In addition, the electrode plate 5 may be attached above the conductive separator 2 by conductive glue, and the electrode plate 5 may be a thin skin of 100 × 20 × 1 mm.
The controller 3 is communicatively connected to a power source 6. The controller 3 is used for controlling the power supply process of the power supply 6 to the conductive partition plate 2 to realize the desalting operation of the wastewater. The principle of the electro-adsorption technology is that an electrostatic field is formed between electrodes through an external voltage, charged ions are forced to move to an electrode plate 5 with opposite polarity to the charge of the ions under the action of static electricity in the electrostatic field, an electric double layer is formed on the surface of the electrode plate 5, the charged ions are adsorbed and temporarily stored in the electric double layer, and then charged salt ions are adsorbed on the electrode plate 5 through the applied voltage, so that the desalination of wastewater is realized. Based on this electrosorption principle, controller 3 controls power 6 earlier and supplies power to conductive partition plate 2 in this embodiment, and then utilizes the condenser that two arbitrary conductive partition plates 2 formed to carry out the absorption of salt ion in the waste water, realizes the desalination process of waste water. After the desalination is finished, the controller 3 controls the power supply 6 to stop supplying power.
In order to determine whether the salt ions in the wastewater have been removed, i.e. whether the desalination process of the wastewater in the desalination apparatus is finished, the desalination apparatus provided in this embodiment further comprises a second conductivity detection unit 9. The second conductivity detection unit 9 is disposed in the insulating housing 1 and is in contact with the wastewater in the insulating housing 1. The second conductivity detection unit 9 is in communication with the controller 3. The second conductivity detection unit 9 is used for detecting the second conductivity of the wastewater in the insulating housing 1 in real time and transmitting the second conductivity to the controller 3. The controller 3 is used for controlling the power supply 6 to stop supplying power after the value of the second conductivity is maintained for a preset time, and further judging whether the desalting process of the wastewater in the desalting device is finished or not by detecting the conductivity of the wastewater. Of course, it will be understood by those skilled in the art that any other manner capable of determining the completion of the wastewater desalination process is within the scope of the present embodiment.
In order to further improve the desalination efficiency of the desalination apparatus, the present embodiment further sets a power supply voltage for supplying the power source 6 to the conductive separator 2. In order to realize that the power supply 6 supplies power to the conductive separator 2 at an optimum voltage, the desalination apparatus of the present embodiment further includes a salt concentration detection unit 10. The salt concentration detection unit 10 is disposed in the water storage device 7, and the salt concentration detection unit 10 is in communication connection with the controller 3. The salt concentration detection unit 10 is used for detecting the salt concentration of the wastewater in the water storage device 7 and transmitting the salt concentration to the controller 3. The controller 3 is used for adjusting the output voltage of the power supply 6 according to the salt concentration, and the output voltage of the power supply 6 is the same as the preset optimal voltage corresponding to the salt concentration. That is, in this embodiment, a simulation experiment is performed on wastewater containing different salt concentrations in advance to determine optimal voltages corresponding to wastewater containing different salt concentrations, and then preset optimal voltages corresponding to different salt concentrations are obtained. When the desalination operation is actually carried out on the wastewater, the salt concentration of the wastewater is detected firstly, then the optimal voltage of the power supply 6 is determined according to the salt concentration, and the power supply 6 is controlled to output the optimal voltage through the controller 3, so that the desalination efficiency of the desalination device is obviously improved.
In order to realize the recycling of the electrode plate 5, the desalination device of the embodiment further comprises a short-circuit lead 11 and a short-circuit lead switch 12. The short circuit leads 11 are electrically connected with the electrode plates 5 in a one-to-one correspondence manner, a short circuit lead switch 12 is arranged between two short circuit leads 11 correspondingly connected with two adjacent electrode plates 5 which are randomly arranged on different conductive partition plates 2, and the short circuit lead switch 12 is electrically connected with the short circuit leads 11.

And then after electrode plate 5 adsorbs saturation, the desalination device gets into regeneration operating condition, and controller 3 control short circuit wire switch 12 is closed, and power 6 disconnection this moment, power 6 do not supply power to electrically conductive partition plate 2 promptly, and then two adjacent electrode plate 5 short circuits, and the voltage disappears gradually, and the adsorption effect will disappear, and the ion of adsorbing in the electrode plate 5 will be merged into in the fluid between two electrically conductive partition plate 2 to guarantee the used repeatedly of electrode plate 5. In addition, in the present embodiment, only the power supply 6 needs to be disconnected, and the regeneration of the electrode plate 5 can be realized without any operation, and the present embodiment may also be reversely connected to the power supply 6, that is, the conductive partition 2 previously connected to the positive electrode of the power supply 6 is connected to the negative electrode of the power supply 6, and the conductive partition 2 previously connected to the negative electrode of the power supply 6 is connected to the positive electrode of the power supply 6, so as to realize the regeneration of the electrode plate 5. The three regeneration methods have respective lower regeneration efficiencies than those of the method of reversely connecting the power supply 6, the method of short-circuiting the two electrode plates 5, and the method of disconnecting only the power supply 6. When the electrode plate 5 is judged to be saturated, the method used in this embodiment is to introduce the wastewater into the insulating housing 1, and switch on the power supply 6 for adsorption, so that the desalination device works in an adsorption state. If the first conductivity and the second conductivity are always the same, it represents that the electrode plate 5 is saturated by adsorption, and at this time, the regeneration of the electrode plate 5 should be performed to operate the desalination device in a regeneration state. When the electrode plate 5 is regenerated, the fluid introduced into the insulating case 1 may be waste water, or may be any other water quality or any kind of water.
In addition, none of the conventional electro-adsorption desalination devices can select the type of ions adsorbed by the electrode plates 5, and in order to achieve selective adsorption of ions, the desalination device of the present embodiment is provided with a selectively permeable membrane on each electrode plate 5.
