【摘要】 以某炼油厂地下水石油类污染系统为研究对象,分别采集土壤及地下水样品进行土柱淋滤实验,通过对其分析,得出该地下水系统的污染途径主要有沟渠及污水坑渗漏、跑冒滴漏事故造成渗漏、污染土层及垃圾坑面状淋滤;地下水系统石油烃污染物的存在形式有溶解油、乳化油和吸附油;三种污染机制分别是通过石灰岩直接入渗、双层介质入渗和地下水二次污染。更多还原

【Abstract】 The petroleum hydrocarbon contaminant can enter into soil in oil industry and have bad influence on environment pollution.Taking a refinery’s oil pollution system in groundwater as the research object,the samples of soil and groundwater are analyzed.It is concluded that the leakage of cesspit,leakage of accident,source filtering of contaminated soil and filtering of cesspit’s sewage are the main reasons of the pollution,and that the emulsive oil,dissolved oil and adsorbed oil are the format of petroleum contaminator in groundwater system.Mechanisms of pollution are the direct seeping through calcareousness,seeping through double medium and the second contamination of contaminated water.更多还原
