Ecological island and reef with sediment remediation function

Abstract

The invention relates to the technical field of ecological environmental protection, in particular to an ecological island and reef with a sediment remediation function. The ecological island and reefcomprises a remediation belt, wherein the remediation belt surrounds the island and reef, and the remediation belt comprises a planting layer, a stabilizing layer, a water film layer, a transition isolation layer and bottom sludge in sequence from top to bottom; the bottom sludge is used for providing nutrition for plants; the sludge is isolated from the planting layer by the transition isolationlayer; the water film layer is used for ensuring that a water body which enters the planting layer does not contain foul gas; a planting foundation is constructed for the planting layer by the stabilizing layer; and the planting layer is made of emergent aquatic plants and submerged plants, various fertilizers which are beneficial to plant growth are released by the sludge under the decompositioneffect of biological stuffing, deodorization is performed through a water film and the stabilizing layer, the peculiar smell of water on a water surface is reduced, finally, nitrogen, phosphorus andthe like are fixed under the decomposition effect of various plants, and environment pollution is prevented, so that the ecological island and reef is constructed.

Description

technical field [0001] The invention relates to the technical field of ecological environmental protection, in particular to ecological islands and reefs with built-in bottom mud restoration function. Background technique [0002] The so-called ecological islands and reefs are islands and reefs that can provide rest for wild animals and plants, for example: Shanxinsha Island in Shanxin Village, Qisha Town, Fangchenggang City ( figure 2 ), has attracted the attention of the outside world in the past two years. People pay more attention not only to the small island with a total area of ​​11.2 hectares, but also to the migratory birds that stop on the sand island. Shanxinsha Island is one of the important stopping points for bird migration. According to investigations, from September to March of the next year, 20,000 to 50,000 birds arrive at Shanxinsha Island, and there are more than 30 kinds of water birds, including many endangered species. In recent years, due to the surr...

Problems solved by technology

[0003] Some islands and reefs have produced a large amount of silt / sludge belt around the island due to excessive human activities, resulting in damage to the ecology of the islands and reefs. Therefore, there is an urgent need for a method that can restore the ecology of the islands and reefs and make the islands and reefs become ecological islands and reefs.
