Description

Technical Field

[0001] The utility model belongs to the technical field of artificial wetlands, and in particular relates to an artificial wetland filler unit based on metal biochar layer carbon functional filler. Background Art

[0002] Artificial wetlands are artificially constructed sewage treatment facilities that simulate the structure and function of natural wetlands. They are composed of aquatic plants, fillers, microorganisms and water bodies. The fillers serve as the base for microorganisms to attach and the carrier of aquatic plants. They use the triple synergy of physics, chemistry and biology in natural ecosystems to purify sewage. They have the characteristics of low construction cost, low energy consumption, good treatment effect, low operating cost, easy management, and beautification of the environment.

[0003] At present, artificial wetlands are generally permanent facilities, and their scale and land area requirements vary depending on the planning. This makes it difficult to accurately control the amount of filler. Too little filler may affect the structure and function of the artificial wetland, while too much filler will increase unnecessary construction costs and the risk of material waste. Secondly, considering that the filler of artificial wetlands is mainly filled below the wetland plants, the artificial wetland matrix is ​​prone to clogging. If the artificial wetland needs to be maintained, the filler needs to be dug out, cleaned, sorted, and re-landfilled. This method greatly increases the complexity of maintenance work and is time-consuming and labor-intensive, and cannot meet the use needs well. For this reason, we provide an artificial wetland filler unit based on metal biochar layer carbon functional filler. Utility Model Content

For the arrangement of multiple packing unit bodies 1, after one packing unit body 1 is set up, the angle of the L-shaped module 2 of another packing unit body 1 is attached to one side of the previous module unit for setting up. Similarly, the third packing unit body 1 is on the other side of the first packing unit body 1. The three packing unit bodies 1 are arranged in a convex shape, and are arranged in sequence according to this arrangement method, and then laid flat in the site of the artificial wetland to ensure the effective construction of the artificial wetland. In addition, for the packing unit bodies 1 arranged as a large whole, the L-shaped module 2 or the outer side of the module monomer 3 on the outside of the first shell 4 or the second shell 5 can be filled with medium soil The layer 81 may be used for leveling, or filling and leveling may not be performed, but vegetation may be planted on the medium soil layer 81 on its periphery to ensure aesthetics. As for the area of ​​the protruding first shell 4 and the second shell 5, it not only provides convenient conditions for planting trees, but also optimizes the spacing between adjacent trees to a certain extent, ensures the growth state of the trees, and guarantees the functionality of use. Furthermore, in order to effectively improve the rationality of the establishment of the filling unit body 1, a first shell 4 is provided above the corner of the L-shaped module 2, a second shell 5 is provided above one side of the module monomer 3, and a square-shaped fastening plate 6 is provided on the outside of the first shell 4 and the second shell 5, which serves to provide a certain degree of flattening of the filling unit body 1 arranged in a T shape.
