    • A structure of a device for automatically controlling a sequence of water treatment to reduce nitrate nitrite ions in water being treated by an electrochemical reaction, to substitute nitrogen gas for the produced ammonia, and thereby to remove the ammonia from the water and a sensing method using such a device for automatically detecting the progress of reduction or denitrification or degradation of the treating capability of the cathode or anode are disclosed. The water treating device comprises a cathode 15 for reducing nitrate nitrite ions by an electrochemical reaction, an anode 16, an electrolytic bath 10 containing the cathode and anode, and a hydrogen gas sensor 30 for measuring the concentration of the hydrogen gas in the electrolytic bath 10. Water to be treated is introduced into the electrolytic bath 10. Current is applied to the water. The end of the reduction of the nitrate nitrite ions or degradation of reduction capability of the cathode 15 can be sensed on the basis of the value measured by the hydrogen gas sensor 30 or the controlled current value of the electrolytic bath 10.

    • A water treating device comprising a water tank for storing untreated water, an electrolytic tank for sterilizing untreated water by a electrochemical decomposition by energizing an electrode set consisting of at least two electrodes, a water treating route for introducing the untreated water to the electrolytic tank from the water tank and refluxing it to the water tank after sterilization in an electrolytic tank, a residual chlorine sensor for measuring the residual chlorine concentration of untreated water prior to introduction into the electrolytic tank, and a control means for controlling the electrochemically decomposed amount of untreated water in the electrolytic tank based on a residual chlorine concentration measured by the residual chlorine sensor to keep the residual chlorine concentration of water refluxed to the water tank within a specified range, characterized in that a branching route is provided that branches from the portion of the water treating route upstream the electrolytic tank to allow untreated water to flow out, conducts the untreated water to the residual chlorine sensor to have it measure untreated water for residual chlorine concentration, and discharges the measured untreated water into the electrolytic tank. Since the above arrangement returns untreated water having the residual chlorine concentration thereof measured in the branching route to the electrolytic tank, water is not wasted. In addition, since untreated water returned to the electrolytic tank is returned the water tank after sterilized in the electrolytic tank, no unsterilized untreated water is returned to the water tank.
    • 一种水处理装置,包括:用于储存未处理水的水箱;电解槽,用于通过对由至少两个电极组成的电极组进行电化学分解而对未处理水进行灭菌;水处理路线,用于将未经处理的水引入到电解槽中 水箱,并在电解槽中灭菌后将其回流至水箱,将残留氯传感器用于在引入电解槽之前测量未处理水的残留氯浓度;以及控制装置,用于控制未经处理的电化学分解量 基于由残留氯传感器测量的残留氯浓度的电解槽中的水,以将水的残余氯浓度保持在规定范围内回流到水箱,其特征在于,提供从所述部分的分支 水处理路线上游e 放置槽以允许未经处理的水流出,将未处理的水导入残留氯传感器,以测量未经处理的水的残留氯浓度,并将测量的未处理的水排放到电解槽中。 由于上述布置使得在分支路线中测量到残留氯浓度的未处理水返回到电解槽,因此不会浪费水。 此外,由于回流到电解槽的未经处理的水在电解槽中灭菌后返回水箱,所以未经灭菌的未经处理的水返回到水箱。
