APPARATUS FOR OXIDATIVELY DESTRUCTING TRACE INJURIOUS SUBSTANCE

摘要

An oxidatively destructing apparatus comprises anodes each integrally provided with a conductive oxide on its surface and made of a metal, cathodes of a metal plate to which a noble metal is fused, a first chamber (1) housing the anode (1A) and the cathode (1B), a second chamber (2) housing the anode (2A) and the cathode (2B), a partition (20) made of a porous ceramic or resin between the anodes (1A, 2A), and a rectangular wave discharging device for applying an electric field to the first and second chambers. Polluted water fed by a pump (P1) is made to flow through the first chamber (1) and subjected to the electric field. The supernatant in a settling tank (3) is made to flow through the second chamber (2) by a pump (P2) and subjected to the electric field. As a result, soluble COD, ammonia nitrogen, and nitrate nitrogen are efficiently oxidatively destructed.
