Description

Technical Field

[0001] The invention relates to an extendable structural device and method for promoting water mixing and lower layer algae removal, belonging to the technical field of ecological purification. Background Art

[0002] In recent years, eutrophication of water bodies has become a serious environmental problem faced by China, especially in static water bodies such as lakes and reservoirs. With the rapid economic development and the intensification of agricultural production, a large amount of nutrients containing nitrogen and phosphorus enter the water bodies through agricultural runoff, domestic sewage and industrial wastewater, leading to the overgrowth of algae and other aquatic plants and the formation of algal blooms. Eutrophication not only affects the ecological balance of water bodies, but also threatens the safety of drinking water. In severe cases, it can lead to large-scale fish deaths and damage fishery resources.

[0003] In order to reduce the harm caused by eutrophication of water bodies and maintain the healthy and sustainable development of the water ecological environment, a large amount of research has been carried out in China and a variety of algae reduction technologies have been adopted. At present, the algae reduction technology mainly uses physical, chemical or biological means to control or reduce the number of algae in the water body. The physical method improves the water condition by mechanically salvaging algae and aeration; the chemical method uses flocculants and algaecides to control the growth of algae; the biological method naturally inhibits algae by introducing filter-feeding fish and repairing wetland ecosystems. At present, there are still shortcomings in the above methods. The existing physical technology still requires a lot of manpower and material resources and is costly. Chemical technology will cause secondary pollution to the environment. Biological technology may destroy the original ecological structure and the effect is slow. Summary of the invention
