Abstract: The present application provides a hydrophilic and hydrophobic composite packing-based rotating packed bed and a system. A hydrophobic packing and a hydrophilic packing are formed into a composite packing. When said packing cuts liquid, the hydrophobic packing can sufficiently disperse the liquid so as to make the dispersion of the liquid in the packing zone more uniform, and the wettability of the hydrophilic packing allows the liquid to spread sufficiently so as to increase the wetting efficiency of said packing. The phenomenon of droplet aggregation caused to liquid in a single hydrophobic packing zone and the phenomenon of reduction of liquid turbulence caused to liquid in a single hydrophilic packing zone can be avoided. Therefore, applying a hydrophilic and hydrophobic composite packing to a rotating packed bed can further improve the mass transfer and mixing performance thereof.
