Abstract

The invention relates to a filter arrangement for aquariums, biotopes, swimming pools or similar and for sewage pre-treatment, which comprises distinct aerobic and anaerobic regions, separated from each other in filter chambers. Within the filter material, regions of varying flow resistance are provided for the formation of said regions. Aerobic and anaerobic regions, thus, form in the filter material, due to the resulting differing oxygen supplies, which guarantees a complete elimination of organic material and harmful substances.

Description

Filteranordnung für Aquarien, Biotope, Schwimmbecken oder dergleichen und zur Ab asseraufbereitung Filter arrangement for aquariums, biotopes, swimming pools or the like and for water treatment
Die vorliegende Erfindung bezieht sich auf eine Filteranordnung, insbesondere einen Bio-Filter für Aquarien, Biotope, Schwimmteiche, Schwimmbecken oder dergleichen und zur Abwas- seraufbreitung, bei der das zu reinigende Wasser durch ein Filtersubstrat hindurchgesaugt und in die Gesamtwassermenge zurückgeführt wird.The present invention relates to a filter arrangement, in particular a bio-filter for aquariums, biotopes, swimming ponds, swimming pools or the like and for wastewater treatment, in which the water to be cleaned is sucked through a filter substrate and returned to the total amount of water.
Die Aufgabe einer vollständigen biologischen Wasseraufbereitung wird von den meisten Filteranordnungen, beispielsweise Aquarienfiltern, Schwimmbadfiltern und dergleichen, nur unzu- reichend erfüllt.Most filter arrangements, for example aquarium filters, swimming pool filters and the like, only insufficiently fulfill the task of a complete biological water treatment.
Der Abbau von organischen Substanzen - Proteine zu Pepti- den, Aminosäuren, Ammoniak, Nitrit, Nitrat und letztendlich Stickstoff; Peptide zu Carbonsäuren, Wasser und Kohlendioxid und so weiter erfolgt nur lückenhaft, weil die entsprechenden Aufgaben nur von einer Vielzahl von Bakterienstämmen erfüllt werden können, die unterschiedliche Lebensbedingungen benötigen.The breakdown of organic substances - proteins to peptides, amino acids, ammonia, nitrite, nitrate and ultimately nitrogen; Peptides to carboxylic acids, water and carbon dioxide and so on are only incomplete because the corresponding tasks can only be performed by a large number of bacterial strains that require different living conditions.
Von den Mikroorganismen werden unterschiedliche Substrate als Siedlungsgebiet bevorzugt. Entscheidend für den Aufbau einer lückenlosen Kette von Bakterienstämmen, die den Abbau organischer Substanzen zu unschädlichen Gasen bewirken, ist jedoch nicht nur das Anbieten unterschiedlicher Substrate, sondern auch die Schaffung von aeroben und anaeroben Bedingungen, ohne die die Abbaukette be- reits bei Nitrat und Nitrit endet.Different substrates are preferred as settlement areas by the microorganisms. Decisive for building a complete chain of bacterial strains that break down organic substances into harmless gases is not only the offering of different substrates, but also the creation of aerobic and anaerobic conditions, without which the breakdown chain is already available for nitrate and nitrite ends.
Nur in einem sauerstoffarmen Milieu sind die Mikroorganismen gezwungen, den benötigten Sauerstoff aus Stickstoffverbin- dungen und nicht aus dem Wasser zu beziehen. Die Anordnung oder Installierung eines Bypaß-Filters ist somit unerläßlich, wenn das Wasser nicht mechanisch und biologisch nur unvollständig aufbereitet werden soll.The microorganisms are only forced to obtain the required oxygen from nitrogen compounds and not from water in a low-oxygen environment. The arrangement or installation of a bypass filter is therefore essential if the water is not to be treated mechanically and biologically incompletely.
Es ist somit Aufgabe der vorliegenden Erfindung, eine Filteranordnung der eingangs genannten Gattung zu schaffen, die eine vollständige biologische Wasseraufbereitung gewährlei- stet. Diese Aufgabe wirα erfmdungsgemaß durch die m den An¬ sprüchen gekennzeichnete Filteranordnung gelost.It is therefore an object of the present invention to provide a filter arrangement of the type mentioned at the outset, which ensures complete biological water treatment. This task erfmdungsgemaß wirα achieved by the m the on ¬ sayings marked filter assembly.
Die erfmdungsgemaße Filteranordnung lost die Aufgabe ei¬ ner vollständigen biologischen Wasseraufbereitung einfacher Weise:The erfmdungsgemaße filter assembly lost the task ei ¬ ner complete biological treatment of a simple way:
- mechanischer Schnellfllter für grobe Schwebstoffe, aerober und anaerober Filter als Lebensraum für Mikroorganismen;- Mechanical quick filter for coarse suspended matter, aerobic and anaerobic filter as a habitat for microorganisms;
- Filtersubstrate aus Kohle oder Form von Molekularsie- ben zwecks Erhöhung des lonenaustausches und Bindung toxischer Substanzen.- Filter substrates made of coal or in the form of molecular sieves in order to increase the ion exchange and bind toxic substances.
In den angeschlossenen Zeichnungen ist die erf dungsgemäße Filteranordnung anhand eines Aquarienfllters beispielhaft veranschaulicht. Darm zeigtIn the attached drawings, the filter arrangement according to the invention is exemplified using an aquarium filter. Intestine shows
Fig. 1 eine Filterruckwand eines Aquariums axonometπ- scher Darstellung, wahrend die Figuren 2 und 3 unterschiedliche Ausfuhrungsformen der Filteranordnung der Draufsicht zeigen.Fig. 1 shows a filter back wall of an aquarium axonomic representation, while Figures 2 and 3 show different embodiments of the filter arrangement of the top view.
Das Wasser (Fig. 1) wird von der Pumpe durch das Ansauggitter 2 in die Vorkammer 3 und den Vorfilter 4 gesaugt, pas- siert das Filtergitter 5, das mit der Filterruckwand 6, die auch durch die Aquaπenruckwand gebildet sein kann, und der Frontplatte 7 die erste Filterkammer 8 mit rechteckigem Querschnitt bildet.The water (Fig. 1) is sucked by the pump through the suction grille 2 into the pre-chamber 3 and the pre-filter 4, passes through the filter grille 5, which with the filter back wall 6, which can also be formed by the water back pressure wall, and the front plate 7 forms the first filter chamber 8 with a rectangular cross section.
Durch den Filtersack 9 mit rundem Querschnitt entstehen im Filtermateπal 10, durch vom Rand zur Mitte zunehmenden Stromungswiderstand, verschiedene Stromungsgeschwindigkeiten, so daß sich zum Zentrum der Filtersubstrate 10 anaerobe Bedingungen trotz hohem Durchfluß einstellen. Folglich kann der Filter schnell grobe Schwebstoffe entfernen und trotzdem wie ein sehr langsam laufender Bypaß-Filter wirken.Due to the filter bag 9 with a round cross-section, various flow velocities arise in the filter material 10, due to increasing flow resistance from the edge to the center, so that anaerobic conditions occur despite the high flow rate to the center of the filter substrates 10. As a result, the filter can quickly remove coarse suspended matter and still act like a very slow-running bypass filter.
Der nach oben offene Filter erleichtert konstruktionsbedingt das Auswechseln des Filtermateπals 10 und ermöglicht das Ausgasen einfacher Weise. Der Filter kann so innerhalb weniger Minuten seinen spezifischen Aufgaben angepaßt werden. Der Filter bildet mit der Frontplatte 7 die Aquaπenruck- wand und es können alle notwendigen Aggregate für den Betrieb des Aquariums, wie z.B. Heizstab, für den Betrachter unsichtbar angebracht werden. Die Abdichturg zur Aquarienseitenwand (Fig. 1 und 2) er¬ folgt durch eine verstellbare U-Schiene 11. Dadurch wird ein spaltfreies Anpassen des Filters an die Aquarienseitenwand er¬ reicht, so daß aas Eindringen von Aquarienbewohnern den Filterbereich verhindert wird.The filter, which is open at the top, facilitates the replacement of the filter material 10 by design and enables outgassing in a simple manner. The filter can thus be adapted to its specific tasks within a few minutes. The filter forms with the front panel 7 the aqua pressure wall and all the necessary units for the operation of the aquarium, such as a heating element, can be attached invisibly to the viewer. The Abdichturg the aquarium side wall (Figs. 1 and 2) it follows ¬ 11 by an adjustable U-rail Thereby, a gap-free adjusting ranges of the filter to the aquarium side wall he ¬ so that aas penetration of aquariums occupants is prevented the filter area.
Die Anpassung an die Aquarienseitenwand kann auch durch ein Schragstellen des Ansauggitters 2 erreicht werden.The adaptation to the aquarium side wall can also be achieved by tilting the intake grille 2.
Eine weitere Möglichkeit zur Schaffung unterschiedlicher Stromungsverhaltnisse im Filtersubstrat 10 ist das Einbringen von Filtermaterial von geringer Dichte 12, dessen Kern sich ein Substrat höherer Dichte 13 (Fig. 2) befindet.Another possibility for creating different flow conditions in the filter substrate 10 is the introduction of filter material of low density 12, the core of which is a substrate of higher density 13 (FIG. 2).
Wird die Filterruckwand auf ein Bodengitter 14 gestellt, wirkt die Filterruckwand auch als Bodendurchfluter, da der durch die Pumpe 1 erzeugte Unterdruck auch einen Teilstrom des Wassers durch den Bodengrund saugt.If the filter back wall is placed on a floor grid 14, the filter back wall also acts as a floor flood, since the vacuum generated by the pump 1 also sucks a partial flow of the water through the bed.
In identischer Weise kann die erfmdungsgemäße Filteran¬ ordnung auch m Biotopen, Schwimmbecken, Schwimmteichen, Teichen und m Fließgewassern eingesetzt werden und durch biolo¬ gische Aufbereitung des Wassers den Einsatz von Chemikalien überflüssig machen.Identically The inventive Filteran ¬ can order also m biotopes, swimming pools, swimming ponds, ponds and m Fließgewassern be used, making unnecessary the use of chemicals by biolo ¬ cal treatment of the water.
In diesem Zusammenhang hat sich Steinwolle als Filtermaterial besonders bewahrt, einerseits durch die feinfaserige Struktur und die dadurch bedingte große Oberflache, andererseits durch die leichte Komprimierbarkeit , wodurch die be- schπebenen Zonen unterschiedlicher Dichte erreichbar sind. Steinwolle stellt auch ein ideales Wurzelsubstrat für Wasserpflanzen dar, da keine zusatzlichen Nährstoffe m das Wasser eingebracht werden.In this context, rock wool has proven to be particularly useful as a filter material, on the one hand due to the fine-fiber structure and the large surface area resulting from it, and on the other hand due to its easy compressibility, which means that the zones with different densities can be reached. Rock wool is also an ideal root substrate for aquatic plants, since no additional nutrients are introduced into the water.
Die erfmdungsgemäße Filteranordnung laßt sich leicht m die Randzone bestehender Teiche einbringen, wobei sie als Teil der Uferzone oder auch als Rmgleitung ausgeführt sein kann. Zweckmäßig werden dabei einem lockeren Pflanzsubstrat um ein Dra agerohr herum Filtersubstrate höherer Dichte angeordnet. In das Dramagerohr ist ein Innenrohr mit Bohrungen em- gefuhrt, um eine gleichmaßige Saugwirkung der Pumpe zu gewahrleisten. Überdies kann die erf dungsgemaße Filteranordnung im Schwerkraft- oder Saugbetrieb arbeiten, so daß keine Tiere oder Zoo- oder Phytoplankton die Pumpe gelangen und dort zerstört werden. Wie bereits erwähnt, hat sich Steinwolle als Filtermaten- al besonders bewahrt. Trotz der leichten Komprimierbarkeit zur Ausbildung von Zonen unterschiedlicher Dichte ist dieses Mate¬ rial nicht bmdig, so daß immer eine gewissen Flussigkeits- durchlassigkeit gegeben ist.The filter arrangement according to the invention can easily be introduced into the edge zone of existing ponds, it being possible for it to be designed as part of the bank zone or as an umbilical. In this case, filter substrates of higher density are expediently arranged around a drain pipe around a loose plant substrate. An inner tube with holes is inserted into the drama tube to ensure a uniform suction effect of the pump. In addition, the filter arrangement according to the invention can work in gravity or suction mode, so that no animals or zoo or phytoplankton get into the pump and are destroyed there. As already mentioned, rock wool has been particularly well-preserved as a filter material. Despite the slight compressibility of the formation of zones of different density of this mate rial is not ¬ bmdig, so that always a certain Flussigkeits- is given permeability.
Eine weitere Anwendung der erfmdungsgemaßen Filteranord¬ nung besteht darin, umweltschadliche Substanzen aus einem Was¬ serkreislauf auszuschleusen (beispielsweise Schwermetalle, Hormone oder hormonahnliche Moleküle) . Weiterhin eignet sich die erfmdungsgemaße Filteranordnung auch zur Behandlung von Fließgewassern, indem die erf dungsgemaßen Filterelemente einfach m die Strömung eingehängt werden. Another application of the inventive Filteranord ¬ voltage is umweltschadliche substances from a water circuit auszuschleusen What ¬ (for example, heavy metals, hormones or hormonahnliche molecules). Furthermore, the filter arrangement according to the invention is also suitable for the treatment of flowing waters, in that the filter elements according to the invention are simply suspended in the flow.
