'Die bisherigen Verfahren zur Nutzbarmachung des Inhaltes von Abortgruben u. dergl. waren folgende:'The previous procedures for the utilization of the contents of lavatory pits and the like were the following:
1. Der Inhalt der Gruben wurde durch einen Zusatz von Kalk oder von Metallsalzen in einen festen und einen flüssigen Teil ,geschieden, der flüssige Teil auf Ammoniak verarbeitet und der feste Teil getrocknet und als Dünger verwendet (vergl. Heiden, Müller & Langsdorf, S. 71; Fischer, S. 53; Vogel, S. 392).1. The contents of the pits were made into one by adding lime or metal salts solid and a liquid part, divorced, the liquid part processed on ammonia and the solid part dried and used as fertilizer (cf. Heiden, Müller & Langsdorf, p. 71; Fischer, p. 53; Vogel, p. 392).
2. Die Masse schied sich in einen festen und flüssigen Teil auf mechanischem Wege. Abtreiben des Ammoniaks aus dem flüssigen Teil; Trocknen der festen Teile (vergl. Kerl-Stohmann, Bd."I, S. 879).2. The mass was mechanically separated into a solid and a liquid part. Abortion of ammonia from the liquid part; Drying the solid parts (see Kerl-Stohmann, Vol. "I, p. 879).
3. Die Masse wurde mit einer das gesamte Ammoniak bindenden Menge Schwefelsäure versetzt und dann getrocknet (vergl. Vogel, 1896, S. 346; Fischer, 1882, S. 56).3. The mass was treated with an amount of sulfuric acid which binds all the ammonia added and then dried (cf. Vogel, 1896, p. 346; Fischer, 1882, p. 56).
4. Durch Zusetzen von Säure wird die Masse in einen festen und einen flüssigen Teil zerlegt und die Seifen in Fettsäuren und Basen, dann wird die ganze Masse in Filterpressen abgepreßt und aus den Preßrückständen das Fett mittels Benzin ausgezogen und dann der Rückstand getrocknet (vergl. D. R. P. 122921, Kl. 16).4. By adding acid, the mass becomes broken down into a solid and a liquid part and the soaps into fatty acids and bases, then the whole mass is pressed out in filter presses and from the press residues that Extracted fat with gasoline and then dried the residue (cf. D. R. P. 122921, Class 16).
Die Verfahren unter 1., 2. und 3. sind im Betrieb zu teuer und vernachlässigen die Fettgewinnung. Das Verfahren unter 4. leidet darunter, daßThe processes under 1., 2. and 3. are too expensive to operate and neglect the production of fat. The procedure under 4. suffers from the fact that
a) die ganze Masse durch ihren Fettgehalt, selbst auch durch Schwefelsäurezusatz, schwer filtrierbar ist, da die abgeschiedenen Schwammteile eine Emulsion bilden;a) the whole mass is heavy due to its fat content, even due to the addition of sulfuric acid is filterable, since the separated sponge parts form an emulsion;
b) entstehen bei dem Arbeiten mit den Filterpressen, beim Entleeren usw., bevor,das Fett ausgeschieden ist, die Arbeiter und die Umgebung sehr belästigende, äußerst übelriechende Dünste;b) when working with the filter presses, when emptying, etc., before, the grease is created is excreted, the workers and the environment very annoying, extremely foul-smelling fumes;
c) geht bei dem Austreiben des Benzins, nach stattgehabter Fettauslaugung, aus der Masse, welches mittels direkten Dampfes geschehen muß, ein großer Teil des Stickstoffgehaltes des Rückstandes durch Ausdampfen verloren.c) goes out of the mass when the gasoline is driven out, after fat leaching has taken place, which must be done by means of direct steam, a large part of the nitrogen content of the Residue lost by evaporation.
Alle diese Übelstände vermeidet das nachstehend beschriebene Verfahren.The procedure described below avoids all of these inconveniences.
Die abgelagerte Masse wird erhitzt und dann in flüssigem Zustande in Ausiaugungsapparate gebracht und der gleichzeitigen Einwirkung von Benzin und geringen Mengen von Schwefelsäure unterworfen und so das Fett extrahiert. Die Ausiaugungsapparate sind mit Rührwerk versehen, welche die .Masse und das Benzin emulgieren. Ist die Extraktion beendet, so wird das Rührwerk stillgesetzt, so daß sich die Benzinfettlösung oben abscheidet, wo sie leicht abgelassen werden kann. Das Fett wird nun durch Abtreiben des Benzins in bekannter Weise in besonderen Apparaten gewonnen. Der in den Auslaugungsapparaten zurückbleibende Schlamm, welcher durch die Entfettung und die ganze Behandlung geruchlos ist, läßt sich nun leicht in Filterpressen abpressen, worauf dann die erhaltenen Preßkuchen getrocknet werden, um als Dünger oder sonstwie Ver-Wendung zu finden.The deposited mass is heated and then in a liquid state in leaching apparatus brought and the simultaneous action of gasoline and small amounts of sulfuric acid subjected and so the fat is extracted. The Ausiaugungsapparate are with agitator provided, which emulsify the mass and the gasoline. If the extraction is finished, so the agitator is stopped so that the gasoline grease solution separates out at the top, where it is easy can be drained. The fat is now known by driving off the gasoline in Way obtained in special apparatus. The one left in the leachers Sludge, which is odorless due to the degreasing and the whole treatment, can be removed now gently squeeze in filter presses, whereupon the press cake obtained is dried to be used as fertilizer or in any other way.
