Abstract
Description
Die Erfindung betrifft einen Überdruck-Wirbel-Reaktor mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an overpressure vortex reactor with the Features of the preamble of claim 1.
Der Erfindung liegen folgende Aufgaben zugrunde.The invention is based on the following objects.
- - hoher Sauerstoffeintrag und Veratmungsaktivität,- high oxygen input and breathing activity,
- - minimale Energiezufuhr,- minimal energy input,
- - geringer Platzbedarf,- little need for space,
- - universeller Einsatz in bezug auf Reaktion bzw. Bauvolumen.- Universal use in terms of reaction or construction volume.
Die Aufgabe wird nach heutigem Stand der Technik durch aufwendige Konstruktion gelöst. Aus technischen und verfahrenstechnischen Gründen müssen das Reaktions- und Bauvolumen klein gehalten werden. Dies beinhaltet hohe Investitionen und Betriebskosten. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge stellt und wird nachfolgend näher erläutert:According to the current state of the art, the task is complicated Construction solved. From technical and procedural For reasons the reaction and construction volume must be kept small will. This includes high investments and operating costs. An embodiment of the invention is shown in the drawing provides and is explained in more detail below:
In einem Überdruck-Wirbel-Reaktor wird organisch belastetes Abwasser durch aktivierte Mikroorganismen gereinigt.In an overpressure vortex reactor, organically contaminated Wastewater cleaned by activated microorganisms.
Der Überdruck-Wirbel-Reaktor (Fig. 1) besteht aus einem zylindri schen (1), in dem ein Gemisch aus Abwasser, Rücklaufschlamm und Luft (nachfolgend Gemisch genannt) ständig in Rotation gehalten wird.The positive pressure vortex reactor ( Fig. 1) consists of a cylindri's ( 1 ) in which a mixture of waste water, return sludge and air (hereinafter called mixture) is kept in rotation.
Durch die Rotation des Gemisches und auch mit Hilfe von Überdruck wird verhindert, daß sich die Bakterienagglomerate und Luftbläs chen vergrößern, was zu einem außergewöhnlich hohen Sauerstoff eintrag und einer hohen Veratmungsaktivität führt.Through the rotation of the mixture and also with the help of overpressure prevents the bacterial agglomerates and air bubbles Chen enlarge, resulting in exceptionally high oxygen entry and high breathing activity.
Für die Rotation des Gemisches sorgt eine spezielle Wirbel-Düse, die im unteren Bereich des Überdruck-Wirbel-Reaktors tangential eingeführt wird (Fig. 2) und deren primäre Aufgabe darin besteht, die Bakterienagglomerate im Rücklaufschlamm zu zerkleinern und die Luftzufuhr in Form feinster Luftbläschen zu gestalten.The rotation of the mixture is ensured by a special vortex nozzle, which is introduced tangentially in the lower area of the overpressure vortex reactor ( Fig. 2) and whose primary task is to crush the bacterial agglomerates in the return sludge and the air supply in the form of the finest air bubbles to design.
