Het potentieel van elektrochemische oxidatie voor de vermindering van anaerobe toxiciteit van 4-chloorfenol bevattend afvalwater

The objective of this research project is the intensification of anaerobic wastewater treatment by the use of electrochemical oxidation. By the use of this electrochemical technique as a pretreatment step or in recycle of an anaerobic reactor, inhibitory components such as monohalogenated aromatics can be electrochemically oxidized in order to assure better biodegradability. As a model compound, 4-chlorophenol is used for the evaluation of the electrochemical oxidation technique. As electrode materials, a titanium cathode was chosen in combination with a titanium anode which is coated with a mixed metal oxide (RuO2-IrO2). This anode material is very stable and commercially available at relatively low cost. In this research, a full characterization of the electrochemical oxidation process as well as the anaerobic wastewater treatment process is made for wastewater containing monohalogenated aromatics. Finally, the combination of these two techniques is evaluated in a continuously operated lab scale set-up.nrpages: 156status: publishe
