摘要
在处理受到酸污染的拟建场地时，为避免开挖回填造成二次污染，最佳的处理方法就是原位就地处理。上海某铜厂不锈钢工程应用换水法处理硫酸污染地基，利用人工方法边抽水边压水，往地基土中压入碱水，碱水通过渗透的方式与酸发生中和反应，以消除酸性。处理区域内土壤和地下水原pH值在4～5之间，处理后其pH值在7～9之间，满足设计要求，达到了预期的效果。相比其他处理方法，该方法具有经济、环保等特点。
In order to avoid the second pollution which caused by excavation and backfill, the optimal treatment is in-situ treatment on processing its planned building. The authors treat foundation which is polluted by sulfuric acid, pump and press by artificial method, press alkaline water into foundation soil. The alkaline water reacts on with to neutralization reaction through penetration to eliminate acidity. Before treatment, the pH values of soil and underground water are between 4 and 5, after treatment the pH values of them are between 7 and 9. The method satisfies design demand, achieves anticipative effect. Compared with other treatment, the characteristics of this method are economic and environmental-friendly.
