The utility model discloses a desulfurization waste water zero release processing system, waste water get into to receive through the intensive softening of tubular micro -filtration membrane and strain the separation that monovalence ion and divalent ion were accomplished to the diffusion barrier. According to fresh water side and dense water side material properties, it is further concentrated that the power consumption drives the ionic membrane, and furthest's the vaporization system that reduces handles scale and scaling tendency. The evaporation crystallized region adopts the MVR crystallizer to obtain salt crystal, has finally realized waste water and salt crystal's utilization, has saved the investment simultaneously, is showing and is reducing the waste water running cost, can really realize the zero release of waste water.
