Abstract: The disclosure provides a method and device for preparing slightly acidic electrolyzed water with a controllable and stable concentration. According to the method, a solution addition velocity of a first solution addition device is adjusted according to a difference between a detected voltage Udetected and a control voltage Ucontrol in an electrolytic cell, so that the first solution addition device adds an electrolyte stock solution to the electrolytic cell in real time, thereby preparing the slightly acidic electrolyzed water with a controllable and stable concentration. The device includes an electrolyte stock solution storage, an electrolytic cell and a first mixer connected sequentially. A first solution addition device is connected in series between the electrolyte stock solution storage and the electrolytic cell. The disclosure overcomes the defects of uncontrollable and unstable concentration in the preparation of present slightly acidic electrolyzed water.

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.
