摘　　要：　　通过在超声激励气隙式膜蒸馏系统上进行实验,研究了膜蒸馏通量的影响因素,结果表明:超声激励会使膜通量显著增大,最大膜通量达到110kg/(m2·h);提高料液流量可增大膜通量;减小间隙、增大温差,膜通量增加;随着盐溶液浓度增大,膜通量减小.Factors affecting the membrane flux were studied through the experiment made on a system of ultrasonic irradiation air-gap membrane distillation(AGMD).The result shows that the ultrasonic irradiation can greatly increase the membrane flux, and the maximum flux reaches 110 kg/(m^2·h).Besides, the augmentation of the flow rate of the feed can increase the membrane flux.And the membrane flux also increases when the air gap is reduced and the temperature difference is increased.The membrane flux decreases with the increase of the concentration of salting liquid.
