Description

Die Erfindung betrifft ein Aufzuchtbecken für Wasserlebewesen gemäß Patent 10 2007 002 584.1, insbesondere zu Intensiv-Fischmast, aufweisend eine Vorrichtung zur Sedimentabsaugung, Grobsiebung, Flotation, Sedimentation, Nitrifikation und Denitrifikation.The invention relates to a rearing tank for aquatic organisms according to patent 10 2007 002 584.1, in particular to intensive fishmast, comprising a device for sediment extraction, coarse screening, flotation, sedimentation, nitrification and denitrification.

Wie dem vorerwähnten Patent zu entnehmen ist, bezieht sich die Erfindung auf vorgefertigte Aufzuchtbecken in rechteckiger Bauweise. Bei größerem Wasservolumen stößt die rechteckige Bauweise jedoch statisch an Grenzen.As can be seen from the aforementioned patent, the invention relates to prefabricated rearing tanks of rectangular construction. With a larger volume of water, however, the rectangular construction is statically pushed to its limits.

Die Aufgabe der vorliegenden Erfindung besteht darin, die bekannte Vorrichtung zur Wasseraufbereitung derart weiterzuentwickeln, dass eine weitaus bessere Statik gewährleistet ist.The object of the present invention is to develop the known device for water treatment in such a way that a much better statics is guaranteed.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, indem das Nitrifikationsmodul unmittelbar im runden Becken über dem Radius des Rundbeckens angeordnet ist, wobei eine gleichmäßige Strömung in Aufzuchtbecken erzeugt wird.The object according to the invention is achieved by arranging the nitrification module directly in the round basin above the radius of the round basin, whereby a uniform flow is generated in the breeding basin.

Neben der eigentlichen Nitrifikation wird gleichzeitig das Produktionswasser im Becken (1) stark in Strömung (2) versetzt. In der Mitte des Rundbeckens befindet sich unmittelbar über dem Beckengrund ein Sedimentabsauger (3), der über ein Rohr (10) zum Beckenrand führt. Am Beckenrand befindet sich ein getauchter Hohlkörper (9), der bewirkt, dass durch den hydrostatischen Druck ein Saugeffekt über die Rohrverbindung in der Beckenmitte entsteht. Mit diesem Saugeffekt wird das Sediment in der Beckenbodenmitte entfernt und zum Beckenrand verfrachtet. Am Beckenrand erfolgt eine Grobsiebung mittels Spalt- oder Bogensieb (9), wobei das Siebgut manuell entfernt wird. Das vor gesiebte Rohwasser gelangt über einen Bypass (5) in eine Flotationsvorrichtung (8) und wird dort erneut einer mechanischen Reinigung unterzogen. Danach gelang das Rohwasser – dem langsamen Bypassverlauf (5) folgend – in eine Sedimentation (7) unter Zuhilfenahme von Schrägklärern. In diesem sehr beruhigten und anaeroben Modul findet die Denitrifikation zum Abbau des Nitrates zu Stickstoff statt. Ab hier verläuft das gesamte Klärverfahren (6) genauso wie in der vorerwähnten Patentanmeldung beschrieben. Daher erübrigt sich eine weitere Vertiefung.In addition to the actual nitrification, the production water in the basin ( 1 ) strongly in flow ( 2 ). In the middle of the round basin is located directly above the pool bottom a sediment extractor ( 3 ), which has a pipe ( 10 ) leads to the edge of the pool. At the pool edge is a submerged hollow body ( 9 ), which causes the hydrostatic pressure to create a suction effect via the pipe connection in the middle of the pool. With this suction effect, the sediment in the middle of the pelvic floor is removed and transported to the edge of the pool. At the edge of the pool, coarse screening is carried out by means of a gap or arc sieve ( 9 ), whereby the screenings are removed manually. The pre-screened raw water passes through a bypass ( 5 ) into a flotation device ( 8th ) and is again subjected to a mechanical cleaning. Then the raw water - the slow bypass course ( 5 ) - into sedimentation ( 7 ) with the help of diagonal clarifiers. In this very soothing and anaerobic module, denitrification takes place to degrade the nitrate to nitrogen. From here, the entire purification process ( 6 ) as well as in the aforementioned patent application. Therefore, a further depression is unnecessary.

Die Erfindung wird anhand der beigefügten Zeichnung (1) näher erläutert.The invention will be described with reference to the attached drawing ( 1 ) explained in more detail.
