| 摘 要： | 目的]研究莠去津在原状土柱中的运移,判断其在土壤中的移动性及其对地下水的危害性。方法]以4个大型原状土柱为试验载体,分别施用莠去津,用CXTFIT软件模拟莠去津的穿透曲线,率定吸附和降解参数,并与批次试验所得相应参数进行比较。结果]莠去津易随着土壤水分运动,如果施用不合理,莠去津污染浅层地下水的可能性很大。CXTFIT的非平衡模型比平衡模型能更好地模拟莠去津的穿透曲线。结论]可以结合土柱试验和批次试验的结果进行大尺度莠去津运移模拟和预报。

| Abstract: | Objective]The aim was to study migration of atrazine in undisturved soil columns and determine its mobility in soil and its hazard impact on groundwater.Method]With four large undisturved soil columns as test vector applied with atrazine,CXTFIT was used to simulate penetration curve,absorption rate,degradation parameters of atrazine,and compared with corresponding parameters in batch tests.Result] The results showed that atrazine can easily leach to the bottom of columns and then implies a high risk of g... |
