The present application is further described in detail below in conjunction with Figures 1-3.

The embodiment of the present application discloses a multi-stage series water purification device. Referring to Figure 1, a multi-stage series water purification device includes a valve controller 1 and a coarse filter PP cotton filter element 2, a pre-activated carbon filter element assembly 3, a fine filter PP cotton filter element 4, a reverse osmosis membrane filter element 5, a post-activated carbon filter element assembly 6, and an electro-physical enhanced disinfection device 7 arranged in series.

Through multi-stage filtration, impurities such as soluble solids, organic matter, and inorganic salts in the raw water can be effectively removed, and harmful substances such as bacteria, viruses, and heavy metals in the raw water can be adsorbed and filtered, thereby improving the quality of purified water and drinking taste. In addition, the electrophysical enhanced disinfection device 7 uses a local strong electric field to induce electroporation to sterilize the water body. The specific treatment method is: the electrophysical enhanced disinfection device 7 applies voltage to the electrode modified with a one-dimensional nanostructure, and uses the lightning rod effect generated by the tip of the nanowire to achieve local enhancement of the electric field, thereby achieving irreversible electroporation under low voltage conditions to effectively inactivate pathogens in the water body. As a pure physical process, the electrophysical enhanced disinfection device 7 does not generate chemical disinfectants such as chemical additions and active oxygen free radicals during the disinfection process, thus avoiding secondary pollution of the water body by the addition of chlorine-containing disinfectants and reducing the risk of harm to human health after water disinfection.
