| 摘 要： | 对用液／液膜吸收法处理水中氨氮过程中，伴生的水渗透蒸馏的抑制方法进行了研究．结果表明：料液中氨氮浓度高，其水的渗透蒸馏通量小；料液中含有一定的盐分，可抑制水的渗透蒸馏；适当降低料液温度，提高吸收液温度，对抑制料液水的渗透蒸馏有一定作用，其过程对传质系数影响不大。液／液膜吸收法处理含有一定盐分的，具有高浓度氨氮的废水，是可行的，具有广泛的工业应用价值。

| Abstract: | The inhibiting method of osmosis distillation accompanied in the course of treating ammonia wastewter by liquid/liquid membrane absorption was studied. The results showed that the higher the ammonia concentration in feed, the smaller the flux of osmosis distillation; the feed containing a certain salts can inhibt the water osmosis distillation; properly lowering temperature of feed and heightening the temperature of absorption liquid have a certain inhibiting against osmosis distillation of feed; the process has no obvious influence on mass transfer coefficient. The treatment of high strength ammonia wastewater with a certain salinity by liquid/liquid membrane adsorption is feasible and has wide value of industrial application. |
