▎ 摘　　要

NOVELTY - A membrane structure (30) of flat membrane or hollow fiber membrane form comprises a carbon nanomaterial (10) and sodium (Na) super ionic conductor (NASICON)-series ceramic particles (20), where the carbon nanomaterial and NASICON-series ceramic particles are interwisted to form a three-dimensional mesh-shaped structure. USE - A membrane structure of flat membrane or hollow fiber membrane form used for water treatment processing apparatus (claimed). ADVANTAGE - The limited delivery of ions through spreading and a reduction of a total ion adsorption capacity attributable to the pre-adsorption of polyvalent positive ions are improved by applying a water-permeable membrane structure and NASICON-series ceramic particles. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) water treatment processing apparatus comprising a reactor for a capacitive deionization process using a membrane structure (30) of flat membrane or hollow fiber membrane form, comprising a carbon nanomaterial (10) and sodium (Na) super ionic conductor (NASICON)-series ceramic particles, as a positive ion adsorption electrode for a capacitive deionization process, where the positive ion adsorption electrode and a negative ion adsorption electrode are disposed at a given interval; and (2) fabricating a membrane structure which involves (a) fabricating NASICON-series ceramic particles (20); and (b) forming a membrane structure of a flat membrane or hollow fiber membrane form in which the NASICON-series ceramic particles and a carbon nanomaterial have been intertwisted. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the method of fabricating a membrane structure.
