Zusammenfassung:The invention discloses preparation and application of a high-flux flat ceramic-based carbon membrane, and belongs to the technical field of membrane-method water treatment. A high-flux flat ceramic membrane is prepared by adopting a phase inversion and high-temperature sintering technology, a nano-catalyst is loaded by adopting an impregnation-calcination-reduction method, and synthesis conditions of carbon nanotubes are optimized, so that a carbon nanotube membrane formed on a flat ceramic membrane carrier has higher network porosity and more uniform distribution; the formed carbon nanotube net structure film not only has high porosity, but also ensures good conductivity and light absorption performance. The composite membrane is used for treating saline water with different concentrations through an interface heating membrane distillation process by virtue of an external light source or a power supply, and compared with a traditional membrane distillation process, the composite membrane has higher water fl
