Description

Technical Field

[0001] This utility model relates to the field of river ecological restoration technology, specifically to an ecological floating bed for river ecological restoration. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, a large amount of domestic sewage, industrial wastewater and agricultural non-point source pollutants are discharged into rivers, leading to a series of ecological problems such as eutrophication, reduced dissolved oxygen content and reduced aquatic biodiversity, which seriously affect the ecological function and landscape value of rivers.

[0003] Ecological restoration technology, with its advantages of low cost, ease of operation, and no secondary pollution, has become the mainstream direction for river management. Ecological floating beds, as one of the core pieces of equipment in ecological restoration technology, construct artificial ecosystems on the water surface. They utilize the roots of aquatic plants to absorb nutrients from the water, and rely on the microbial communities attached to the plant roots and the floating bed carrier to degrade organic pollutants. Simultaneously, they provide foraging and habitat space for fish and birds, achieving a synergistic effect of water purification and ecological restoration. However, existing ecological floating beds still have some shortcomings in practical applications. The plant planting devices on the floating beds are not securely fixed, plants easily fall off, and it is not conducive to plant replacement and maintenance. Furthermore, some ecological floating beds lack effective oxygenation devices, resulting in insufficient dissolved oxygen content in the water, which affects the activity of microorganisms and the degradation efficiency of pollutants. Therefore, there is an urgent need to design an ecological floating bed for river ecological restoration to solve the above problems. Utility Model Content
