発明の名称 (英語) FIXED-BED ELECTROLYSIS TREATMENT DEVICE AND ELECTROLYSIS TREATMENT METHOD UPDATE
発明の概要(英語) Provided is a fixed-bed electrolysis treatment device for electrochemically treating water to be treated, wherein the fixed-bed electrolysis treatment device is equipped with a fixed-bed electrode having a packed layer of conductive diamond particles; a counter electrode; and an electrolytic cell in which the fixed-bed electrode and the counter electrode are disposed and the water to be treated is passed through or housed. Also provided is an electrolysis treatment method that uses the fixed-bed electrolysis treatment device.
従来技術、競合技術の概要(英語) BACKGROUND ART
Electrically conductive diamond electrodes have a wider potential window than platinum electrodes and the like, can efficiently generate active species such as OH radicals and ozone, and have excellent corrosion resistance. therefore, applications as electrolytic electrodes when electrolytically treating water to be treated such as industrial waste water, for example, are expected.
The conductive diamond is generally formed on a substrate such as a silicon wafer by chemical vapor deposition (CVD). Thus, there is a problem in that the shape of the electrode is limited to a thin film shape. Also, the area of the obtained electrically conductive diamond thin film depends on the size of the CVD device, so there is a problem in that it is difficult to increase the electrode surface area.
In order to solve these problems, application of electrically conductive diamond particles to electrodes has been proposed in recent years. With such electrically conductive diamond particles, the shape of the electrode is not limited to a thin film shape, and in addition, the electrode surface area can be easily enlarged.
For example, Patent Document 1 discloses a fluidized bed electrolytic treatment apparatus using electrically conductive diamond particles as a fluidized bed electrode.
