Abstract
A liquid treatment device includes a rod-shaped first electrode; a plate-shaped second electrode configured from a metal containing copper or iron; and a treatment vessel in which introduced liquid swirls, and generates a gas phase in a swirl flow of the liquid. A plasma is generated by applying a pulse voltage to the generated gas phase, and a negative DC voltage is applied between the first electrode and the second electrode serving as a cathode and an anode, respectively. Under the applied negative voltage, the plate-like second electrode generates copper ions or iron ions, and the copper or iron ions undergo Fenton's reaction with the hydrogen peroxide generated by the plasma so that liquid can be efficiently treated.
