Verfahren zum Herstellen von lagerbeständigen, geruchlosen und biologisch aktiven Bodenverbecserungsmitteln (Zusatz zum Patent 1 145 646)Process for the production of storable, odorless and biologically active soil improvers (Addition to patent 1 145 646)
Die Erfindung betrifft ein Verfahren zum Herstellen von lager be st and igen, geruchlosen und biologisch aktiven Boclonverbesserungsmitteln aus Abfallstoffen durch Aufbereiten und Trocknen von Gemischen aus Müll und Klärschlamm, bei welchem ein Gemisch aus teilweise entwässertem Klärschlamm, insbesondere Klärschlamm mit einem Wassergehalt unter 70 % und zerkleinertem Müll, insbesondere Müllraspelgut, einerThe invention relates to a process for the production of odorless and biologically active Boclon improvers from waste materials by processing and drying mixtures of garbage and sewage sludge, in which a mixture of partially dewatered sewage sludge, in particular sewage sludge with a water content below 70 % and shredded rubbish, in particular rubbish rubbish, a

Preßverformung unter starkem Verdichten der Masse auf bin zu etwa ein Drittel ihres Volumens ohne Wasseraustritt unterworfen wird und die so erhaltenen Preßlinge durch Lagern an der Luft getrocknet werden, nach Patent No. 1 l¥j> 646.Compression molding with strong compression of the mass to about a third of its volume is subjected to without leakage of water and the compacts obtained in this way are dried by storage in the air, according to patent no. 1 l ¥ j> 646.
Dem der deutschen Auslegeschrift No. 1 917 259 zugrundeliegenden Verfahren lässt sich entnehmen, das gepreßte MUllgemlsch durch Atmungsstöße künstlich zu belüften. Eine derartige Belüftung setzt das Verhandensein von entsprechend geeigneten Behältern sowie auch das anschließende Nachrotten auf Haufen oder in Mieten voraus.That of the German exposition No. 1 917 259 underlying Process can be found in the pressed garbage to ventilate artificially through breaths. Such ventilation implies the negotiation of appropriately suitable ones Containers as well as the subsequent rotting in piles or in heaps in advance.
Es liegt auf der Hand, daß sich die. zum Ausführen des Verfahrens nach der deutschen Auslegeschrift 1 917 2J59 recht aufwendigen Behälterbauten sowie der hierfür zusätzliche Platzbedarf ebenso nachteilig auswirken wie auch die notwendigen Krananlagen, um die Behälter beschicken und sodann wieder entleeren zu können. Zumindest unsicher ist damit auch der Reife- und Entseuchungsprozeß innerhalb einer Zeit von etwa 5 bis 4 Wochen; es steht mithin anzunehmen, daß dieser Reife- und Entseuchungsprozeß erst nach wesentlich längerem Lagern eintritt.It is obvious that the. to carry out the procedure according to the German Auslegeschrift 1 917 2J59 quite elaborate container structures as well as the additional ones for this Space requirements are just as disadvantageous as the crane systems required to load the containers and then again to be able to empty. The maturation and disinfection process within a time of about 5 to 4 weeks; it can therefore be assumed that this The process of maturation and disinfection does not occur until after much longer storage.

Im (Haupt-) Patent No. 1 145 646, in welchem das in der Fachwelt unter "Brikollare-Verfahren" bekannte Verfahren beschrieben ist, erfolgt das Entseuchen innerhalb von 3 bis 4 Wochen in belüfteten Stapeln oder aber mittels Luftkanälen in den einzelnen Müllsteinen bzw. -briketts. Nach dem Belüften erfolgt bei diesem Verfahren ein erneutes Befeuchten, damit das Material sodann auf Haufen oder in Mieten innerhalb relativ langer Zeit (etwa 4 bis 5 Monate) nachrotten kann.In (main) patent no. 1 145 646, in which that in the Process known to experts under the "Brikollare process" is described, the disinfection takes place within 3 up to 4 weeks in ventilated stacks or by means of air ducts in the individual rubbish stones or briquettes. To After aeration, this process is followed by renewed moistening, so that the material can then be stored in heaps or in heaps within a relatively long time (about 4 to 5 months) can rot.
Auch dieses Verfahren erfordert im praktischen Ablauf einen größeren Platzbedarf. Durch diesen wiederum sind unerwünschte Einwirkungen durch Witterungseinflüsse zu befürch-^ ten, da nicht immer in genügendem Umfang gedeckte Räumlichkeiten, wie Hallen od. dip., zur Verfügung stehen.This method also requires a larger amount of space in the practical process. As a result of this, in turn, undesirable effects from the effects of the weather are to be feared because there are not always enough covered rooms available, such as halls or dip.
Hier setzt nun das Wesen der vorliegenden Erfindung ein, die sich die Aufgabe gestellt hat, das VerfaKren nach dem (Haupt-) Patent 1 145 646 hinsichtlich der insoweit erkannten Unzulänglichkeiten zu verbessern.This is where the essence of the present invention begins, which has set itself the task of proceeding according to the (Main) patent 1,145,646 with regard to the recognized so far Improve inadequacies.
Gelöst wird diese Aufgabe im wesentlichen dadurch, daß die luftgetrocknete Preßlinge nach einer Lagerzeit von weniger als vier Wochen und nach Erreichen eines Kohlenstoff-Stick-This object is achieved essentially in that the air-dried compacts after a storage time of less than four weeks and after reaching a carbon stick

stoff-Verhältnisse von gleich oder kleiner 20 erneut zerkleinert und sodann in Korngrößen von weniger als 6 mm abgesiebt werden. pulp ratios equal to or less than 20 are crushed again and then sieved in grain sizes of less than 6 mm.
In weiterer Ausgestaltung der vorgeschlagenen Erfindung beträgt die Lagerzeit der luftgetrockneten Preßlinge etwa drei Wochen.In a further embodiment of the proposed invention, the storage time of the air-dried compacts is approximately three weeks.
Es ist einleuchtend und überzeugend zugleich, daß mit der vorgeschlagenen Erfindung eine Reihe von Vorteilen einhergeht. So sind nach der vorstehend erwähnten Verfahrens-Variante weder kostspielige und aufwendige Lagerbehälter-Bauten noch vielweniger ebensolche Kran- und Transportanlagen erforderlich; das zerkleinerte und abgesiebte Pein-, produkt kann demhingegen ohne weitere Behandlung, z. B. Nachreife, an den Verbraucher abgegeben werden. Die Abgabe kann, je nachBedarf, offen oder in Gebinden konfektioniert, erfolgen. Das fertige Produkt entspricht dabei erstklassigem Reifkompost, jedoch nicht etwa üblicher Pflanzerde.It is both illuminating and convincing that with the proposed invention is associated with a number of advantages. So are according to the variant of the method mentioned above neither costly and elaborate storage container constructions nor, much less, crane and transport systems necessary; the crushed and sieved torment, In contrast, the product can be used without further treatment, e.g. B. Nachrife, be given to the consumer. The levy can be open or packaged, depending on requirements. The finished product is first class Ripe compost, but not the usual potting soil.
