| 摘 要： | 通过模拟海水入侵地下水过程的实验,研究了青岛地区海水对不同土壤浸泡上清液中各种元素的变化,得出了海水入侵过程中常规离子如Cl-、HCO3-、P和Ca2 的变化规律。与此同时,海水含有一定量重金属。在与不同土壤浸泡过程中,实验中分析了Ni、Cd、Cr、Pb、Cu、Mn和Zn共7种元素。上清液中Ni、Cd和Zn浓度增加,Pb、Cu和Cr的浓度略有降低或基本不发生变化。用饮用水和蒸馏水分别与不同土壤浸泡作参比实验,上清液中各种元素基本不发生变化。浸出液中基本上不含重金属。另外,应用海水、饮用水和蒸馏水与不同土壤浸泡时,所有上清液中均未检测出Mn元素。因此,海水入侵过程中,地下水不仅变咸,也使地下水重金属增加。

| Abstract: | By simulating intrusion process of seawater into underground water in Qingdao area,the changes of the elements concentration of Cl~-,HCO-3,P and Ca~ in the different soils was investigated.Meanwhile,concentration of heavy metals,such as Ni,Cd,Cr,Pb,Cu,Mn and Zn was also discussed.By soaking different types of soils,the concentration of Ni,Cd and Zn in the supernate increased,while the concentration of Pb,Cu and Cr decreased a little or showed no change.Mn was not found after mixing seawater,freshwater and de-ionized water with different soils.Therefore,with the intrusion of seawater,the ground water will be salter,and heawey metals concentrations will also rise. |
