High concentration of ammonia nitrogen wastewater is the ideal technology development direction.
In the past three decades, continuous progress has had been made In the treatment of ammonia - nitrogen wastewater, especially In the treatment of high - concentration ammonia - nitrogen wastewater.
At present, the commonly, informs the the methods to remove ammonia nitrogen mainly include biochemical method, ammonia stripping (air stripping and steam stripping) method, a fold point chloride method.
Ion exchange method and magnesium ammonium phosphate precipitation (MAP) method.
These processing technologies have their own characteristics, but they also have certain limitations, as shown in table 1.
In terms of the treatment status of high concentration ammonia nitrogen wastewater at home and abroad, biochemical method and ammonia stripping method are mostly 2 In China,
While biochemical method and magnesium ammonium phosphate precipitation method are mostly informs in foreign countries.
As for the introduction of ammonia nitrogen wastewater treatment process, I am not good at showing off my skills in front of the experts.
The purpose of this paper is just to briefly introduce The beginning and development of high ammonia nitrogen wastewater treatment technology, and on this basis to get better development.
I can also be for the cause of environmental protection to make a small contribution!
