普通过磷酸钙清洁生产工艺的研究与应用

Study and application of cleaner production process of single superphosphate

通过实现氟硅酸循环利用 ,用含氟硅胶生产白炭黑 ,基本消除普钙生产中含氟污染物的排放 ,且有较好的经济效益。

This paper discusses the recycling of silicofluoric acid. Fluorine bearing silica gel is utilized to produce white carbon black. The emissions of fluorine bearing contaminants from single superphosphate production have been essentially reduced. Additionally, a lot of economic benefits has been brought.
