Abstract: A liquid processing apparatus includes a processing tank, a first electrode, an insulator, a liquid introduction port, a discharge portion, a second electrode, an opening portion, and a power supply. The first electrode is disposed at the first end of the processing tank. The insulator covers at least a part of a side surface of the first electrode disposed to protrude from an inner wall of the first end of the processing tank into the processing tank. The liquid introduction port causes a liquid to swirl by introducing the liquid in a tangential direction of the processing tank and generates a gas phase in a swirling flow of the liquid. An outer diameter of the insulator is smaller than an outer diameter of a gas-phase generating space where the gas phase is generated in the processing tank.

Abstract: A liquid treatment device that achieves an effective treatment by forcibly contacting a swirl flow of a hydrogen peroxide-containing treated liquid with a liquid to be treated that has been processed to contain copper ions or iron ions includes a rod-like first electrode, a plate-like second electrode formed of a copper- or iron-containing metal, and a first treatment vessel that causes a liquid to swirl and generate a gas phase in a swirl flow of the liquid. A pulse voltage is applied to the generated gas phase to generate a plasma. The second electrode serves as an anode, and reaches inside of a supply section for a liquid to be treated. The liquid to be treated containing the generated copper ions or iron ions is forcibly brought into contact with hydrogen peroxide generated by the plasma. In this way, the Fenton's reaction effectively takes place, and the liquid treatment performance improves.

Abstract: A liquid treatment device that can improve liquid treatment performance by taking advantage of the Fenton's reaction while efficiently generating plasma for liquid treatment, in addition to enabling stable plasma generation for extended time periods includes a first electrode that is rod-like in shape; a second electrode that is plate-like in shape and is 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.
