Technique for manufacturing metallic aluminum-carbon composite nanofiltration membranes by adopting waste light reflecting membranes

The invention discloses a technique for manufacturing metallic aluminum-carbon composite nanofiltration membranes by adopting waste light reflecting membranes. The technique is characterized in that the cheap waste light reflecting membranes are taken as raw materials, and the metallic aluminum-carbon composite nanofiltration membranes of different average pore sizes and pore size distributions can be manufactured through the adding number of binding agents and pore size control agents and carbonization conditions, wherein the metallic aluminum-carbon composite nanofiltration membranes are used for meeting different separation aims and are advanced in pore structure and good in separation performance. The problems that an existing metallic aluminum-carbon composite nanofiltration membrane is high in manufacturing cost, complex in technology and contaminative in organic solvent are solved, and the manufacturing method of the metallic aluminum-carbon composite nanofiltration membranes is low in cost, simple in
