基于FEFLOW的油库污染物渗漏模拟研究

Contaminant leakage simulation study of oil depot based on FEFLOW

针对油库正常运行中可能出现的渗漏污染问题,以云南省某地下油库为研究对象,利用FEFLOW软件,采用数值分析方法,对研究区内典型污染物在不同工况下的污染物迁移进行模拟。计算结果表明,在正常工况下,污染物的影响范围随时间增加而增大,但是影响范围未超出厂区,不会对周边环境造成污染;在油库防渗层失效的非正常工况下,污染物的扩散速度快速增加,污染物的影响范围远远大于正常工况下,会对周边环境造成一定污染。建议设置地下水监测点进行定期检测,预防突然状况造成的污染物渗漏。研究成果为油库运行中可能出现的污染渗漏和相关污染防治提供了一定的科学依据。

Aiming at the possible leakage pollution problem in the normal operation of oil depot,taking an underground oil depot in Yunnan Province as the research object,the pollutant migration of typical pollutants in the study area under different working conditions is simulated by using FEFLOW software and numerical analysis method.The calculation results show that under normal working conditions,the influence range of pollutants increases with time,but the influence range does not exceed the factory area and will not pollute the surrounding environment.Under the abnormal working condition of oil depot impervious layer failure,the diffusion rate of pollutants increases rapidly,and the influence range of pollutants is much larger than that under normal working condition,which will cause certain pollution to the surrounding environment.It is recommended to set up groundwater monitoring points for regular detection to prevent pollutant leakage caused by sudden conditions.The research results provide a certain scientific basis for the possible pollution leakage and related pollution prevention and control in the operation of oil depot.
