Description
Technical Field
[0001] This utility model relates to the field of constructed wetland technology, specifically a modular artificial wetland filler device that is easy to maintain and replace. Background Technology
[0002] In recent years, with the acceleration of urbanization and industrial development, water pollution has become increasingly serious, posing a severe threat to the ecological environment and human health. Constructed wetlands, as an efficient, economical and eco-friendly wastewater treatment technology, have been widely used in the treatment of domestic sewage, industrial wastewater and agricultural non-point source pollution.
[0003] The core of constructed wetlands lies in the filler material inside. This filler material not only provides a carrier for the attachment and growth of microorganisms, but it can also remove pollutants from the water through physical filtration, chemical adsorption, and ion exchange. Traditional constructed wetland filler materials usually use single or mixed materials such as gravel, sand, zeolite, and limestone, which are directly laid in the wetland bed. However, when the filler material needs to be replaced due to adsorption saturation or blockage, the wetland system must be shut down and large-scale excavation and reinstallation must be carried out. This is not only cumbersome and labor-intensive, but it also damages the established ecosystem of the wetland, resulting in a significant drop in treatment efficiency during the recovery period. Moreover, single-type filler materials often only have a good removal effect on one or a few types of pollutants, making it difficult to deal with complex wastewater. Utility Model Content

The flow guide seat 29 is inclined, and a discharge port 210 communicating with the inside of the shell 1 is opened on one side of the separation box 21. Furthermore, the feeding assembly includes a feeding box 25 installed on the top of the housing 1, an inclined seat 211 installed inside the feeding box 25, one end of the inclined seat 211 corresponding to the top of the separation box 21, and a splash guard 26 that cooperates with the inclined seat 211 is fixedly installed on one side of the feeding box 25.

The filter screen synchronous belt 23 inside the separation box 21 is driven by the drive motor 27 of the drive assembly, which drives the synchronous wheel 28 to rotate, thereby causing the filter screen synchronous belt 23 to rotate. When the wastewater passes through the filter screen synchronous belt 23, the water flows down through the filter holes, while the sludge is trapped on the filter screen synchronous belt 23. As the filter screen synchronous belt 23 rotates, the trapped sludge is carried to the top of the collection box 22 of the collection assembly. Under the action of the scraper 24, the sludge is removed. The water is scraped into the collection box 22. The inclined guide seat 29 at the bottom of the separation box 21 allows the separated water to flow into the shell 1 through the discharge port 210.

The multiple sets of sliding grooves 5 also facilitate the installation and disassembly of these components.
