Electrolytic module units and water treatment systems based on boron-doped diamond (BDD) electrodes

An electrolytic module unit based on a boron-doped diamond (BDD) electrode, comprising a water flow guide module and an electrolytic module, wherein

• the electrolytic module is provided within the water flow guide module;
• the electrolytic module includes a BDD electrode, the BDD electrode includes a main body portion and a plurality of branch portions disposed on two sides of the main body portion, and the main body portion and the plurality of the branch portions on the two sides of the main body portion constitute a fishbone-like structure;
• the water flow guide module includes a main inlet guide tube, a cavity, and a plurality of sub-inlet guide tubes, wherein the cavity is communicated with the main inlet guide tube and two sides of the cavity are perpendicular to the main inlet guide tube;
• the plurality of the sub-inlet guide tubes are communicated with the cavity and the main inlet guide tube, and an communicated end of the each of the plurality of the sub-inlet guide tube communicated with the cavity is perpendicular to an upper surface or a lower surface of the cavity;
• and
• the electrolytic module is arranged in the cavity and parallel to the upper surface and the lower surface of the cavity, and an end portion of the BDD electrode of the fishbone-like structure is far away from the main inlet guide tube.
