摘  要:
The transformation situation of wastewater recycling utilization from SA production by pyrite,and the rectification measures in the transformation are introduced.The wastewater is neutralized treatment by the waste aqueous ammonia from the nearby synthetic ammonia plant,to solve not only the company's wastewater treatment problem,but also the nearby synthetic ammonia plant's waste ammonia efflux problem.After transformation,the utilization rate of water recycling is more than 95%.
