The rainwater treatment collection box 20 is sequentially distributed with a stagnant water layer 5, a vegetation planting filter medium layer 6, a transition layer 7 and a treatment water retention layer 8 from the top to the bottom. The pipe 1 is connected with the water distribution pipe 4 through the diverter 2 and the water inlet pipe 3; when it rains, the rainwater in the raindrop pipe 1 enters the system through the diverter 2 and the water inlet pipe 3, and enters the water distribution pipe 4; one end of the water distribution pipe 4 is connected to the raindrop Pipe 1 is divided into water pipe 3, the other end is sealed, and the surface is evenly opened. After the rainwater enters the system from the water distribution pipe 4, when the water entry rate is greater than its downward infiltration rate, the rainwater collects on the surface and stays in the retention layer. The rainwater that penetrates downwards is filtered by the sandy loam in the vegetation planting filter medium layer 6, and continues to flow through the transition layer 7 composed of fine, medium and coarse sand mixed sand grains and enters the treatment water retention layer 8 covered with gravel, where it is collected and stored.

In this embodiment, a water level adjustment type overflow pipe 10 is also included. One end of the water level adjustment type overflow pipe 10 is connected to the treatment water retention layer 8, and the other end is connected to the building downspout through the system water outlet pipe 11, and the connection point is connected to the treatment water retention layer. The bottom height of 8 is equal to or lower than the bottom height of the treatment water retention layer 8; the bottom end of the treatment water retention layer 8 is provided with a water level adjustment type overflow pipe 10, and the other end of the water level adjustment type overflow pipe 10 is connected with the building downspout, and The connection point is at or below the height of the bottom of the treated water retention layer 8 . When the vertical pipe of the water level adjustment overflow pipe 10 is rotated to 90 degrees with the ground, the height of the top horizontal pipe of the water level adjustment overflow pipe 10 is flush with the top of the treated water retention layer 8 . When the vertical pipe of the water level adjustment type overflow pipe 10 is rotated to 0 degrees with the ground, the height of the nozzle of the water level adjustment type overflow pipe 10 is flush with the bottom end of the water retaining layer. The water level adjustment type overflow pipe 10 adjusts and controls the water storage depth in the water retaining layer by rotating.

In this embodiment, a processing perforated drainage pipe 9 and a backwashing pipe 12 are also arranged in the rainwater treatment collection tank 20 . The treatment perforated drainage pipe 9 is laterally arranged at the bottom end of the treatment water retention layer 8. After the rainwater after being processed by the vegetation planting filter medium layer 6 enters the treatment water retention layer 8, it can enter the drainage pipe from the holes on the treatment perforated drainage pipe 9. When the rainwater continues to flow in and exceeds the overflow water level, it will be smoothly drained by the water level adjustment type overflow pipe 10 through the drainage pipe. The top end of the backwash pipe 12 protrudes from the stagnant water layer 5 , and the bottom end is connected to the processing perforated drainage pipe 9 . When the system runs for a long time, the sand particles in the transition layer 7 gradually move down with the treatment water flow into the gravel of the treatment water retention layer, and may block the small holes on the treatment perforated drainage pipe 9 and reduce the perforated drainage pipe 9. drainage efficiency. At this time, a high-pressure water gun can be used to connect the backwash pipe 12, and the holes of the perforated drainage pipe 9 at the bottom of the system can be cleaned by water pressure, so as to ensure the smoothness of the holes on the perforated drainage pipe 9 and improve the drainage efficiency.

This wrapping method ensures that the contact area between the capillary geotextile layer 17 and the medium in the capillary irrigation vegetation planting layer 18 is maximized, and the speed and efficiency of capillary irrigation are enhanced.

The capillary irrigation vegetation planting layer 18 is located in the space surrounded by the capillary geotextile layer 17. Using the principle of capillary phenomenon, the water in the capillary water-retaining layer 15 is transported through the capillary geotextile layer 17 to the medium soil of all planting areas in contact with it. And with the help of vegetation growth, its roots continuously absorb water in the medium soil, so that the moisture difference between the soil around the drier root system and the soil around the more humid capillary geotextile layer 17 is formed, and the water in the capillary water retention layer 15 is continuously passed through the capillary geotextile. The cloth layer 17 moves toward the vegetation root system, and is finally absorbed and absorbed by the vegetation, finally realizing the optimization of the efficiency of rainwater recycling and reuse.

The ventilation, ventilation and water supply pipe 19 is vertically set up in the capillary planting box 21, so that the air layer 16 inside the system is always communicated with the external atmosphere, so as to ensure that the soil has air contact to avoid over-waterlogging. During the drought period, the capillary water-retaining layer 15 can also be supplemented with water through the pipe, so as to avoid the long-term drought affecting the growth of the vegetation.

The present invention uses specific examples to illustrate the principles and implementations of the present invention, and the descriptions of the above embodiments are only used to help understand the method and the core idea of the present invention; There will be changes in the specific implementation and application scope. In conclusion, the contents of this specification should not be construed as limiting the present invention.
