The invention discloses an
ozone-catalytic functional
ceramic membrane, a preparation method thereof and a circulating
coating device, relates to the technical field of membrane material preparation, and aims at solving the problems that the
ozone-
catalytic efficiency of the existing
ceramic membrane is low, the integration of membrane
filtration and
ozone-catalytic functions cannot be realized, membrane
pollution cannot be effectively relieved and the like. By using a tubular
ceramic membrane as a carrier, single-component or multi-component
metal oxides are loaded through an impregnation method, then
manganese oxide dipping
coating solution is prepared, and a catalytic
coating layer is prepared on the surface of the membrane through a layer-by-layer dipping coating method. The invention aims at establishing a stereoscopic multistage catalyst
system, simultaneously improving the
catalytic efficiency of the separation layer and supporting layer of the
ceramic membrane and enabling an ozone-
catalytic effect to seep into the entire
ceramic membrane to fully realize the overall
catalytic effect. Compared with other
metal oxides,
manganese oxide has better adsorption and ozone-catalytic capacities, and while the ozone-catalytic capacity is improved, the membrane
pollution is effectively relieved and the integration of multiple functions such as
pollutant adsorption, ozone-catalytic oxidization and membrane separation is realized.
