The treatment methods for excessive nitrogen in river sewage include the following:
1. Biological method: Use biological treatment methods to reduce the nitrogen content in river water. For example, using activated sludge method, fixed biological treatment method, wetland treatment and other methods, nitrogen is converted into inorganic nitrogen substances through the action of microorganisms, thereby reducing the nitrogen content in the water body.
2. Physical method: Use physical methods to treat nitrogen in rivers, such as ultrafiltration, reverse osmosis and other membrane separation technologies, through the selective permeability of the membrane, the nitrogen substances in the water are separated, thereby reducing the nitrogen content.
3. Chemical method: By adding chemical reagents, such as copper sulfate, etc., chemical reactions occur with nitrogen in water to form water-insoluble substances, thereby achieving the removal of nitrogen. In addition, chemical methods also include oxidation method, reduction method, etc.
4. Gasification method: Utilize the nitrogen discharged from the gaseous conveyor belt in the river to convert the nitrogen substances in the water into nitrogen gas, thereby achieving the removal of nitrogen.
5. Comprehensive control measures: When treating excessive nitrogen in river sewage, a combination of multiple methods is used, such as combining biological methods, physical methods, chemical methods and gasification methods, and using their complementary advantages to achieve the best nitrogen removal effect.
