Environmental risks and countermeasures analysis of phosphogypsum comprehensive utilization under green and low-carbon background
Phosphogypsum is a kind of solid waste generated in the process of phosphochemical production.Its composition is complex and difficult to handle.Long-term storage not only occupies a large amount of land resources,but also poses a serious threat to ecological security of the region.With the increasing concern of phosphogypsum pollution and the announcement of relevant policy documents,the comprehensive utilization level of phosphogypsum has been improved year by year,but it has also brought new environmental risks.Based on the current situation of comprehensive utilization of phosphogypsum,the main sources of environmental risks in the process of comprehensive utilization were analyzed,and the corresponding environmental risk factors and risk receptors were identified.The environmental risk analysis model of phosphogypsum comprehensive utilization based on social network analysis was constructed,and the environmental risk factors,environmental risk receptors and their interactions were analyzed.Finally,the key environmental risk network nodes were identified,and environmental risk curtailment suggestions had been proposed according to the current requirements of green and low-carbon development.
