Abstract: In order to improve the packing density of ceramic membrane and simplify the preparation process,the ceramic ultrafiltration membrane is prepared by the suspended particles dip coating method using the honeycomb ceramics with high packing density and low cost as matrix,nano alumina dispersion solution as the coating liquid.The non-loaded alumina membrane is analyzed by means of TG-DSC,which shows that the suitable sintering temperature of composite membrane is at 500℃.The surface and cross section morphology of the membrane are observed via SEM.The results show that the surface of membrane is basically intact,and the membrane can effectively remove the particles with diameter larger than 30 nm in suspension.When the operating pressure is 0.1 MPa,the pure water flux of the composite membrane is 200 L/(m2·h).The area/volume ratio of composite membrane reaches 1 670.3,more than 4 times that of the 19 channel ceramic membrane.It can effectively reduce the volume occupied by the unit membrane area.
