| 摘 要： | 通过量纲分析，建立了氧化铝陶瓷膜在处理高浊度水时，影响膜通量变化的压力、膜孔径、膜管长度、膜面流速、原水浊度、工作时间以及温度等因素之间的关联式．并通过试验，针对膜通量的快速衰减期以及相对平缓期，分别分析求解了各项系数．通过分析比较发现，20℃时关联式相对于实测数据的平均相对误差仅为1．5％，由此证明利用量纲分析得出的膜通量衰减关联式较好地反映了实验结果．

| Abstract: | Dimensional analysis is used to establish Al_2O_3 ceramic membrane flux equation of the elements such as pressure, bore diameter of membrane, length of membrane tube, velocity of membrane surface flow, turbidity,work time and temperature, during the process of high turbidity water treatment. For the fast attenuation phase and relative steady phase, various factors is obtained by analyzing. Further analysis shows, the average fractional error between the related equation and the actual experimental date is 1.5% in 20 . The related equation based on dimensional analysis can properly coincide with the actual result. |
