Ecological floating bed system for water restoration of lakes under powerful stormy wave condition

Abstract

The invention discloses an ecological floating bed system for water restoration of lakes under a powerful stormy wave condition. According to functional partitioning, the ecological floating bed system comprises a windproof filtering bed, an algae guiding area and an ecological restoration bed. Under the condition of powerful stormy waves with blue-green algae, firstly, wave dissipation and wind prevention are performed through the windproof filtering bed, and coarse-grain-size pollutants in water are filtered below a floating bed; secondly, by virtue of an included angle between the windproof filtering bed and the wind direction, the intercepted algae and coarse-grain-size pollutants are guided to enter enclosures to be collected and fished; and finally, on the basis of pre-processing, the purification function of the ecological restoration bed on water is guaranteed. The built ecological floating bed system is strong in environmental adaptability, wide in application range and definite in system hierarchy, is particularly suitable for water pollution restoration of seriously eutrophic lakes in China, and therefore, is of great significance.

Description

technical field [0001] The invention relates to an ecological floating bed system used for lake water restoration under strong wind and waves, and belongs to the technical field of environmental ecological restoration. Background technique [0002] In the past 20 years, the pollution of lake water environment has become more and more prominent, and the eutrophication disaster of lakes has become an important factor restricting the further sustainable development of society and national economy. Some river waters such as the Han River, Pearl River, and Dongting Lake are facing the threat of eutrophication. Water blooms in some waters of Dianchi Lake last up to 10 months every year, and some waters of Chaohu Lake and Taihu Lake are also in a state of water blooms for a long time. Eutrophication of water bodies and algal bloom hazards not only cause water dysfunction and affect aquaculture and landscape tourism, but more importantly, algal toxins and their derivatives produced...
