| 摘 要： | 为探索合理地除氟方法和工艺,提出利用人工土壤层处理含氟废水的方案,通过饱水动态土柱实验研究了氟离子在土壤层中吸附交换规律,探讨了土砂质量比例、渗滤厚度、淋滤液浓度等参数对土柱的吸附能力和渗滤速度的影响,得出土砂比参数为3:1,渗透厚度为 40cm的人工土壤层对氟离子具有良好吸附效果的结论,并在较大的氟离子浓度范围内均适用。

| Abstract: | Fluorine is one of the main sources of the environmental pollution. In order to explore the rational method and craft of removing fluoride, the paper puts forward the project of utilizing artificial soil layer removing fluoride. By soil column experiment study, the rule of soil adsorbing and exchanging fluoride is researched and the influence of some parameters such as the soil to sand ratio, leaching deepness and the concentration of solution, etc. is probed into. The result indicates: There is good effects on absorbing fluorine ion by artificial soil layer whose parameter cf soil to sand ratio is 3 :1 and parameter of permeable deepness is 40 cm. |
