Description

Technical Field

[0001] The utility model relates to the technical field of water source purification, in particular to a complete device for capturing bottom mud and removing nitrogen and phosphorus from farmland drainage ditches. Background Art

[0002] The nutrients such as nitrogen and phosphorus accumulated in the bottom mud of farmland drainage ditches are harmful to the environment and cause eutrophication of water quality: nitrogen and phosphorus are the main nutrients that promote the growth of algae in water bodies. When farmland drainage carries excessive nitrogen and phosphorus into water bodies, it will lead to eutrophication of water bodies. Algae will multiply in large numbers and form "water blooms", which consume oxygen in the water and cause water hypoxia. In severe cases, it can cause large-scale deaths of fish and other aquatic organisms, destroying the balance of the aquatic ecosystem. The structure of the ecosystem will change. Eutrophication will not only affect the survival of aquatic animals, but may also lead to changes in the structure of aquatic plant communities. Some species that are resistant to low oxygen may become dominant species, while species with high water quality requirements may decrease or disappear.
