摘要： Provided is a water treatment system in which the ratio of removal of ions of a scale component can be increased. A water treatment system is equipped with: a pair of electrodes (11, 13) which face each other and can be electrically charged so as to have opposite polarities to each other; an interelectrode flow path (15) which is arranged between the electrodes (11, 13) and through which water containing ions can flow; and ion exchange membranes (12, 14) each of which is arranged on the interelectrode flow patch (15) side of each of the electrode (11, 13) and enables the ions to flow to the electrode (11, 13) side. The water treatment system is also equipped with a desalination unit (10) in which a desalination treatment for adsorbing the ions onto each of the electrodes (11, 13) to desalinate the water and a regeneration treatment for desorbing the ions from each of the electrodes (11, 13) are carried out. One (14) of the ion exchange membranes enables bivalent cations, which are contained in the water containing the ions, to selectively flow to the electrode (13) side.

In this water treatment system (1) and water treatment method, a scale inhibitor is supplied to water to be treated including Ca ions, SO 4 ions, carbonate ions, and silica, and the water to be treated is adjusted to a pH capable of dissolving silica. Having had a calcium-scale inhibitor added thereto and the pH thereof adjusted, the water to be treated is separated by a desalination unit (10) into treated water, and concentrated water in which the Ca ions, SO 4 ions, carbonate ions, and silica are concentrated. In a crystallization unit (20), gypsum seed crystals are supplied to the concentrated water, and gypsum crystallizes and is removed from the concentrated water. The silica in the water to be treated is removed from the concentrated water at a downstream side of the crystallization unit (20) with respect to the water to be treated. Calcium carbonate in the water to be treated is removed from the concentrated water at an up-stream side of the desalination unit (10), or at a downstream side of the crystallization unit (20).

摘要： A water treatment system of the present invention for effluent generated in a plant facility includes: a flue gas treatment system 18 that performs treatment of boiler flue gas 12 from a boiler 11; and a spray drying device 23 that includes a spraying unit, which sprays effluent 22 generated, for example, in a cooler 21 of the plant facility, and that performs spray drying using part 12a of the boiler flue gas 12. The water treatment system draws the effluent 22 is discharged into the spray drying device 23 so as to dry the sprayed liquid by the part 12a of the flue gas 12. It is thus not necessary to separately perform treatment of the effluent 22 in an industrial effluent treatment facility and it is possible to eliminate the need of draining the effluent 22 generated in the plant.

摘要： A water treatment system (1) includes a deionization unit (10) and an ion-selective removing unit (20). The deionization unit (10) includes a pair of opposing electrodes that is charged to have polarities opposite to each other, a flow passageway positioned between the electrodes and enabling passage of water containing ions, and an ion-exchange membrane that is disposed on the flow passageway side of each of the electrodes, and performs a deionization process of deionizing the water containing the ions by allowing the ions to be adsorbed onto the electrodes and a regeneration process of eliminating the ions from the electrodes. The ion-selective removing unit (20) is disposed on the downstream side or upstream side of the deionization unit (10) to separate and remove divalent or more ions from the water containing the ions because the ratio of removing the divalent or more ions that are the scale component among the ions is relatively higher than the ratio of removing monovalent ions from the water containing the ions. The water treatment system (1) can increase the ratio of removing scale component ions.
