Description
Vorrichtung zur biologischen Reinigung von Abwässern mit Hilfe aerober Mikroorganismen Die Erfindung bezieht sich auf eine Vorrichtung zur biologischen Reinigung von Abwässer mit Hilfe aerober Mikroorganismen, bestehend aus kreisförmigen, als Bewuchsfläche für die als biologischer Rasen anwachsenden Organismen -dienenden -Platten, die nebeneinander auf einer die Kreismittelpunkte der Platten durchdringenden, antreibbaren Welle angeordnet sind und etwa zur Hälfte in ein Abwasserbecken eintauchen.Device for the biological purification of wastewater with the aid of aerobic Microorganisms The invention relates to a device for biological Purification of wastewater with the help of aerobic microorganisms, consisting of circular, as a vegetation area for the organisms growing as a biological lawn -Plates, which are next to each other on one of the circle centers of the plates penetrating, Drivable shaft are arranged and about half immersed in a sewage basin.
Diese Vorrichtung dient dazu, aerobe Mikroorganismen zur Intensivierung der Oxydation zwangsweise abwechselnd mit Luftsauerstoff und dem zu reinigenden Abwasser in Berührung zu bringen.This device is used to intensify aerobic microorganisms the oxidation is forced to alternate with atmospheric oxygen and that to be cleaned Bringing wastewater into contact.
Bekannte Tauchkörper dieser Art haben als Füllung ein Flechtwerk aus porösem, rauhem Material, die sich nach kurzer Zeit mit immer stärker werdenden Schichten aus biologischem Rasen bezieht, der bald alle Durchflußwege verstopft, so daß danach der gesamte Tauchkörper völlig verschlammt ist. Diese Anlagen können nur als schwach belastbare Anlagen mit hohem Nitratgehalt im Ablauf betrieben werden.Known immersion bodies of this type have a wickerwork filling porous, rough material, which after a short time becomes stronger and stronger Covers layers of organic turf, which soon clogs all flow paths, so that afterwards the entire immersion body is completely silted up. These plants can can only be operated as weakly resilient systems with a high nitrate content in the drain.
Eine Verschlammung der Tauchkörper beim Dauerbetrieb kann verhindert und eine erwünschte Stärke des Bewuchses auf einfache Weise eingehalten werden, wenn gemäß der Erfindung die Umdrehungsgeschwindigkeit der Platten entsprechend dem Grad der Verschmutzung des zu behandelnden Abwassers einstellbar ist, wodurch sich die Dauer der Berührung des Bewuchses mit Luft einerseits und Wasser anderseits regeln läßt.A silting up of the immersion bodies during continuous operation can be prevented and a desired thickness of the vegetation can be maintained in a simple manner, if according to the invention the speed of rotation of the plates accordingly the degree of pollution of the wastewater to be treated is adjustable, whereby the duration of the contact of the vegetation with air on the one hand and water on the other can regulate.
In vorteilhafter Ausgestaltung der Erfindung läßt sich die Umdrehungsgeschwindigkeit der Platten derart einstellen, daß eine Umdrehung in weniger als zwei Minuten erfolgt.In an advantageous embodiment of the invention, the speed of rotation Adjust the plates so that one rotation takes less than two minutes.
Bei einer Vorrichtung mit einer oberhalb des zu reinigenden Abwassers gelagerten Welle kann ferner der Zwischenraum zwischen zwei benachbarten, vorzugsweise aus Asbestzement hergestellten Platten mit rauher und/oder poröser Oberfläche größer sein als die Dicke der Platten.In a device with one above the wastewater to be cleaned supported shaft can also be the space between two adjacent, preferably Panels made from asbestos cement with a rough and / or porous surface are larger be than the thickness of the panels.
Besonders zweckmäßig ist es, jeweils zwischen zwei benachbarten Platten Rechenstäbe anzuordnen, die den an den Platten angesetzten biologischen Rasen überschüssiger Stärke während der Umdrehung abstreifen.It is particularly useful between two adjacent plates Arrange rake bars that excess the biological lawn attached to the plates Strip off starch while turning.
Die Erfindung wird an Hand des in der Zeichnung dargestellten Ausführungsbeispiels erläutert. Es zeigt F i g. 1 einen Grundriß einer erfindungsgemäßen Vorrichtung, die Tauchkörperanlage genannt wird, F i g. 2 einen Schnitt nach dem Linienzug 1-I in F i g. 2, F i g. 3 einen Schnitt nach der Linie II-II in F i g. 2 und F i g. 4 eine schematische Darstellung mehrerer hintereinander angeordneter Abwasserbecken.The invention is based on the embodiment shown in the drawing explained. It shows F i g. 1 is a plan view of a device according to the invention, the immersion body system is called, F i g. 2 shows a section along the line 1-I in Fig. 2, fig. 3 shows a section along the line II-II in FIG. 2 and F i g. 4 a schematic representation of several wastewater basins arranged one behind the other.
Die in der Zeichnung dargestellte Vorrichtung zur biologischen Reinigung von Abwässern besteht aus kreisförmigen, als Bewuchsfläche für biologischen Rasen dienenden dünnen Platten 1, die aus Asbestzement hergestellt und auf einer Welle sitzend zusammen mit dieser über mit einem Zulauf A und einem Ablauf B versehenen Abwasserbecken so angeordnet sind, daß sie etwa zur Hälfte in das Abwasserbecken eintauchen.The device for biological cleaning shown in the drawing of sewage consists of circular, as a vegetation area for biological lawn serving thin plates 1 made of asbestos cement and mounted on a shaft sitting together with this one provided with an inlet A and an outlet B. Sewer basins are arranged so that they are about halfway into the sewer basin immerse.
Die Welle wird von zwei Lagern getragen, die auf dem Beckenrand aufsitzen.The shaft is carried by two bearings that sit on the edge of the pool.
Die Welle und damit die Platten werden von einem Motor 3 über ein Getriebe langsam in eine solche Umdrehung versetzt, daß jede Platte in zwei Minuten etwa einmal umläuft. Die Umdrehungsrichtung der Platten ist so, daß sich ihr in das Abwasser eintauchender Teil der Strömungsrichtung des Abwassers entgegenbewegt, wie in F i g. 3 mit einem Pfeil auf der vorn liegenden Platte angedeutet ist.The shaft and thus the plates are driven by a motor 3 via a Gear slowly rotated in such a way that each plate in two minutes revolves around once. The direction of rotation of the plates is such that you are in the submerged part of the wastewater moves in the opposite direction to the flow of the wastewater, as in Fig. 3 is indicated by an arrow on the plate in front.
Die Umdrehungsrichtung kann aber auch umgekehrt sein.However, the direction of rotation can also be reversed.
Wie das in F i g. 4 dargestellte Schema zeigt, können mehrere Abwasserbecken so hintereinandergeschaltet werden, daß sie nacheinander in einer Richtung durchströmt werden. Die Welle ist dabei quer zur Strömungsrichtung angeordnet. Den einzelnen Becken kann, wie in F i g. 4 bei dem zweiten, dritten und vierten Becken dargestellt ist, zusätzlich Abwasser in Längsrichtung der Welle zugeführt werden.As shown in FIG. 4 shows, several sewage basins can be used be connected in series so that it flows through one after the other in one direction will. The shaft is arranged transversely to the direction of flow. The single Basin can, as shown in FIG. 4 shown in the second, third and fourth basin is, wastewater is also fed in the longitudinal direction of the shaft.
