How to treat wastewater containing ammonia nitrogen?

Ammonia leaked from the tubes of the 5-degree chilled water ammonia evaporator in our company, resulting in ammonia contamination in the brine. Now, this ammonia-containing wastewater has entered the sewage and rainwater systems. I would like to ask everyone for advice on how to deal with this situation # hcbbs
Is there a simpler and more practical method?
A concentration is needed; otherwise, specific advice cannot be given. If the concentration is low, considering the use of sodium hypochlorite for oxidation treatment is advisable.
Discharge it and then add fresh water.
The ammonia nitrogen content is between 200–500 mg/l
Chlorine is introduced into the ammonia-containing saline to ensure a certain level of free chlorine in it, which allows the ammonia nitrogen concentration to be reduced to a few ppm. The ammonia gas and free chlorine generated are then removed using air; if there is still some free chlorine left, a small amount of sodium sulfite is added. The principle is that chlorine reacts with ammonia to produce nitrogen and hydrochloric acid.

What things are there? For example, in terms of salt content, the biochemical method should be relatively inexpensive; an aerated biological filter could be considered
