Abstract:

Taking the soil and groundwater restoration and treatment project of a hazardous waste landfill area as a practical case, the implementation effects of the pollution soil excavation and transportation cement kiln collaborative disposal, groundwater extraction water injection treatment process route were studied. The operational results indicate that the surrounding soil of this hazardous waste landfill area is mainly polluted by volatile phenols, arsenic, chromium, and antimony, and the surrounding groundwater is polluted by volatile phenols, fluoride, arsenic, and thallium; Volatile phenols are the main pollutants in the soil and groundwater of this hazardous waste landfill area; Groundwater pollution is closely related to soil pollution, but the characteristic pollutants in soil and groundwater are not completely consistent; The collaborative disposal process of excavating and transporting contaminated soil and cement kilns can quickly remove pollution sources, creating conditions for the remediation and treatment of groundwater; The groundwater extraction water injection treatment process can effectively improve groundwater quality, and the concentrations of volatile phenols, fluorides, arsenic, and thallium in groundwater can be restored to below standard limits in a short period of time.
