| 摘 要： | 以苏南某焦化厂为研究对象,在对污染区域初步识别的基础上,采集了0～4.5 m深的22个土壤样品和2个地下水样品,利用GC/MS等检测了多环芳烃类、总石油烃、苯系物、重金属,总氰化物、挥发酚、硫化物的含量,并研究了其在不同功能区土壤和地下水中的特征分布。结果表明:(1)该焦化场土壤和地下水受到了不同程度的污染,其中炼焦炉周边、焦油和洗油储罐区、焦油和粗苯加工车间是污染最严重的区域;(2)土壤中主要超标污染物是多环芳烃、总氰化物、总石油烃、单环芳香烃、二苯呋喃、苯胺、硫化物、挥发酚和一些苯酚类化合物;(3)地下水重点污染区域粗苯车间受到总氰化物、苯胺、苯酚类、萘、总石油烃、单环芳香烃的严重污染,污水处理站区域地下水主要污染物包括总氰化物、萘、总石油烃、苯。

| Abstract: | On the basis of preliminary identification of contaminated zone of a coking plant in the south of Jiangsu Province,the sampling plan was decided,and 22 soil and 2 groundwater samples were collected.The concentrations of polycyclic aromatic hydrocarbons(PAHs),total petroleum hydrocarbons(TPH),volatile organic compounds,monocyclic aromatic hydrocarbons(MAH),total cyanide,heavy metals,sulphide,phenols and so on were analyzed by a gas chromatography equipped with mass spectrometry(GC-MS)and other instruments,and their characteristic distributions in the soils and groundwater of different functional areas were discussed.Results showed that:(1)Soils and groundwater around the coking plant were contaminated,especially the coke oven,tank area of coal tar and cleaning oil,the coal tar and crude benzene processing workshop;(2)The main pollutants in the soils were PAHs,total cyanide,TPH,MAH,dibenzofuran,aniline,sulfide,phenols,and in the no-disturbed soil samples PAHs were accumulated in the topsoil and rapidly decreased with depth;(3)The main pollutants in the groundwater of crude benzene processing workshop were total cyanide,aniline,phenols,naphthalene,TPH,MAH.The main pollutants in the groundwater of sewage treatment station were total cyanide,naphthalene,TPH,benzene.The groundwater of crude benzene processing workshop was contaminated more serious than sewage treatment station. |
