PROBLEM TO BE SOLVED: To provide a wastewater treatment apparatus capable of enhancing treatment efficiency and also reducing the cost for the wastewater treatment. SOLUTION: A porous material TiC/Ir obtained via a combustion/synthesis reaction is adopted as a material for electrodes 2, 3 for decomposing the wastewater 11. Because the porous material includes continuous pores which open outside at the surface, the wastewater can be supplied into an electrolysis chamber 1 through the continuous pores of one of the porous material electrodes and the decomposed wastewater 12 can be discharged outside through those of the other of the porous material electrodes. The electrodes made of the porous material can secure a large area of contact between the supplied wastewater and the electrode due to the large surface area thereof and can have the high efficiency for treating the wastewater because of the capability to adsorb and concentrate an organic chemical substance in the wastewater. Therefore, the apparatus requires neither increasing the number of the electrodes to promote the decomposition, nor adding any additives to enhance the electric conductivity of the wastewater, thus reducing the cost for the wastewater treatment.
