Abstract

In cleaning contaminated soil, the soil is mixed with CaO and reacted with H2O2. Contaminated ground water can also be treated. The appts. is claimed. ADVANTAGE - The process is effective and economical, and does not impose further load on the environment.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Reinigung verunreinigter Böden und Gewässer (Grundwasser), wobei die verunreinigten Böden und Gewässer durch Oxidation oder Reduktion während eines Waschvorganges von den ihnen anhaftenden oder in Lösung befindlichen Schadstoffen befreit werden.The invention relates to a method and a Device for cleaning contaminated floors and Bodies of water (groundwater), the contaminated soil and waters through oxidation or reduction during a washing process from the adherent or in them Solution pollutants are freed.

Die ständig zunehmende Verunreinigung von Boden und Grundwasser durch Schadstoffe chemischer Verbindungen beispielsweise, stellen eine ernste Bedrohung für die ökologischen und biologischen Naturgesetze dar. Der Mensch übt nicht nur Verrat an der wunderbaren Simbiose in seiner natürlichen Umwelt, in dem er insbesondere den Lebewesen ihren Lebensraum vergiftet, die eigentlich zum gegenseitigen Nutzen seinen besonderen Respekt verdienen, er übt auch wissentlich Verrat an der Wissenschaft, deren Wirkungsmechanismen, ganz besonders in der Chemie, fast bis zu den Alchimisten hin bekannt sind.The ever increasing pollution of soil and Groundwater due to pollutants from chemical compounds for example, pose a serious threat to the ecological and biological laws of nature. Man doesn't just betray the wonderful Simbiosis in its natural environment in which it poisoned their living space in particular, its actually for mutual benefit its special Earn respect, he also knowingly practices treason science, its mechanisms of action, quite especially in chemistry, almost up to the alchemists are known.

So werden die Erneuerungskräfte der Natur vorsätzlich zerstört, die verunreinigten Bodenschichten und Grund­ wässer sterben einen buchstäblichen Erstickungstod, der allmählich wie in den Weltmeeren, in immer tieferen Schichten anzutreffen ist. In this way, the forces of renewal are deliberate destroyed, the contaminated soil layers and ground water die a literal asphyxiation, gradually like in the oceans, in ever deeper ones Layers can be found.  

Zwar sind inzwischen Methoden und Verfahren zur Grund­ wasserreinigung weitgehend Stand der Technik, bei der Sanierung verunreinigter Böden jedoch, spendet die Forschung und Entwicklung vorerst noch erhebliche Geld- und Zeitmengen um der Bedrohung Herr zu werden. Vereinzelt sind aber auch schon Bodenreinigunsver­ fahren erfolgreich im Einsatz, die mit großem technischen Aufwand und beträchtlicher Energieinvestition arbeiten.Methods and procedures are now the reason water purification largely state of the art in which Remediation of contaminated soils, however, donates the Research and development still substantial for the time being Amounts of money and time to deal with the threat. But there are also occasional floor cleaning services drive successfully in use, with great technical Effort and considerable energy investment.

Zumeist handelt es sich um Waschverfahren mit thermischer Nachbehandlung, wie beispielsweise durch AB-Umwelt­ technik in Lägerdorf/Schleswig Holstein, oder um reine thermische Verfahren wie bei der Phytec Düsseldorf, beide Anbieter befinden sich noch in der Anwendungs­ vorbereitung. Als nachteilig empfunden wird fast immer der schon erwähnte technische Gigantismus und die Immobilität.Mostly it is a washing process with thermal Post-treatment, such as by AB environment technology in Lägerdorf / Schleswig Holstein, or around pure thermal processes like at Phytec Düsseldorf, both providers are still in use preparation. It is almost always felt to be disadvantageous the technical gigantism already mentioned and the Immobility.

Die Erfindung hat sich daher die Aufgabe gestellt, erkennbare Nachteile zuvor erwähnter Techniken weit­ gehend auszuschalten und den Stand der Technik so zu verbessern, daß der Einsatz von Bodenreinigungsver­ fahren und Vorrichtungen als effektiv, wirtschaftlich und die Umwelt nicht zusätzlich belastend beschrieben werden kann.The object of the invention is therefore to recognizable disadvantages of the previously mentioned techniques going to turn off and the state of the art improve that the use of floor cleaning ver drive and fixtures as effective, economical and not described the environment as an additional burden can be.

Erfindungsgemäß wird die gestellte Aufgabe dadurch ge­ löst, daß eine mobile, technische Einrichtung derart ausgestattet ist, daß sie an einem Einsatzort das durch Analyse angezeigte, verunreinigte Erdreich vereinnahmt, in einem Aufbereitungsverfahren reinigt und als voll­ wertiges Verfüllmaterial zurücksetzt. Ein nachfolgendes Ausführungsbeispiel, soll gleichzeitig als schematische Darstellung eines Arbeitsablaufes, das Zusammenspiel Verfahren und Vorrichtung deutlich machen.According to the invention the object is thereby ge solves that a mobile, technical facility such is equipped that the through at a site Analysis of contaminated soil displayed, cleaned in a reprocessing process and as full resets valuable backfill material. A subsequent embodiment is said to be simultaneous as a schematic representation of a workflow, the interaction between the process and the device is clear do.

So zeigt (1) die Entnahme eines belasteten Bodens und die Beschickung einer Drehtrommel (2) sowie die Schütt- und Dosierungsvorrichtung für CaO und Ca(OH)2 über der Drehtrommel (2). Von dem auf einer Bühne stehenden Tank (3) wird das in diesem Tank (3) befindliche 30%iges H2O2 dosiert dem Mischgut in der Drehtrommel (2) zu­ geführt. Das spontan bei der Reaktion entstehende Gasgemisch wird durch den Aktivkohlefilter (4) gereinigt und kann bedenkenlos an die Umgebung abgegeben werden. Die nach der Reaktion gereinigte Aufschlämmung in der Drehtrommel (2) wird mit Wasser nachgewaschen das über Filter (5) angeführt wird. Das durch Oxidation und Reduktion gereinigte Erdgut wird feucht am Arbeits­ bereich deponiert und nach Beendigung der Bodenreinigungs­ prozesse dem Erdreich als Verfüllmaterial wieder zugeführt.Thus ( 1 ) shows the removal of a loaded soil and the loading of a rotating drum ( 2 ) as well as the pouring and dosing device for CaO and Ca (OH) 2 above the rotating drum ( 2 ). From the tank ( 3 ) standing on a stage, the 30% H 2 O 2 present in this tank ( 3 ) is metered to the mix in the rotary drum ( 2 ). The gas mixture that arises spontaneously during the reaction is cleaned by the activated carbon filter ( 4 ) and can be safely released into the environment. The slurry in the rotary drum ( 2 ) cleaned after the reaction is washed with water which is passed through the filter ( 5 ). The soil, cleaned by oxidation and reduction, is deposited moist in the work area and returned to the soil as backfill material after the floor cleaning processes have been completed.
