[0002] Artificial wetlands are artificial ecosystems that simulate natural wetlands. They are surface water bodies similar to swamps that are artificially constructed and controlled. Similar to natural swamps, they mainly use the physical, chemical, and biological synergistic effects of soil, artificial media, plants, and microorganisms to treat sewage and sludge.

[0003] In the current traditional modular artificial wetlands, the stacking density of the filler module is approximately 1400kg to 2700kg / cubic meter, and the construction method of stacking small-particle fillers is usually adopted, which makes it difficult to replace the regulating filler after it is blocked or the purification capacity decreases.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] The present invention is further described in detail below in conjunction with specific embodiments, and these embodiments cannot be understood as limiting the scope of protection claimed by the present invention.

[0037] In the description, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0038] This application proposes a constructed wetland filler module, such as Figure 1 As shown, the packing module includes a packing block 1, which is an integrated block-shaped object with length, width and height. It also includes a packing column assembly, which is arranged in the packing block 1, and the packing column assembly includes a plurality of packing columns 2, which are arranged at intervals and extend along the height direction of the packing block 1, and the packing columns 2 can accommodate adjustable packing.

[0039] Specifically, preferably, the filler block 1 adopts the technology of lightweight and integrated wetland filler, and the filler block 1 itself becomes a whole and has certain supporting performance. The density of the filler block 1 is 30-60 kg / m3, which is much lower than the density of 1400 kg-2700 kg / m3 of the traditional artificial wetland filler block. The filler block 1 is convenient to punch holes, so that the filler column can be placed conveniently.

[0040] In some other embodiments, this lightweight filler block manufacturing technology may not be used, and wetland fillers made of other materials may be used for integrated molding.

[0041] The artificial wetland filling module of the present application adopts the filling lightweight technology by designing an integrally formed filling block and its matching with the filling column. The filling block has a low density and the filling block itself has supporting properties, which greatly reduces the weight of the artificial wetland filling module, thereby facilitating the installation of the artificial wetland and the cleaning of the filling. It can be dismantled at low cost when the wetland is renovated, and the filling column can be easily installed and disassembled in the filling block.

[0042] Preferably, the filler block 1 is made into an integrated block-shaped cube as the main body of the filler module, such as Figure 1 and Figure 2 In a general assembled artificial wetland module, the size of the filler block 1 is usually 2000 mm×800 mm×1000 mm.

[0043] In the present application, the regulating filler built into the packing column 2 mainly refers to some types of special fillers that have a significant improvement in wetland biochemical performance, including but not limited to carrier microbial fillers, slow-release carbon source fillers, pyrite, etc. The regulating filler can also be called specific filler, high-performance filler, etc.

[0044] like Figure 2 As shown, the packing block 1 includes a top surface 4, a bottom surface 5 and a plurality of cylindrical holes 3, wherein the cylindrical holes 3 are provided on the top surface 4 or the bottom surface 5, and may also penetrate the top surface 4 and the bottom surface 5. A plurality of packing columns 2 are respectively inserted into the plurality of cylindrical holes 3, and the cylindrical holes 3 match the shapes of the packing columns 2 contained therein. During the assembly process, a hole is first punched on the packing block 1, and then the packing column 2 is directly inserted into the packing block 1. It is also relatively convenient to take out the packing column 2 from the packing block 1.

[0045] The artificial wetland filler module of the present application is provided with multiple filler columns for accommodating regulating fillers, so that one filler module can accommodate one or more regulating fillers. The regulating filler can greatly improve the biochemical performance and chemical adsorption performance of the wetland, solving the problem that traditional artificial wetlands cannot effectively configure high-performance regulating fillers, and the regulating fillers are difficult to efficiently replace and replenish after being saturated with adsorption.

[0046] Preferably, if Figure 1 As shown, plants 10 may be planted on the filler block 1 . The plants 10 are located above the filler block 1 and may be planted on the top surface 4 .

[0047] In the present application, generally speaking, one packing column contains one type of regulating packing, and multiple packing columns 2 in the packing block 1 may contain the same type of regulating packing or may contain multiple types of regulating packing. There is no limitation on how many packing columns each type of regulating packing can be contained in.

[0048] The type, density and dispersion arrangement of the packing columns in the packing module need to be determined by comprehensive calculation based on the project location, climate characteristics, water inflow properties, and treatment capacity of the wetland construction. This allows the artificial wetland to achieve maximum effect in special situations such as treating different incoming water and large changes in water quality. The number of packing columns can be flexibly increased or decreased, the type of packing can be changed, or the arrangement of the packing columns can be changed according to needs through theoretical calculations.

[0049] The artificial wetland filler module of the present application is designed to flexibly increase or decrease the number of filler columns, or change the type of adjustable filler according to different wetland influent water qualities, thereby ensuring a more stable treatment effect under various special influent conditions, solving the problem that the treatment effect of the artificial wetland is greatly affected by the influent water quality, and making it more widely applicable.

[0050] like Figure 3As shown, it is a preferred packing column structure design. The packing column 2 includes a water-permeable tube 6, which is a rigid or flexible tubular structure, and the tube wall of the water-permeable tube 6 has a mesh structure or a porous structure for easy water permeability. Preferably, the water-permeable tube 6 can be woven or thermoformed with plastic filaments, and the minimum pore size on the tube wall can reach about 2mm. The water permeability of the water-permeable tube 6 can reach more than 60%. Thereby, the effective ingredients for adjusting the packing in the packing column 2 can be diffused out through the water flow to produce a biochemical effect on the artificial wetland. The water permeability can also be changed by changing the pore size as needed.

[0051] In some other embodiments, the packing column 2 may not include a water-permeable tube. For example, the regulating packing may be directly made into an integrated column to form a packing column.

[0052] In the present application, the cross section of the water-permeable pipe 6 can be circular or polygonal, so that the filler column is a cylinder or a polygonal column, and the polygonal column is preferably a triangular prism or a quadrangular prism.

[0053] The packing column 2 further includes two plugs 7, which are respectively located at the two ends of the water-permeable pipe 6, and a receiving space is formed between the water-permeable pipe 6 and the two plugs 7, and the adjusting packing is received in the receiving space. The two plugs 7 are fixedly connected to the water-permeable pipe 6 to prevent the adjusting packing from leaking out from the two ends of the water-permeable pipe 6.

[0054] Preferably, in terms of the size of the packing block 1 in this embodiment, if the packing column 2 is a cylinder, the diameter is between 20 mm and 200 mm, and if the packing column 2 is a polygonal column, the cross-sectional side length is between 20 mm and 200 mm. Preferably, the wall thickness of the water-permeable pipe 6 is between 1 mm and 12 mm.

[0055] Preferably, the length of the packing column 2 accounts for more than 50% of the height of the packing block 1 .

[0056] like Figure 5 As shown, the present application also proposes an artificial wetland, comprising a plurality of filler modules according to the above design, wherein the plurality of filler modules are laid flat to form an artificial wetland.

Figure 1 , Figure 2 and Figure 4 As shown, the packing column assembly includes a first packing column 8 containing a first functional packing, the number of the first packing columns 8 is between 3 and 5, and the plurality of first packing columns 8 are arranged along the length direction of the packing block 1. The figure shows a case where there are three first packing columns 8.

[0059] In addition, the packing column assembly further includes a second packing column 9 for accommodating a second functional packing, the number of the second packing columns 9 is 1 to 2, and the diameter of the second packing column 9 is greater than the diameter of the first packing column 8. The figure shows a case where there are two second packing columns 9. The two second packing columns 9 are arranged along the length direction of the packing block 1, and are not in the same straight line with the plurality of first packing columns 8.

[0060] The artificial wetland filler module of the present application solves the problem of finely proportioning different types of regulating fillers in artificial wetlands by designing the arrangement of different types of filling columns such as the first filling column and the second filling column to adapt to different types of regulating fillers.

[0061] Embodiment 2:

[0062] The artificial wetland packing module in Example 2 is basically the same as the packing module in Example 1, except that the packing column assembly only includes a first packing column 8 for accommodating a first functional packing, the number of the first packing columns 8 is between 3 and 5, and the plurality of first packing columns 8 are arranged along the length direction of the packing block 1. The figure shows the situation of three first packing columns 8.

[0063] In summary, from the above description, it can be seen that the above-mentioned Embodiment 1 and Embodiment 2 of the present invention achieve the following technical effects:

[0064] 1. The artificial wetland filler module of the present application is provided with multiple filler columns for accommodating regulating fillers, so that one filler module can accommodate one or more regulating fillers. The regulating filler can greatly improve the biochemical performance and chemical adsorption performance of the wetland, solving the problem that traditional artificial wetlands cannot effectively configure high-performance regulating fillers, and the regulating fillers are difficult to efficiently replace and replenish after being saturated with adsorption.

[0065] 2. The artificial wetland filler module of the present application is designed to flexibly increase or decrease the number of filler columns or change the type of adjustable filler according to the different wetland influent water qualities, thereby ensuring a more stable treatment effect under various special influent conditions, solving the problem that the treatment effect of the artificial wetland is greatly affected by the influent water quality, making it more widely applicable.

[0066] 3. The artificial wetland filler module of the present application is designed with an integrally formed filler block and its matching mode with the filler column, so that the filler block itself has supporting performance and the filler column can be easily installed and removed in the filler block.

[0067] 4.

[0068] Embodiment 3:

[0069] This embodiment proposes an artificial wetland, including a plurality of filler modules according to the embodiments 1 and 2, wherein the plurality of filler modules are laid flat to form an artificial wetland.

The first packing module 11 includes a plurality of first packing columns 8, preferably three first packing columns 8. The second packing module 12 includes a plurality of first packing columns 8 and second packing columns 9, preferably three first packing columns 8 and two second packing columns 9.

[0071] In addition, the distribution density of the second filler modules 12 in the artificial wetland is lower than that of the first filler modules 11. In the figure, the second filler modules 12 are dispersedly arranged between the densely arranged first filler modules 11.

[0072] According to the improvement effect of regulating fillers on wetlands, regulating fillers can be divided into concentrated fillers and dispersed fillers. Concentrated fillers are mainly suitable for specific fillers that require high density to improve their overall effect. They are generally made into large filler columns with a larger diameter and contain more concentrated fillers. They need to be distributed in small quantities in artificial wetlands. Dispersed fillers are mainly suitable for specific filler types that need to be widely distributed and mixed. They are generally made into small filler columns with a smaller diameter and need to be dispersed in large quantities in wetlands. Based on this, a first filler column 8 is designed to accommodate dispersed fillers, and a second filler column 9 is designed to accommodate concentrated fillers.

[0073] In summary, from the above description, it can be seen that the above-mentioned embodiment 3 of the present utility model achieves the following technical effects:
