危险废物填埋设施的环境风险分析

识别了危险废物安全填埋场的风险源,建立了危险废物填埋处置环境风险评价方法,并将危险废物填埋的环境风险评价分为健康风险评价和系统安全性评价2个部分.对渗滤液污染地下水事故的风险评价方法进行了详细的讨论,分析总结了安全填埋场造成渗滤液泄露的原因,提出了其安全性分析方法.在此基础上,结合一组假定的填埋场的数据,进行了具体的风险评价和系统安全性分析.结果表明,所建立的事故情况下的健康风险分析方法和故障树安全性分析可以满足环境风险评价的需要.

The Environmental Risk Assessment of Hazardous Waste Landfill

The risk sources of the hazardous waste landfill were distinguished and the environmental risk assessment method of hazardous waste landfill established;the environmental risk assessment was divided into health risk assessment and system safety security assessment.The health risk assessment under the leachate pollution accident condition was discussed in details.The reasons of the leak of leachate were analyzed,and the method of the safety analysis of security landfill established.Based on a hypothesis case,the established methodology of health risk and the system safety of landfill are testified.The results confirmed that the established methodology of health risk and the system safety of landfill could satisfy the requirement of environmental risk assessment.
