The present invention relates to a desalination apparatus for desalination by removing organic substances contained in contaminated water, and in particular, by attaching carbon fibers to electrode cells of the desalination apparatus to remove organic substances as well as removing saturated ions stuck to the electrode cells. It relates to a desalination treatment and deionization device of the desalination device.

In general, the desalination apparatus is a device for desalination by removing various suspended substances or ions contained in contaminated water such as seawater or wastewater, and the desalination apparatus is an evaporation which evaporates water by using a heat source such as fossil fuel or electricity. A method, a filtration method for filtering out foreign substances using a separation membrane, and an electrodialysis method for removing ions using an electrolysis of an electrode cell have been proposed.

However, since the evaporation method is a state in which water is evaporated by using fossil fuel or electricity as a heat source, the volume of the denitrification device becomes large, which is not only spatially inefficient, but also increases energy consumption and increases manufacturing cost. There was a problem that causes air pollution due to the use of fuel.

In addition, the filtration method has a problem in that the cost of energy is increased because the foreign material is removed by applying a high pressure to the separator, and the electrodialysis method continuously replaces the electrode cell, thus causing a wasteful factor due to the replacement of the electrode cell. There was a problem that the human and physical incidental costs increase due to the replacement of the cell.

Thus, the present invention was invented to solve the problems described above, by attaching carbon fiber to the electrode cell of the desalination apparatus to remove the organic material as well as to remove the positive anion pressed on the electrode cell as necessary. It is an object of the present invention to provide a desalination and ion removal device for a desalination device.
