Ammonia nitrogen blowing is a physicochemical method that converts ammonia nitrogen compounds in wastewater into gaseous ammonia gas, which is separated from the liquid phase. This process is usually carried out under alkaline conditions, taking advantage of the fact that the solubility of ammonia in water decreases with the increase in pH, and the ammonia is released from the wastewater by blowing air or pure oxygen into the wastewater.
Ammonia nitrogen blowing method has been widely used in the field of wastewater treatment, especially for the treatment of high-concentration ammonia nitrogen wastewater. Its main application scenarios include:
Chemical wastewater treatment: Many chemical production processes will produce high-concentration ammonia nitrogen wastewater, such as synthetic ammonia, urea, caprolactam, etc. In these scenarios, ammonia nitrogen blowing can effectively remove ammonia nitrogen from wastewater and reduce environmental pollution.
Municipal sewage treatment: The ammonia nitrogen content in urban sewage is high, and the ammonia nitrogen blowing method can effectively reduce the concentration of ammonia nitrogen in sewage and meet the discharge standards.
Landfill leachate treatment: The leachate produced by the landfill contains a high concentration of ammonia nitrogen, and the ammonia nitrogen blowing method can effectively remove the ammonia nitrogen in the leachate and reduce the pressure on the environment.
