Abstract
An electrochemical membrane module for selectively removing pollutants and a preparation method thereof are provided. A Ti/SnO2—Sb substrate electrode is coated with a MI—TiO2 sol-gel by means of a dip-coating method, and then sintered to obtain a molecular imprinting type Ti/MI—TiO2/SnO2—Sb coated electrode; the coated electrode is adhered to a ceramic micro-filtration membrane using epoxy resin glue to obtain a Ti/MI—TiO2/SnO2—Sb MI-anodic conductive composite membrane; the MI-anodic conductive composite membrane is used as an anode, and a titanium mesh is used as a cathode, so that the electrochemical membrane module capable of selectively removing pollutants is obtained. The invention effectively combines an electrochemical micro-filtration membrane and a molecular imprinting technique. When the electrochemical membrane module is used, suspended particles and refractory organics in the sewage are removed, and a highly selective removal of certain refractory pollutants can be achieved.
