Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an ecological floating island used for water purification. Background Art

[0002] In recent years, with the rapid development of my country's society and economy, the number of urban residents has increased dramatically, and the amount of sewage discharged has continued to increase, resulting in varying degrees of pollution in some urban lakes and rivers. In some areas, black and smelly water bodies have even appeared. The ecological environment of urban water bodies has been seriously affected and urgently needs to be treated. Plants have a high efficiency in removing eutrophic substances in water bodies and can significantly improve water quality. In view of the advantages of using plants for water purification, such as a wide range of applications, low purification costs, and taking into account landscape effects. In order to promote the ecological restoration of rivers and lakes and improve their landscape effects, measures such as the construction of ecological floating islands are usually taken to quickly increase the number and coverage of aquatic plants in the water area through ecological floating islands, promote the self-purification of water ecology, and reduce the degree of eutrophication of water bodies.

[0003] At present, when using aquatic plants to purify eutrophic water bodies, designers often only consider ornamental properties, and do not have sufficient theoretical basis for related issues such as the actual purification capacity of plants and the effect of combination and matching. Floating islands in the prior art are basically built of floating materials, which can be used to purify water quality and can also be used as landscape ornaments (such as a movable ecological floating island with water flow purification function disclosed in Chinese patent CN220703415U), but because the floating island is an integral structure, it is difficult to disassemble and assemble it after being put into actual use, so it is impossible to give play to the maximum purification effect. When the floating island area is too large, it is difficult for maintenance and management personnel to directly handle the plants located in the center of the floating island, so the area of ​​the floating island for practical application is limited.
