Abstract
Description
Die Erfindung betrifft ein Verfahren zur Behandlung von biologisch behandeltem Abfall, insbesondere zur Behandlung von mechanisch-biologisch behandeltem Abfall.The invention relates to a method for the treatment of biologically treated waste, in particular for the treatment of mechanical-biological treated waste.
Bei dem biologisch behandelten Abfall oder mechanisch-biologisch behandelten Abfall handelt es sich insbesondere um Abfall, der in einem geschlossenen Behälter unter Zwangsbelüftung biologisch stabilisiert worden ist. Der biologische Stabilisierungsprozeß kann in einem geschlossenen Behälter, der auch als "Rottebox" bezeichnet werden kann, innerhalb eines bestimmten Zeitraums von beispielsweise sieben Tagen erfolgen. Das Material kann vor dem Einbringen in die Rottebox aufbereitet und/oder zerkleinert wer den. Ferner kann das Material während der biologischen Stabili sierung erstmals oder erneut zerkleinert werden (Zwischenzerklei nerung; dynamischer Zwischenschritt). Danach wird die biologi sche Stabilisierung fortgesetzt (zweifacher Boxendurchgang). Es ist ferner möglich, das Material vor und/oder während und/oder nach der biologischen Stabilisierung zu befeuchten.For biologically treated waste or mechanical-biological Treated waste is especially waste that biological in a closed container with forced ventilation has been stabilized. The biological stabilization process can be stored in a closed container, also known as a "rotting box" can be referred to within a certain period of time for example, seven days. The material can before Prepared and / or shredded into the rotting box the. Furthermore, the material during the biological stabili be shredded for the first time or again (intermediate shredding change; dynamic intermediate step). After that, the biologi stabilization continued (double box passage). It it is also possible to use the material before and / or during and / or to moisturize after biological stabilization.
Vorteilhaft ist es, das Material in einem dynamischen Zwischen schritt abzusieben, beispielsweise bei einem Siebschnitt von 40 bis 80 mm. Der Siebdurchgang kann anschließend durch eine Zer kleinerungsanlage geführt und bei Bedarf nachbefeuchtet werden. Der Siebüberlauf kann direkt zu Ballen verpreßt werden.It is advantageous to use a dynamic intermediate material sieve step, for example with a sieve cut of 40 up to 80 mm. The sieve passage can then by a Zer small system and be rewetted if necessary. The screen overflow can be pressed directly into bales.
Es ist möglich, den Abfällen, die mechanisch-biologisch behan delt werden sollen, zunächst weitere Stoffe zuzumischen. Durch eine gezielte Aufnahme unterschiedlicher Eingangsmaterialien kann eine Vermischung und/oder Vergleichmäßigung des Materials erzielt werden. Es ist möglich, grobe Störstoffe zu entfernen.It is possible to treat the waste mechanically and biologically should first be mixed in further substances. By a targeted inclusion of different input materials can mix and / or homogenize the material be achieved. It is possible to remove coarse contaminants.
Vorzugsweise wird das Material zunächst mechanisch aufgeschlos sen. Hierdurch werden große Oberflächen für den folgenden Rotte prozeß geschaffen und genügend Angriffsflächen für die Rotteor ganismen zur Verfügung gestellt. Ferner wird eine hohe Homogeni tät der unterschiedlichen Ausgangsstoffe gewährleistet und eine gute Belüftbarkeit sichergestellt.The material is preferably first mechanically unlocked sen. This creates large surfaces for the following rotting Process created and enough attack surfaces for the Rotteor mechanisms provided. Furthermore, a high homogeneity guaranteed the different starting materials and a good ventilation ensured.
Zum mechanischen Aufschluß kann ein Schredder verwendet werden, der das Material auf eine bestimmte Korngröße von beispielsweise weniger als 250 mm zerkleinert. Es ist möglich, Klärschlamm, vor zugsweise über eine Auflockerungs- und Dosiereinrichtung, dem zerkleinerten Abfall nach dem Schredder zuzugeben. Vorzugsweise wird das Material anschließend in eine Misch- und Homogenisie rungstrommel eingebracht.A shredder can be used for mechanical digestion of the material to a certain grain size, for example crushed less than 250 mm. It is possible to sewage sludge, before preferably via a loosening and metering device, the add shredded waste after the shredder. Preferably the material is then mixed and homogenized tion drum introduced.
Anschließend wird das Material in einem geschlossenen Behälter (Rottebox) unter Zwangsbelüftung kompostiert bzw. biologisch behandelt. In der luftdicht und flüssigkeitsdicht abgeschlos senen Rottebox erfolgt eine biologische Stabilisierung.The material is then placed in a closed container (Compost box) composted or forced under forced ventilation treated. Locked in the airtight and liquidtight The rotting box undergoes biological stabilization.
Vorzugsweise wird das Material dabei auf einen Feuchtigkeits gehalt von 15% oder weniger getrocknet. Ein solches Material kann als "Trockenstabilat" bezeichnet werden, da es verhältnis mäßig trocken und biologisch stabil ist.The material is preferably applied to moisture content of 15% or less dried. Such a material can be called "dry stabilate" because it is ratio is moderately dry and biologically stable.
In bestimmten Anwendungsfällen ist es wünschenswert oder erfor derlich, den biologisch behandelten Abfall bzw. den mechanisch- biologisch behandelten Abfall zu trocknen.In certain applications it is desirable or necessary the biologically treated waste or the mechanically dry biologically treated waste.
Aufgabe der Erfindung ist es, ein verbessertes Verfahren zur Behandlung von biologisch behandeltem Abfall bzw. von mechanisch- biologisch behandeltem Abfall vorzuschlagen.The object of the invention is to provide an improved method for Treatment of biologically treated waste or mechanical to propose biologically treated waste.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der bio logisch behandelte Abfall bzw. der mechanisch-biologisch behan delte Abfall mit Mikrowellen bestrahlt wird. Hierdurch wird der Abfall getrocknet. Zusätzlich zur Trocknung kann auch ein Hygie nisierungseffekt erreicht werden. Ferner ist es möglich, durch die Bestrahlung mit Mikrowellen einen Pyrolysevorgang einzulei ten oder zu beschleunigen, insbesondere wenn das Material ver dichtet ist.According to the invention this object is achieved in that the bio logically treated waste or mechanically-biologically treated delte waste is irradiated with microwaves. This will Waste dried. In addition to drying, it can also be a hygiene nization effect can be achieved. It is also possible to the irradiation with microwaves initiate a pyrolysis process or accelerate, especially if the material ver is sealed.
Eine vorteilhafte Weiterbildung des Verfahrens ist dadurch ge kennzeichnet, daß metallhaltige Teile des Abfalls vor der Be strahlung mit Mikrowellen zerkleinert werden. Wenn sich in dem Abfall bzw. dem vorbehandelten Abfall metallhaltige Teile befin den, beispielsweise Folien, die Metall enthalten, führt dies bei der Bestrahlung mit Mikrowellen zu einer Zündung (Entflammung). Diese Entflammungen sind nur dann unschädlich, wenn die Metall teile verhältnismäßig klein sind. Aus diesem Grund werden die Folien und sonstigen metallhaltigen Teile vor dem Einbringen in das Mikrowellengerät zerkleinert, was durch geeignete Zerklei nerungswerkzeuge wie beispielsweise Kugelmühlen, Zahnscheiben mühlen oder ähnliches geschehen kann. Insbesondere können Vor richtungen verwendet werden, die auch bei der Braunkohlenvermah lung und bei sonstigen Kohleaufbereitungen Anwendung finden.An advantageous development of the method is ge indicates that metal-containing parts of the waste before loading radiation with microwaves. If in that Metal or parts containing pretreated waste This, for example foils that contain metal, leads to this the radiation with microwaves to an ignition (ignition). These inflammations are only harmless if the metal parts are relatively small. For this reason, the Foils and other metal-containing parts before being introduced into the microwave is crushed, which is done by suitable crushing tools such as ball mills, toothed disks grind or something similar can happen. In particular, can directions are used that are also in the lignite mine treatment and other coal processing.
