四氟化硅

依据磷肥生产排出含氟废气中的四氟化硅和氟化氢含量的不同，以氟化铵和/或氨进行吸收，得到高浓度的氟硅酸铵溶液。

According to the different contents both silicon tetrafluoride and hydrogen fluoride in production of phosphate fertilizer , they are absorbed with ammonium fluoride and / or ammonia to obtain high concentration solution of ammonium fluosilicate , which is ammoniated and separated .

该磷肥生产车间的空气污染物主要为氟化物（氟化氢和四氟化硅），其次还有少量的氨和二氧化硫。

Fluorides are main pollutants in this factory , there is also ammonia and sulfur dioxide in small amounts .
