| 摘 要： | 在研究了天津市浅部含水层和弱透水层的土样性质后，选出7类有代表性的土样，进行吸附实验研究，结果表明土样对锰的吸附符合Langnuir吸附模式。利用土柱实验确定锰在含水层迁移的弥散系数、弥散度和滞后系数，建立了锰在含水层中迁移的一维模型，并给出解析解。研究了锰在地下水中的迁移规律，表明锰在含水层中的迁移能力比较差，而且在有咸水区的迁移能力更差。

| Abstract: | After studying on the quality of earth samples that came from shallow aquifers and poorly permeable strata, authors choose seven representative earth samples, and make absorbing experiments. Law of adsorbed manganese accords with Langmuir adsorbed model. The dispersion coefficient, dispersivity and lag coefficients of manganese movement in aquifers are decided by earth experiment. The one-dimensional model of manganese movement in aquifers is established and its analytical solution is given. The moving laws of manganese in groundwater are studied. The moving ability of manganese is poor in aquifer and even poorer in salt area. |
