摘要:
In a water treatment apparatus, the time for treatment after water to be treated is introduced into an electrolytic bath is reduced. The water to be treated in a reservoir is subjected to electrolysis at a first electrolytic bath. Electrolysis is carried out at respective first and second electrolytic baths. By the electrolysis at the second electrolytic bath, hypochlorous acid is generated from chloride ions at the anode side. The solution subjected to electrolysis at the second electrolytic bath is mixed at a predetermined site of the pipe connected between the reservoir and the first electrolytic bath with the water output from the reservoir via a pipe prior to introduction into the first electrolytic bath. Accordingly, the water subjected to electrolysis at the first electrolytic bath can be sterilized in advance by the hypochlorous acid generated by electrolysis at the second electrolytic bath.

A waste treatment system permitting treatment of organic wastes at low cost is provided. In the waste treatment system, organic wastes such as sewage, garbage and sludge are introduced into a methane fermentation bath for anaerobic fermentation. The methane gas produced in the bath is refined in a gas holder and then supplied to an electric generator, where the methane gas is used as a raw material for power generation. Digested liquid within the methane fermentation bath is supplied to an electrolytic bath via a flow adjustment bath and a fine screen. In the electrolytic bath, the digested liquid is subjected to electrolysis, by applying potentials to an electrode pair in the electrolytic bath based on the electric power obtained by the electric generator. By the electrolysis, nitrogen components including organic nitrogen and ammonia nitrogen, and BOD, SS and phosphorus components are removed from the digested liquid.

A water treatment apparatus includes a storage unit storing water to be treated including a pharmaceutical drug, an apply unit applying the water to be treated to the storage unit, an addition unit adding into the water to be treated metal salt generating halide ions when dissolved in the water to be treated, and an energizing unit applying a current to a pair of electrodes immersed in the water to be treated in the storage unit. The pharmacological activity of the pharmaceutical drug is eliminated or reduced by decomposing or altering at least a portion of the chemical structure of the pharmaceutical drug included in the water to be treated through electrolysis.

A water treating device includes a water container for containing water; an electrolyzing chamber for sterilizing water; a water treatment line which couples the electrolyzing chamber with the water container; a sensor for measuring residual chlorine concentration; and a device for controlling the amount of the water to be electrochemically decomposed in the electrolyzing chamber on the basis of the residual chlorine concentration measured by the sensor to keep the residual chlorine concentration of the water to be fed back into the water container within a predetermined range. A bypass line is provided which is branched from the water treatment line upstream of the electrolyzing chamber for sampling the water, introducing the sampled water into the sensor for the measurement of the residual chlorine concentration thereof, and discharging the sampled water into the electrolyzing chamber after the measurement.
