Abstract：

The hydrophobic ceramic membrane has outstanding advantages in the field of membrane distillation, which can expansion of membrane distillation application scenarios. In this paper, hydrophobic α-Al2O3 ceramic membrane was prepared by a new method. The morphological characteristics, hydrophobic properties, grafting effectiveness and wide temperature range thermal stability were characterized. The influence of temperature difference on the driving force of per unit temperature difference was revealed, and the ion rejection rate of hydrophobic ceramic membrane distillation process was determined. The results show that the hydrophobic membrane surface forms a coarse structure, and the hydrophobic performance is excellent. The 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane on the surface of the hydrophobic film played a hydrophobic role and had good high temperature thermal stability. The per unit temperature difference driving ability (ec) based on the raw water temperature changes negatively with the temperature difference (△T) according to the −0.7356 power function law, while the per unit temperature difference driving ability (er) based on the cooling water temperature changes positively with the △T according to the 1.74589 power function law. The retention rate of all tested ions by the hydrophobic ceramic membrane distillation process was greater than 99.96 %. This study is of great significance to guide the formulation of hydrophobic ceramic membrane distillation operation strategy.
