Abstract
Bekannt ist es, insbesondere zur Abtrennung von Arsen aus Wasser ein Absorptionsverfahren anzuwenden. Durch Auswahl eines geeigneten Absorptionsmittels durch eine Prozessführung mit integrierter Desorption ist eine kontinuierliche Regeneration der eingebrachten Flüssigkeit, insbesondere von Arsen belastetem Wasser, möglich. Bei der zugehörigen Vorrichtung ist dazu wenigstens eine Mischstufe (10) und eine Fest-Flüssig-Trennstufe (20) vorhanden. Gegebenenfalls können die Mischstufe (10) und die Fest-Trennstufe (20) eine gemeinsame Einheit bilden.It is known to use an absorption process in particular to separate arsenic from water. By selecting a suitable absorbent through process control with integrated desorption, continuous regeneration of the liquid introduced, in particular water contaminated with arsenic, is possible. The associated device has at least one mixing stage (10) and one solid-liquid separation stage (20). The mixing stage (10) and the solid separation stage (20) can optionally form a common unit.
Description
Die Erfindung bezieht sich auf ein Verfahren zur Beseitigung von Schadstoffen aus Trink-, Brauch- und Industriewässern, insbesondere von Schwermetallen aus Trinkwasser. Daneben bezieht sich die Erfindung auch auf die zugehörige Vorrichtung zur Durchführung des Verfahrens.The The invention relates to a method for removing pollutants from drinking, industrial and industrial waters, in particular from heavy metals from drinking water. In addition, the invention also relates to the associated Apparatus for carrying out of the procedure.
Zur Abtrennung von gelösten toxischen Stoffen aus Grund-, Prozess- und Trinkwasser werden bisher üblicherweise Verfahren wie beispielsweise Ionenaustausch, chemische Ausfällung, Filtration („Reverse Osmose”), Destillation od. dgl. eingesetzt. Bekannt sind weiterhin Methoden, die auf der Absorption an spezifischen Adsorptionsmitteln beruhen, die typischerweise in einem Festbettreaktor in einem diskontinuierlichen Prozess durchgeführt werden.to Separation of dissolved Toxic substances from groundwater, process water and drinking water have traditionally been used Methods such as ion exchange, chemical precipitation, filtration ("Reverse Osmosis"), Distillation od. Like. Used. Methods are still known, which are based on the absorption of specific adsorbents, the typically in a fixed bed reactor in a batch Process performed become.
Als toxischer Schadstoff bzw. Schwermetall ist derzeit insbesondere Arsen (As) im Fokus der Diskussion, wobei beispielsweise eine hohe Arsenbelastung im Trinkwasser in Indien und Bangladesh zu finden sind, was negative Langzeitfolgen für die Bevölkerung hat. Auch andere Metalle aus der Arsengruppe im Periodensystem, wie beispielsweise Selen, fallen unter die gleichen Betrachtungen.When toxic pollutant or heavy metal is currently particular Arsenic (As) in the focus of discussion, for example, a high To find arsenic pollution in drinking water in India and Bangladesh are what has negative long-term consequences for the population. Also other metals from the arsenic group in the periodic table, such as selenium, fall under the same considerations.
In der parallelen Patentanmeldung der Anmelderin mit gleicher Anmeldepriorität werden Vorschläge gemacht, das Arsen mittels Adsorptionsmaterialien zu binden. Dabei kommt es insbesondere auf die Aufbereitung des Adsorptionsmittels an, wobei dort spezifische Vorschläge zur magnetischen Separation und zur Wiederverwertung des Adsorptionsmittels gemacht werden. Es werden dort also zusätzlich magnetische Substanzen in das Verfahren eingebracht.In the applicant's co-pending patent application having the same filing priority proposals made to bind the arsenic by means of adsorption materials. there it comes in particular on the treatment of the adsorbent where there are specific proposals for magnetic separation and to be recycled to the adsorbent. It will be there in addition introduced magnetic substances in the process.
Aufgabe vorliegender Erfindung ist es demgegenüber, ohne derartige magnetische Substanzen auszukommen und nur durch mechanische Behandlung für eine geeignete Bereinigung von insbesondere Trinkwasser zu sorgen.task In contrast, the present invention is without such magnetic Substances get along and only by mechanical treatment for a suitable Clean up of drinking water in particular.

Bei der Erfindung erfolgt ebenso wie bei der parallelen Anmeldung eine Überführung des an sich bekannten Adsorptionsprozesses, welcher typischerweise diskontinuierlich betrieben wird, in ein kontinuierliches Verfahren. Dies ist durch die Kombination geeigneter Prozessschritte und Merkmale in der zugehörigen Vorrichtung möglich.at The invention takes place as in the parallel application, a transfer of the known adsorption process, which is typically discontinuous is operated in a continuous process. This is through the combination of suitable process steps and features in the associated device possible.
Insgesamt ergibt sich damit ein praxisgerechtes und servicearmes Verfahren, wobei vorteilhafterweise magnetisierbare Substanzen und entsprechende Vorrichtungen für die Trennung der magnetischen Substanzen nicht erforderlich sind.All in all This results in a practice-oriented and service-poor method, where advantageously magnetizable substances and corresponding Devices for the separation of the magnetic substances are not required.
