Abstract
Provided are a use of a Janus ceramic membrane in a dispersion-intensified bubble aeration process, and a preparation method of the Janus ceramic membrane. The Janus ceramic membrane is prepared as follows: a hydrophobic group is in situ grafted on a AlOceramic membrane as a substrate membrane through impregnation of a perfluoroalkylsilane (FAS) to prepare a hydrophobic ceramic membrane, and then a hydrophilic coating polydopamine (PDA) is formed through unilateral asymmetric surface deposition of dopamine (DA) to produce the Janus ceramic membrane for bubble aeration. The Janus ceramic membrane has asymmetric wettability. The Janus ceramic membrane not only has the unique properties of both hydrophilic and hydrophobic ceramic membranes, but also can improve the defects of hydrophilic and hydrophobic ceramic membranes to allow a synergistic effect, which improves the bubble aeration performance of the membrane in a gas-liquid dispersion process.
