“…), the direct oxidation of the organic compounds at the anode surface also takes place . Some compounds can be degraded more easily by the combination of oxidation and reduction than by pure oxidation and an undivided electrochemical system or sequential process control is chosen for the alternating degradation mechanism . An often studied and commercially available E‐AOP systems on a small scale are based on boron‐doped diamond electrodes (BDD) , on the anode and cathode sides, whereby other anode materials are also possible (Tab.…”

Regarding the treatment of (waste)water, electrochemical processes have various advantages over other methods. They are robust, easy to operate and flexible in case of fluctuating wastewater streams. In addition, a relatively broad spectrum of organic and inorganic impurities can be removed. This contribution provides an overview of electrochemical reactors for water, process water, and wastewater treatment, which are already in technical‐scale operation or subject of research. Some essential basics of electrochemical processes for the treatment of water are presented and examples for applications are given. This is followed by a description of the reactors.

Bei der Aufbereitung von (Ab-)Wasser haben elektrochemische Verfahren verschiedene Vorteile gegenüber anderen Aufbereitungsmethoden. Sie sind robust, einfach in der Betriebsführung und flexibel bei Schwankungen der Abwasserfracht. Zudem kann ein relativ breites Spektrum an organischen und anorganischen Verunreinigungen entfernt werden. Dieser Beitrag gibt eine Ü bersicht zu den elektrochemischen Reaktoren, die in der Aufbereitung von Wasser, Prozesswasser und Abwasser bereits eingesetzt oder beforscht werden. Es werden zunächst einige wesentliche Grundlagen der elektrochemischen Verfahren zur Behandlung von Wasser vorgestellt und Beispiele für Anwendungen gegeben. Daran schließt sich die Beschreibung der verwendeten Reaktoren an.

“…Advanced oxidation processes (AOPs) based on reactive oxidizing radicals are widely used in the treatment of organic wastewater due to the high degradation efficiencies of organic pollutants and their environmentally friendly nature [4,5]. The performance of AOPs for the degradation of refractory organic pollutants has been evaluated by Fenton and Fenton-like processes [6], ozonation [7], photocatalysis [8], photo-Fenton [9], and electrochemical oxidation [10].…”

Heterogeneous photo–Fenton reactions have been regarded as important technologies for the treatment of textile dyeing wastewaters. In this work, an efficient core-shell magnetic anion exchange resin (MAER) was prepared through in situ polymerization and used to remove reactive brilliant red (X-3B) in a UV–Fenton system. The MAER exhibited satisfactory removal efficiency for X-3B because of its highly effective catalytic activity. More than 99% of the X-3B (50 mg/L) was removed within 20 min in the UV–Fenton reaction. This is because the uniformly dispersed core-shell magnetic microsphere resin could suppress the aggregation of Fe3O4 nanoparticles and, thus, enhance the exposure of Fe reaction sites for catalytic reaction with H2O2. The good adsorption capacity of MAER also played an important role in promoting contact between X-3B and reactive radicals during the reaction. Mechanism research showed that hydroxyl radical (•OH) was the main reactive radicals for the removal of X-3B in the MAER UV–Fenton system. The MAER can be easily separated by a magnet after catalytic reactions. Moreover, the matrix effects of different substrates (Cl−, NO3−, SO42−, and humic acid) were investigated. The results showed that SO42− could be beneficial to improve the removal of X-3B but that the others decrease the removal. The MAER UV–Fenton also removed significant amounts of total organic carbon (TOC) for the X-3B solution and an actual textile dyeing industrial wastewater. The heterogeneous oxidation system established in this work may suggest prospects for practical applications in the treatment of textile dyeing wastewater.
