Abstract
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur biologischen Reinigung von Abwaessern und kleinen Vorflutern. Formen von hoeheren Pflanzen, mit der Faehigkeit Wasser- und Abwasserinhaltsstoffe aufzunehmen, werden mittels ein- bzw. zweischichtigen brueckenartigen Traegern so mit dem Wasser in Beruehrung gebracht, dass ihre Wurzeln in das Wasser eintauchen. Die Anwendung des Verfahrens ermoeglicht eine wesentliche Senkung der Naehrstofffracht (P,N-Komponente), einen intensiven biochemischen Abbau, eine selektive Entfernung von organischen Schadstoffen des zu reinigenden Abwassers sowie eine Vorbeugung der Eutrophierung unterliegender Gewaesserabschnitte.The invention relates to a method and a device for the biological purification of waste waters and small receiving waters. Forms of higher plants, with the ability to absorb water and wastewater ingredients, are so contacted by means of one or two-layer bridge-like straps with the water that their roots dip into the water. The application of the method enables a substantial reduction of the nutrient load (P, N component), an intensive biochemical degradation, a selective removal of organic pollutants of the wastewater to be purified as well as a prevention of the eutrophication of underlying water sections.

Als geeignete Bäume sollen selektionierte Formen der Gattungen Salix, Fraxinus, BeUiIa, Populus und Alnus Verwendung finden. Unter den Sträuchern, die große Stoffwechselleistungen erbringen, sind besonders die Sambucus-Arten zu nennen. Von der Proteaceae Oritis exetsa ist bekannt, daß sie z. B. Aluminium in Holzkörpern anreichern kann, so daß die Holzasche bis 79% aus Algminiumoxid besteht.Selected trees of the genera Salix, Fraxinus, BeUiIa, Populus and Alnus are to be used as suitable trees. Among the shrubs that produce great metabolic activities, especially the Sambucus species are mentioned. From the Proteaceae Oritis exetsa is known that z. B. aluminum in wood bodies can accumulate, so that the wood ash to 79% consists of algmia.
Die Compretaceae Becium homblei reichert selektiv Kupfer an, und Hybanthus floribundus bindet hochgradig Nickel.The Compretaceae Becium homblei selectively enriches copper, and Hybanthus floribundus binds high levels of nickel.
Astragalus-Arten können selektiv Selen anreichern. Als ein- und mehrjährige Pflanzen können z. B. Heracleum giganteum und Polygonumarten Einsatz finden.Astragalus species can selectively enrich selenium. As a one- and perennial plants can z. B. Heracleum giganteum and Polygonumarten use.
Die Vorrichtung zur Durchführung des Verfahrens besteht aus einem brickenartigen Träger vorzugsweise Beton, Kunststoff oder Netz, der Keilschlitze aufweist, die dem zunehmenden Dickenwachstum der Bäume und Sträucher im Laufe der Betriebsjahre Rechnung tragen. Paßkeile dienen bei der Bepflanzung der Träger zum mechanischen Fixieren der Bäume und Sträucher bis zu einem Alter von 20 Jahren. Das sekundäre Dickenwachstum der Holzgewächse führt zu einem partiellen Festwachsen auf dem Träger. Der wachsende Baumstamm d.ückt den Paßkeil in Richtung erweiterter Schlitz, so daß das Holzgewächs ständig ausreichend stabilisiert ist.The device for carrying out the method consists of a pebble-type carrier, preferably concrete, plastic or mesh, which has wedge slots, which take into account the increasing growth of trees and shrubs during the years of operation. Pass wedges are used in the planting of the carrier for mechanical fixing of trees and shrubs up to an age of 20 years. The secondary growth of the woody plants leads to a partial growth on the carrier. The growing tree trunk depresses the registration key in the direction of the extended slot, so that the timber plant is constantly sufficiently stabilized.
Die Überbauung des Vorfluters oder Gerinnequerschnittes mittels der Träger bewirkt außerdem eine Beschattung des Gewässers und verhindert dadurch eine unerwünschte Algenmassenentwicklung durch Eutrophierungskomponenten (Stickstoff und Phosphor) sowie eine Reinigung des Wassers von de Nährstoffkomponenten während des Durchlaufens der Überbauung; so daß keine Algenmassenentwicklungen mehr auftreten können.The overbuilding of the receiving surface or channel cross-section by means of the carrier also causes a shading of the water and thereby prevents unwanted development of algae mass by Eutrophierungskomponenten (nitrogen and phosphorus) and a purification of the water of de nutrient components during the passage of the overbuilding; so that no algae mass developments can occur more.
Die Erfindung soll nachfolgend an Hand eines Beispiels erläutert werden.The invention will be explained below with reference to an example.
In einem Vorfluter mit einem mittleren Abfluß (MNQ) von 3m3/min. und einer Mineralstofffracht von 1 70ükg/d soll durch biologische Überbauung des Gewässers die Fracht auf 850kg/d gesenkt werden. Die Träger werden mit Pappeln besetzt, die abIn a receiving water with a mean discharge (MNQ) of 3m 3 / min. and a mineral load of 1 70ükg / d is to be lowered by biological overbuilding of the water the freight to 850kg / d. The porters are populated with poplars, which off
3. Betriebsjahr pro Jahr und Baum 30kg Feststoffe produzieren. Es wird mit 30% Aschegehalt gerechnet.3. Year of operation per year and tree produce 30kg of solids. It is calculated with 30% ash content.
Ein Baum entzieht also während der Wachsturnsperiode dem Vorfluter etwa 10kg Mineralstoffe, d. h. an 150 Tagen der Vegetationsperiode des Jahres werden durchschnittlich 0,07 kg Mineralstoffe pro Baum und Tag entnommen Aus den Quotienten von Fracht und Tagesleistung resultiert die Anzahl einzusetzender Bäume und Paletten. In dem Beispiel ergeben sich daraus 24685 Bäume.Thus, during the growth period, a tree removes about 10kg of minerals from the receiving waters. H. on 150 days of the growing season of the year, an average of 0.07 kg minerals per tree and day are taken from the quotients of freight and daily output resulting in the number of trees and palettes to be used. In the example this results in 24685 trees.
Claims (2)
Das Verfahren soll umweltfreundlich sein und in bezug auf die Umweltgestaltung positiv wirken.The aim of the invention is to develop a biological process for wastewater treatment or for further treatment of wastewater outside the treatment plants, which substantially lowers the nutrient (P, N) component, intensifies the biochemical degradation, which is not degraded in the biological treatment stage of the treatment plant organic Substances further reduced, inorganic pollutants (toxic heavy metals) selectively removed and prevents the eutrophication of underlying water sections.
The process should be environmentally friendly and have a positive impact on the environment.
