| 摘 要： | 阿特拉津是研究区内广泛使用的旱田除草剂。为治理其污染的地下水 ,采用静态和动态实验的方法研究其在含水介质砂层中的吸附特性和在地下水中的迁移转化规律。实验结果表明 :砂层对阿特拉津的吸附量小 ,不同固液比 (1.0、0 .5、0 .2 )时的分配系数分别为 0 .10 ,0 .15 ,0 .19cm3 /g ;含水层的弥散度为 0 .0 336m ,阻滞因子为 1.2 9,自然净化系数为 0 .0 0 2 8/d。由此确定所建立的数学模型和参数 ,为研究区阿特拉津污染地下水的治理提供可靠的依据

| Abstract: | Atrazine is a glebe herbicide used widely in study area. Its absorption characteristic by sand and transporting and transforming in groundwater were studied by means of the static absorpting experiment and dynamic transporting experiment for the treatment of groundwater contaminated by it in this paper.The results of the experiment are that the absorption amount is small and the distribution coefficient are respectively 0.10, 0.15, 0.19 cm 3/g according to the different ratio of sand and water (1.0, 0.5 ,0.2); the dispersion degree is 0.033 6 m, the retardation factor is 1.29 and the coefficient of natural purification is 0.0028/d. Thus the mathematic model and its parameters are determined and a reliable basis are provided for the research of remediation of groundwater contaminated by atrazine in study area. |
