Multi-stage purification ecological wave-eliminating system for high stormy wave and low transparency water body area

Abstract

The invention relates to a multi-stage purification ecological wave-eliminating system for a high stormy wave and low transparency water body area, and particularly relates to the technical field of water environment ecological repairing. The system comprises an ecological submerged dike, the ecological submerged dike comprises a submerged dike body and benthonic organisms, wherein the benthonic organisms are put on the submerged dike body; the submerged dike comprises a first submerged dike and a plurality of second submerged dikes, and the first submerged dike is arranged at a preset distance from the shore side in the length direction along the shore side; the secondary dikes are connected with the first submerged dike at intervals and extended in the lake center direction; submerged plants are included, and the submerged plants are planted at the position between the shore side and the first submerged dike; floating leaved plants are further included, and the floating leaved plantsare planted at the lake gaps between the first submerged dike and the second submerged dikes. According to the system, the system has a wave-eliminating effect, and water bodies can be purified.

Description

technical field [0001] The invention relates to the technical field of ecological restoration of the water environment, in particular to a multi-stage purification ecological wave-elimination system for areas with high wind waves and low transparency water bodies. Background technique [0002] In recent years, the ecological degradation caused by lake eutrophication has led to the gradual evolution of the water body into turbid water algae, which has become one of the main problems in the water environment of rivers and lakes. [0003] At present, the existing lake management experience shows that the restoration of submerged plants and benthic organisms is an important link in the construction of clear-water grass-type lakes. However, in the ecological restoration of shallow lakes, strong wind and waves are likely to cause sediment resuspension, reduce water transparency, affect the improvement of water quality and the stability of the shore zone of the lake, and at the sam...

AI Technical Summary

Problems solved by technology

[0004] However, during the process of invention and creation, the inventor found that the existing technology has the following defects: although the physical dam has good wave dissipation effect, long service life and stable structure, the investment of the physical dam is relatively large, the construction is relatively complicated, and the impact on the hydrodynamic force of the lake is relatively large. The impact and landscape are relatively large, and the integrity of the water surface cannot be maintained. At the same time, it also affects the exchange of materials and capabilities in the lakeside area. The base at the bottom of the row-type rigid wave-dissipating piles is easily hollowed out by the water flow in a short period of time, causing the wave-dissipating row piles to collapse at the root, and the maintenance cost is high; although the floating bamboo rafts have the characteristics of convenient material acquisition and low cost, they can The planting of emergent plants forms a protective belt that is both beautiful and has a good wave dissipation effect, but the wave dissipation body itself does not have the function of purifying water quality and improving benthic biodiversity, and the maintenance cost in the later period is relatively high
