However, the embodiments are only used as an explanation of the utility model and are not intended to limit the utility model.

[0021] like Figure 1 A low-energy rural rainwater recycling and utilization device is shown. The device is a semi-underground integrated steel structure device, including a pretreatment part, an artificial wetland part and a rainwater pool 301. The pretreatment part includes a grid channel 101, a collection pool 102 and a sedimentation pool 103 arranged from left to right. The grid channel 101 and the collection pool 102 are connected through a lower water hole, and the collection pool 102 and the sedimentation pool 103 are connected through an upper water hole.

[0022] like Figure 2 As shown, the artificial wetland part is a steel structure box, and an artificial wetland 201 is placed in the box. The artificial wetland 201 includes plants 202, planting soil 203, Φ8~12mm gravel 204, Φ14~22mm modified volcanic rock and expanded clay 205, Φ25~30mm gravel 206, first fine sand 207, and HDPE impermeable membrane 208, which are arranged from top to bottom. The water inlet and outlet ends at both ends of the artificial wetland 201 are paved with Φ50~80mm pebble layer 211, second fine sand 212, and HDPE impermeable membrane 208 from top to bottom. A sun shed 210 is arranged above the artificial wetland 201, and ventilation holes are reserved on both sides of the sun shed 210. The outlet end of the artificial wetland 201 is evenly provided with outlet pipes in the Φ50~80mm pebble layer, the straight section of the outlet pipe is located in the pebble layer, and the vertical section is located in the rainwater pool and extends upward to the height of the planting soil in the artificial wetland.
