Abstract
Description
Die vorgelegte Erfindung betrifft Verfahren und Vorrichtungen zur Verminderung der Schadwirkung von Schadstoffen, Gefahrstoffen und/ oder Giftstoffen in Deponien, Ablagerungen, Böden und/oder Schläm men.The present invention relates to methods and devices for Reduction of the harmful effects of pollutants, hazardous substances and / or toxins in landfills, deposits, soil and / or sludge men.
Unter Schadwirkung, Schadstoffen, Gefahrstoffen und oder Giftstof fen sind Stoffe gemäß den Definitionen der Umweltschutzgesetzge bung zu verstehen, wie beispielsweise im Chemikalien-Gesetz oder in der Gefahrstoffverordnung.Taking harmful effects, pollutants, hazardous substances and or toxins fen are substances according to the definitions of the environmental protection law exercise to understand, such as in the Chemicals Act or in the Hazardous Substances Ordinance.
Zum Zwecke der Schadwirkungs-Verminderung werden die Schadstoffe, Gefahrstoffe und/oder Giftstoffe erfindungsgemäß durch Reaktionen mit geologischen, mineralogischen und/oder chemischen Stoffen, Ver bindungen und/oder Zubereitungen unter Verwendung geeigneter Vor richtungen versetzt. Vorzugsweise werden die geologischen, mine ralogischen und/oder chemischen Stoffe, Verbindungen und/oder Zu bereitungen in die schadstoff-, gefahrstoff- und/oder giftstoff haltigen Medien eingetragen, eingebracht und/oder eingemischt.For the purpose of reducing the harmful effects, the pollutants, Hazardous substances and / or toxins according to the invention by reactions with geological, mineralogical and / or chemical substances, ver bindings and / or preparations using suitable preparations directions offset. Preferably the geological, mine logical and / or chemical substances, compounds and / or zu Preparations in the pollutant, hazardous and / or toxic containing media entered, introduced and / or mixed.
Anhand einiger Beispiele sei das erfindungsgemäße Verfahren und Vorrichtungen kurz erläutert: The method according to the invention and Devices briefly explained:
Hier kann durch Eintragen geeigneter Gase, Flüssigkeiten und/oder Lösungen und/oder Feststoffe, vorzugsweise pul verisiert, die Löslichkeit der Schwermetalle durch chemi sche Reaktionen derart vermindert werden, so daß diese von Nutzpflanzen innerhalb einer Vegetationsperiode kaum auf genommen werden können.Here, by entering suitable gases, liquids and / or solutions and / or solids, preferably pul verifies the solubility of heavy metals through chemi cal reactions are reduced so that these of There are hardly any crops within a growing season can be taken.
Die Schadwirkung von Schadstoffen, vorzugsweise Schwerme tallen (bzw. Schwermetallionen), kann durch Aufbringen und/ oder Einarbeiten mineralogischer und/oder chemischer Stoffe, Verbindungen und/oder Zubereitungen, die zusammen mit dem Luftsauerstoff, der Kohlendioxid und/oder den Bodenbakterien oxidierend, reduzierend und/oder anderweitig reagieren, vermindert werden.The harmful effects of pollutants, preferably heavy substances tallen (or heavy metal ions), can by application and / or incorporation of mineralogical and / or chemical substances, Compounds and / or preparations together with the Atmospheric oxygen, carbon dioxide and / or soil bacteria react oxidizing, reducing and / or otherwise, can be reduced.
Das Aufbringen und/oder Einarbeiten der wirksamen Stoffe, Verbindungen und/oder Zubereitungen kann Monate vor der Aus saat und/oder nach der Ernte erfolgen.The application and / or incorporation of the active substances, Compounds and / or preparations can months before the end seeds and / or after harvest.
Zum Aufbringen und/oder Einarbeiten von Flüssigkeiten und/ oder streufähigen Feststoffen eignen sich Vorrichtungen, die bei der landwirtschaftlichen Bearbeitung von Nutzflächen Stand der Technik sind.For applying and / or incorporating liquids and / or scatterable solids are devices that in the agricultural processing of usable areas State of the art.
Die im Boden enthaltenen Schadstoffe, Gefahrstoffe und/oder Giftstoffe sowie Schwermetalle (bzw. Schwermetallionen) dringen pro Jahr bis zu fünfzig Zentimeter in größere Tiefen des Bodens ein.The pollutants, hazardous substances and / or contained in the soil Toxins and heavy metals (or heavy metal ions) penetrate to greater depths of up to 50 centimeters a year of the ground.
Beschleunigt werden diese Vorgänge durch Auftreten von saurem Regen, der zuweilen Säuregrade bis zu p H =3.5 erreichen kann.These processes are accelerated by the occurrence of acid rain, which can sometimes reach acid levels up to p H = 3.5.
Durch Einbringen geologischer, mineralogischer und/oder che mischer Schutzschichten oberhalb des Grundwassers kann das Eindringen der Schadstoffe in das Grundwasser verhindert oder wenigstens auf ein Tausendstel bis ein Millionstel der Schad stoffgehalte verringert werden.By introducing geological, mineralogical and / or mixer protective layers above the groundwater can do that Prevents pollutants from entering the groundwater or at least to a thousandth to a millionth of the damage content can be reduced.
Diese Schutzschichten lassen sich kostengünstig in all den Fällen einbringen und anlegen, wo bis in diese Tiefen Boden aushub notwendig wird. Dies ist bei der Förderung von Erzen und Kohle im Tagebau sowie bei Altlasten-Sanierung von Depo nien gegeben.These protective layers can be inexpensively used in all of them Bring in cases and create where down to this depth excavation becomes necessary. This is when mining ores and coal in the opencast mine as well as in the remediation of contaminated sites from Depo never given.
In all den Fällen, in denen eine Abtragung der Böden unmög lich und/oder zu hohe Kosten verursacht, kann mit speziellen Vorrichtungen durch Einbringen von bestimmten Gasen im Boden eine Schutzschicht für das Grundwasser aufgebaut werden.In all cases in which the soil cannot be removed Lich and / or too high costs can be caused with special Devices by introducing certain gases into the soil a protective layer for the groundwater can be built up.
Bei der Anlage von Deponien können geologische, mineralogi sche und/oder chemische Schichten zum Schutze des Grundwas sers aufgebaut werden.When creating landfills, geological, mineralogi chemical and / or chemical layers to protect the groundwater be built up.
Mit Hilfe von Tiefbohrungen lassen sich in eine bestehende Deponie gasführende Lanzen niederbringen, über die mit einem bestimmten Gas absteigende Schadstoffe, vorzugsweise Schwer metalle (bzw. Schwermetallionen), zur Bildung einer Schutz schicht gezwungen werden können. With the help of deep drilling can be in an existing Bring landfill gas-carrying lances down, over which with a certain gas descending pollutants, preferably heavy metals (or heavy metal ions), to form a protection shift can be forced.
Alle Maßnahmen dieser Art, über die bereits eine Reihe von Pilot ergebnisse vorliegen, müssen wissenschaftlich betreut und beglei tet werden und bedürfen umfangreicher chemischer Analysen vor und während der gesamten Betriebszeit.All measures of this type have already been piloted Results must be scientifically supervised and supported and require extensive chemical analyzes before and during the entire operating time.
Alle hierzu notwendigen Vorrichtungen sind den Gegebenheiten und Anforderungen anzupassen und entsprechend einzusetzen.All devices necessary for this are the conditions and Adapt requirements and use them accordingly.
