Abstract

Drinking water production comprises carrying out waste water purification by zeolite filtration, removing heavy metals from raw water with at least a zeolite based cation exchanger using at least one natural adsorbent, removing nitrate and nitrite from the raw water with at least one regenerable exchange resin comprising anion exchanger, disinfecting the raw water including microorganism destruction by oxidants, which are generated by at least one diamond electrode during an anodic oxidation of water serving as electrolyte, and removing the oxidizing agents. Drinking water production comprises carrying out the waste water purification by zeolite filtration, removing heavy metals from the raw water with at least a zeolite based cation exchanger using at least one natural adsorbent, removing nitrate and nitrite from the raw water with at least one regenerable exchange resin comprising anion exchanger, disinfecting the raw water including microorganism destruction by oxidants, which are generated by at least one diamond electrode during an anodic oxidation of water serving as electrolyte, and removing the oxidizing agents from the raw water by activated charcoal filter filtration.

Description

Die Erfindung betrifft ein Verfahren zur Trinkwasser-Herstellung nach dem Oberbegriff des Anspruches 1.The invention relates to a method for producing drinking water according to the preamble of claim 1.

Beispielsweise werden bei bekannten Verfahren zum Reinigen von Abwasser sowie zum Herstellen von Trinkwasser aufwändig biologische Prozesse durch zusätzliche Reinigungsschritte ergänzt, wie DE10030984A1 verdeutlicht. Auch kommen bei bekannten Wasserreinigungsverfahren Chemikalien als Desinfektionsmittel ( DE 20 2006 006 857 U1 ) oder Chemikalien zur anderweitigen chemischen Wasserreinigung ( DE2742801A1 ) zum Einsatz. Derartige Chemikalienanwendung ist beim Aufbereiten von Wasser zum Lebensmittel Trinkwasser aus gesundheitlichen Gründen bedenklich und deshalb unerwünscht. Außerdem ist bekannt, dass zum energieautarken Realisieren von Wasserreinigungsverfahren Muskelkraft benutzt werden kann ( CH693415A ); wobei nachteilig ist, dass dann dauerhaft Bedienpersonal zur Verfahrensdurchführung benötigt wird.For example, in known methods for purifying wastewater and for producing drinking water, biological processes are supplemented by additional purification steps, such as DE10030984A1 clarified. Also come in known water purification processes chemicals as disinfectants ( DE 20 2006 006 857 U1 ) or chemicals for other chemical water purification ( DE2742801A1 ) for use. Such chemical application is critical in the treatment of water to food drinking water for health reasons and therefore undesirable. In addition, it is known that muscle energy can be used for energy self-sufficient realization of water purification processes ( CH693415A ); which is disadvantageous that then permanently operating personnel is required to carry out the process.

Aufgabe der Erfindung ist die Gestaltung eines Verfahrens zur Herstellung von Trinkwasser, das vergleichsweise geringen technischen Aufwand bedingt, keinen Chemikalienzusatz erfordert und energieautark ist. Somit kann die Trinkwasser-Herstellung kontinuierlich, stabil und durch Selbstversorgung mit Energie sehr wirtschaftlich erfolgen.The object of the invention is the design of a process for the production of drinking water, which requires relatively little technical effort, requires no addition of chemicals and is energy self-sufficient. Thus, the production of drinking water can be done continuously, stably and by self-sufficiency with energy very economically.

Diese Aufgabe wird mit einem Verfahren zur Trinkwasser-Herstellung gelöst, das gemäß den Merkmalen nach Anspruch 1 gestaltet ist. Das erfindungsgemäße Verfahren ermöglicht vorteilhaft Aufwandsreduzierung bei der Wasserreinigung und somit verbesserte Wirtschaftlichkeit dieses Prozesses. Es vermeidet auch die beschriebene Chemikalienanwendung und erlang energetische Autarkie durch alleinige Anwendung von regenerativer Energie. Ein bevorzugter Anwendungsbereich des Verfahrens ist deshalb die Trinkwasser-Herstellung in kompakten Anlagen, die sich gut für mobile Einsätze, insbesondere zur Trinkwasser-Versorgung bei Notsituationen, eignen.This object is achieved with a method for drinking water production, which is designed according to the features of claim 1. The inventive method advantageously allows cost reduction in water purification and thus improved efficiency of this process. It also avoids the described application of chemicals and achieves energy self-sufficiency by the sole application of regenerative energy. A preferred application of the method is therefore the production of drinking water in compact systems that are well suited for mobile use, in particular for drinking water supply in emergency situations.

Ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens ist das Herstellen von Trinkwasser aus Schmutzwasser mit folgenden fünf Verfahrensschritten, die nacheinander vom zu reinigenden Wasser aufgrund der Schwerkraftwirkung durchlaufen werden:
Zeolithfilter-Filtration, Schwermetallentfernung durch Zeolith basierten Kationen-Austauscher unter Mitverwendung eines natürlichen Adsorptionsmittels, Nitrat- und Nitritentfernung mit einem regenerierbaren, Austauscherharz beinhaltenden Anionen-Austauscher, Desinfektion einschließlich der Mikroorganismen-Zerstörung durch Oxidationsmittel, die vermittels einer fotovoltaisch mit Elektroenergie versorgten Diamantelektrode auf dem Wege anodischer Oxidation aus dem als Elektrolyt dienenden Wasser erzeugt werden, sowie Oxidationsmittel-Entfernung durch Aktivkohlefilter-Filtration.An embodiment of the method according to the invention is the production of drinking water from dirty water with the following five process steps, which are successively traversed by the water to be purified due to the force of gravity:
Zeolite filter filtration, heavy metal removal by zeolite-based cation exchanger with the use of a natural adsorbent, nitrate and nitrite removal with a regenerable, exchange resin-containing anion exchanger, disinfection including microorganism destruction by oxidizing agent, by means of a photovoltaic powered with electric diamond electrode on the Paths of anodic oxidation are generated from serving as the electrolyte water, and oxidizer removal by activated carbon filter filtration.
