摘要 介绍了国内外硅橡胶复合膜渗透蒸发脱除微量有机物的传质研究现状;提出了硅橡胶复合膜渗透蒸发串联传质阻力扩展模型;分析了渗透蒸发过程各部分传质阻力的影响因素,包括液相边界层、膜的致密皮层、膜的多孔支撑层;得到了便于工程设计的计算方法。结果表明,该模型对进一步的应用研究以及渗透蒸发过程的优化具有指导意义。 Author has introduced the present study situation of the mass transfer of removing the trace organic substance by silicon rubber compound membrane osmosis evaporation at home and abroad; has presented the extending mode/for mass transfer resistance in series used in the silicon rubber com- pound membrane osmosis evaporation; has analyzed the partial resistance in osmosis evaporation process, including the boundary layer of liquid phase, tight skin layer of membrane and effeeting factor for mass transfer resistance of porous supporting layer; has obtained the calculation method to facilitate en- gineering design. Result indicates that this model has the guiding significance for further application/study and optimizing osmosis evaporation process as well.
