Abstract
Description
Unter Nitrifikation wird bekanntlich eine Oxydation des durch Zersetzung von stickstoffhaltigen biologischen Substanzen freiwerdenden Ammoniaks zu Nitrat mit Hilfe von aeroben sog. nitrifizierenden Bakterien (Nitrifikanten) verstanden.As is known, nitrification is an oxidation of the by Decomposition of nitrogenous biological substances released ammonia to nitrate with the help of aerobic so-called understood nitrifying bacteria (nitrifying bacteria).
Eine derartige Nitrifikation tritt daher nur auf, wenn Sauerstoffüberschuß vorhanden ist.Such nitrification therefore only occurs if Excess oxygen is present.
Unter Denitrifikation wird die Umwandlung der durch Nitrifikation entstandenen Nitrate in Stickoxyd oder freien Stickstoff mit Hilfe spezieller Bakterien verstanden, und die nur vor sich gehen kann, wenn Sauerstoffmangel herrscht, weil dann die Mikroorganismen das Bestreben haben, den im Nitrat enthaltenen Sauerstoff aufzunehmen und dabei den Stickstoff abzuspalten, wodurch eine Reinigung des Abwassers zustandekommt.Denitrification is the conversion of the Nitrification created nitrates in nitrogen oxide or free Understand nitrogen with the help of special bacteria, and the can only happen if there is a lack of oxygen because then the microorganisms endeavor that in the nitrate contained oxygen and thereby the nitrogen split off, thereby purifying the waste water comes about.
Um beide Verfahren ordnungsgemäß durchführen zu können, ist es bekannt, mit zwei Becken zu arbeiten, wobei in dem ersten Becken die Nitrifikation stattfindet, während in dem zweiten Becken die Denitrifikation vor sich geht, wobei jedoch auch in dem Denitrifikationsbecken Abwasser zugeführt werden muß, damit die für die Durchführung der Denitrifikation notwendigen Mikroorganismen vorhanden sind.To be able to carry out both procedures properly, is it is known to work with two basins, being in the first Basin nitrification takes place while in the second Basin denitrification is going on, but so is wastewater must be supplied in the denitrification tank, thus the one for carrying out denitrification necessary microorganisms are present.
Da bei Nitrifikation mit Sauerstoffüberschuß, hingegen bei Denitrifikation mit Sauerstoffmangel, gearbeitet werden muß, war es bisher nicht möglich, diese Vorgänge in einem einzigen Teich durchzuführen.As with nitrification with an excess of oxygen, however, with Denitrification with lack of oxygen, must be worked So far it has not been possible to do these operations in one Pond.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Teichkläranlage zur Reinigung von Abwasser mit Nitrifikation und Denitrifikation zu schaffen, in welcher die biochemischen Vorgänge, die bei der Nitrifikation und auch bei der Denitrifikation vor sich gehen, in einem Teich durchgeführt werden.The invention is therefore based on the object Pond treatment plant for the purification of waste water with nitrification and to create denitrification in which the biochemical Processes involved in nitrification and also in Denitrification is going on, done in a pond will.
Das wird erfindungsgemäß dadurch erreicht, daß in dem mit Abwasser beaufschlagten Teich bevorzugt zentrisch ein belüftetes Haufwerk aus Ansiedelflächen, z.B. Tauchkörpern, Tropfkörpern oder dergleichen, für Mikroorganismen (Nitrifikanten) vorgesehen ist, und daß die Teichzone und auch der Teichrand weitab vom belüfteten Haufwerk als sauerstoffarme Belebtenschlammzone durch Ruhigwasser ausgebildet ist, die als Denitrifikationszone dient.This is achieved according to the invention in that with Wastewater loaded pond is preferably centric ventilated pile from settlement areas, e.g. Immersion bodies, Trickling filters or the like, for microorganisms (Nitrifying) is provided, and that the pond zone and also the edge of the pond far from the ventilated heap as Low-oxygen activated sludge zone through calm water is formed, which serves as a denitrification zone.
Dabei kann das Haufwerk aus Ansiedelflächen in einer Umhüllung oder Vertiefung, z.B. einem Kanal oder einer Wanne, untergebracht sein und eine Belüftungseinrichtung vorgesehen sein.The pile of settlement areas in one Envelope or recess, e.g. a canal or a tub, be housed and a ventilation device be provided.
Bei diesem Verfahren wird das vorgerechte Abwasser dem Teich zugeführt, in welchem es dann in das belüftete Haufwerk aus Ansiedelflächen gelangt, in welchem eine Belüftung stattfindet, welche eine Nitrifikation, d.h. eine Nitratbildung, zur Folge hat. Diese Nitrate gelangen durch die Umwälzung des Wassers in die Ruhigwasserzone also in die Teichsohle und den Teichrand, in der Sauerstoffmangel herrscht und sich eine sauerstoffarme Belebtenschlammzone ausbildet, so daß dort die Denitrifikation stattfinden kann, d.h. die Abspaltung des Stickstoffes durch die Mikroorganismen, wobei sie zugleich den Sauerstoff aus dem Nitrat aufnehmen. In this process, the pre-fair wastewater is transferred to the pond fed, in which it is then in the ventilated pile Settling areas in which there is ventilation takes place, which is a nitrification, i.e. a Nitrate formation. These nitrates get through the circulation of the water in the calm water zone so in the Pond bottom and the pond edge, in the lack of oxygen and there is a low oxygen activated sludge zone trains so that denitrification can take place there, i.e. the nitrogen is split off by the Microorganisms, which also remove the oxygen from the Take up nitrate.
Diese Teichkläranlage zeichnet sich vor allen Dingen dadurch aus, daß die technischen Aufwendungen denkbar gering sind. Abgesehen von einer Belüftungseinrichtung sind keine weiteren Becken und auch keine weiteren Einrichtungen erforderlich, wie z.B. Pumpen, Rückführrohre, Umwälzeinrichtungen und dergleichen, wie sie bei Reinigungsverfahren mit Belebtenschlammbecken sonst erforderlich sind.This pond sewage treatment plant is characterized above all from that the technical expenditure is very low. Apart from one ventilation device, there are no others Pools and no other facilities required, such as. Pumps, return pipes, circulators and the same as with cleaning processes Busy sludge pools are otherwise required.
In der Zeichnung ist schematisch die erfindungsgemäße Teichkläranlage dargestellt.In the drawing, the invention is schematically Pond treatment plant shown.
Mit 1 ist das Teichbecken bezeichnet, das im Querschnitt dargestellt ist. Zentrisch ist mit 2 ein Kanal bezeichnet, der ein Haufwerk 4 aus Ansiedelflächen, z.B. Tauchkörpern, für Mikroorganismen aufweist. Mit 3 ist eine Belüftungseinrichtung bezeichnet, die den Sauerstoffüberschuß für die Durchführung der Nitrifikation liefert.With 1 the pond pool is designated, which is shown in cross section. Centrally designated 2 is a channel which has a heap 4 of settling areas, for example immersion bodies, for microorganisms. 3 designates an aeration device which supplies the excess oxygen for carrying out the nitrification.
Man erkennt, daß das bei 5 zugeführte Abwasser in den belüfteten Kanal 2 mit den Tauchkörpern gelangt, wo die Nitrifikation stattfindet, d.h. eine Nitratbildung erfolgt, worauf das mit Nitrat behaftete Teichwasser dann in die Ruhigwasserzone 6 gelangt, in der am Rande bzw. an der Sohle des Teiches Belebtenschlamm vorhanden ist und Sauerstoffmangel herrscht, so daß dort die Denitrifikation erfolgen kann.It can be seen that the wastewater supplied at 5 enters the ventilated channel 2 with the immersion bodies, where the nitrification takes place, ie nitrate formation takes place, whereupon the pond water contaminated with nitrate then reaches the still water zone 6 , in the edge or at the The bottom of the pond is activated sludge and there is a lack of oxygen so that denitrification can take place there.
Das so gereinigte Wasser fließt bei 7 aus dem Teich ab.The water purified in this way flows out of the pond at 7 .
Um einen besseren Überblick über die Sauerstoffkonzentration im Teich zu haben, können an geeigneter Stelle Meßstellen eingerichtet werden.For a better overview of the oxygen concentration Having them in the pond can have measuring points at a suitable point be set up.
