[0035] In this embodiment, the lower end of the water outlet 18 is provided with a water outlet 19. The lower end of the water outlet 19 is connected to the connecting pipe 29 by multiple bolts. The other end of the connecting pipe 29 is connected to the water inlet 28 by multiple bolts. The water inlet 28 is located on the upper right side of the wastewater distillation tank 22.

[0036] The wastewater distillation tank 22 has a cylindrical upper end and a conical lower end.

[0038] In this embodiment, the lower end of the drive unit 25 is connected to the stirring shaft 211.
