Embodiment 1

[0016] Embodiment 1. This embodiment provides an electro-adsorption module modification system. It is found through research that the functional groups generated due to oxidation can be eliminated by electrochemical reduction, thereby restoring the adsorption performance of the electrode material. Therefore, in this embodiment, the third electrode is introduced to electrochemically reduce the oxidized electrodes, and a stronger oxidation potential is applied to the third electrode, so that the electrode performance can be restored without destroying the electrodes used for adsorption in the module. see Picture 1-1 and Figure 1-2 shown, including:

[0017] The first electrode 11 and the second electrode 12 form the electrosorption module 1 when the electrosorption works.

[0018] The third electrode 21 does not participate in the normal adsorption process of the first electrode 11 and the second electrode 12, and only participates when the first electrode 11 and the second e...

Embodiment 2

[0020] Embodiment 2. This embodiment provides an electro-adsorption module modification process, which is implemented using the system described in Embodiment 1. In this embodiment, it is assumed that the first electrode is used as the electrosorption anode during the electrosorption process. Specifically, in the electrochemical modification process, the third electrode is used as a modified anode, and the first electrode is used as a modified cathode. The reduction potential applied between the third electrode and the first electrode is greater than the potential applied during the electrosorption of the electrosorption module, and then cathodically polarizes the first electrode as the modified cathode to complete the modification of the first electrode . The inventor considers that if the cathode has sufficient reduction potential, it will inevitably cause stronger damage to the third electrode as the anode, so a porous water-permeable inert electrode material can be used t...

Embodiment 3

[0021] Embodiment 3. This embodiment provides an electro-adsorption module modification process, which is implemented using the system described in Embodiment 1. In this embodiment, the electro-adsorption working process adopts the pole-reverse operation mode.

[0022] It has been found through research that the functional groups generated due to oxidation can be eliminated by electrochemical reduction, thereby restoring the adsorption performance of the electrode material. The basic unit of the electro-adsorption module is composed of positive and negative electrodes, and when the adsorption unit is formed, the potential is always positive, and the oxidation effect is much stronger than the reduction effect, that is, when the two electrodes are used as anodes, oxidation reactions will occur. However, when it is used as the cathode, there is not enough reduction potential to reduce it. If the cathode has sufficient reduction potential, it will inevitably cause stronger damage t...

Abstract

The invention discloses an electro-adsorption module modification system and a process, which relate to the field of water treatment, and aim to solve the problem that the desalting efficiency of the electro-adsorption module is affected due to accumulation of surface side reaction effects in a long-time running process of an existing electro-adsorption system. The system comprises a first electrode, a second electrode, a third electrode and a modification unit, wherein the first electrode and the second electrode form the electro-adsorption module when electro-adsorption is carried out; the third electrode is used as a positive electrode when the electro-adsorption module is modified; and the modification unit is formed by the third electrode used as the modified positive electrode, and the first electrode or the second electrode used as the positive electrode during electro-adsorption work while as a negative electrode during modification, and is used for carrying out cathodic polarization on the modified negative electrode so as to complete modification of the electro-adsorption module. The process comprises the following steps of: adopting the third electrode as the modified positive electrode, andthe first electrode or the second electrode as the modified negative electrode; and carrying out cathodic polarization on the first electrode or the second electrode used as the modified negative electrode so as to complete modification of the electro-adsorption module; and the steps are implemented by adopting the system.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an electro-adsorption module modification system and process. Background technique [0002] As a water treatment technology, the electro-adsorption desalination technology, its core equipment is the electro-adsorption module, and its overall technological process is divided into two parts, the working process and the regeneration process. The working process is to connect the opposite electrode sheets in the electro-adsorption module with positive and negative charges, and use the potential difference between the electrode sheets to adsorb anions and cations in the raw water to achieve the process of purifying the raw water. There are two effects in the working process, capacitive adsorption and surface side reaction. Capacitive adsorption is a desalination process in which positive and negative ions in water are enriched on the electrode surface, while surface side reaction is a s...
