Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically a modular artificial wetland experimental device. Background Technology

[0002] Constructed wetland wastewater treatment systems utilize the principles of species symbiosis and material recycling in ecosystems, as well as the principle of structural and functional coordination. While promoting the benign cycle of pollutants in wastewater, they fully leverage the productive potential of resources, prevent environmental re-pollution, and achieve optimal benefits in wastewater treatment and resource utilization, thus possessing high environmental, economic, and social benefits. After wastewater enters the wetland system, interactions occur between solid particles in the wastewater and matrix particles. Solid particles in the water flow directly encounter and are intercepted by the surface of the matrix particles. When particles migrate from the water to the surface of the matrix particles, they are adhered to the matrix particles under the influence of van der Waals forces, electrostatic forces, certain chemical bonds, and specific chemical adsorption forces. They may also be adsorbed and removed due to the bridging effect of flocculated particles. However, due to the biological and hydraulic complexity, inaccurate design and operating parameters often lead to improper design, resulting in effluent failing to meet design requirements or discharge standards. In some cases, constructed wetlands have even become sources of pollution.

[0003] To better protect the water quality of surface water sources and to achieve better treatment effects from constructed wetlands, experimental research on constructed wetlands is particularly important. However, based on current data, experimental devices for constructed wetlands still have many drawbacks. For example, most experimental devices require all the packing material to be emptied and replaced, or multiple parallel tests to be set up, making it impossible to replace only one type of packing material. Therefore, we need to propose a modular experimental device for constructed wetlands. Utility Model Content

[0004] The purpose of this invention is to provide a modular artificial wetland experimental device that allows for the replacement of the packing material in only one layer without affecting other layers, ensuring rapid and effective experimentation, making assembly and use more convenient, and enabling replacement according to experimental needs. This improves the ease of packing material replacement and enhances the practicality of the equipment, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular artificial wetland experimental device includes a packing box. The interior of the packing box is provided with multiple sets of insulating mesh partitions from top to bottom. The interior of the packing box is divided into multiple sets of packing cavities by the insulating mesh partitions. Each set of packing cavities is filled with wetland packing material. Multiple sets of arc-shaped sealing plates corresponding to the packing cavities are hinged to the packing box. Sealing strips for sealing are provided on the edges of the arc-shaped sealing plates. The sealing strips are pressed tightly against the edges of the packing box.

[0007] Preferably, the stuffing box is provided with multiple sets of buckles, and the arc-shaped sealing plate is provided with multiple sets of retaining rings corresponding to the buckles, the retaining rings being engaged in the buckles.

[0008] Preferably, the bottom of the stuffing box is connected to a water inlet pipe, and a water distribution trough is connected to the water inlet pipe.

[0009] Preferably, a water outlet pipe is provided at the top of the stuffing box.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In this modular artificial wetland experimental device, the packing box allows for the replacement of only one layer of packing material without affecting other layers, ensuring rapid and effective experimentation. This makes assembly and use more convenient, and the packing material can be replaced according to experimental needs, thus improving the ease of packing material replacement and enhancing the practicality of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution:

[0019] A modular artificial wetland experimental device includes a packing box 3. The interior of the packing box 3 is provided with multiple sets of isolation mesh partitions 7 from top to bottom. The interior of the packing box 3 is divided into multiple sets of packing cavities by the isolation mesh partitions 7. Each set of packing cavities is provided with wetland packing material 8. Multiple sets of arc-shaped sealing plates 4 corresponding to the packing cavities are hinged to the packing box 3. The edges of the arc-shaped sealing plates 4 are provided with sealing strips 9 for sealing. The sealing strips 9 are pressed tightly against the edges of the packing box 3.

[0020] It should be noted that the stuffing box 3 is made of PVC plastic pipes. The composition of the wetland packing 8 inside the stuffing box 3 may be the same or different, and can be replaced according to the purpose of the experiment.

[0021] The isolation mesh partition 7 serves to support the wetland filler 8 and divides the filler box 3 into multiple filler cavities. When it is necessary to replace the filler of a certain layer, the wetland filler 8 in the filler cavity can be taken out and replaced by opening the arc-shaped sealing plate 4.

[0022] In addition, the sealing strip 9 is made of PVC. The sealing strip 9 plays a role in sealing the contact edge between the arc-shaped sealing plate 4 and the stuffing box 3, thereby sealing the inside of the stuffing box 3 and preventing water from leaking out from the contact point between the arc-shaped sealing plate 4 and the stuffing box 3.

[0023] In an optional embodiment: the stuffing box 3 is provided with multiple sets of buckles 5, and the arc-shaped sealing plate 4 is provided with multiple sets of retaining rings 6 corresponding to the buckles 5, and the retaining rings 6 are engaged in the buckles 5.

[0024] It should be noted that the buckle 5 and the retaining ring 6 work together to open and close the arc-shaped sealing plate 4.

[0025] In an optional embodiment: the bottom of the packing box 3 is connected to a water inlet pipe 1, and a water distribution trough is connected to the water inlet pipe 1.

[0026] In an optional embodiment, a water outlet pipe 2 is provided at the top of the stuffing box 3.

[0027] In practical use, when replacing the wet packing 8 in the stuffing box 3, first open the arc-shaped sealing plate 4, take out the wet packing 8 in the stuffing cavity for replacement, close the arc-shaped sealing plate 4, and then fasten the retaining ring 6 with the buckle 5. At this time, the replacement of the wet packing 8 can be completed.
