Abstract
Description
Es werden ein Verfahren zur Reinigung von Abwasser und eine Kläranlage, insbesondere Kleinkläranlage oder kleine Kläranlage, zur Durchführung dieses Verfahrens beschrieben. Bei dem Verfahren wird das Abwasser nach Durchlaufen der mechanischen Vorreinigung einer Kammer zugeführt, in dem das eigentliche biologische Reinigungsverfahren stattfindet. Die Reinigung erfolgt dergestalt, dass während einer Füllphase dieser Kammer das Abwasser mittels Belüftungseinrichtungen mit Sauerstoff versorgt und dabei gleichzeitig umgewälzt wird. Nach Abschluss der Füll- und Belüftungsphase mit entsprechenden Pausenzeiten wird die Belüftungseinrichtung und damit die Umwälzung des Wassers beendet. In der darauffolgenden Absetzphase setzt sich der belebte Schlamm ab. Das gereinigt Abwasser in der sog. Klarwasserphase wird von einer Mammutpumpe abgezogen und einem kombinierten Probeentnahme- und Überlaufgefäss zugeführt, welches mit dem Ablauf der Kläranlage verbunden ist. Dadurch wird gewährleistet, dass auch bei diskontinuierlichem Betrieb jederzeit sowohl für die Wasserbehörde als auch für den Wartungsdienst eine Probenahmemöglichkeit besteht. Anschließend wird über ein fest installiertes Abzugssystem der Überschußschlamm automatisch abgezogen.There is a process for wastewater treatment and a wastewater treatment plant, especially a small wastewater treatment plant Wastewater treatment plant to carry out this process described. In the process, the wastewater is after Going through the mechanical pre-cleaning of a chamber fed in which the actual biological Cleaning process takes place. The cleaning is done such that during a filling phase of this chamber the Waste water by means of aeration devices with oxygen is supplied and circulated at the same time. To Completion of the filling and ventilation phase with the appropriate The ventilation device and thus the pause times Circulation of the water ended. In the following The activated sludge settles out. The wastewater in the so-called clear water phase is cleaned by deducted from a mammoth pump and a combined one Sampling and overflow vessel supplied, which with the sewage treatment plant is connected. This will ensures that even with discontinuous operation at any time both for the water authority and for the Maintenance service has a sampling option. Then a permanently installed fume cupboard system the excess sludge is automatically drawn off.
Nach Abschluss der Überschussschlammabzugsphase beginnt erneut die Füll- und Belüftungsphase. Wesentlich ist, dass das Abwasser in einem kombinierten Belebungs/Nachklärbecken gereinigt wird bei gleichzeitigem diskontinuierlichem Betrieb und ausschliesslich unter Einsatz von luftbetriebenen Belüftungs-, Umwälz- und Abpumpvorgängen einschl. der Rückführung von Überschussschlamm in die Vorklärung.After completion of the excess sludge withdrawal phase the filling and ventilation phase begins again. It is essential that the wastewater combined in one Aeration / clarifier is cleaned at the same time discontinuous operation and exclusively under use of air-powered ventilation, circulation and Pumping operations including the return of Excess sludge in the primary clarification.
Die Kläranlage arbeitet nach dem Belebtschlammprinzip im Aufstauverfahren (Einbecken- oder SBR-Anlage). Es werden dabei die Schmutzstoffe aus dem Abwasser von schwebenden Mikroorganismen (Belebtschlamm) aufgenommen und in Biomasse umgewandelt.The wastewater treatment plant works on the activated sludge principle in Damming process (single pool or SBR system). It the contaminants from the wastewater from floating microorganisms (activated sludge) recorded and converted into biomass.
Durch den ständigen Sauerstoffüberschuss während der Belüftungsphase werden die Mikroorganismen (Biomasse) aktiv gehalten und der entstehende Belebtschlamm, der bis zur Schlammabfuhr in der Belebung verbleibt, aerob stabilisiert.Due to the constant excess of oxygen during the Ventilation phase, the microorganisms (biomass) kept active and the resulting activated sludge that up to remains in the aeration for sludge removal, aerobic stabilized.
Das bedeutet, dass alle abbaubaren Stoffe im Schlamm, die normalerweise zur Faulung führen, biologisch abgebaut werden. Eine Geruchsbelästigung ist somit ausgeschlossen. Die Anlage ist so bemessen, dass der Belebtschlamm, der in einem halben Jahr ensteht, mindestens dort bis zur Abfuhr verbleiben kann.That means all the degradable substances in the sludge that normally lead to digestion, biodegraded become. An odor nuisance is therefore excluded. The plant is dimensioned so that the activated sludge, which is in half a year, at least there until the removal can remain.
Der Belüfter und die Mammutpumpen sind an einem Zentralrohr befestigt. Mit einem fest installierten Schwimmer wird ermittelt, ob ein Klarwasserabzug in den Nachtstunden erforderlich ist. Die komplette Maschinentechnik kann zu Wartungszwecken mittels zentralem Montagerohr durch den Deckel der Kläranlage herausgezogen werden.The aerator and the mammoth pumps are in one Central tube attached. With a fixed float it is determined whether there is a clear water drain at night is required. The complete machine technology can Maintenance purposes by means of a central mounting tube through the The cover of the sewage treatment plant.
Die Kläranlage besteht aus einem Behälter. Das Abwasser gelangt zuerst in eine integrierte Zweikammervorklärung. Von dort wird das Abwasser während der Füllphase mittels einer Mammutpumpe in regelmäßigen Abständen in die Belebung gefördert. Dies ist notwendig, um den Wasserstand der Vorklärung ständig niedrig zu halten, um während der Absetz- und Abzugsphase einen Puffer für das während dieser Zeit der Anlage zufließende Abwasser zu haben.The sewage treatment plant consists of a container. The sewage first goes to an integrated two-chamber clarifier. Of there the wastewater during the filling phase by means of a Mammoth pump in the revival at regular intervals promoted. This is necessary to check the water level Keep clarification constantly low so that during the and withdrawal phase a buffer for that during this period of Plant to have inflowing wastewater.
Die Belüftung erfolgt intermittierend über den Belüfter. Die Belüftungszeit wird so eingestellt, dass ein Mindestsauer stoffgehalt von 1 mg/l nicht unterschritten wird.The ventilation takes place intermittently via the aerator. The ventilation time is set so that a minimum acid substance content of 1 mg / l is not undercut.
In den Nachtstunden, etwa ab 1 Uhr, wird der Belüfter abgestellt und es beginnt die Absetzphase. Die in dieser Zeit anfallenden geringen Abwassermengen werden im Puffer der Vorklärung gespeichert. Nach 2 Stunden Absetzzeit wird über eine Klarwasserpumpe das gereinigte Abwasser abgeleitet. über einen Schwimmer wird der Ausschaltpunkt der Pumpe festgelegt. Falls infolge eines Defektes dieser Minimalwasserstand nicht erreicht werden kann, wird über diesen Schwimmer Alarm ausgelöst. Anschließend wird über ein fest installiertes Abzugssystem der Überschussschlamm automatisch zur Vorklärung abgezogen.During the night, around 1 a.m., the aerator is activated switched off and the weaning phase begins. The at that time accumulating small amounts of waste water are in the buffer Preliminary clarification saved. After 2 hours of settling time, over a clear water pump drains the cleaned wastewater. The switch-off point of the pump is determined by a float fixed. If due to a defect this The minimum water level cannot be reached triggered this float alarm. Then over a permanently installed extraction system for the excess sludge automatically deducted for clarification.
Ist um ca. 19 Uhr der Schwimmer noch nicht eingeschaltet, kann davon ausgegangen werden, dass die Auslastung der Anläge sich stark verringert hat. Die Anlage schaltet in einen Sparbetrieb. Während dieser Phase werden die Belüftungszeiten reduziert. Schaltet der Schwimmer ein, arbeitet die Anlage im Normalbetrieb weiter.If the float is not switched on at around 7 p.m. can be assumed that the utilization of the Investments has decreased significantly. The system switches into one Economy. During this phase, the Ventilation times reduced. If the float switches on, the system continues to operate in normal operation.
Nach beendetem Überschussschlammabzug wird die intermittierende Belüftung wieder eingeschaltet. Die Anlage ist also auf eine Zykluszeit von 24 Stunden eingestellt.After the excess sludge has been removed, the intermittent ventilation switched on again. The facility is set to a cycle time of 24 hours.
Da der Belebtschlamm sich in der Belebung anreichert, ist dieser Überschussschlamm entweder über die SPS automatisch oder durch den Wartungsdienst abzuziehen. Der Schlamm in der Vorklärung ist halbjährlich oder jährlich entsprechend der Bemessung abzufahren. Since the activated sludge accumulates in the activation, is this excess sludge either through the PLC to be deducted automatically or by the maintenance service. The sludge in the primary clarifier is semi-annually or annually to depart according to the dimensioning.
