摘要:
磷石膏(PG)是湿法磷酸生产过程中产生的一种工业固体废弃物。为深入了解PG的特性及其对环境的影响,选取湖北兴发化工集团股份有限公司和湖北鄂中生态工程股份有限公司湿法磷酸工艺中产生的PG及堆存1 a的PG、堆场附近(距堆场距离不同)的土壤样品为分析对象,研究不同来源PG的形貌结构、化学成分含量和PG对周边土壤的影响。采用扫描电子显微镜、能量色散光谱、X射线衍射仪和激光粒度仪对PG的微观形貌和物相组成进行了分析,并且测定了PG中各化学成分的含量以及堆场周边土壤中磷的含量。研究结果表明,PG主要含有磷、氟和有机物等杂质。此外,不同产地的PG的形貌结构和组成成分含量存在微小差异。堆存1 a的PG的ω(P2O5)和ω(可溶性磷)分别为1.51%和0.47%,新产生的PG的ω(P2O5)和ω(可溶性磷)分别为8.52%和5.29%,堆存后的PG中的磷含量有所减少,磷可能迁移至周边环境;距离堆场0、100、200 m的土壤中总磷含量分别为1 060.0、140.0、83.5 mg/kg,表明距离堆存场地越近,土壤中的总磷含量越高。
Abstract:
Phosphogypsum (PG) is an industrial solid waste generated during the wet-process phosphoric acid production. In order to further investigate the characteristics of PG and its impact on the environment, PG produced in the wet phosphoric acid production process from Hubei Xingfa Chemical Group Co., Ltd., and Hubei Ezhong Ecological Engineering Co., Ltd., and PG stockpiled for one year and soil samples near the storage yard (with different distances from the PG storage yard) were selected as the analytical targets. The morphology and the contents of chemical compositions of PG from different sources, as well as the impacts of PG on the surrounding soil were investigated. The morphology and phase composition of PG were analyzed by scanning electron microscopy,energy dispersive spectrometer, X-ray diffractometer and laser particle size analyzer, and the content of each chemical composition in PG and the content of phosphorus in the soil around the PG stockyard were determined. The results indicated that PG primarily contains impurities including phosphorus, fluorine and organic compounds, and there are minor differences in morphology and the contents of chemical compositions of PG from different origins. The ω(P2O5) and ω(soluble phosphorus) of PG stored for 1 year are 1.51% and 0.47%, respectively, while the ω(P2O5) and ω(soluble phosphorus) of freshly produced PG are 8.52% and 5.29%, respectively, indicating that the phosphorus content of PG after storage has decreased, which may have migrated to the surrounding environment. The total phosphorus content in the soil at distances of 0,100,and 200 m from the storage site were 1 060.0, 140.0 and 83.5 mg/kg, respectively, indicating that the closer to the storage site, the higher the content of total phosphorus in soil.
