NOVELTY - The utility model claims a three-dimensional electrochemical sterilizing device with synergistic effect, comprising a purifying cavity with a water inlet pipe and a water outlet pipe, a first electrode and a second electrode oppositely set in the purifying cavity, a power supply device electrically connected with the first electrode and the second electrode; the purifying cavity is further filled with micro-ball of sheet-shaped nano graphene material; the first electrode and the second electrode; the micro-sphere sheet-shaped nano graphene material forms a three-dimensional electrode system. The utility model claims a boron-doped diamond film electrode-metal electrode-graphene three-dimensional electrochemical sterilizing device, compared with the two-dimensional electrochemical system, the sterilizing efficiency is improved by 100 %, and it can continuously sterilize for a period of time after power-off. The sterilizing device has simple structure, high sterilizing efficiency, improves the cost benefit of electrochemical sterilizing, and it has important application value for the application and popularization of electrochemical sterilizing.
