| 摘 要： | 研究区位于河北省保定市东部排污渠旁，是一处有近40年污水灌溉历史的农田，灌溉用污水主要为保定天鹅化纤有限公司和保定钞票纸厂排放的污水，主要种植农作物为小麦、玉米。饱气带厚度2.4~2.7 m，饱气带土以粉质粘土为主。通过分析距排污渠不同距离、不同深度的土样有机物的测试分析结果，选择苯、甲苯、二氯甲烷、三氯甲烷、苯并a]芘为典型污染物，从饱气带土的物理与化学特征、5种有机物的物理化学特征、地下水的动力条件角度，分析了典型有机物在饱气带土与地下水中迁移的影响因素。

| Abstract: | The study area, a farmland near the eastern sewage outfall of Baoding, Hebei province, has been polluted by sewage irrigation over recent 40 years. The sewage mainly comes from Baoding Swan Chemical Fiber Co. Ltd. and Baoding Banknote Paper Mill, and the main crops are wheat and corn. Powdery clay is the main ingredient of the aeration zone and the thickness range of the aeration zone is between 2.4 m and 2.7 m. In this paper, samples of different depths and different distances from the outfall were collected for benzene, toluene, dichloromethane, chloroform, benzopyrene analysis. According to the physical and chemical characteristics of soil and typical pollutants in aeration zone and the dynamic conditions of groundwater, the influencing factors on the transport of typical organics were analyzed in aeration zone and groundwater zone. |
