  • Publication number: 20180065864
    Abstract: The present disclosure provides a liquid treatment method and apparatus according to which poorly treated liquid is prevented from being discharged to the outside thereof. The liquid treatment apparatus of the present disclosure comprises a channel switch, a return channel that establishes communication between the channel switch and an internal space of a first tank, and a discharge channel that establishes communication between the channel switch and the outside of the liquid treatment apparatus. In the circulation state, the liquid mixture is circulated in the liquid treatment apparatus so as to return a liquid to the first tank through the return channel. If a concentration of the photocatalyst particles contained in the first tank falls within a predetermined range, the channel switch is switched from the circulation state to the discharge state to discharge the liquid to the outside of the liquid treatment apparatus.
