Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and in particular relates to a silicon carbide / BDD rod-shaped continuous electrode electrolytic cell. Background Art

[0002] As an environmentally friendly treatment technology, the electrochemical advanced oxidation process is one of the most promising methods for treating highly difficult organic wastewater. The BDD thin film electrode is a third-generation electrode with excellent physicochemical stability, adsorption resistance and corrosion resistance. The potential window is as high as 3V, which is higher than the reaction potential of almost all organic matter. The low and stable background current requires a small voltage to produce the same redox current, and the energy consumption is low. When in service, it can produce highly oxidizing hydroxyl radicals (·OH), which can non-selectively oxidize most high-concentration, difficult-to-degrade organic wastewater. The development of an advanced oxidation treatment electrolytic cell device based on large-scale BDD thin film electrodes is the key to whether difficult-to-treat organic wastewater can be degraded efficiently and with low energy consumption.

[0003] Large-scale BDD thin-film electrode advanced oxidation treatment electrolyzers utilize several BDD thin-film electrodes grown on a flat, two-dimensional substrate (such as Si or metallic Nb) and integrated in a specific manner. This allows wastewater to circulate within the sealed electrolyzer, where organic matter is degraded into the end products CO2 and H2O by the strong oxidant ·OH. A problem with conventional flat, two-dimensional Si (or Nb) / BDD electrodes is their limited electrochemically active area, resulting in inefficient organic wastewater degradation.
