摘要
文章采用污染评价法、健康风险评估法和地下水模拟污染预测法,共同探讨了某典型填埋场及周边地区的地下水氨氮污染特性及其对周边环境的影响。研究发现,填埋场中的地下水样品存在氨氮超标的问题,并且超标情况已扩散至填埋场边界以外的地区。通过污染评价法和健康风险评估法对调查目标污染程度和对人体健康的风险进行了评估,结果显示氨氮污染的风险水平较低且可接受。模拟预测表明,污染物在地下水中的迁移速度较慢,超过5年后的预测结果显示污染物的高浓度区域将逐渐减小。根据研究结果,在污染物迁移方向设置抽水井以控制污染扩散。
The study employed pollution assessment,health risk assessment,and groundwater simulation pollution prediction methods to investigate the characteristics of ammonia nitrogen pollution in a typical landfill and its impact on the surrounding environment.It is found that groundwater samples in the landfill site have exceeded the limit of ammonia nitrogen,and the exceedance has spread beyond the boundaries of the landfill site.The pollution level and health risks to human health were assessed using pollution assessment and health risk assessment methods.The results showed that the risk level of ammonia nitrogen pollution was low and acceptable.Simulation predictions indicated that the migration rate of pollutants in groundwater was slow,but the high concentration areas of pollutants were expected to gradually decrease after 5 years.Based on the research results,the installation of pumping wells in the migration direction of pollutants was recommended to control pollution dispersion.
