Most of the sewage treatment of synthetic ammonia uses the A/O method. The reason is that the sewage contains a small amount of nitrogen, and the COD in the sewage of synthetic ammonia is relatively low, so it is important to meet the nitrogen standards.

The wastewater is recycled centrally and sent to gasification for coal preparation and coal grinding.
