| 摘 要： | 本次室内土柱淋滤实验通过改变Na~+、H~+、NH_4~+浓度来模拟现实生活中不同浓度的生活污水、酸雨及农业施肥灌溉对浅层地下水总硬度的影响过程。实验结果表明淋滤液浓度越高,所对应的淋出液的总硬度峰值就越高。相同浓度的Na~+、H~+、NH_4~+进行土柱淋滤实验时,NH_4~+所对应的淋出液总硬度的峰值最大,H~+次之,Na~+最小且NH_4~+所对应的整个实验用时最短,在相同浓度单一离子作用下NH_4~+对浅层地下水硬度的影响更加明显。

| Abstract: | By changing the concentrations of Na+, H+ and NH4+, this indoor soil column leaching experiment simulated the effects of different concentrations of domestic sewage, acid rain, and agricultural fertilization on the total hardness of shallow groundwater in real life. The experimental results showed that the higher the concentration of leaching solution, the higher the total hardness peak of the corresponding leaching solution. When Na+, H+ and NH4+ of the same concentration were used for soil column leaching experiments, the peak of the total hardness of the leaching solution corresponding to NH4+ was the largest, and H+ was the second, Na+ was the smallest and the entire experiment corresponding to NH4+ was the shortest. The effects of NH4+ on the hardness of shallow groundwater are more obvious under the action of a single ion at the same concentration. |
