| 摘 要： | 应用新型的硼硅酸多孔玻璃膜（porous glass)于错流超滤（cross-flow ultrafiltration）系统中，分离出30－300nm有机质胶体。分别试验孔径为30nm、50nm和100nm等多孔玻璃膜对一些标准有机大分子的截留率。实验结果显示过滤溶液的酸度、温度、盐度对该分离膜的分离性能影响甚微。

| Abstract: | The porous glass membrane produced by Sumica Chemical Company of Japan was applied to cross flow ultrafiltration. In different filtering conditions including pressure, circle flow rate, acidity, temperature and salinity, the behaviors of porous glass membrane were investigated. The results showed the membrane is suitable to isolate the organic colloids from nature water. The retention varied with the pore size of porous glass membrane used. |

| Keywords: | porous glass membrane cross|flow ultrafiltration dissolved organic colloids retention |
