摘　　要：磷石膏的堆存不仅占用大量土地资源,磷石膏中残留的强酸、磷、氟、有机物等杂质可能随着雨水进入河流,污染土地和水源。由于公路建设点多、线长、面广的特点需要消耗大量原材料,将磷石膏作为道路材料使用,既能带来较好的经济效益,又能推动公路基础设施建设的可持续发展。将磷石膏作为路基材料,并对道路铺设后的周边土壤和地下水进行检测,施工路段土壤样品中监测指标均未超过《土壤环境质量标准建设用地土壤污染风险管控标准(试行)》(GB36600—2018)中第二类用地的标准,周围地下水样品污染物浓度均未超过《地下水质量标准》(GB/T14848—2017)Ⅲ类限值。The stockpiling of phosphogypsum not only occupies a large amount of land resources,but the strong acid,phosphorus,fluorine,organic matter and other impurities remaining in phosphogypsum may enter the river with rainwater,polluting the land and water sources.As the character-istics of highway construction with many points,long lines and wide surfaces require the consumption of a large number of raw materials,the use of phosphogypsum as a road material can bring better economic benefits as well as promote the sustainable development of highway infrastructure con-struction.In this paper,phosphogypsum is used as a roadbed material,and the surrounding soil and groundwater are tested after the road is paved,and none of the monitoring indicators in the soil samples of the construction section exceed the standard of the second class of land in the“Soil En-vironmental Quality Standards for Soil Pollution Risk Control Standards for Construction Land”(Trial)(GB36600—2018),and none of the pollu-tant concentrations in the surrounding groundwater samples exceed the“Groundwater Quality Standards”(GB/T14848—2017)Class III limit.
