    • 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).
    • 提供一种能够通过电化学反应处理的水中的硝酸盐(亚硝酸盐)离子的自动控制进行水处理顺序的处理的装置结构,并且用氮气取代得到的氨从水中除去氨; 以及使用该装置自动检测还原或反硝化进程或降低阴极或阳极处理能力的检测方法。 水处理装置包括通过电化学反应减少硝酸盐(亚硝酸盐)离子的阴极(15),阳极(16),含有阴极和阳极的电解浴(10)和氢气传感器(30),其中 测量电解槽(10)中的氢气浓度。 将待处理的水引入电解槽(10)中,向水施加电流。 可以基于由氢气传感器(30)测量的值或者控制电流值来检测硝酸盐(亚硝酸盐)离子的还原的完成或阴极(15)的还原能力的降低 电解槽(10)。
