Description

technical field [0001] The invention relates to the technical field of sewage treatment. Background technique [0002] Photoelectrochemical technology with external electric field is a new type of deep oxidation technology combined with photocatalysis and electrochemical oxidation. It is also a frontier topic in the field of organic pollutant degradation in wastewater, and has attracted widespread attention in recent years. The relevant research work is mainly focused on proving that the external electric field can significantly enhance the efficiency of the photocatalytic reaction, the so-called electric field enhancement effect. However, there are few research works on high voltage, and even less common research on the reactor. The heterogeneous photocatalytic reactors mainly include annular, oval, multi-lamp and membrane types. At present, the most widely used is a batch-type cylindrical photoreactor, and the reactor with a porous gas distribution plate has a good liquid...
