Description
Verfahren zur Einarbeitung von Faulräumen. Die Faulräume der Emscherbrunnen oder anderer zusammengesetzter Absetz- und Schlammfaulanlagen brauchen eine gewisse Zeit der Einarbeitung (Reifung), wenn sie neu in Betrieb genommen werden. Diese Einarbeitung besteht hauptsächlich in der Entwicklung der Fermente der Methangärung. Sie läßt sich dadurch beschleunigen, daß man eine Impfung mit gutem alten Schlamm vornimmt.Procedure for incorporating septic tanks. The lazy rooms of the Emscherbrunnen or other composite sedimentation and sludge digestion systems need a certain amount Time of familiarization (maturation) when they are put into operation. These Training consists mainly in the development of the ferments of methane fermentation. It can be accelerated by vaccinating it with good old mud undertakes.
In einem Emscherbrunnen, bei dem über dem Schlammfaulraum ein vom Abwasser durchflossenes Absitzbecken liegt, läßt sich die Einarbeitung gemäß der Erfindung dadurch beschleunigen, daß man guten Schlamm von der Sohle eines eingearbeiteten Brunnens in den Zulauf zum Emscherbrunnen pumpt. Der gute Schlamm mischt sich dann mit dem Abwasser. Die einzelnen im Abwasser enthaltenen frischen Schlammteile kommen während des Absinkens in innigste Berührung mit Teilen des guten Schlammes, und das Schlammgemisch, das schließlich durch die an der Sohle des Absitzbeckens befindlichen Schlitze in den Faulraum kommt, ist bereits so mit den Fermenten der Methangärung angereichert, daß dieser Schlamm im Faulraum sogleich den Weg der gewollten Methangärung beschreitet, ohne zuerst der sauren Gärung anheimzufallen. Durch rechtzeitiges und häufig wiederholtes Einpumpen von gutem alten Schlamm in den Zulauf von neu in Betrieb genommenen Emscherbrunnen kann die Einarbeitungszeit beliebig verkürzt und sogar vollständig vermieden werden. 0 Schlammteile, die in der Schwimmdecke des Faulraums eines Emscherbrunnens -festsitzen, werden von dem in der beschriebenen Weise zugeführten Impfschlamm nicht berührt. Um die Wirkung des zugeführten Schlammes auch auf die Schwimmdecke auszudehnen, kann es bei ausnahmsweise starker Schwimmdeckenbildung nötig sein, das beschriebene Verfahren dadurch zu ergänzen, daß ein Teil des alten Schlammes auf den Schwimmschlamm des Faulraums gepumpt wird, damit auch dieser mit altem Schlamm gemischt und zum Absinken gebracht wird.In an Emscher well, in which a sedimentation basin through which sewage flows is located above the sludge digester, the incorporation according to the invention can be accelerated by pumping good sludge from the bottom of an incorporated well into the inlet to the Emscher well. The good sludge then mixes with the wastewater. The individual fresh sludge parts contained in the waste water come into intimate contact with parts of the good sludge during the sinking process, and the sludge mixture that finally comes through the slits on the bottom of the sedimentation basin into the septic tank is already enriched with the ferments of methane fermentation, that this sludge in the digester immediately follows the path of the desired methane fermentation without first succumbing to acid fermentation. By pumping good old sludge into the inflow of newly commissioned Emscher wells in good time and often repeated, the familiarization period can be shortened as required and even avoided completely. 0 Sludge parts that are stuck in the floating cover of the septic tank of an Emscher well are not affected by the inoculation sludge supplied in the manner described. In order to extend the effect of the supplied sludge to the floating cover, it may be necessary, in the case of exceptionally strong floating cover formation, to supplement the described method by pumping part of the old sludge onto the floating sludge of the septic chamber so that it is also mixed with old sludge and is brought to sink.
Wenn in einem bereits eingearbeiteten Faulraum infolge von Betriebsfehlern oder von äußeren Einflüssen, z. B. Kälte, nachträglich saure Gärung auftritt, beginnt diese im oberen Teil des Faulraums. Sie kann dann rasch durch die beschriebenen Mittel des Einpumpens von altem Schlamm in den Zulauf und falls erforderlich, auch auf die Schwimmdecke bekämpft und beseitigt werden. Meist genügt es dabei, den guten Schlamm von der Sohle des gleichen Brunnens zu nehmen. Nur wenn sich die saure Gärung auf den gesamten Faulrauminhalt erstreckt, wird es erforderlich, den guten Schlamm von einem andern Brunnen zuzuführen.If in a digester that has already been incorporated as a result of operational errors or from external influences, e.g. B. Cold, subsequent acidic fermentation occurs begins these in the upper part of the digester. You can then quickly go through the described Means of pumping old sludge into the inlet and, if necessary, also on the floating cover are combated and eliminated. Usually it is enough to use the good ones To take mud from the bottom of the same well. Only when there is acid fermentation extends to the entire septic tank contents, it becomes necessary to use the good sludge to be supplied from another well.
