摘要
为识别反映地下水质量的优先控制污染物,基于污染物危害性评价体系,结合某炼厂污染物的检出率、检出浓度和超标倍数,建立了石油炼化企业地下水中优先控制污染物识别方法;采用该方法对石油炼制厂地下水污染物进行了筛选研究。结果表明,石油炼化行业地下水中优先控制污染物清单包括苯、甲苯、乙苯、二甲苯、石油烃、苯酚、挥发性酚类、砷、铅和锰等10种5类污染物。研究结果与实验监测结果具有一致性,石油炼化厂地下水污染应优先控制清单中污染物,尤其是苯系物和石油烃。
In order to recognize the priority pollutants reflecting the groundwater quality,one new method for screen the characteristic pollutants in groundwater of the petroleum refining enterprise was established by combining comprehensive score method for pollutant hazard assessment and detection rate,concentration and standard exceeding rate of groundwater pollutant components.Researching on recognition the pollutants in groundwater of the petroleum refining enterprise by this method.The result showed that priority pollutants list included 10 kinds of pollutants in 5 categories:benzene,toluene,ethylbenzene,xylene,total petroleum hydrocarbons,arsenic,anthracene and benzo(a)pyrene.The result of recognition in this method was consistent with the experimental monitoring result.Consequently,the 15 kinds compounds should be controlled firstly in the oil petroleum refining enterprise,especially benzene series and petroleum hydrocarbons.
