Abstract
Insbesondere Industrieabwasser enthalten häufig organische Bestandteile als Schadstoffe. Solche organischen Schadstoffe können bekannterweise durch Anwendung elektrochenmischer Verfahren beseitigt werden, wozu Sauerstoff benötigt wird. Für die Praxis ist ein so genannter CSB-Wert (chemischer Sauerstoffbedarf) definiert, der von der Industrie eingehalten werden muss. Gemäß der Erfindung werden die organischen Schadstoffe zunächst aufkonzentriert und wird anschließend die Flüssigkeit mit den aufkonzentrierten Schadstoffen einer Elektrodialyse unterzogen. Damit ergibt sich insgesamt ein beachtlich verringerter Energiebedarf. Bei einer für dieses Verfahren geeigneten Anlage ist der Einrichtung für die Elektrodialyse vorteilhafterweise eine erste Einrichtung nach dem Filtrationsprinzip und eine zweite Einrichtung nach dem "Reverse Osmose-Prinzip" vorgeschaltet.Industrial wastewater in particular often contains organic components as pollutants. As is known, such organic pollutants can be removed by using electro-mechanical processes, for which oxygen is required. In practice, a so-called COD value (chemical oxygen demand) is defined which industry must adhere to. According to the invention, the organic pollutants are first concentrated and then the liquid with the concentrated pollutants is subjected to electrodialysis. Overall, this results in a considerably reduced energy requirement. In a system suitable for this method, the device for electrodialysis is advantageously preceded by a first device based on the filtration principle and a second device based on the "reverse osmosis principle".

Bekannt ist es, derartige Schadstoffe durch elektrochemische Oxidation zu beseitigen oder zumindest zu verringern.industrial Wastewater is known to be a high proportion of organic pollutants. It is known, such pollutants by electrochemical oxidation to eliminate or at least to reduce.
Vom Stand der Technik ist der oxidative Abbau von sauerstoffzehrenden organischen Verbindungen aus Industrieabwässern bekannt. Die Summe dieser organischen Verbindungen wird im so genannten CSB-Wert (CSB = Chemischer-Sauerstoff-Bedarf) erfasst. Für diesen Summenparameter (CBS) existiert für die Industrie ein Einleitegrenzwert.from State of the art is the oxidative degradation of oxygen-consuming organic compounds known from industrial wastewater. The sum of these organic compounds is in the so-called COD value (COD = chemical oxygen demand) recorded. For this Sum parameter (CBS) exists for the industry an introduction limit value.
Durch Oxidation der organischen Schadstoffe kann der CSB-Wert gesenkt werden. Dieser Vorgang kann insbesondere elektrochemisch, aber auch durch Chemikalienzugabe oder durch Einleitung von Ozongas erfolgen.By Oxidation of organic pollutants can lower the COD value become. This process can be particularly electrochemical, but also by Chemical addition or by introducing ozone gas.
Beim
elektrochemischen CBS-Abbau erfolgt die Oxidation der organischen
Schadstoffe über OH-Radikale, die an der Anode generiert
werden. Dieses Verfahren wird beispielsweise in den Patentdokumenten
Wie aus dem Stand der Technik ersichtlich ist, hängt die Effizienz des elektrochemischen CSB-Abbaus maßgeblich von der Stromausbeute und von der Zellspannung des Oxidationsvorganges ab. Diese sind wiederum von vielen Faktoren abhängig, beispielsweise der angewandten Stromdichte, dem Elektrodenmaterial, dem Diffusionsweg zur Elektrodenoberfläche und der elektrischen Leitfähigkeit. Natürlich spielt auch der Abwasserinhalt, d. h. die Verunreinigung mit den Abwasserinhaltsstoffen, in besonderer Weise eine Rolle.As From the prior art, the efficiency depends the electrochemical COD degradation significantly from the current efficiency and from the cell voltage of the oxidation process. These are in turn depends on many factors, such as those used Current density, the electrode material, the diffusion path to the electrode surface and the electrical conductivity. Naturally also plays the wastewater content, d. H. the pollution with the Wastewater ingredients, in a special way a role.

und Elektrodenanordnungen bekannt. Diese Reaktoren können sowohl
im Batch-Betrieb, d. h. diskontinuierlich, aber auch kontinuierlich
betrieben werden. Des Weiteren kann dabei mit fester Anode bzw.
Kathode oder aber mit wechselnd polarisierten Elektroden gearbeitet werden.

Mit der Erfindung ist ein Verfahren angegeben, welches die Energieeffizienz des elektrochemischen CSB-Abbaus speziell durch eine vorherige Aufkonzentration des zu behandelnden Flüssigkeitsstromes steigert. Dabei können die an sich bekannten unterschiedlichen methodischen Ansätze verwendet werden. Beispielsweise kann die Aufkonzentration durch Membranprozesse – wie Ultrafiltration (UF), wie Nanofiltration (NF), wie Reverse Osmose (RO), und/oder Elektrodialyse (ED) erfolgen. Insbesondere können derartige unterschiedliche methodische Ansätze miteinander kombiniert werden. Damit lassen sich Verfahren definieren, durch welche die Energieeffizienz einer elektrochemischen Zelle speziell für den CSB-Abbau deutlich steigern lässt. Da der CSB-Abbau durch Oxidation an der Anodenoberfläche geschieht, muss im Rahmen der Erfindung ein effektiver Stoffumsatz gewährleistet sein, so dass sich immer genügend organischer CSB im Bereich der Elektrode befindet. Dies erfolgt erfindungsgemäß durch die vorgeschaltete Aufkonzentration, wobei mit der vorgeschalteten Aufkonzentrationsstufe des zu behandelnden Flüssigkeitsstromes die mittleren Diffusionswege zur Elektrode reduziert werden. Dies bedeutet, dass bei höherer CSB-Konzentration statistisch deutlich mehr organische Moleküle auf die Elektrode treffen und somit ein erheblich gesteigerter CSB-Abbau stattfindet.With The invention specifies a method which improves energy efficiency the electrochemical COD degradation especially by a prior concentration of the liquid stream to be treated increases. there can the different methodical ones known per se Approaches are used. For example, the concentration through membrane processes - such as ultrafiltration (UF), such as nanofiltration (NF), such as reverse osmosis (RO), and / or electrodialysis (ED). In particular, such different methodological Approaches can be combined with each other. This can be done Defining procedures by which the energy efficiency of an electrochemical Cell can be significantly increased especially for the COD degradation. Since the COD degradation by oxidation at the anode surface happens, must within the scope of the invention, an effective material conversion be assured, so that is always enough organic COD is located in the area of the electrode. this happens according to the invention by the upstream concentration, with the upstream concentration level of the to be treated Liquid flow the middle diffusion paths to the electrode be reduced. This means that at higher COD concentration statistically significantly more organic molecules on the electrode meet and thus a significantly increased COD degradation takes place.
Durch die erfindungsgemäße Aufkonzentration steigt in bekannter Weise die Leitfähigkeit des Mediums, wodurch sich die Zellspannung reduziert. Damit kann im erfindungsgemäßen Sinne die Effizienz des Verfahrens weiter gesteigert werden. Außerdem besteht dadurch die Möglichkeit, den Zellaufbau zu optimieren. Beispielsweise vereinfachen größere Elektrodenabstände die Durchmischung und es kann dadurch eine leichtere Reinigung der Anlage erfolgen. Auch damit wird die Effektivität der erfindungsgemäßen Anlage gesteigert.By the concentration according to the invention increases in known manner, the conductivity of the medium, thereby the cell voltage is reduced. This can be in the inventive Meaning the efficiency of the process can be further increased. Furthermore Thereby there is the possibility to optimize the cell structure. For example, simplify larger electrode distances the mixing and it can thus facilitate the cleaning Plant made. Even so, the effectiveness of the invention Plant increased.

Im industriellen Bereich ist die verunreinigte Flüssigkeit meist ein Industriewasser, das insbesondere mit organischen Substanzen belastet ist. Die Summe der Verunreinigungen wird durch den so genannten CSB-Abbau definiert. Für die Praxis existieren klare gesetzliche Vorgaben für den Wert einer zulässigen CSB-Verunreinigung.
