TECHNICAL FIELD

[0001] The utility model relates to waste liquid denitrification equipment technical field, concretely relates to a kind of kitchen waste liquid denitrification equipment. BACKGROUND

[0002] Nitrogen is essential for plant growth, but excessive nitrogen can lead to water eutrophication. When the nitrogen in kitchen waste liquid is directly discharged into natural water bodies without treatment, it can promote the rapid reproduction of algae and other aquatic plants. This overgrowth can consume dissolved oxygen in water, leading to water hypoxia, affecting the survival of aquatic organisms and disrupting the ecological balance of water bodies. In severe cases, it can even create so-called "dead zones", causing long-term negative impacts on aquatic ecosystems. In addition, excessive nitrogen can also affect the self-purification capacity of water bodies, leading to imbalances in water pH, and directly harming aquatic organisms. In particular, ammonia nitrogen is toxic to organisms in high pH environments, further threatening the survival of aquatic organisms.
