Abstract：

Membrane flux is an important index to measure membrane distillation technology. Low membrane flux seriously limits the industrial development of membrane distillation technology. From the perspective of phase change coupling and countercurrent heat transfer coupling and the thermal diffusion coupling of steam molecules in membrane pores, the phase change heat and mass transfer process at hot material side, countercurrent heat transfer process in membrane distillation system and vapor molecules in membrane are analyzed respectively,and the relationship between the heat and mass transfer process and the membrane flux is established. It is concluded that the spontaneous vapor molecular transfer process drives the non-spontaneous heat transfer process. When the mass transfer process is strengthened, the vapor molecular transfer rate increases, resulting in the increase of membrane flux, the enhancement of heat transfer in membrane distillation system helps to weaken the temperature polarization, accompanied by the increase of temperature gradient on both sides of the membrane surface,at the same time, the relationship also shows that the decrease of membrane thickness is beneficial to the increase of membrane flux
