The invention discloses a bionic-type suspended acceleration evaporator. The bionic-type suspended acceleration evaporator comprises an evaporator body, wherein the evaporator body comprises a semipermeable membrane surface layer, a water absorption inner container, a suspended inner container and a divergent branch, the semipermeable membrane surface layer is arranged on the surface of the water absorption inner container; the water absorption inner container is internally provided with the suspended inner container used for providing a buoyancy force for the evaporator body; and the divergent branch used for enlarging evaporation area and providing an osmotic pressure is mounted on the water absorption inner container. The bionic-type suspended acceleration evaporator has the beneficial effects that ecological environmental protection is realized, an energy source does not need to be externally connected, maintenance is less, operation is simple, applicability is wide, the target of acceleration of wastewater evaporation with relatively low cost can be realized, and finally the aim of recycling most of wastewater into production is realized.
