Detailed Description

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The specific embodiment is as follows:
as shown in fig. 1, the movable artificial wetland simulator comprises a subsurface flow type artificial wetland part 1 and a surface flow type artificial wetland part 2, wherein the subsurface flow type artificial wetland part 1 sequentially comprises a first substrate layer 101, a first filler layer 102, a first water filtering layer 103 and a first water resisting layer 104 from top to bottom; the surface flow type artificial wetland part 2 comprises a second substrate layer 201, a second filler layer 202, a second water filtering layer 203 and a second water resisting layer 204 from top to bottom in sequence. A partition plate 3 is arranged between the subsurface flow type artificial wetland part 1 and the surface flow type artificial wetland part 2, the subsurface flow type artificial wetland part 1 is connected with a water inlet end 5, and the surface flow type artificial wetland part 2 is provided with a water outlet end 6; the first filtered water layer 103 and the second filtered water layer 203 are communicated with each other, and a vent pipe 7 is provided in the first filtered water layer 103 and the second filtered water layer 203.
The first substrate layer 101 and the second substrate layer 201 are used for planting the aquatic plants 4, the first substrate layer 101 is used for planting vascular bundle plants such as reeds or aquatic plants with developed root systems, and the second substrate layer 201 is used for planting vascular bundle plants such as reeds or emergent-submerged plants with developed root systems. The first substrate layer 101 is higher than the second substrate layer 201, that is, the submerged surface of the subsurface flow type artificial wetland section 1 is higher than the horizontal surface of the surface flow type artificial wetland section 2, so that water can flow over from the subsurface flow type artificial wetland section 1 to the surface flow type artificial wetland section 2.
Specifically, first filler layer 102 and second filler layer 202 both use a mixture of zeolite, rice husk, activated carbon, and ceramic particles. The first packing layer 102 and the second packing layer 202 are disposed in the packing grid 9, as shown in fig. 2, wherein the packing grid 9 is a frame structure in which a plurality of rectangular packing accommodating cavities are arranged in a rectangular array, and is built by bricks or by cement. The separator 3 is vertically arranged between the first filler layer 102 and the second filler layer 202, and separates the water on the surface of the subsurface flow type artificial wetland section 1 from the water on the surface of the surface flow type artificial wetland section 2.
The first water filtering layer 103 and the second water filtering layer 203 are both made of a mixture of pebbles, gravels, coarse sand and broken stones, the emptying pipe 7 is positioned at an opening at one end of the first water filtering layer 103, and a valve 8 is arranged at the other end of the emptying pipe.
The first water barrier layer 104 and the second water barrier layer 204 adopt impermeable films to prevent water from permeating downwards.
In this embodiment, the surrounding material of the movable artificial wetland simulator is made of a transparent material such as glass, so that the conditions of each layer of the internal subsurface flow type artificial wetland part and the surface flow type artificial wetland part can be seen, and the water treatment condition can be conveniently observed.
In the movable artificial wetland simulator in the embodiment, the hydraulic load is less than 1.3m in warm seasons3/m2D, the first matrix layer 101 of the subsurface flow type constructed wetland part 1 adopts soil and is planted with hygrophytes, the first filler layer 102 is arranged below the soil layer, and the first filler layer 102 adopts a mixture of volcanic rock, pumice and ceramsite; below the first packing layer 102 is a first water filtering layer 103 laid by pebbles; the second substrate layer 201 of the surface flow type artificial wetland part 2 adopts clean soil and is planted with hygrophytes such as canna, reed, candle and the like, and the lower second filler layer 202 and the lower second water filtering layer 203 are respectively the same as the first filler layer 102 and the first water filtering layer 103. The sewage flowing into the subsurface flow type artificial wetland part 1 can not seep down to form a water surface, and the first substrate layer 101 is utilized to carry out plant root system microorganismsThe organic matters in the sewage seeping downwards are degraded under the action of microorganisms attached to the materials in the first filler layer 102 and the first water filtering layer 103. Because the partition plate 3 separates the subsurface flow type artificial wetland part 1 from the surface flow type artificial wetland part 2, and only the first water filtering layer 103 is communicated with the second water filtering layer 203, sewage flows into the second water filtering layer 203 through the first water filtering layer 103 after being filtered and degraded downwards in multiple layers, under the condition that the water level of the water inlet end 5 is high to generate water pressure, water flows from bottom to top in the surface flow type artificial wetland part, namely the water flows out of the second water filtering layer 203, the second filler layer 202 and the second matrix layer 201 to form the water surface of the surface flow type artificial wetland part, the sewage degraded by the subsurface flow type artificial wetland part 1 is degraded again by the surface flow type artificial wetland part 2 to form purified water, and the purified water is discharged to a place to be used by the water outlet end 6. When the purified water surface of the surface flow type artificial wetland part 2 is too high or is flush with the diving surface of the subsurface flow type artificial wetland part 1, the valve 8 of the emptying pipe 7 needs to be opened, so that part of the water in the water filtering layer is discharged, and the water surface of the surface flow type artificial wetland part 2 is kept lower than the diving surface of the subsurface flow type artificial wetland part 1.
Similarly, in winter, the layers and degradation principles of the subsurface flow type artificial wetland part 1 and the surface flow type artificial wetland part 2 are the same as those in warm season, except that the aquatic plants 4 planted in the subsurface flow type artificial wetland part 1 are cresses, and the surface flow type artificial wetland part is planted with hygrophytes suitable for growing in winter.
In the movable artificial wetland simulator in the embodiment, the subsurface flow artificial wetland part 1 and the surface flow artificial wetland part 2 are separated by the partition plate 3, only the first water filtering layer 103 is communicated with the second water filtering layer 203, and the emptying pipe 7 is arranged. When sewage flows into the subsurface flow type artificial wetland part 1 through the water inlet end 5, in the process of flowing downwards, the degradation of the plant root system microorganisms of the first matrix layer 101, the degradation of the microorganisms attached to the materials in the first filler layer 102 and the first water filtering layer 103 and the synergistic effect of the degradation and the chemical degradation and the like in multiple aspects degrade organic matters in the sewage. Furthermore, the sewage degraded by the subsurface flow type artificial wetland part 1 is further degraded by the surface flow type artificial wetland part 2 from bottom to top, namely, the sewage is further degraded by the degradation of microorganisms attached to the materials in the second water filtering layer 203 and the second filler layer 202, the degradation of microorganisms in the plant root system of the second substrate layer 201, and the degradation of microorganisms in the biological membrane of the plant stem base immersed in the wastewater, so that the purified water on the upper part of the first substrate layer 101 in the surface flow type artificial wetland part 2 is formed.
In this embodiment, the first substrate layer 101 and the second substrate layer 201 are used for planting the aquatic plants 4, and there are various planting methods, namely, directly placing the roots of the aquatic plants 4 in the substrate layers for planting; secondly, planting the aquatic plants 4 in a planting pot filled with the matrix and placing the aquatic plants above the filler layer; thirdly, bricks are adopted to build a cultivation area, and matrixes such as soil and the like are placed in the cultivation area and aquatic plants 4 are planted in the cultivation area; fourthly, the aquatic plants 4 are planted in the planting pots filled with the matrix and are placed on brick pillars built by brick buildings.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
