The top of the accommodating chamber 61 is communicated with the top end of the condensation pipe 62, and the bottom end of the condensation pipe 62 is communicated with the water conduit 53. During the sun exposure in the daytime, the water in the pollutants is evaporated and condensed into distilled water in the condensation pipe 62, and the distilled water flows into the water guide pipe 53 of the planting device 5 from the bottom of the condensation pipe 62 to supplement the water for the planting device 5. When the recycling bag 65 in the accommodating cavity 61 is filled with pollutants, the distillation device 6 forms a strong temperature difference with the hot environment of the desert, and further cools the plants around the distillation device 6. And the distillation device 6 containing the pollutants can also shield nearby plants from exposure to the sun. At night, dew condensed on the outer side wall of the distillation unit 6 flows to the nearby planting devices 5 due to sudden temperature drop, so that more water is supplied to plants in the planting devices 5. The top of the distillation apparatus 6 has a second opening 63 for exposing the top end of the condensation pipe 62 and the accommodating cavity 61 to the outside, and a second cover 64 covering the second opening 63, wherein the second cover 64 is provided with a lifting handle 64a, so that when the recovery bag 65 and the pollutants in the recovery bag 65 need to be replaced, the second cover 64 can be opened to facilitate the taking out or putting in of the recovery bag 65. The bottom of the distillation device 6 is provided with a base 66, the base 66 is provided with a through groove 66a arranged along the horizontal direction, two ends of the through groove 66a penetrate through two ends of the base 66, the base 66 can be lifted by a mechanical lifting or a forklift, the distillation device 6 containing pollutants such as heavy pollutants or radioactive water is suitable for being accommodated inside, and the distillation device 6 generally needs to be lifted by a mechanical lifting or lifting for transportation.
