The invention provides a magnetic polyurethane photoproduction coupling filler and a preparation method thereof, wherein the filler is a magnetic polyurethane sponge with a photocatalytic material loaded on the surface, and the photocatalytic composite material is a photocatalyst/modified magnetic powder composite material prepared by a sol-gel method. The magnetic polyurethane photoproduction coupling filler has magnetism, hydrophilicity, roughness and photocatalytic activity, integrates oxidation and biochemical processes, and provides a new idea for treating low-concentration refractory wastewater. |
