Description

Technical Field

[0001] The utility model relates to the field of water environment management, in particular to an assembled floating subsurface wetland. Background Art

[0002] As a way of water environment management, floating wetlands not only enrich the water surface landscape, but also purify water pollution and improve water quality. Traditional floating wetlands are in the form of splicing floating basins, net bags or fiber carriers. In floating wetlands made of splicing floating basins, plants are planted in the floating basins, and the roots cannot fully contact the water body; net bag-type floating wetlands have poor impact resistance due to insufficient structural support; CN116081823A discloses a composite fiber floating wetland system, but the floating wetland carrier of the composite fiber carrier is an integrated composite fiber material, and microorganisms can only attach to the surface of the carrier, with weak purification efficiency and no effect on phosphorus. Traditional floating wetlands are relatively single in plant selection, and only aquatic plants can be used. The floating material has no purification effect on the water body, and with the increase in the length of use, the aging of the floating body and the withering of aquatic plants in winter will cause secondary pollution to the water body. The purification function of traditional floating wetlands mainly relies on the purifying effect of the roots of emergent plants on water bodies. However, due to the periodicity of plant growth and the natural influence of seasons, the purification capacity is greatly reduced in winter. At the same time, the weakened photosynthesis and the shading effect of the matrix can easily cause the dissolved oxygen content in the water to decrease, prompting the explosive growth of anaerobic microorganisms and an increase in harmful pollutants in the water, which in turn leads to deterioration of water quality.

[0003] Therefore, some non-traditional floating wetlands have emerged, which use assembled frames, filled with purification fillers, and combined with aquatic, terrestrial, and wetland plants to purify water. However, the on-site assembly of such wetland frames is time-consuming and labor-intensive, and because they are not integrally formed, they have poor impact resistance and are easily washed away when dealing with water bodies with strong winds and waves. The assembled frames are difficult to raise and lower, and the fillers in the floating wetlands have increased water absorption due to long-term immersion in water, resulting in reduced buoyancy and causing the wetlands to sink.
