Die Nutzbarmachung der Sulfitzelluloseablauge tür technische und landwirtschaftliche
Zwecke, z. B. als Dünge- und Futtermittel, ist schon vielfach vergeblich versucht worden.
Es sind wesentlich zwei Eigenschaften der Ablauge, welche ihrer allgemeinen Verwendung
im Wege stehen.The utilization of sulphite cellulose waste liquor for technical and agricultural purposes, e.g. B. as fertilizer and animal feed, has been tried many times in vain.
There are essentially two properties of the waste liquor which stand in the way of its general use.
Einmal wirkt störend der Gehalt an schwefliger Säure beziehentlich solcher Verbindungen, welche leicht schweflige Säure abspalten, und der Kalk.On the one hand, the content of sulphurous acid or such compounds has a disruptive effect which easily split off sulphurous acid, and lime.
Weiter kommt in Betracht das fast gänzliche Fehlen eiweißartiger Stoffe in der Ablauge, die ihr erst einen Wert als Futtermittel geben bzw. ihren Düngewert erhöhen.Another consideration is the almost complete absence of protein-like substances in the waste liquor, which first give it a value as animal feed or increase its fertilizer value.
Gegenstand vorliegender Erfindung ist eine Behandlung der Ablauge, welche die genannten Mängel beseitigt.The subject of the present invention is a treatment of the waste liquor, which the above Defects eliminated.
Es hat sich gezeigt, daß die Sulfitablauge einen recht guten Nährboden" abgibt für oxydierend wirkende Mikroben, durch deren Tätigkeit die erwähnten Schwefelverbindungen zu unschädlicheren Verbindungen oxydiert werden. Beispielsweise sind folgende Bakterien für diesen Zweck geeignet: Bac. subtil., Bac. vulgatus, Bac. acet., Bac. mycoid., Bac. Pasteur, Bac. acid. lact.It has been shown that the sulphite waste liquor is a very good breeding ground for oxidizing Effective microbes, through whose activity the sulfur compounds mentioned are oxidized to less harmful compounds. For example, the following bacteria are suitable for this purpose: Bac. subtle., Bac. vulgatus, Bac. acet., Bac. mycoid., Bac. Pasteur, Bac. acid. lact.
Abgesehen von der Oxydation, welche durch die Mikroben bewirkt wird, wobei ein wesentlicher Teil des Kalkes an die gebildete Schwefeisäure unter Bildung von Calciumsulfat gebunden wird, erfährt die Ablauge auch durch die Mikrobenleiber eine Anreicherung an nützlichen, organischen Verbindungen.Apart from the oxidation, which is caused by the microbes, being an essential one Part of the lime bound to the sulfuric acid formed with the formation of calcium sulfate becomes, the waste liquor experiences an enrichment of useful, organic compounds.
Das Verfahren kann z. B. so ausgeführt werden, daß die gewählte Mikrobenart, oder auch einige derselben, auf Ablauge enthaltenden Nährböden in Reinkultur gezüchtet, und daß dann die Hauptmasse der Lauge mit dieser Reinkultur geimpft wird.The method can e.g. B. be carried out so that the selected type of microbe, or also some of the same culture media containing waste liquor are grown in pure culture, and that then the main mass of the lye is inoculated with this pure culture.
Die Umwandlung der Lauge wird durch Zuführung von Luft unterstützt, z. B. in der Weise, daß man die geimpfte Lauge über Gradierwerke o. dgl. rieseln läßt.The conversion of the liquor is supported by the addition of air, e.g. B. in the Way that you let the inoculated lye trickle over graduation works or the like.
Gegebenenfalls wird die Lauge oder auch der Raum, in dem das Gradierwerk steht, angemessen erwärmt; es kann auch nützlich sein, die Lauge mehrmals über das Gradierwerk laufen zu lassen.If necessary, the lye or the room in which the graduation tower is located is appropriate warmed; it can also be useful to run the lye several times over the graduation tower.
Um die Arbeit der Mikroben zu erleichtern,To make the work of the microbes easier,
<s\<s \
kann der Rohlauge, wie sie den Kochern entnommen wird, also vor der Impfung, nach bekannten chemischen Methoden möglichst viel der unerwünschten Schwefelverbindungen entzogen werden.can after the raw liquor as it is taken from the cooker, i.e. before inoculation known chemical methods as much as possible of the undesired sulfur compounds be withdrawn.
Es empfiehlt sich, den für das gedeihliche Wachsen der Mikroben wünschenswerten neutralen beziehungsweise alkalischen Zustand vor der Impfung zu schaffen, auch können solche Zusätze Verwendung finden, welche geeignet sind, das Wachstum der Mikroben zu fördern. Um der Lauge Eiweißverbindungen einzuverleiben, wird die von lästigen Schwefelverbindungen möglichst befreite Ablauge nach beliebiger Methode mittels Sproßpilzen, z. B. , Hefe, vergoren und dann mit den entstandenen Pilzen so weit entwässert, wie es für die Verwendung z. B. als Futter- oder Düngemittel zweckmäßig erscheint.It is advisable to use the neutral one that is desirable for the microbes to thrive Such additives can also be used to create or alkaline state before vaccination Find use which are suitable to promote the growth of the microbes. To incorporate protein compounds into the lye, the waste liquor freed from annoying sulfur compounds as possible by any method using fungi, z. B. , Yeast, fermented and then dehydrated with the resulting mushrooms as much as it is for the use z. B. appears appropriate as feed or fertilizer.
Auch hier können der Ablauge noch andere vergärbare Produkte beigemischt werden, um eine möglichst hohe Ausbeute an Hefe und damit einen erhöhten Nähr- oder Düngewert der Ablauge zu erzielen.Here, too, other fermentable products can be added to the waste liquor the highest possible yeast yield and thus an increased nutritional or fertilizer value to achieve the waste liquor.
Es können z. B. die bei der Zellulosefabrikation entstehenden Holzabfälle durch geeignete Behandlung vergärbar gemacht und der Rohlauge vor der Vergärung zugefügt werden. Auch vergärbare Abfallstoffe der Zucker-Industrie, Stärkeindustrie usw. können verwendet werden.It can e.g. B. the resulting wood waste in cellulose production through suitable Treatment made fermentable and added to the raw liquor before fermentation. Fermentable waste materials from the sugar industry, starch industry, etc. can also be used will.
Die vor der Vergärung nötige Neutralisierung der Lauge wird vorteilhaft wenigstens teilweise bewirkt durch die Asche, welche die in den Zellulosefabriken vielfach eingeführten Holzabfallfeuerungen liefern.The neutralization of the liquor, which is necessary before fermentation, is at least advantageous partly caused by the ashes which are often imported into the cellulose factories Supply wood waste firing.
Da entsprechend dem Zwecke des vorliegenden Verfahrens eine möglichst hohe Hefeausbeute angestrebt wird, und die Stoffwechselprodukte der Sproßpilze, z. B. Alkohol und Kohlensäure, im vorliegenden Fall nur wertlose Nebenprodukte darstellen, so erfolgt eine Vergärung zweckmäßig in der schon oben erwähnten Weise durch Überleiten der geimpften Ablauge über Gradierwerke.Since, according to the purpose of the present process, the highest possible yeast yield is sought, and the metabolic products of the fungi, z. B. alcohol and carbon dioxide, in the present case only worthless If byproducts represent, fermentation expediently takes place in the manner already mentioned above Way by passing the inoculated waste liquor over graduation towers.
Die zur Impfung verwendeten Sproßpilze werden praktisch als Reinkulturen gezüchtet in oder auf Nährböden, welchen von Generation zu Generation immer mehr Ablauge zugesetzt wird. .The mushrooms used for vaccination are practically grown as pure cultures in or on nutrient media to which more and more waste liquor has been added from generation to generation will. .
Die nach dem Verfahren behandelte Ablauge kann in beliebiger Weise entwässert in Stück- oder Pulverform gebracht werden.The waste liquor treated by the process can be dewatered in any way Brought in bar or powder form.
