摘要
以焦作市演马矿煤矸石堆周围环境中重金属为例,通过对其表层土壤污染状况的分析,提出了利用重金属超积累植物的提取作用,发挥植物的挥发作用及固化植物的稳定作用,在稳定污染土壤减少风蚀、水蚀及防止地下水二次污染的同时,使污染土壤得以修复的方法。
Taking heavy metal in the coal waster rock pile＇s surrounding environment of Jiaozuo city Yanma mine for example, based on the analysis of its topsoil＇s pollution situation, the author provides the method that using the extraction effect of heavy metal hyper-accumulator plants, volatilizing plant＇s volatilization and curing plant＇s stabilization effect, at the same time, stabilizing contaminated soil and reducing wide erosion, water erosion and preventing the second pollution of underground water, thus repairing the contaminated soil.
