摘　　要：本文研究了利用ZrO2悬浊液在多孔陶瓷管表面形成动态膜的条件。配置0.2～1.0g/L浓度范围的悬浊液,在50～200kPa的不同压力以及0.05～0.20m/s的错流速度等不同条件分别进行实验,获得最佳的涂膜条件为浓度0.7～0.8g/L,压力150kPa左右,错流速度0.1m/s左右。在此条件下制得的动态陶瓷膜具有良好的渗透性能、化学稳定性和截留能力,其纯水通量在0.2～0.3m3/m2·h,可用于工业废水及生活污水的深度处理。In this thesis, the optimum conditions for the formation of ZrO2 dynamic membrane on the porous ceramic support were studied. The experiments were carried out by circulating the colloid of ZrO2 at the concentrations of 0.2-1g/l, the applied pressures of 50-200kPa and cross-flow velocities of 0.05-0.2m/s respectively. And the data showed that the dynamic membrane was well formed at the concentration of 0.7-0.8m/l, the applied pressure of 150KPa or so and the cross-flow velocity of 0.1m/s or so. The permeating flux of pure water can reach 0.2-0.3m3/m2·h and the membrane can be used in the industrial and domestic wastewater treatment.
