Abstract

The present invention relates to an electrochemical advanced oxidation process combined with a membrane in which electrode reactions and membrane filtration occur simultaneously, a water treatment device based on the electrochemical advanced oxidation process, and a water treatment system using the water treatment device. The electrochemical advanced oxidation process includes: providing a membrane electro-oxidation tank where electrodes are combined with a membrane; accommodating wastewater containing pollutants in the membrane electro-oxidation tank; and supplying power to the electrodes to decompose the pollutants and simultaneously separating particles through the membrane (water treatment). The electrodes are arranged downstream of the membrane. Gases released from the electrodes induce a vertical flow of the fluid to improve the contact efficiency between a reactive solution and the electrodes and remove the pollutants attached to the surface of the membrane. According to the present invention, a mechanism of decomposing pollutants using the electrodes and a mechanism of separating particles through the membrane take place simultaneously, enabling effective removal of the pollutants. The electrodes are arranged downstream of the membrane. With this arrangement, gases are produced from the electrodes to improve the electrolysis reactivity and the filtration efficiency of the membrane.
