【摘要】The effects, problems and causes of controlling Chaohu Lake and eliminating blue-green algae outbreak were comprehensively analyzed, and the objectives of controlling Chaohu Lake and cor-responding technical integration measures were put forward. Control effect: Control the external source and remove the internal source, improve the water quality of the river into the lake, improve the water quality of Chaohu Lake from inferior class V to class V, and reduce the accumulation of cyanobacteria on the water surface. The existing problems are as follows: The control of external and internal sources is not enough; the current water quality of Chaohu Lake is still far from the target of class III; the outbreak of cyanobacteria is still serious. Recommended target: To eliminate cyan bacteria outbreak in different water areas from 2025 to 2035. Safeguard measures: Further promote the system of river head and Lake Head, integrate the governance of Chaohu into the Yangtze River protection strategy, increase scientific research efforts, and revise the governance plan of Chaohu. Innovative ideas of Chaohu Lake treatment technology integration are: 1) eutrophication treatment: control source and intercept pollution, actively treat non-point sources such as sewage plant, industrial, domestic, large-scale livestock and poultry breeding point sources and agricultural and rural areas, with the focus on building sufficient sewage treatment capacity and improving the treatment standard of sewage plant; reduce endogenous, mainly remove cyanobacteria and lake bottom sludge. 2) Algae removal: Comprehensive salvage and removal of cyanobacteria on water surface, water body and bottom. 3) Wetland restoration: Large scale restoration of coastal wetland, artificial restoration to promote natural restoration, so that the vegetation coverage of Chaohu Lake from 5% to the original 25%~30%. Conclusion: It is necessary to eliminate the outbreak of cyanobacteria in Chaohu Lake by giving full play to the institutional advantages of concentrating on major events with Chinese characteristics, establishing goals and integrating technological innovation.
