摘要
磷石膏是湿法生产磷酸的主要副产物,大量的磷石膏的堆存和排放不仅占用大量的土地,而且增加厂家的环保和管理压力,其中含有磷、氟、放射性元素和有机物等杂质的存在影响了对磷石膏资源的有效利用。文章旨在对磷石膏中的有害成分及其对环境的影响作阐述,以便寻求绿色生产路线、开发环境友好型产品。
Abslraet： Phosphorus gypsum is the main byproduct of the wet process production of phosphoric acid, storage and discharge a large number of phosphogypsum is not only occupy a lot of land, but also increase the manufacturer＇s environmental protection and management pressure, the impurities containing phosphorus, fluorine, radioactive elements and organic matter affects the effective utilization of phosphogypsum resource. The paper on the harmful components in phosphogypsum and its impact on the environment as described, in order to seek the green production line, the development of environmentally friendly products. Keywords： phosphorus gypsum; impurities; environmental impact
