technical field

The utility model belongs to the field of ecological restoration, in particular to an ecological restoration device for oxygenation and activation of water body.

Background technique

Due to the accumulation of various industrial and agricultural pollutants and eutrophic substances in water bodies, my country's water ecological environment has been polluted and destroyed to varying degrees.

my country is a water-scarce country, with per capita water resources less than 1/4 of the world average. What's more serious is that 90% of urban rivers in my country are polluted, more than 50% of rivers are seriously polluted, and 75% of lakes are artificially polluted and eutrophic, most of which have exceeded the critical point of ecological self-repair.

For example, in aquaculture water bodies, often due to the accumulation and fermentation of aquatic excrement and residual feed in the water body, the continuous accumulation of toxic substances such as ammonia nitrogen and nitrite in the water body will cause a large number of harmful algae to multiply and rob oxygen, causing aquatic products to cause disease and reduce production. Farmers want to maintain production. A large amount of antibiotics and toxic pesticides are often put into the water body, resulting in higher costs and food safety hazards. However, the existing aerators are often inefficient, consume a lot of energy and cannot reduce toxic substances, so the aquaculture water body reduces ammonia nitrogen and nitrite. Toxic substances and energy-saving and high-efficiency oxygenation have become the common aspirations of the majority of aquaculture farmers.

It can be seen that we are already facing a serious water ecological environment crisis. The ecological restoration of water bodies is imminent, and there is a long way to go.
