Abstract

Removal of harmful substances from rainwater comprises passing it over a filter to which the substances bond and removing the water.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Entfernung von Schadstoffen aus Regenwasser, um dessen Nutzwert als Gieß­ wasser oder zum Auffüllen von Gartenteichen zu verbessern.The invention relates to a method for removing Pollutants from rainwater, for its usefulness as a pour water or to fill up garden ponds.

Die Nutzung von Regenwasser gewinnt aufgrund ständig stei­ gender Kosten für Trink- und Abwasser sowie unter Umwelt­ schutzaspekten zunehmend an Bedeutung. Vorrichtungen zum Sammeln und Nutzen von Regenwasser sind bereits in großer Zahl im Handel und erfreuen sich steigender Beliebtheit.The use of rainwater is constantly increasing due to the fact that it is steep gender costs for drinking water, wastewater and the environment protection aspects are becoming increasingly important. Devices for The collection and use of rainwater are already great Number in retail and are enjoying increasing popularity.

Ein Problem bei der Regenwassernutzung besteht darin, daß Dachrinnen und Fallrohre vorzugsweise aus Metallen, wie Kup­ fer oder Zink, hergestellt werden. Das saure Regenwasser löst beim Kontakt mit diesen Baumaterialien an deren Oberfläche Ionen heraus. Dies führt zu einer Belastung des Regenwassers mit Zink oder Kupfer, die einer Nutzung des derart gewonnenen Wassers entgegensteht.A problem with rainwater use is that Gutters and downspouts preferably made of metals such as copper fer or zinc. The acid rainwater dissolves on contact with these building materials on their surface Ions out. This leads to pollution of the rain water with zinc or copper, the use of the thus obtained Water opposes.

Zusätzlich ist Regenwasser häufig mit Luftschadstoffen, wie z. B. Ruß und Kohlenwasserstoffen belastet, die die Wasser­ qualität ebenfalls einschränken.In addition, rainwater is often polluted with air pollutants, such as e.g. B. Soot and hydrocarbons that pollute the water also limit quality.

Bei einer Nutzung des Regenwassers z. B. als Gießwasser rei­ chert sich das Kupfer im Boden und den Pflanzen an, so daß das Gießen von Nutzpflanzen mit kupferhaltigem Regenwasser nicht erfolgen sollte.When using the rainwater z. B. as irrigation water the copper accumulates in the soil and the plants, so that watering crops with copper-containing rainwater should not be done.

Die gleiche Problematik zeigt sich bei der Nutzung als Teich­ wasser mit Fischbesatz. Dort können selbst Kupfergehalte, die nur 1/10 des von der Trinkwasserverordnung zugelassenen Grenzwertes von 3 mg/L betragen, sehr leicht zu einem Fisch­ sterben führen.The same problem can be seen when used as a pond water with fish. Even copper contents can be found there only 1/10 of that permitted by the Drinking Water Ordinance  Limit of 3 mg / L, very easily to a fish die lead.

Die vorliegende Erfindung sieht vor, die Schadstoffbelastung des Regenwassers soweit zu verhindern, daß eine Regenwas­ sernutzung, z. B. als Gieß- oder Teichwasser, bedenkenlos möglich ist.The present invention provides for pollution of rainwater as far as to prevent rainwater use, e.g. B. as irrigation or pond water, without hesitation is possible.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object of the invention is achieved by Teaching of the main claim solved.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteran­ sprüchen erläutert.Advantageous embodiments of the invention are in the Unteran sayings explained.

Die Gewinnung des Regenwassers erfolgt zunächst über han­ delsübliche Fallrohrabzweige, die z. T. auch eine mechanische Vorfilterung ermöglichen. Danach wird das Wasser über ein Filtermaterial geleitet, das die Schwermetallionen bindet und damit aus dem Regenwasser entfernt. Dieses Filtermaterial muß ggf. regelmäßig erneuert oder regeneriert werden.The rainwater is initially extracted via han Standard downpipe branches, the z. T. also a mechanical Allow pre-filtering. After that, the water is over a Filter material passed, which binds the heavy metal ions and thus removed from the rainwater. This filter material must may be regularly renewed or regenerated.

Zusätzlich kann das Regenwasser mit Hilfe eines Aktivkohlefil­ ters von unpolaren Schadstoffen, wie z. B. Kohlenwasserstoffen befreit werden.In addition, the rainwater can be filtered using an activated carbon filter ters of non-polar pollutants, such as. B. hydrocarbons be freed.

Ebenso ist es möglich, das von Schadstoffen befreite Regen­ wasser mit Mineralien, Dünger oder Pflanzenschutzmitteln anzu­ reichern, um so ein auf den jeweiligen Verwendungszweck opti­ mal abgestimmtes Wasser zu erhalten.It is also possible for the rain to be freed from pollutants water with minerals, fertilizers or pesticides enrich, so as to opti for the respective purpose times to get tuned water.

Mit anderen Worten ausgedrückt wird vorgeschlagen, das Re­ genwasser vor seiner Nutzung durch ein oder mehrere Filterma­ terialien zu leiten, an denen die Schadstoffe zurückgehalten werden. In other words, it is suggested that Re backwater before it is used by one or more filter media to direct materials on which the pollutants are retained become.  

Zusätzlich kann das von Schadstoffen befreite Wasser mit Mine­ ralstoffen, Dünger oder Pflanzenschutzmitteln versetzt werden, um den Nutzwert weiter zu erhöhen.In addition, the water freed from pollutants can be refilled with a mine raw materials, fertilizers or pesticides are added, to further increase the utility value.
