岩溶地下水渗漏污染研究

Study on the Seepage Pollution of Karst Groundwater

在贵州岩溶地区,由于废渣堆场选址和防渗处理措施不当,产生岩溶渗漏,使强酸碱废水污染了岩溶地下水,直接影响了岩溶水资源的开发利用。根据对各种废渣堆场渗漏污染的勘查,归纳出3种渗漏类型,并分析了污染效应,应用动态系统模型和混合稀释模型,进行了预测评价,为渗漏污染治理提出了治理措施并取得了显著的效果。

In karst areas of Guizhou,improperly located waste residue disposal sites and ineffective leakproof measurements lead to karst seepage.As a result,karst water is polluted by strongly acid and alkaline wastewater,which directly threatens the exploitation of karst water resources.Three types of seepage have been found out through prospecting pollution cases at various waste residue disposal sites.The leakage pollution is predicted and evaluated by applying prediction model of mixing diluted diffusion and dynamic system model of CAR.Integrated control measures are suggested and a remarkable leakproof effect is produced.
