Background technique

With the continuous expansion of the scope of human activities, surface water is gradually polluted to varying degrees, and the problem of eutrophication of lakes and reservoirs far away from urban areas has become prominent, while lakes and reservoirs in remote areas are mostly water supply sources or backup water sources, and water quality damage will affect the local area. In terms of water supply for residents, the status of lake and reservoir water supply in coastal areas is more prominent. Over-cultivation and fertilization, burning hills, felling trees, and cage aquaculture in these water basins have brought a large amount of nutrients, which has increased the risk of algal blooms. inconvenience. At this stage, eutrophication and pollution control of lake and reservoir water bodies have become important tasks for water resources protection. At present, the management of lake and reservoir water sources in my country is mainly limited to physical and biological means, such as dredging, changing water sources, mechanical collection of algae, and building water ecosystems. , many technologies are not suitable for use, and it is urgent to develop some technologies suitable for deep water bodies.

For deep water bodies, the physical environment is fundamentally different from that of shallow water bodies. The water level of deep water bodies fluctuates violently, and the difference between the front and back is as much as ten meters. Due to the depth of the reservoir, thermal stratification, which rarely occurs in shallow water bodies, often occurs. The thermal stratification of the water body produces an anaerobic zone at the bottom, which accelerates the release of nutrients in the sediment and brings certain hidden dangers. On the basis of fully understanding the characteristics of deep water bodies, reasonable treatment methods should be adopted to achieve better results. The deep water body is also an ecosystem, and the algal blooms caused by the increase of nutrients will destroy the structure of the ecosystem, simplify the system structure, and deteriorate the system stability. In the process of such water body governance, ecology should be taken as the core guiding ideology, and ecological theories should be applied to practice to construct the complex structure of the deep water ecosystem, improve the system's ability to resist shocks, and make the system self-adjust. Operation and management can achieve better ecological and economic benefits. However, due to the constraints of environmental conditions in deep water, it is impossible to build a deep water ecosystem like a shallow water ecosystem.
