Abstract

The invention discloses a water quality in-situ improving device capable of automatically switching between full-layer mixing and isothermal layer aeration. The device comprises a guiding device, an upper rising cylinder, an intermediate rising cylinder and a lower rising cylinder which are connected sequentially from top to bottom, wherein a first water-sealed bin used for supplying buoyancy is formed in the top of the guiding device; a plurality of water-sealed bins used for supplying buoyancy are formed in the periphery of the intermediate rising cylinder; a secondary water-sealed bin used for supplying buoyancy is formed in the periphery of the top of the lower rising cylinder, and a gas storage chamber consisting of a first air chamber, a second air chamber and a third air chamber is formed in the periphery of the middle part of the lower rising cylinder; a water-seal plate is arranged between the second air chamber and the third air chamber, and a plurality of through holes are formed in the periphery of one end, close to the second water-seal bin, of the water-seal plate; an aeration chamber is formed in the periphery of the lower part of the lower rising cylinder; the opening end of an air release pipe is arranged at the opening of the lower end of the aeration chamber, and the lower end of the lower rising cylinder is connected with an anchor pier. The water-quality in-situ improving device can be used for realizing automatic switching between full-layer mixing and isothermal layer aeration based on running condition control.

Description

【Technical field】 [0001] The invention belongs to the field of water quality pollution control of lakes and reservoirs, and in particular relates to an in-situ water quality improvement device for automatic switching between full-layer mixing and isothermal-layer aeration. 【Background technique】 [0002] The traditional multi-functional water pumping aerator has the functions of full-layer mixing and isothermal layer oxygenation at the same time. It can use the circulating water flow formed by periodic air bomb release to mix the upper and lower water bodies of stratified lakes and reservoirs, and can supplement oxygen to the isothermal layer water body. Due to the low mobility of lake water and reservoir water, many organic matter, nitrogen, phosphorus and other nutrients are deposited and accumulated at the bottom of lakes and reservoirs. These substances provide potential sufficient nutrients for algae and other phytoplankton; The algae can stay in the surface water stabl...
