Liquid treatment apparatus and liquid treatment method

摘要

A liquid treatment apparatus according to the present disclosure includes a dielectric tube that defines a channel through which water to be treated flows, the channel being split upstream of the dielectric tube into a first channel and a second channel, the first channel and the second channel being merged with each other downstream of the dielectric tube, a first electrode at least partially disposed within the first channel, a second electrode at least partially disposed within the first channel, a first gas-supply unit that supplies gas to form a gas bubble into water to be treated that flows through the first channel, and a first power-supply that applies a voltage between the first electrode and the second electrode.

1. A liquid treatment apparatus comprising:
a dielectric tube, having an inlet and an outlet for water to be treated, for defining a channel through which the water to be treated flows from the inlet to the outlet, the channel being split into at least a first channel and a second channel at an inlet side of the dielectric tube, the first channel and the second channel being merged with each other at an outlet side of the dielectric tube;
a first electrode at least partially disposed within the first channel;a second electrode at least partially disposed within the first channel, the second electrode being disposed on an inlet side of the first channel relative to the first electrode; a first gas-supply unit that supplies gas to form a gas bubble into the water to be treated to cause the gas bubble to cover at least part of the first electrode and flow through the first channel to the outlet; and a first power-supply that applies a voltage between the first electrode and the second electrode, wherein no gas bubble is in direct contact with the second electrode.
