摘要
突发性污染地下水泄漏对周围水环境的影响具有重要研究意义。借鉴时序蒙特卡罗(SMC)方法来模拟污染源运行状态,并结合相应的河流水质模型,对污染地下水泄漏后造成的河流水质超标风险概率进行研究;利用健康风险评价模型,对污染物泄漏时水环境造成的人体健康风险进行评价。以某铬盐场为例验证该方法的稳定性和实用性。结果表明,该场地受污染的地下水对人体健康产生的危害程度为中级,其超标风险概率随模拟时间的增加而趋于稳定。
Effect of sudden leakage from polluted groundwater on the surrounding surface water has important significance. In this study,operating status of pollutant source was simulated by sequential monte carlo( SMC). Combined with the surface water quality model,the probability of simulated river water quality exceeding the corresponding water quality standard was calculated. Moreover,the health risk assessment model was used to evaluate the human health risk that caused by polluted surface water. A chromium salt field was taken as an example to verify the stability and practicability of this method. The results showed that the hazard degree of human health caused by polluted surface water was moderate. The probability of the risk increased with simulation time and tended to be stable when the simulated time was longer.
