[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 7The utility model provides a technical solution: an artificial wetland water purification structure, including a slope 1, a reinforcement layer 2, a filling layer 3, a planting soil layer 4, a planting hole plate 5, and plants 6. The reinforcement layer 2 is laid on the slope 1, the filling layer 3 is laid on the reinforcement layer 2, the planting soil layer 4 is laid on the filling layer 3, the planting hole plate 5 is laid on the planting soil layer 4, the plants 6 are planted in the planting soil layer 4, and the plants 6 extend from the holes on the planting hole plate 5. A water storage tank 7 is provided on the reinforcement layer 2. The water storage tank 7 is adjacent to the filling layer 3, the planting soil layer 4, and the planting hole plate 5. A water inlet 8 and a water seepage port 9 are opened on the side of the water storage tank 7 facing the filling layer 3. The height of the water inlet 8 is higher than the upper surface of the planting hole plate 5. The seepage port 9 is aligned with the filler layer 3, and the slope 1 is reinforced by the reinforcement layer 2. Then, the filler layer 3 is set on the reinforcement layer 2 to create a microbial environment and to raise the slope 1. A planting soil layer 4 and a planting hole plate 5 are set for planting plants 6. A water storage tank 7 is set to collect overflowing water. The water in the water storage tank 7 is infiltrated into the filler layer 3 again through the seepage port 9 on the water storage tank 7 and then purified. When the water flow is large, the overflowing water enters the water storage tank 7 from the water inlet 8. When the water flow is small, under the action of the water pressure difference, the water in the water storage tank 7 infiltrates into the filler layer 3 from the seepage port 9. After the filler layer 3 is full of water, the water overflows to ensure that the plants 6 have enough water to survive;

[0022] The packing layer 3 includes a water seepage frame 301 and a filler soil 302. The filler soil 302 is filled in the water seepage frame 301. The front and back of the water seepage frame 301 are provided with water seepage holes. The water seepage frame 301 is provided to prevent the filler soil 302 from being washed away by water. The water seepage holes ensure that the purified water flows out and the water in the water storage tank 7 flows into the packing layer 3.

[0023] The height difference between the lowest point of the water inlet 8 and the highest point of the planting hole plate 5 is 50MM, ensuring that a certain amount of water can be retained at the plant 6. There are multiple water inlets 8, which are evenly spaced on the water storage tank 7 to increase the water inlet channel and ensure that water does not overflow above the water storage tank 7;

[0024] The seepage opening 9 is lined with porous bricks 10, which block the entire seepage opening 9 to prevent dirt, stones, etc. from entering the water storage tank 7;

[0025] The interior of the water storage tank 7 is paved with a water-permeable membrane 11, which is attached to the porous bricks 10 to prevent mud and sand from entering the water storage tank 7;

[0026] The inner wall of the water inlet 8 is fixedly installed with an interception plate 12 and an interception plate 2 13. The interception plate 12 and the interception plate 2 13 are both semicircular plates, and the interception plate 12 and the interception plate 2 13 are respectively fixed on the bottom inner wall and the top inner wall of the water inlet 8. The interception plate 12 and the interception plate 2 13 are set to block the water inlet 8 and are used to intercept stones and soil accompanying the water flow.

[0027] Working principle: When in use, when the water flow is large, the water quickly overflows to the water inlet 8. At this time, the filler layer 3, the planting soil layer 4, and the planting hole plate 5 are all full of water. The water flows from the water inlet 8 into the water storage tank 7. At this time, the water pressure difference inside and outside the water storage tank 7 is small, ensuring that the water storage tank 7 can store water. When the water flow is small, a large amount of water evaporates from the filler layer 3, the planting soil layer 4, and the planting hole plate 5. At this time, the water pressure difference between the water storage tank 7 and the filler layer 3 is large. The water in the water storage tank 7 seeps into the filler layer 3 from the seepage port 9, seeps into the filler layer 3 with the water flow, and then overflows upward to the planting soil layer 4 and the planting hole plate 5, ensuring that the plants 6 can always have enough water to survive.

[0028] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
