grundwasser zu entfernen.Such a method has become known from EP 0 548 768. The supply of air, which takes place under pressure by means of a pump, has the purpose of removing easily soluble impurities from the groundwater by means of vacuum evaporation.
Der Erfindung liegt das Problem zugrunde, daß bei der Grundwasseranreicherung mittels Sickerbrunnen das zugeführte Wasser einen Mindestgehalt an Sauerstoff auf weisen muß. Es ist daher ein gezielter Sauerstoffeintrag in das Anreicherungswasser erforderlich, der mit möglichst geringem konstruktivem Aufwand erreicht werden soll. Erfindungsgemäß ist hiezu vorgesehen, daß die Luft durch eine mit der Atmosphäre in Verbindung stehende Luftleitung in einen Bereich im Inneren der Wasserleitung geleitet wird, in welchem Unterdrück herrscht.The invention is based on the problem that in the case of groundwater enrichment by means of seepage wells, the water supplied must have a minimum oxygen content. A targeted introduction of oxygen into the enrichment water is therefore necessary, which should be achieved with the least possible design effort. According to the invention it is provided that the air is conducted through an air line connected to the atmosphere into an area in the interior of the water line in which there is negative pressure.
Der Unterdrück in der Wasserleitung entspricht dem Gewicht der Wassersäule oberhalb des Wasserspiegels, der sich an der Austrittsstelle des Wassers aus der Wasserleitung bildet. Der größte Unterdrück ist somit zu erreichen, wenn die Einleitung der Luft im höchsten Teil der Wasserleitung erfolgt.The negative pressure in the water pipe corresponds to the weight of the water column above the water level, which forms at the point where the water emerges from the water pipe. The greatest suppression can be achieved when the air is introduced into the highest part of the water pipe.

Weitere Einzelheiten der Erfindung werden anschließend anhand der Zeichnung erläutert, welche in schematischen Querschnitt einen Großvertikalfilterbrunnen zeigt. 2 AT 000 106 UlFurther details of the invention are subsequently explained with reference to the drawing, which shows a large vertical filter well in schematic cross section. 2 AT 000 106 ul
Der dargestellte S ickerbrunnen umfaßt ein Sumpf rohr 4, welches im Bereich 3 perforiert ist und somit als Filterrohr fungiert. Das Filterrohr 3 ist von Filter-3d.es 5 umgeben, durch welchen das über die Wasserleitung 1 einströmende Wasser. in den Grundwasserkörper des Erdreichs 6 gelangt. Der Grundwasserspiegel ist mit dem Pfeil 7 angedeutet.The shown septic well comprises a sump tube 4, which is perforated in area 3 and thus acts as a filter tube. The filter tube 3 is surrounded by Filter-3d.es 5, through which the water flowing in via the water pipe 1. enters the groundwater body of soil 6. The groundwater table is indicated by arrow 7.
Om einen hinreichenden Sauerstoffgehalt im zugeführten Wasser sicherzustellen, ist eine Luftleitung 2 vorgesehen, welche durch einen Schieber 8 abschließbar ist bzw. durch den Schieber 8 mit der Atmosphäre in der Brunnenstube 9 in Verbindung gebracht werden kann. Das Ende des die Luftleitung 2 bildenden Rohres ist abgeschlossen und mit Perforationen 10 versehen. Für das Funlctionieren der Erfindung wesentlich ist das Vorliegen eines Unterdrucks im Bereich der Perforationen 10. Es wird also davon ausgegangen, daß das Wasser nicht unter Druck eingepreßt, sondern - sei es durch eine Pumpe oder durch Heberwirlcung - lediglich auf das Niveau der Perforationen 10 angehoben wird. Der auf diesem Niveau entstehende Unterdrück entspricht dann der Höhe der Wassersäule zwischen der Luftleitung 2 und dem Wasserspiegel im Sumpfrohr 4.In order to ensure a sufficient oxygen content in the supplied water, an air line 2 is provided, which can be locked by a slide 8 or can be connected to the atmosphere in the well room 9 by the slide 8. The end of the tube forming the air line 2 is closed and provided with perforations 10. The existence of a negative pressure in the area of the perforations 10 is essential for the functioning of the invention. It is therefore assumed that the water is not pressed in under pressure, but rather - whether by means of a pump or by jack lifting - only raised to the level of the perforations 10 becomes. The negative pressure which arises at this level then corresponds to the height of the water column between the air line 2 and the water level in the sump tube 4.
Die durch die Perforationen 10 (typischer Durchmesser 0,5 mm) eingeleitete Luft verteilt sich im Wasser in Form kleiner Luftbläschen. Das mit diesen Luftbläschen versehene Wasser gelangt in den Kiesfilter des Brunnens und anschließend in den Grundwasserkörper. Durch die Struktur des Kiesfilters und des Grundwasserkörpers bleiben die Luftbläschen lange im Wasser, was der Anhebung des Sauerstoffgehaltes des Anreicherungs-wassers sehr zugute kommt. Die in das Wasser einge- 3 AT 000 106 Ul tragenen Luftbläschen sollen möglichst klein sein, um • den Sauerstoffeintrag in das Wasser zu begünstigen.The air introduced through the perforations 10 (typical diameter 0.5 mm) is distributed in the water in the form of small air bubbles. The water with these air bubbles gets into the gravel filter of the well and then into the groundwater body. Due to the structure of the gravel filter and the groundwater body, the air bubbles remain in the water for a long time, which is very beneficial for increasing the oxygen content of the enrichment water. The air bubbles carried into the water should be as small as possible in order to • promote the entry of oxygen into the water.
Je höher die unterhalb der Eintrittsstelle der Luft liegende Wassersäule ist, umso größer ist der auf-tretende Unterdrück und umso leichter ist die gewünschte Sauerstoffanreicherung von etwa 3 mg/1 zu erreichen. Ein Unterdrück in der Größenordnung von 0,2 - 0,25 bar (2 - 2,5 m Wassersäule) hat sich bei Versuchen als hinreichend erwiesen. Ob es bei sehr hohen Unterdrücken durch die Belüftung zu einem Abreißen der Wassersäule kommen kann, mag dahingestellt bleiben, da jedenfalls bei Unterdrücken um 0,3 bar noch kein Anzeichen imerwünschter Betriebszustände feststellbar ist und solche Unterdrücke durchaus hinreichen, zumal der Lufteintrag selbst den Unterdrück in der Wasserleitung nur im etwa 10 % absenkt. \ 4The higher the water column below the entry point of the air, the greater the negative pressure that occurs and the easier it is to achieve the desired oxygen concentration of around 3 mg / 1. A negative pressure of the order of 0.2 - 0.25 bar (2 - 2.5 m water column) has proven to be sufficient in tests. It remains to be seen whether the water column can be torn off at very high negative pressures, because at least at 0.3 bar negative pressure there is still no sign of the desired operating conditions and such negative pressures are sufficient, especially since the air intake itself suppresses the negative pressure the water pipe only lowered by about 10%. \ 4
