Description
Anlage zur biologischen Reiniguhg'Vbh AbVuas'sGr **: Plant for biological purification AbVuas'sGr **:
Die Erfindung betrifft eine Anlage zur biologischen Reinigung kommunaler und organisch hochbelasteter industrieller Abwässer in Form einer Durchlaufanlage.The invention relates to a plant for the biological purification of municipal and organically highly contaminated industrial wastewater in the form of a flow-through plant.
Es gibt eine Vielzahl von konventionellen Kläranlagen zur Reinigung vorgenannter Abwässer, die nach biologischen Verfahren arbeiten. In der Regel handelt es sich hierbei um Anlagen die in Vorklärung, Belebung und Nachklärung aufgeteilt sind. Diese Anlagen weisen somit einen großen Flächen- und Raumbedarf auf. Kompaktkläranlagen, die im Durchlaufprinzip arbeiten, erfordern für die Aufgaben der weitergehenden Abwässerreinigung erhebliche und verfahrenstechnisch schwierige Pumpeinrichtungen um die Prozeß- und Schlammrückführungen zu realisieren.There are a number of conventional sewage treatment plants for cleaning the aforementioned wastewater, which work according to biological processes. These are usually plants that are divided into primary treatment, aeration and secondary treatment. These plants therefore have a large area and space requirement. Compact sewage treatment plants that work on the flow-through principle require considerable and technically complex pumping equipment for the tasks of further wastewater treatment in order to implement the process and sludge returns.
Die Aufgabe der Erfindung besteht darin, eine Anlage zur biologischen Reinigung von Abwasser zu schaffen, die den Anforderungen der weitergehenden Abwasserreinigung, sprich Stickstoff und biologische P-Elimination, realisiert und in kompakter Bauweise errichtet werden kann.The object of the invention is to create a plant for the biological purification of wastewater that meets the requirements of advanced wastewater purification, i.e. nitrogen and biological P elimination, and can be constructed in a compact design.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß eine nach dem Belebtschlammverfahren arbeitende Kläranlage durch einen senkrecht durchströmten Nachklärtrichter bzw. mehrere Nachklärtrichter ergänzt wird. Erfindungsgemäß wird weiterhin das Problem der Prozeßwasserrezirkulation und der Rücklaufschlammführung dadurch gelöst, daß ein handelsübliches Bodenrührwerk in getauchter bzw. über Wellenantrieb unterhalb des Nachklärtrichters so installiert wird, daß ständig eine ausreichende Menge Prozeßwasser und Rücklaufschlamm, welcher sich im Nachklärtrichter separiert, in die Belebtschlamm-zone zurückgeführt wird und in der Belebtschlammzone bei Belüftungspausen mit dem gleichen Gerät in Schwebe gehalten wird. Somit vereinigt die vorbeschriebene Anlage die Belebung, Denitrifikation, Nitrifikation, biologisch P und Nachklärung je nach Auslegung in einem Behälter. Durch die kompakte Anordnung von Behältern in Stahl oder Beton, Nachklärtrichter in GFK, Beton oder Stahlblech und in der Erfindungsgemäß beschriebenen Anordnung mit Belebungsraum, Nachklärtrichter und Betonrührwerk mit integrierter Begasung oder getrennter Belüftung über ein separates Belüftungssystem werden niedrige Bau- und Montagekosten und niedriger Flächen- und Raumbedarf sowie niedrige Energiekosten für den Betrieb der Anlage bei dem Reinigungsziel der Stickstoff und biologischen Phosphorelimination erreicht. Die Erfindung ist an der Zeichnung beispielsweise dargestellt.According to the invention, the problem is solved by supplementing a sewage treatment plant operating according to the activated sludge process with a vertically flowing secondary clarification funnel or several secondary clarification funnels. According to the invention, the problem of process water recirculation and return sludge management is also solved by installing a commercially available bottom agitator in a submerged or shaft drive below the secondary clarification funnel in such a way that a sufficient amount of process water and return sludge, which separates in the secondary clarification funnel, is constantly returned to the activated sludge zone and is kept suspended in the activated sludge zone during aeration breaks using the same device. The system described above thus combines aeration, denitrification, nitrification, biological P and secondary clarification in one container, depending on the design. The compact arrangement of containers in steel or concrete, secondary clarification funnels in GRP, concrete or sheet steel and the arrangement described in the invention with aeration chamber, secondary clarification funnel and concrete agitator with integrated gassing or separate ventilation via a separate ventilation system results in low construction and assembly costs and low area and space requirements as well as low energy costs for operating the system with the cleaning objective of nitrogen and biological phosphorus elimination. The invention is shown as an example in the drawing.
Die Abwasserbehandlungsanlage besteht aus dem offenen Behälter (3), dem Pumpenschacht (2) -der Pumpenschacht kann entfallen, sofern ein freier Zulauf möglich ist-. Über die Zulaufleitung 7 fließt das mechanisch vorgereinigte Abwasser in den Belebungsbereich derThe wastewater treatment plant consists of the open tank (3), the pump shaft (2) - the pump shaft can be omitted if a free inflow is possible. The mechanically pre-treated wastewater flows via the inlet line 7 into the aeration area of the

Kompaktkläranlage. Über eine oder meh'rere EiniatiTveenchtung' (8J gelangt das Abwasser in den inneren Bereich des Nachklärtrichters (1). Hier trennt sich sedimentativ Belebtschlamm und Klarwasser, dabei bildet sich ein durchgehender Flockenfilter. Dieser Flockenfilter verfeinert und vervollständigt die Trennung zwischen Klarwasser und Belebt-schlamm. Der Belebtschlamm wird über das Bodenrührwerk (2) in den Belebungsbereich (9) gefördert. Je nach Ausführung der Belüftung (5) wird das Abwasser über ein feinblasiges Belüftungssystem oder über eine grobblasige Vorbelüftung, welche durch das Boden-rührwerk (2) eine feine Blase erzeugt, mit Sauerstoff versorgt.Compact sewage treatment plant. The wastewater reaches the inner area of the secondary clarification funnel (1) via one or more inlet conduits (8). Here, activated sludge and clear water are separated by sedimentation, forming a continuous floc filter. This floc filter refines and completes the separation between clear water and activated sludge. The activated sludge is conveyed to the aeration area (9) via the bottom agitator (2). Depending on the design of the aeration (5), the wastewater is supplied with oxygen via a fine-bubble aeration system or via a coarse-bubble pre-aeration, which creates a fine bubble via the bottom agitator (2).
Je nach Reinigungsziel und Sauerstoffversorgung kann die Belüftung (5) über diverse Regelstrategien (Redox, 02, Ammonium, Nitrat) gesteuert werden und somit der Reinigungsprozeß einer Regelung unterzogen werden. Über die Ablaufrinne/n (10) gelangt das Wasser in die Ablaufsammelleitung und über die Leitung (12) in den Ablauf (4) der Kläranlage.Depending on the cleaning objective and oxygen supply, the aeration (5) can be controlled using various control strategies (redox, 02, ammonium, nitrate) and thus the cleaning process can be regulated. The water flows via the drain channel(s) (10) into the drain collection line and via the line (12) into the drain (4) of the sewage treatment plant.
