The sedimentation purification tank 1 is a well body built with silica sand well bricks. The types and shapes of the silica sand well bricks can vary widely, and the present disclosure has no particular limitation thereto. For example, the shape of the silica sand well brick can be a regular hexagonal hollow structure, and its hollow structure can be used to collect and filter rainwater. In addition, the hollow part of the well brick can provide a good implantation environment for microorganisms in rainwater, making rainwater The number of free microorganisms is reduced to further purify rainwater. A plurality of regular hexagonal well bricks can be spliced to form a well unit with a honeycomb structure, and the water storage space is larger. The sidewall and bottom of the well body can be coated with the first geomembrane 16 . The first geomembrane 16 is a film layer with an anti-seepage effect, in order to prevent rainwater from being lost through external seepage. The type and thickness of the first geomembrane 16 can vary in a wide range, and the present disclosure has no special limitation thereto, as long as the effect of anti-seepage can be achieved.

The first geotextile 17 is arranged between the first soil layer 3 and the first silica sand permeable brick layer 4 to filter and purify the rainwater entering the sedimentation purification tank 1 from the soil layer.

A second soil layer 5 , a gravel layer 6 and a second silica sand permeable brick layer 7 can be arranged in sequence from top to bottom on the top of the micro-moisture pool 2 . The second soil layer 5 can grow green plants. The gravel layer 27 can be made of stone particles, which can prevent the soil in the soil layer from entering the micro-moisture pool 2 with the rainwater due to rainwater erosion. The particle size of the stone particles can vary in a wide range, and the present disclosure has no special restrictions on it. As long as the effect of preventing soil, gravel, etc. from entering the micro-moistening pool 2 can be achieved. The second silica sand permeable brick layer 7 is a permeable brick layer made of silica sand material, which is not particularly limited in the present disclosure, as long as it meets the requirement of water permeability. The type and shape of the second silica sand permeable brick layer 7 may be the same as or different from the first silica sand permeable brick layer 4, and the same silica sand permeable bricks are preferably used.

In order to realize the water retention effect of the purified rainwater on the planting plants in the second soil layer 5 in the micro-moist pool 2, a solar panel 10 is arranged on the second soil layer 5, and a submersible pump 11 is arranged in the micro-moist pool 2, so The gravel layer 6 is provided with a straight pipe 12 horizontally running through it, and a plurality of micro-moisture rods 13 are inserted into the straight pipe 12. The solar panel 10 is connected to the submersible pump 11 through a first cable 14. The submersible pump 11 is connected with the straight pipe 12 through a water supply pipeline 15 . The solar panel 10 serves as an energy supply device to provide the electric energy required for the submersible pump 11 to work. The submersible pump 11 can extract the purified rainwater in the micro-moisture pool 2 into the straight pipe 12, and the micro-moisture rod 13 absorbs the rainwater in the straight pipe 12 to diffuse In the second soil layer 5, the water retention effect on the second soil layer 5 is realized, and the purified rainwater can make plants grow well. The material of the micro-moisturizing stick 13 can be a conventional material with water absorption and moisturizing effects, which is not specifically limited in the present disclosure. The wetting bar 13 is partly located in the gravel layer 6 and partly in the second soil layer 5, and the gap between the stones in the gravel layer 6 can make the rainwater absorbed by the wetting bar 13 more evenly flow into the second soil layer 5 diffusion. The quantity of wetting stick 13 can be adjusted according to actual needs.

The micro-moist pool 2 is a well body built with silica sand well bricks. The types and shapes of the silica sand well bricks can vary widely, and the present disclosure has no particular limitation thereto. For example, the shape of the silica sand well brick can be a regular hexagonal hollow structure, and its hollow structure can be used to collect and filter rainwater. In addition, the hollow part of the well brick can provide a good implantation environment for microorganisms in rainwater, making rainwater The number of free microorganisms is reduced to further purify rainwater. A plurality of regular hexagonal well bricks can be spliced to form a well unit with a honeycomb structure, and the water storage space is larger. The silica sand well bricks of the micro-moisture tank 2 can be the same as or different from the silica sand well bricks of the sedimentation purification tank 1, and the same silica sand well bricks are preferably used. The side wall and bottom of the well body can be coated with the second geomembrane 18 . The second geomembrane 18 is a film layer with an anti-seepage effect, in order to prevent rainwater from being lost through external seepage. The type and thickness of the second geomembrane 18 can vary in a wide range, and the present disclosure has no special limitation thereon, as long as the anti-seepage effect can be achieved. The type of the second geomembrane 18 may be the same as that of the first geomembrane 16 or may be different, and the same geomembrane is preferably used.

Furthermore, in order to better achieve the effect of air permeability and anti-seepage, the air permeability and anti-seepage performance of the second air-permeable and anti-seepage sand layer 20 is better than that of the first air-permeable and anti-seepage sand layer 19 .

In order to improve the oxygen content of the rainwater in the wetting pool 2 and further ensure that the rainwater diffused to the second soil layer 5 by the wetting bar 13 can make the plants grow well, an aeration device is also arranged in the wetting pool 2 22 , the solar panel 10 is connected to the aeration device 22 through a second cable 23 . The aeration device 22 is a conventional device that can fill the water with oxygen to increase the oxygen content of the water body, and there is no special limitation in this disclosure. The solar panel 10 provides electric energy for the aeration device 22 . Oxygen is filled into the rainwater in the micro-moisture pool 2 through the aeration device 22, and the oxygen content of the purified rainwater is higher, and then the submersible pump 11 extracts and the micro-moisture rod 13 diffuses into the second soil layer 5, It can provide sufficient oxygen for the root system of the plant, so that the plant can grow well. Sufficient oxygen can also enable microorganisms present in rainwater to consume organic impurities in the water, further maintaining good water quality.

In order to achieve the balance of pressure inside and outside the micro-moist pool 2 so that the submersible pump 11 can work normally, the micro-moist pool 2 can also include a vertical pipe 24 penetrating from the second soil layer 5 to below the water level in the micro-moist pool 2, so The first cable 14, the second cable 23 and the water supply pipeline 15 can pass through the standpipe 24. The position of the pipe top of the standpipe 24 can be slightly higher than the second soil layer 5, so as to avoid the erosion of rainwater and cause the soil to enter the wetting pool 2 from the standpipe 24. The part of the standpipe 24 below the second silica sand permeable brick layer 7 is preferably an open structure, which allows oxygen to pass through the standpipe 24 to enter below the second silica sand permeable brick layer 7 and above the water level in the wetting pool 2 part, further increasing the oxygen content of rainwater. The material of the standpipe 29 can be selected from those conventionally used in the art, for example, it can be a PVC pipe.
