Abstract

Die Erfindung betrifft komplette Kläranlagen. Eine Einlaufgruppe, Rechenanlage, ein Sandfang, Fettfang, eventuell Stapelbehälter, Pufferbehälter und eine Denitrifikation werden konventionell ausgeführt.
Nitrifikation, Belebungsbecken werden mit einem neu entwickelten Belüftungssystem optimiert, die Nachklärung wurde ebenfalls optimiert.
Durch einseitige Belüftung in der Nitrifikation entsteht eine drehende Wasserwalze mit optimalem Übergang des Sauerstoffs in den Belebtschlamm. Die drehende Wasserwalze funktioniert durch runde Leitbleche ohne Verwirbelung. Der Ablauf in die Nachklärung wird durch einen Leitschacht mit großer Querschnittsfläche verlangsamt. Die Sedimentation beginnt bereits in der Trichterspitze.The invention relates to complete treatment plants. An intake group, computer system, a sand trap, grease trap, possibly stacking containers, buffer tanks and a denitrification are carried out conventionally.
Nitrification, aeration tanks are optimized with a newly developed ventilation system, the secondary clarification has also been optimized.
By one-sided aeration in the nitrification creates a rotating water roller with optimal transition of oxygen into the activated sludge. The rotating water roller works through round baffles without turbulence. The process in the secondary clarification is slowed down by a guide shaft with a large cross-sectional area. The sedimentation begins already in the funnel tip.

Description

Die Erfindung betrifft komplette Kläranlagen. Ein Einlaufgruppe, Rechenanlage, Sandfang, Fettfang, eventuell Stapelbehälter, Pufferbehälter und Denitrifikation werden konventionell ausgeführt.The Invention relates to complete treatment plants. One Inlet group, computer system, sand trap, grease trap, possibly stack container, buffer tank and denitrification are carried out conventionally.

Nitrifikation, Belebungsbecken werden mit einem neu entwickelten Belüftungssystem optimiert, die Nachklärung wurde ebenfalls optimiert.nitrification, Aeration tanks are equipped with a newly developed ventilation system optimized, the final clarification was also optimized.

Um diese Anlagen zu optimieren, habe ich ein Belebungsbecken (Pos. 7) mit einseitigem Belüfterfeld ausgerüstet. Wie aus der Seitenansicht ersichtlich, wird das Rohabwasser mit Belebtschlamm belüftet. Dabei entsteht eine in sich drehende Walze, die im äußeren Bereich viel Luft an der Oberfläche ausgast (8). Je weiter die Belüftung zum inneren Drehpunkt wirksam wird, umso besser ist der Rückhalt der Luft und der Übergang von Sauerstoff zum Belebtschlamm (pos. 8 + 9). Die intensive Durchmischung unterstützt den Übergang des Sauerstoffs.In order to optimize these plants, I have a activated sludge tank (pos. 7 ) equipped with one-sided ventilator field. As can be seen from the side view, the raw sewage is aerated with activated sludge. This results in a rotating roller that outgasses a lot of air at the surface in the outer area ( 8th ). The further the ventilation to the inner fulcrum becomes effective, the better is the retention of the air and the transfer of oxygen to the activated sludge (pos. 8th + 9 ). The intensive mixing supports the transition of oxygen.

Die runden, in 3 Ecken angebrachten Leitbleche 1, 2 und 3 minimieren den reibungsloseren Umlauf. Die Bleche 1 + 2 werden auf Distanz zur Betonwand montiert, damit kein Totraum entsteht. Pos (3) wird direkt an der Betonwand montiert, damit die Ausströmungsgeschwindigkeit gleichmäßig abläuft. Durch einen Schacht wird durch die Dimension eine sehr langsame Fließgeschwindigkeit erreicht. Durch den Ausgang in Richtung Trichterspitze sedimentiert der überwiegende Teil direkt in die Trichterspitze. Die oberhalb des Trichters großflächig ausgebaute Fläche bewirkt durch die weiter verlangsamte Fließgeschwindigkeit eine weitere Sedimentation und damit klares Wasser. Über eine Zahnschwelle wird das gereinigte Wasser gleichmäßig abgezogen. Der sedimentierte Schlamm wird in der Trichterspitze abgezogen und in die Denitrifikation oder in den Stapelbehälter gepumpt.The round baffles mounted in 3 corners 1 . 2 and 3 minimize the smoother circulation. The sheets 1 + 2 are mounted at a distance to the concrete wall so that no dead space is created. Pos ( 3 ) is mounted directly on the concrete wall so that the outflow speed runs smoothly. Through a shaft, a very slow flow rate is achieved by the dimension. Through the exit in the direction of the funnel tip, most of the sediment settles directly into the funnel tip. The large area above the funnel surface causes further sedimentation and thus clear water due to the further slowed flow rate. About a tooth sill, the purified water is removed evenly. The sedimented sludge is withdrawn in the funnel tip and pumped into the denitrification or stacking container.

Dieses Verfahren mit geringem Energieaufwand und automatischer Steuerung erfordert keinen hohen Personalaufwand. Die Module können in beliebiger Anzahl kombiniert werden, bzw. je nach Anfallmenge des Rohabwassers zu- oder abgeschaltet werden. Bei der Abschaltung muss die Nitrifikation und das Nachklärbecken entleert und gesäubert werden.This Low power and automatic control method does not require high personnel costs. The modules can work in any number can be combined, or depending on the amount of seizure of the Raw sewage to be switched on or off. At the shutdown must the nitrification and the secondary clarifier emptied and cleaned become.

Bei Inbetriebnahme erreicht die Anlage innerhalb von ca. 4 Tagen ihre volle Leistung.at Commissioning will reach the plant within approx. 4 days full power.

Für Feriengebäude, Hotels, Campingplätze ist die variable Nutzungsmöglichkeit optimal.For holiday buildings, hotels, Campsites is the variable usage possibility optimal.
