Method for treating coking/semi-coke wastewater by novel electro-adsorption technology

The invention discloses a method for treating coking/semi-coke wastewater by a novel electro-adsorption technology. Low metamorphic bituminous coal (long flame coal, weakly caking coal or non-caking coal) is utilized as a main raw material to prepare a coal-based porous electrode material to serve as a negative pole and a positive pole; activated carbon or active coke is utilized as a particle electrode; under a three-dimensional system, adsorption and electrocatalytic oxidation of the coal-based electrode and the activated carbon under the action of certain electric field pressure are utilized to treat pollutants in the coking/semi-coke wastewater. According to the method disclosed by the invention, the low metamorphic bituminous coal which has rich resource reserve in China is utilized as the raw material to prepare the coal-based electro-adsorption material, and the coal-based electro-adsorption material is applied to conventional treatment of the coking/semi-coke wastewater; thus,treating cost is low, eco
