[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for decomposing organic substances mainly for improving drinking water.

[0002]

2. Description of the Related Art Tap water contains a large amount of chlorine for sterilization, and there is a concern that well water and river water may contain harmful trihalomethanes in addition to environmental hormones.

[0003] By the way, in order to purify such water, it has conventionally relied heavily on water purifiers, and generally the most well-known water purifiers are of a filtration type such as a hollow filter and a ceramic filter. I have.
In addition, electrolyzers and the like are known for purifying water.

[0004]

However, such a conventional water purification method aims at removing impurities and the like contained in the water, and decomposes organic matter in the water to improve the characteristics of the water itself. It was not intended to remove trihalomethane, environmental hormones, etc., because it was not actively changed.

[0005] The present invention has been made in view of such conventional problems, and has as its object to actively decompose organic substances contained in water to enable fundamental purification of water. is there.
