| 摘 要： | 研究了污水灌溉过程中可能发生的土壤与污水间的离子交换问题，建立了符合离子交换实际过程的数学模型，并通过物理模型实验进行了验证，在此基础上，定量预测了污水灌溉可能带来的各种影响，即地下水硬度升高和土壤含氮量的增加。

| Abstract: | The problem of ion exchange between soil and percolating water in the process of wastewater irrigation is studied. The results obtained from exchange adsorption experiments indicate that this process can be described by a mathematical model of local ion exchange equilibrium. On this basis, the effects which take place in wastewater irrigation. such as the increase in hardness of groundwater and the increase of N content in soil, have been predicted. |
