Mehrstufige Kleinkläranlage für häusliche AbwässerMulti-stage small sewage treatment plant for domestic wastewater

Die Erfindung betriflt eine mehrstufige Kleinkläranlage tür häusliche Abwässer, bestehend aus mechanischer Grobentschlammung und nachgeschalteten Klärbehältern. Bekannte Kleinkläranlagen neigen bei stark schwankenden Zuflüssen und bei plötzlichen Betriebsunterbrechungen zu kritischen Betriebszuständen. Tritt nach einer Betriebsunterbrechung oder nach einer Phase sehr geringer Belastung stossartig eine sehr hohe Belastung auf, kann auch eine relativ betriebssicher arbeitende Kleinkläranlage gemäss DE 195 34 657 Al sehr schnell in kritische Betriebszustände kommen. Eine eventuelle, ursprünglich nicht geplante Erhöhung der Belastung durch Anschluss zusätzlicher Einwohner kann die genannte Kleinkläranlage ebenfalls sehr schnell überfordern.The invention relates to a multi-stage small sewage treatment plant for domestic wastewater, consisting of mechanical coarse sludge removal and downstream treatment tanks. Known small sewage treatment plants tend to reach critical operating conditions when there are strong fluctuations in inflows and when there are sudden interruptions in operation. If a very high load suddenly occurs after an interruption in operation or after a phase of very low load, even a relatively reliable small sewage treatment plant according to DE 195 34 657 Al can very quickly reach critical operating conditions. A possible, originally unplanned increase in load due to the connection of additional residents can also very quickly overwhelm the small sewage treatment plant mentioned.

Der Erfindung liegt daher die Aufgabe zugrunde, eine auch bei extrem wechselnden Belastungszuständen und unvorhergesehenem Belastungszuwachs hochwirksame und äusserst betriebssicher arbeitende Kleinkläranlage zu schaffen. Diese Aufgabe wird nach der Erfindung gelöst durch eine mehrstufige Kleinkläranlage, bestehend aus der mechanischen Grobentschlammung und mindestens zwei nachgeschalteten, gleichartig aufgebauten Klärbehältern.The invention is therefore based on the object of creating a small sewage treatment plant that is highly effective and extremely reliable even under extremely changing load conditions and unforeseen load increases. This object is achieved according to the invention by a multi-stage small sewage treatment plant, consisting of the mechanical coarse sludge removal and at least two downstream, similarly constructed sewage tanks.

Die mechanische Grobentschlammung hält groben Schlamm und sperrige Gegenstände zurück. Die der mechanischen Grobentschlammung nachgeschalteten Klärbehälter sind in sich völlig gleichartig aufgebaut und arbeiten nach dem bekannten Aufstaubelebungsverfahren. Jeder Klärbehälter stellt eine Kombination aus Vorspeicherbehälter und Bioreaktor dar und ist also zugleich Vorspeicher für den nachfolgenden Klärbehälter. Steuerung, Belüftung, Umwälzung, Einlass, Überleitung und Auslass des Wassers erfolgen durch bekannte Vorrichtungen. Durch die Kombination von Bioreaktor und Vorspeicher in einem Behälter und die Zusammenschaltung der einzelnen Reinigungsstufen in Form einer mehrstufige Kleinkläranlage wird ein sehr sicherer Betrieb und eine sehr hohe Reinigungsleistung auch bei extremen Belstungen und Belastungsschwankungen der Kleinkläranlage sichergestellt. Die hohen Leistungsreserven dieser mehrstufigen Kleinkläranlage ermöglichen es, das Gesamtarbeitsvolumen der Anlage zu verkleinern oder aber im umgekehrten Fall wesentlich mehr Einwohner an ein bestimmtes Arbeitsvolumen anzuschliessen.The mechanical coarse sludge removal holds back coarse sludge and bulky objects. The sewage treatment tanks downstream of the mechanical coarse sludge removal are constructed in a completely identical manner and work according to the well-known aeration process. Each sewage treatment tank is a combination of a pre-storage tank and a bioreactor and is therefore also a pre-storage tank for the subsequent sewage treatment tank. Control, ventilation, circulation, inlet, transfer and outlet of the water are carried out by well-known devices. The combination of bioreactor and pre-storage tank in one tank and the interconnection of the individual cleaning stages in the form of a multi-stage small sewage treatment plant ensures very safe operation and a very high cleaning performance even under extreme loads and load fluctuations in the small sewage treatment plant. The high performance reserves of this multi-stage small sewage treatment plant make it possible to reduce the total working volume of the plant or, conversely, to connect significantly more residents to a certain working volume.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt:An embodiment of the invention is shown in the drawing. It shows:

Fig. 1 einen Schnitt durch eine zweistufige Kleinkläranlage . 35Fig. 1 a section through a two-stage small sewage treatment plant . 35

Bei der in der Zeichnung gezeigten zweistufigen Kleinkläranlage fliesst das Abwasser durch die Zulaufleitung 1 in die Grobentschlammung 2. Durch die tauchrohrgesicherte Überlaufleitung 3 fliesst das vorgereinigte Abwasser in den Klärbehälter 4 der ersten Reinigungsstufe.
Der Klärbehälter 4 arbeitet nach dem Aufstaubelebungsverfahren und stellt eine Kombination von Bioreaktor und Vorspeicherbehälter dar, ist also Vorspeicher für den Klärbehälter 8 der zweiten Reinigungsstufe.In the two-stage small sewage treatment plant shown in the drawing, the wastewater flows through the inlet line 1 into the coarse sludge removal system 2. The pre-treated wastewater flows through the dip-pipe-protected overflow line 3 into the treatment tank 4 of the first treatment stage.
The clarification tank 4 operates according to the aeration process and represents a combination of bioreactor and pre-storage tank, i.e. it is a pre-storage tank for the clarification tank 8 of the second purification stage.

Im Klärbehälter 4 wird das Abwasser zulaufbedingt aufgestaut und durch die Belüftervorrichtung 5 umgewälzt und belüftet. Hat der Wasserspiegel das obere Niveau 2 erreicht, leitet eine Steuerautomatik den Absetzvorgang und die Überleitung des gereinigten Wassers durch die Pumpe 6 und die Überlaufleitung 7 in den Klärbehälter der zweiten Reinigungs-stufe ein. Hat die Pumpe 6 im Klärbehälter 4 den Wasserspiegel wieder bis zum unteren Niveau 1 abgesenkt, unterbricht die Steuerautomatik den Abpumpvorgang. Die Arbeitsvorgänge beginnen von vorn. Im Klärbehälter 8 , welcher in sich völlig dem Klärbehälter 4 entspricht und welcher ebenfalls nach dem Aufstaubelebungsverfahren arbeitet, verlaufen alle Arbeitsvorgänge identisch zu denen im Klärbehälter 4. Das endgereinigte Wasser wird durch die Pumpe 6 des Klärbehälters 8 mittels der Ablaufleitung 9 nach aussen abgeleitet.In the clarification tank 4, the wastewater is dammed up due to the inflow and circulated and aerated by the aeration device 5. When the water level has reached the upper level 2 , an automatic control system initiates the settling process and the transfer of the purified water through the pump 6 and the overflow line 7 into the clarification tank of the second cleaning stage. When the pump 6 in the clarification tank 4 has lowered the water level back to the lower level 1 , the automatic control system interrupts the pumping process. The work processes start again from the beginning. In the clarification tank 8, which is completely identical to the clarification tank 4 and which also works according to the damming aeration process, all work processes are identical to those in the clarification tank 4. The finally purified water is drained outside by the pump 6 of the clarification tank 8 via the drain line 9.
