  • How is ammonia nitrogen used in wastewater treatment?
  • Currently, during treatment of polluted water, the wastewater with high-concentration ammonia nitrogen is usually converted via physical or chemical methods to wastewater with low-concentration ammonia nitrogen before subsequent treatment.
  • What is microbial treatment of ammonia nitrogen?
  • Microbial treatment of ammonia nitrogen means that ammonia nitrogen in water can finally generate nitrogen through a series of reactions such as nitrification and denitrification under the action of various microorganisms. Microbial removal of ammonia nitrogen requires two stages.
  • What is biological nitrogen removal?
  • The biological nitrogen removal (BNR) process is a cheap and the most widely practiced approach for nitrogen control in wastewater treatment. For many years, the traditional biological method for nitrogen removal from wastewater has been the combination of nitrification and denitrification processes.
  • What is bacterial and photocatalytic ammonia nitrogen treatment?
  • The typical mechanism of bacterial and photocatalytic ammonia nitrogen treatment (NOB refers to nitrite oxidizing bacteria; AOB refers to ammonia oxidizing bacteria; AOA refers to ammonia oxidizing archaea) ( Du et al., 2019; Feng et al., 2021 ). 2. Microbial ammonia nitrogen treatment 2.1.
