Abstract: The advantages and disadvantages of four kinds of carbon electrode materials are introduced.The application cases of electro-absorption desalination technology in coal-fired power plants worldwide are analyzed.Combined with the characteristics of the desulfurization wastewater in power plant, the development direction and some problems of electro-adsorption desalination technology are proposed.Practical applications illustrate that electro-adsorption desalination technology requires simple to pretreatment of wastewater.Two cases of industrial scale applications with a processing capacity of 200 cubic meters per hour or more show that the removal rates of hardness, calcium hardness and chlorides can reach 65%-80% when electro-adsorption desalination technology is applied to treat with the circulating cooling water drainage in coal-fired power plants and the water production rate is 70%-76%.The cost of desalination is low.
