Abstract
In a water treatment apparatus, a tilted plate is disposed at an incline relative to a horizontal plane. Water to be treated is passed over the upper surface of the tilted plate. A discharge forming body is disposed across a gas layer above a water film formed by the water to be treated flowing over the tilted plate. A droplet forming apparatus exerts power on the water film so that at least some of the water to be treated shoots upward in the form of droplets.
Claims11
A water treatment apparatus comprising:
- a tilted plate disposed at an incline relative to a horizontal plane so that water to be treated flows over an upper surface thereof, wherein a narrow hole is provided in the tilted plate so as to penetrate the tilted plate in a thickness direction;
- a discharge forming body that is disposed across a gas layer above a water film formed by the water to be treated flowing over the tilted plate, and forms a discharge by applying a voltage between the discharge forming body and the tilted plate, and
- a droplet forming apparatus configured to perform an operation for exerting power on the water film so that droplets shoot up from the water film, wherein the droplet forming apparatus is a gas ejection apparatus that forms droplets by ejecting gas upward through the narrow hole so that the water to be treated splashes up to shoot upward and form droplets,
- wherein treatment is performed on the water to be treated by bringing the droplets, which are formed by the power exerted by the droplet forming apparatus, into contact with the discharge.

A water treatment method for treating water to be treated comprising:
- passing the water to be treated over an upper surface of a tilted plate disposed at an incline relative to a horizontal plane so that a water film is formed on the tilted plate, wherein a narrow hole is provided in the tilted plate so as to penetrate the tilted plate in a thickness direction;
- forming, via a discharge forming body that is disposed across a gas layer above the water film, a discharge by applying a voltage between the discharge forming body and the tilted plate;
- performing, via a droplet forming apparatus, an operation for exerting power on the water film so that droplets shoot up from the water film, wherein the droplet forming apparatus is a gas ejection apparatus that forms droplets by ejecting gas upward through the narrow hole so that the water to be treated splashes up to shoot upward and form droplets;
- and
- performing treatment on the water to be treated by bringing the droplets formed by the power exerted by the droplet forming apparatus into contact with the discharge.
