Patent ID: 6896790

Claim:
An apparatus for oxidatively destructing a trace injurious substance, comprising: a plurality of anodes, each of said anodes having a surface with an electrically conductive oxide integrally applied thereto and being made of a metal; a partition made of a porous ceramic or resin material and arranged between said anodes; a plurality of cathodes surrounding said anodes, each of said cathodes being made of a metal plate having inner walls on each side to which a noble metal is fused, wherein said anodes, cathodes, and partition are arranged to form at least two chambers in a planar symmetrical arrangement for oxidatively destructing the trace injurious substance contained in polluted water flowing through said chambers; and a rectangular wave discharging device for applying an electric field to said chambers so that the polluted water flowing through a first one of said chambers is subjected to irradiation of the electric field, and so that a resulting supernatant from said first one of said chambers thereafter flows through a second one of said chambers and is subjected to irradiation of the electric field.
