Description

TECHNICAL FIELD

[0001] The utility model relates to the field of river and lake management, especially to a river and lake bottom mud pollutant in-situ management equipment. BACKGROUND

[0002] With the improvement of human living standards, more attention will be paid to the protection of the natural environment, especially rivers and lakes.

[0003] In rivers and lakes, pollutants increase over time and are deposited in the bottom mud, which contains microorganisms that can decompose these pollutants. However, the growth of microorganisms requires supplemental oxygen, and a lack of oxygen content will result in a decrease in decomposition capacity, so an aeration component is needed. The aeration component typically uses a through pipe to aerate the bottom mud, but too much aeration will cause the bottom mud to be stirred up, and the bottom mud will flow away with the water, taking the microorganisms in the bottom mud with it, losing the in-situ management effect.
