中文摘要：

黄土在我国广泛分布，而我国煤矿企业，为维持煤矿采掘正常进行。都要排放SO4^2-离子含量很高的酸性矿坑废水。本文通过分析黄土与煤矿酸性废水的成分以及可能发生的反应，来阐述利用黄土处理煤矿酸性废水的可行性。

英文摘要：

In order to keep the normal excavating of coalmines, the acidic-waste water with the high amount of SO4^ would be discharged from mine pits. Since there is a wide distribution of loess in China, the feasibility of the treatment of the acidic-waste water by using loess is expounded based on the composition analysis of loess and acidic-waste water and on the possible chemical actions.
