In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0056] This utility model provides a small-scale modular artificial wetland device for simulating wetlands. It can typically be placed along roadsides, on rooftops, and in courtyards. The term "small-scale artificial wetland" refers to a device suitable for decentralized, low-flow scenarios, including road rainwater purification, rooftop water collection and treatment, and decentralized rural wastewater treatment. Unlike large-scale wetland systems that require digging pits and laying pipes, small-scale artificial wetlands are ground-integrated structures with a small footprint. (See also...) Figure 1 and Figure 2 The system includes a support trough 1, an inlet tank 2, a collection tank assembly 3, and an outlet tank 4. Each of these components is preferably a rectangular box. Typically, the top of the support trough 1 is open, and the bottom of the collection tank assembly 3 is open. The support trough 1 includes an inlet area 11, a collection area 12, and an outlet area 13, arranged sequentially and isolated from each other. The inlet tank 2, collection tank assembly 3, and outlet tank 4 are all detachably mounted on the top of the support trough 1. Typically, the bottom opening of the collection tank assembly 3 aligns with the top opening of the support trough 1. The inner cavity of the inlet tank 2 communicates with the inlet area 11, the inner cavity of the collection tank assembly 3 communicates with the collection area 12, and the inner cavity of the outlet tank 4 communicates with the outlet area 13. The inner cavity of the collection tank assembly 3 contains packing material 9. (Continue reading...) Figure 1 For reference Figure 3 The small modular constructed wetland device further includes an inlet assembly 5 and a collection assembly 6. The inlet assembly 5 includes a sewage pipe 51, a pump body 52, a transfer inlet pipe 53, and an outlet pipe network 54 connected in sequence. The inlet end of the sewage pipe 51 is used to connect to an external sewage collection pipe. The pump body 52 is located in the inlet area 11. The transfer inlet pipe 53 is located in the inner cavity of the inlet tank 2. The outlet pipe network 54 is located in the inner cavity of the collection tank assembly 3 and is situated above the packing material 9. (Continue reading...) Figure 1 For reference Figure 3The water collection assembly 6 includes a secondary connected and interconnected water collection network 61, a transfer outlet pipe 62, and a telescopic pipe 63. The water collection network 61 is located in the water collection area 12, the second transfer pipe is located in the outlet area 13, and the telescopic pipe 63 is located in the inner cavity of the outlet tank 4. When in use, the small modular artificial wetland device provided by this utility model extracts sewage from the wetland through the sewage pipe 51 and the pump body 52. ​​The pump body 52 then discharges the extracted sewage into the outlet network 54 along the transfer inlet pipe 53. After being discharged from the outlet network 54, the sewage flows downwards under gravity through the packing material 9 in the inner cavity of the water collection tank assembly 3. The sewage filtered by the packing material 9 is discharged from the bottom of the water collection tank assembly 3 and enters the water collection area 12. The filtered water entering the water collection area 12 re-enters the water collection network 61 and is then discharged into the outlet tank 4 through the transfer outlet pipe 62 and the telescopic pipe 63.

[0057] In the small modular artificial wetland device provided by this utility model, see [reference needed]. Figure 1 The water collection tank assembly 3 includes multiple water collection tanks that are detachably connected from top to bottom. The top and bottom of each water collection tank are open. A dividing mesh 32 is provided at the bottom of each water collection tank. Preferably, geotextile is provided on the dividing mesh 32. The dividing mesh 32 and geotextile are used to prevent filter material in the inner cavity of one water collection tank from falling into the inner cavity of the next water collection tank. However, the dividing mesh 32 and geotextile cannot prevent water from flowing from the inner cavity of one water collection tank to the inner cavity of the next. The packing material 9 includes various filter materials, and the filter material provided in the inner cavity of each water collection tank is different. In a specific embodiment, the water collection tank assembly 3 includes three water collection tanks. From top to bottom, each water collection tank has a filter layer packing, a purification layer packing, and another filter layer packing in its inner cavity. The packing material in the uppermost water collection tank has a plant layer on top. The filter layer packing initially filters large particulate impurities, and the purification layer packing ensures that the purified water is evenly distributed.

[0058] Optionally, see Figure 5The bottom sidewalls of the inlet tank 2 and the outlet tank 4 are each provided with magnetic protrusions 7, and the top sidewall of the support groove 1 is provided with multiple magnetic grooves 8. The corresponding magnetic protrusions 7 and magnetic grooves 8 are detachably connected. When installing the inlet tank 2 and the outlet tank 4 onto the top of the support groove 1, simply install the magnetic protrusions 7 at the bottom sidewalls of the inlet tank 2 and the outlet tank 4 into the corresponding magnetic grooves 8 at the top sidewall of the support groove 1. The magnetic protrusions 7 and magnetic grooves 8 are connected by magnetic force. Typically, the magnetic protrusions 7 and magnetic grooves 8 contain permanent magnets of opposite polarity so that they attract each other. In a preferred embodiment, the surface of the magnetic protrusions 7 is provided with a silicone waterproof strip. For illustration, the magnetic protrusions 7 and magnetic grooves 8 are preferably trapezoidal; the trapezoidal splicing method and the silicone waterproof strip can work together to achieve high sealing between the tanks.

[0059] Optionally, see Figure 5 The bottom of the side wall of the water collection tank is provided with a magnetic protrusion 7, and the top of the side wall of the water collection tank is provided with a magnetic groove 8. The corresponding magnetic protrusions 7 and magnetic grooves 8 between adjacent water collection tanks are detachably connected. The magnetic protrusion 7 of the bottommost water collection tank is detachably connected to the corresponding magnetic groove 8 on the top of the side wall of the support groove 1. Note that the number of water collection tanks is not limited, but the total height of the water collection tank group 3 should be consistent with that of the inlet tank 2 and the outlet tank 4.

[0060] Optionally, see Figure 3 The water outlet network 54 includes a main water outlet pipe 54.1 and multiple branch water outlet pipes 54.2 connected to the main water outlet pipe 54.1. The branch water outlet pipes 54.2 are located on both sides of the main water outlet pipe 54.1, and each branch water outlet pipe 54.2 has an outlet hole 54.2a for discharging sewage. The sewage flows downwards through the packing material 9 under gravity, and the packing material 9 filters impurities from the sewage. In a specific embodiment, the branch water outlet pipe 54.2 has a certain wall thickness, and the outlet hole 54.2a is located on the side wall of the branch water outlet pipe 54.2. The outlet hole 54.2a is conical, and its diameter increases from the inside to the outside. This conical hole design reduces impurity adhesion. Preferably, the inner wall of the outlet hole 54.2a is provided with a hydrophobic coating, which further blocks dirt.

[0061] Optionally, see Figure 4The water collection network 61 includes multiple main water collection pipes 61.1, each with a water collection hole 61.1a. Typically, the water collection hole 61.1a faces the bottom of the water collection area 12. Filtered wastewater flows from the bottommost water collection tank 31 into the water collection area 12 under gravity. Filtered water in the water collection area 12 enters the main water collection pipe 61.1 through the water collection hole 61.1a, and then flows through the main water collection pipe 61.1 into the telescopic pipe 63. The telescopic pipe 63 then discharges the filtered water into the outlet tank 4 for collection. Additionally, during continuous water intake, if the water level at the opening of the telescopic pipe 63 is lower than the water level in the packing material 9, water will overflow from the opening of the telescopic pipe 63 and enter the outlet tank 4.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
