How to treat high ammonia nitrogen in sewage

Adding sodium hydroxide to adjust the PH value of water to about 1 1, and blowing it off with air through ammonia nitrogen stripping tower, the removal rate can reach about 80%. It is impossible to reach the standard by this method alone, and subsequent treatment is needed. The remaining ammonia nitrogen can be removed by denitrification wastewater treatment process: for example, the biofilm method of biological turntable in biological aerated filter is used for treatment.

Treatment method of high ammonia nitrogen in sewage: add sodium hydroxide to adjust the PH value of water to about 1 1, and blow it off with air through ammonia nitrogen stripping tower, and the removal rate can reach about 80%. It's just that this method can't meet the standard and needs follow-up treatment. The remaining ammonia nitrogen can be removed by denitrification wastewater treatment process: for example, the biofilm method of biological turntable in biological aerated filter is used for treatment.
