Description
Verfahren zur biologischen Reinigung der Zuckerfabrikabwässer unter Benutzung der Fabrikabwärme. Bei der biologischen Reinigung von Zuckerfabrikabwässern durch Vergärung in Teichen oder Bassins hat sich die Schwierigkeit gezeigt, eine vollständige regelmäßige Ve-gärung herbeizuführen. Es ist nämlich. zu kostspielig, die Temperaturen des Abwassers zu regeln, aus welchem Grunde die Gärungsorganismen erlahmten oder abstarben, sobald infolge WitterLin-sänderung; pbesonders starker Kälte oder starker heftiger Winde die Temperatur des Wassers in die Nähe des Gefrierpunktes fiel.Process for the biological purification of the sugar factory wastewater under Use of waste heat from the factory. In the biological treatment of waste water from sugar factories fermentation in ponds or basins has shown the difficulty of producing a to bring about complete regular fermentation. Because it is. too expensive To regulate the temperature of the wastewater, for which reason the fermentation organisms paralyzed or died as soon as a change in the WitterLin; p particularly stronger Cold or strong violent winds bring the temperature of the water to near freezing point fell.
Das vorliegende Verfahren besteht darin, daß man nicht die ganze Menge der Zuckerfabrikabwässer durch Abwärme auf die geeignete Vergärungstemperatur bringt, sondern daß man nur den Teil der Abwässer, welcher der zur Verfügung stehenden Abwärme entspricht, auf die für die Entwicklung der Gärungsorganismen günstige Temperatur bringt und nunmehr vergären läßt, worauf dann dieses vergorene Abwasser mit seinen Organismen in das übrige kalte Abwasser geleitet und die ganze Abwassermenge weiter vergoren wird.The present method is that you don't get the whole lot the sugar factory wastewater uses waste heat to bring it to the appropriate fermentation temperature, but that only that part of the waste water, which of the available waste heat corresponds to the temperature favorable for the development of the fermentation organisms brings and now lets ferment, whereupon this fermented wastewater with his Organisms passed into the rest of the cold wastewater and the entire amount of wastewater passed on is fermented.
Die Temperatur des iu der Wärme zu vergärenden Abwassers ist für die Milchsäuregäreng auf etwa q.o bis 45' C oder für die Hefegärung auf 3o bis q.0° C zu halten.The temperature of the waste water to be fermented iu the heat is for the Lactic acid fermentation to about q.o to 45 ° C or for yeast fermentation to 3o to q.0 ° Hold C.
Das Verfahren beruht auf der neuen Beobachtung, daß das bei konstanter Temperatur von q.o bis q.5° C für Milchsäuregärung, 30 bis 40 ' C für Hefegärung vergorene Wasser größere Mengen kaltes Abwasser in eine weit stärkere Vergärung versetzt, als eintritt, wenn das kalte Wasser für sich allein der Teich gäreng unterliegt. Die Ausführung des Verfahrens kann beispielsweise in folgender Weise geschehen.The method is based on the new observation that the constant Temperature from q.o to q.5 ° C for lactic acid fermentation, 30 to 40 ° C for yeast fermentation fermented water larger amounts of cold wastewater in a far stronger fermentation offset than occurs when the cold water alone undergoes fermentation in the pond. The method can be carried out, for example, in the following manner.
Es sind eine Reihe von Gärkästen bzw. Gärbassins und von Absatzkästen, Bassins oder Teichen vorgesehen. Je nach der zur Verfügung stehenden Abwärme beschickt man nun die mit Heizschlangen, Schnattern u. dgl. versehenen Gärkästen oder Bassins mit dem Abwasser und leitet die Abwärme hinzu. Steht eine große Menge von Abwärme zur Verfügung, so erwärmt man mehr Gärkästen und lcitet in dieselben auch größere Mengen von Abwässer, um gleichmäßige Temperatur zu erzielen. Wenn sehr viel Abwärme zur Verfügung steht, kann man auch die Absatzkästen beheizen und auch die nachfolgenden Klärteiche, indem man die warmen Abgase o. dgl. direkt ins Wasser bläst.There are a number of fermentation boxes or fermentation basins and heel boxes, Basins or ponds provided. Charged according to the available waste heat the fermentation boxes or basins equipped with heating coils, chatter and the like with the wastewater and transfers the waste heat to it. There is a large amount of waste heat available, more fermentation boxes are heated and larger ones are also used Amounts of sewage to achieve uniform temperature. If a lot of waste heat is available, you can also heat the sales boxes and the following ones Clarifying ponds by blowing the warm exhaust gases or the like directly into the water.
