Title:
MEMBRANE-COUPLED ADVANCED ELECTRO-OXIDATION METHOD, WATER TREATMENT APPARATUS THEREFOR, AND WATER TREATMENT SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/093179
Kind Code:
A1
Abstract:
Provided in the present invention are a membrane-coupled advanced electro-oxidation method which simultaneously performs an electrode reaction and membrane filtration, a water treatment apparatus using the same, and a water treatment system using the same. The present invention comprises: a step of forming a separator electro-oxidation tank in which an electrode and a separator are combined; a contaminant receiving step of receiving contaminants in the separator electro-oxidation tank; and a water treatment step of supplying power to the electrode to decompose the contaminants and simultaneously separate particles using the separator, wherein the electrode is disposed on a lower side of the separator in the step of forming the separator electro-oxidation tank, and gas generated in the electrode causes a flow of fluid in the vertical direction in the water treatment step, thereby improving the contact efficiency between a reaction liquid and the electrode and removing the contaminants adhering to the surface of the separator. As such, the present invention has advantages in that as the steps of decomposing the contaminants using the electrode and separating the particles using the separator are performed at the same time, it is possible to effectively remove the contaminants, and in that as the electrode is positioned below the separator, the reactivity of electrolysis can be improved by the gas generated in the electrode and the filtration efficiency of the separator can be improved.
