Description

technical field [0001] The invention belongs to the technical field of water pollution control, and in particular relates to a device and method for treating wastewater by electrochemical technology. Background technique [0002] The three-dimensional electrode method has been widely used in the field of wastewater treatment because the particle electrode can effectively increase the specific surface area of ​​the electrode, enhance mass transfer, and then improve the current efficiency and space-time yield. The particle electrode will be polarized during the treatment of wastewater by the three-dimensional electrode method, and the positive and negative electrodes are formed at both ends of the particle, which can be regarded as small electrolytic cells connected in series. The more effective cells, the higher the current efficiency, the higher the reaction efficiency, and the lower the energy consumption. lower. However, the current efficiency of the three-dimensional ele...
