摘要:
To provide an apparatus construction which makes it possible to perform a water treatment sequence by automatic control for reducing nitrate (nitrite) ions in water being treated through an electrochemical reaction and substituting nitrogen gas for the resulting ammonia for removal of ammonia from the water; and a detecting method using the apparatus for automatically detecting the progress of reduction or denitrification, or degradation of the treating capability of cathode or anode. The water treatment apparatus comprises a cathode (15) which reduces nitrate (nitrite) ions through an electrochemical reaction, an anode (16), an electrolytic bath (10) containing the cathode and the anode, and a hydrogen gas sensor (30) which measures a hydrogen gas concentration in the electrolytic bath (10). Water to be treated is introduced into the electrolytic bath (10), and an electric current is applied to the water. The completion of the reduction of the nitrate (nitrite) ions or the degradation of reduction capability of the cathode (15) can be detected on the basis of a value measured by the hydrogen gas sensor (30) or a control electric current value of the electrolytic bath (10).
