Description

Verfahren zur biologischen Reinigung von Wasser und Abwasser in einem mit mechanisch erzeugter Wasserumwälzung und Druckluft arbeitenden Lüftungsbecken.Process for the biological purification of water and waste water in one with mechanically generated water circulation and compressed air working ventilation basin.

Es ist bekannt, daß Abwasser duych - Belüftung gereinigt werden kann. In Dentschland nennt man dieses Klärverfahren Schlammbelebungsverfahnen. Das Verfahren wird in zwei grundsätzlich verschiedenen Formen angewandt, die sich darin unterscheiden, daß in einem Fall künstlich erzeugte Preßluft zur Belüftung verwendet wird, während in dem andern Fall es sich um reine Oberflächenbelüftung handelt. Bei der Oberflächenbelüftung wird das Wasser mit mechanischen Einrichtungen, wie Paddel, Rührwerke u. dgl., umgewälzt, so daß die sich dadurch ständig erneuernde Wasseroberfläche Sauerstoff aus der atmosphärischen Luft aufnimmt. Dieses Verfahren hat gegenüber dem Preßluftverfahren den Nachteil, daß die Reinigung des Abwassers bedeutend mehr Zeit beansprucht, weil die Sauerstoffaufnakne an der Wasseroberfläche unvollkommen ist. Nach der vorliegenden Erfindung soll dieser Nachteil durch Einführung von Zusatzpreßluft ausgeglichen und diese an einer Stelle eingeführt werden, wo der senkrecht aufwärts gerichtete natürliche Auftrieb der Luftblasen der Umwälzungsströmung des Wassers lentgegenläuft, damit die Luftblasen ganz oder teilweise durch den Wasserstrom abgelenkt und gezwungen werden, einen weiteren Weg zur Wasseroberfläche zu nehmen. Auf diese Weise bleibt die Luft länger mit dem Wasser in Berührung. It is known that sewage can be cleaned duych - aeration. In Dentschland, this treatment process is called sludge revitalization. The procedure is used in two fundamentally different forms, which differ in that in one case artificially generated compressed air is used for ventilation, while in the other case it is pure surface ventilation. In surface ventilation the water is circulated with mechanical devices such as paddles, agitators, etc., so that the constantly renewing water surface oxygen from the atmospheric Absorbs air. This process has the disadvantage compared to the compressed air process that the cleaning of the sewage takes significantly more time, because the oxygen absorption is imperfect at the surface of the water. According to the present invention this should Disadvantage compensated by the introduction of additional compressed air and this in one place are introduced where the upward vertical natural buoyancy of the Air bubbles counteract the circulating flow of the water so that the air bubbles flow be diverted entirely or partially by the flow of water and forced to a to take another way to the surface of the water. This way the air stays longer in contact with the water.

Eine Anwendungsmöglichkeit des Verfahrens ist auf beiliegender Zeichnung dargestellt. Hierin bedeutet a das Becken, das von dem zu behandelnden Wasser oder Abwasser ständig oder mit Unterbrechungen durchflossen wird; b ist eine in der Längsrichtung des Beckens angebrachte, mit Flügeln c versehene, sich in der Pfeilrichtung drehende Welle; bei d wird fein verteilte atmosphärische Luft durch Filterplatten, gelochte Rohre oder andere poröse Einrichtungen eingepreßt. One possible application of the process is shown in the accompanying drawing shown. Herein, a means the basin, that of the water to be treated or Wastewater is flowing through continuously or intermittently; b is one in the longitudinal direction attached to the pelvis, provided with wings c, rotating in the direction of the arrow Wave; At d, finely divided atmospheric air is perforated through filter plates Pipes or other porous devices pressed in.

Durch Drehung der Welleb in der Pfeilrichtung wird der Inhalt des Beckens ebenfalls in der Pfeilrichtung in Bewegung gesetzt, d. h. umgewälzt. Der Umw,älzungsstrom nimmt die bei d eingepreßte Luft auf, so daß sie an dem unmittelbaren Entweichen in senkrechter Richtung verhindert wird. Außerdem wird die Luft von den an den Flügeln c befestigten Schaufeln c' mitgenommen. Zur weiteren Unterstützung der innigen Mischung des Beckeninhaltes mit der eingeführten Luft können ferner die Flügel aus siebartigem Material bestehen Auf diese Weise wird erreicht, daß die - Luftbläschen längere Zeit mit dem Beckeninhalt' in Berührung bleiben, wodurch die Sauerstoffaufuahme besonders giinstig unterstützt wird. By rotating the shaft b in the direction of the arrow, the content of the Pelvis is also set in motion in the direction of the arrow, d. H. circulated. Of the Circulating flow absorbs the air injected at d, so that it passes to the immediate Escape in the vertical direction is prevented. In addition, the air from the vanes c 'attached to the blades c are taken along. For further assistance the intimate mixing of the basin contents with the introduced air can also the wings consist of sieve-like material In this way it is achieved that the - air bubbles remain in contact with the pelvic contents for a longer period of time, as a result of which the oxygen uptake is particularly favorably supported.

An Stelle der atmosphärischen Luft können naturgemäß reiner Sauerstoff oder Sauerstoff enthaltende Gase oder Flüssigkeiten verwendet werden. Naturally, pure oxygen can take the place of atmospheric air or gases or liquids containing oxygen can be used.

Die Einführungsstelled kann ebenfalls beliebig angeordnet werden. Ebenso können die Flügel c beliebige, z. B. schaufelartige Formen haben, und die Welle b kann sowohl zentrisch wie exzentrisch oder auch quer zur Längsrichtung der Becken liegen. The insertion point can also be arranged in any way. Likewise, the wings can c any, z. B. have shovel-like shapes, and the Wave b can be either centric or eccentric or transverse to the longitudinal direction of the Pelvis.
