Abstract
Description
Die Entsorgung der Städte und Gemeinden von Abfällen aller Art wird in steigendem Maße schwieriger. Über füllte Deponien und das zunehmende Problem, das biolo gische Abfälle auf Haus- und Gewerbemülldeponien durch Sickerwasser und Gasbildung bereiten, haben bereits zu einem Umdenken geführt und zu einer, durch Gesetze und Verordnungen erzwungene Trennung von biologischen Abfällen geführt. Die Rückführung biologischer Abfälle in den Stoffkreislauf ist insbesonders, wenn keine weitere Kontamination durch Fremdstoffe vorliegt, weitgehend unproblematisch und im wesentlichen ein Kostenfaktor, der allerdings wiederum durch Gebühren, die von den Städten und Gemeinden bzw. Entsorgungsun ternehmen erhoben werden, von den Abfallerzeugern zu tragen sind. Eine Akzeptanz der Gebühren wird am ehe sten dann erreicht, wenn die Entsorgung so kostengün stig wie möglich erfolgt.The disposal of cities and municipalities of waste of all kinds is becoming increasingly difficult. About filled landfills and the increasing problem, the biolo wastes on domestic and commercial landfills Leachate and gas formation have already closed led to a rethink and to one, through laws and Regulations enforced separation from biological Waste. The recycling of biological waste is particularly in the material cycle if none there is further contamination from foreign substances, largely unproblematic and essentially one Cost factor, which in turn is due to fees, by the cities and municipalities or waste disposal companies are raised by the waste producers are wearing. The fees will be accepted on Most achieved when disposal is so inexpensive done as possible.
Die zur Zeit üblichen Verfahren der Verwertung biologi scher Abfälle laufen folgendermaßen ab: vom Hausmüll getrennte Erfassung, Transport zur Verwertungsstelle, manuelles Auslesen von Fremdstoffen und anschließende Kompostierung, mehrmaliges Umsetzen und nach einer Rottezeit von ca. drei Monaten Abgabe zur Bodenverbes serung an die Land- bzw. Gartenwirtschaft usw. Dies trifft auch zu für die Kompostierung von Gülle, Klär schlamm, Fäkalie und ihren Mischungen. The currently usual methods of recycling biologically wastes are as follows: from household waste separate recording, transport to the recycling center, manual reading of foreign substances and subsequent Composting, repeated repositioning and after one Rotting time of about three months delivery to the soil survey Agriculture, horticulture, etc. This also applies to the composting of liquid manure, sewage mud, faeces and their mixtures.
Durch die lange Rottezeit ist der Flächenbedarf erheb lich, außerdem findet eine nicht zu vernachlässigende Geruchsbelastung der Umgebung statt. Der normalerweise hohe Feuchtigkeitsgehalt biologischer Abfälle wie Küchenabfälle, Speisereste, überlagerte und verdorbene Lebensmittel, Fäkalie usw. kann dabei zu Sickerwässern führen, die wiederum aufgefangen und fachgerecht ge klärt werden müssen.Due to the long rotting time, the area requirement is considerable Lich, also finds a not to be neglected Odor pollution in the environment instead. Usually high moisture content of biological waste such as Kitchen waste, leftovers, overlaid and spoiled Food, faeces, etc. can cause seepage water lead, which in turn is collected and ge need to be clarified.
Probleme können ebenfalls durch phytopathogene Keime entstehen, die bei der herkömmlichen Kompostierung nur ungenügend abgetötet werden und bei der Verwertung des fertigen Kompostes Pflanzenkrankheiten weiter verbrei ten können. Der hohe Salzgehalt (Nitrate, Sulfate u. a.) kann Probleme bei der Nutzung und Verwertung der Kompo ste nachsichziehen.Problems can also be caused by phytopathogenic germs arise that only with conventional composting insufficiently killed and in the recovery of the finished compost plant diseases spread can. The high salt content (nitrates, sulfates, etc.) can have problems with the use and recovery of the compo follow up.
Die vorliegende Erfindung betrifft ein Verfahren, bei dem biologische Abfälle so aufbereitet werden, daß sie entweder unmittelbar auf Felder als Naturdünger ausge bracht werden können oder nach einer kurzen Rottezeit von max. 1 Monat als hochwertiger, weitgehend keimfrei er Humus zu verwenden sind mit einem akzeptablen Salz gehalt unterhalb des Grenzwertes bzw. mineralisiert.The present invention relates to a method in biological waste is processed so that it either directly on fields as natural fertilizer can be brought or after a short rotting time by Max. 1 month as a high-quality, largely germ-free he humus are to be used with an acceptable salt content below the limit or mineralized.
Der Verfahrensablauf ist im folgenden erläutert. Die biologischen Abfälle werden angeliefert, durch ein Förderband in einen Vorratscontainer transportiert und dabei gleichzeitig manuell von Fremdstoffen wie Fla schen usw. ausgelesen. Aus dem Vorratscontainer werden die Abfälle einem vorzugsweise Doppelschneckenextruder zugeführt und je nach Feuchtigkeit, Zusammensetzung usw. dosiert, grob geschredderte Holzabfälle wie Bau holz, Baumschnitt, Rindenabfälle, Durchforstungsholz usw. zugegeben. In dem Doppelschneckenextruder wird der biologische Abfall mit den Holzabfällen intensiv ge mischt, geknetet, zerrieben und einem Druck bis zu 1000 bar ausgesetzt. Dabei steigt die Temperatur auf weit über 100 Grad C, so daß sämtliche Keime, Viren, Bakte rien, Unkrautsamen mit Sicherheit abgetötet werden. Am Austritt des Extruders findet eine schlagartige Ent spannung auf Normaldruck statt, wobei das im Abfall und in den Holzzellen befindliche Wasser explosionsartig verdampft und noch vorhandene Holzteile völlig zerfa sert. Das austretende Gemisch hat dann eine krümelige Konsistenz, ist im Volumen reduziert und kann bereits unmittelbar als Naturdünger ausgebracht werden. Um als Pflanzsubstrat bzw. Gartenerde verwendet zu werden, genügt auf Grund der Aufbereitung und des Fehlens gröberer Bestandteile eine Rottezeit von max. 1 Monat. Die Geruchsbelästigung der Umgebung ist gegenüber anderer Verfahren sehr gering, so daß eine Aufstellung der Anlage in Gewerbegebieten möglich ist.The procedure is explained below. The biological waste is delivered through a Conveyor belt transported in a storage container and while manually removing foreign substances such as fla read out etc. The storage container becomes the waste is preferably a twin-screw extruder fed and depending on moisture, composition etc. dosed, roughly shredded wood waste such as construction wood, pruning, bark waste, thinning wood etc. admitted. In the twin screw extruder biological waste with the wood waste intensively ge mixes, kneaded, grated and a pressure up to 1000 exposed to bar. The temperature rises far over 100 degrees C, so that all germs, viruses, bacteria rien, weed seeds are sure to be killed. At the Exit of the extruder finds an abrupt Ent voltage to normal pressure instead, which in the waste and Explosive water in the wooden cells evaporated and still existing wooden parts completely sert. The emerging mixture then has a crumbly one Consistency is reduced in volume and can already are applied directly as natural fertilizer. To as Plant substrate or garden soil to be used, is sufficient due to the preparation and the lack coarser components a rotting time of max. 1 month. The smell of the environment is opposite other procedures very low, so a list the investment in commercial areas is possible.
In der Gesamtkostenbilanz wird der Maschinenaufwand durch den wesentlich geringeren Flächenbedarf für Kompostmieten und der hohen Qualität des erzeugten Produktes zu einem untergeordneten Faktor. Die Kosten einsparung gegenüber anderer Verfahren liegt ca. 50%.In the total cost balance, the machine expenditure due to the much smaller space requirement for Compost rents and the high quality of the produced Product to a subordinate factor. The cost saving compared to other processes is approx. 50%.
