Description

TECHNICAL FIELD

[0001] The utility model relates to a duckweed cleaning technical field, concretely is a kind of agitating device for preventing duckweed accumulation. BACKGROUND

[0002] The growth of duckweed requires abundant nutrients, especially nitrogen and phosphorus. If the nitrogen and phosphorus content in the sewage of the sewage treatment plant is high, these nutrients will promote the reproduction of duckweed. The increase of organic matter can also provide the nutrients required by duckweed.

[0003] In the case of poor water flow or water surface stillness, duckweed is more likely to accumulate on the water surface. Flowing water helps to reduce the accumulation of duckweed. Duckweed hinders the gas exchange of air and water body, affects the reoxygenation of water body, causes the dissolved oxygen content in water to decrease, and threatens the survival of aquatic organisms, which is often seen in the secondary sedimentation system with relatively slow flow rate.
