What are the problems in the treatment of high concentration ammonia nitrogen wastewater?

High-concentration ammonia-nitrogen wastewater has a certain inhibitory effect on microorganisms, but N is also an indispensable nutrient element for microbial growth.

Ammonia nitrogen wastewater treatment mainly includes the following methods:

If the ammonia nitrogen is too high, sodium hydroxide can be added to adjust the pH value of water to about 1 1, and ammonia nitrogen can be blown off by air through the ammonia nitrogen stripping tower, and the removal rate can reach about 80%.

Low-concentration ammonia nitrogen can be removed by denitrification wastewater treatment process, such as activated sludge process such as A/O, A/AO and SBR, and biofilm process of biological rotating disc in biological aerated filter. Of course, there are many professional problems involved. If you need to know more, I can send you some information.
