Full-process all-season treatment process for controlling lake flooding of lake water body

The invention relates to a full-process all-season treatment process for controlling lake flooding of a lake water body. The treatment process comprises the following steps: 1, arranging a wind-wave-resistant enclosure in a water area where lake flooding easily occurs, and intercepting cyanobacterial bloom; 2, sucking floating algae slurry by adopting a mechanical blue algae salvage ship; 3, conveying the floating algae slurry to a composite algae-water separation ship through an overwater floating pipeline; 4, adding two water treatment agents, namely a water treatment agent I and a water treatment agent II, into the floating algae slurry on the composite algae-water separation ship, mechanically dehydrating the flocculated floating algae slurry to obtain wet algae mud with the water content of less than or equal to 90 percent, treating tail water through air flotation equipment, and discharging the tail water after reaching the standard; 5, conveying the algae mud to an algae mud transport ship through a sp
