| 摘 要： | 选择砂泥岩、砂岩、白云岩和灰岩作为代表性岩样,分别用模拟的生活、工业和农业污水进行淋滤,建立各污染物的净化曲线,计算净化量,得出净化系数。通过地下水流速、岩石裂隙率及污染物浓度三方面的修正,得出接近于实际的环境容量系数,其结果是:砂泥岩的净化能力最强,砂岩次之,白云岩和灰岩最差。

| Abstract: | The rock clean capability for contaminant is measured by absorbed experiment of rock in thelaboratory, according to the difference between the laboratory condition and the field condition. Thepractical environmental capacity is gained after revising the experimental data. The four rock samples,including siltstone, sandstone, dolomite and limestone, are used as representative rock samples. Theserock samples are leached by three kinds of contaminated water that simulated industrial, agriculturaland daily life polluted water. Based on the experimental result, the diagram of lean curves and volumeis plotted, and one can calculate the clean coefficient. The environmental capacity coefficient closelyrelated to the practical condition is gained after that the experimental data are revised in respect of ve-locity of ground water, fracture rate of rock and concentration of contaminant. The calculated resultshows that the clean capability of siltstone is stronger than that of sandstone, the clean capability ofdolomite and limestone are the weakest. |
