Composite unit for restoration of landscape water body

Abstract

The invention discloses a composite unit for restoration of a landscape water body. The composite unit at least comprises a water quality regulating zone, a filtration and sewage interception zone, an emergent aquatic plant arranging zone, a waterfall reoxygenation zone, an artificial floating island arranging zone, a base and a connecting pipe, wherein the water quality regulating zone is fixed on the filtration and sewage interception zone in an embedded mode, the middle of the emergent aquatic plant arranging zone is provided with a diversion table, the upper part of the diversion table is used for supporting the filtration and sewage interception zone, the filtration and sewage interception zone, the diversion table, the waterfall reoxygenation zone, the artificial floating island arranging zone and the base are respectively provided with a first center hole, a second center hole, a third center hole, a fourth center hole and a fifth center hole, and the connecting pipe passes through the first center hole, the second center hole, the third center hole, the fourth center hole and the fifth center hole to allow the filtration and sewage interception zone, the emergent aquatic plant arranging zone, the waterfall reoxygenation zone, the artificial floating island arranging zone and the base to be fixedly connected from top to bottom. The composite unit has the advantages of high water purification efficiency, no generation of secondary pollution, simple and convenient construction and maintenance, low investment cost and a small occupied water area.

Description

technical field [0001] The invention belongs to the technical field of water environment restoration, and in particular relates to a combined device for landscape water body restoration. Background technique [0002] In recent years, with the continuous development of society and the continuous improvement of people's living conditions, landscape water has been integrated into people's lives, and the construction of waterscape-themed communities, parks, towns, etc. is in a stage of rapid development. At the same time, due to pollution, the water quality of some landscape water bodies has deteriorated, the lake water has turned black and smelly, and the problems of eutrophication of water bodies are becoming increasingly serious. Obviously, landscape water body restoration has become a hot spot in the field of water environment restoration. [0003] At present, landscape water body restoration technologies mainly include aeration and oxygen enhancement, phytoremediation belt...

AI Technical Summary

Problems solved by technology

Due to the disadvantages of low purification efficiency, high investment, and poor flexibility, the first four technologies limit their large-scale promotion and use

The existing artificial floating island technology has the advantages of low investment, high flexibility, and good purification effect on nitrogen and phosphorus in landscape water, but its disadvantages are that it occupies a large water area and affects flood control and drainage, especially in winter. Plant growth is slow There is almost no water purification effect, and the maintenance project is large and costly. If the dead plants are not salvaged in time, they will easily settle and rot at the bottom of the water, causing secondary pollution.
