摘要
污染土壤如果不及时修复,土壤中的污染物会随着雨水渗入地下或者流入江河,进而扩大污染范围,所以,污染土壤修复技术备受重视。本文首先分析了物理、化学、生物、植物、纳米零价铁等土壤修复技术,然后从环境友好修复、复合型修复、原位土壤修复几个方面展望了修复技术的发展方向。
If the contaminated soil is not repaired in time,the contaminants in the soil will seep into the ground or flow into the river with rainwater,thereby expanding the scope of pollution,so the technology of contaminated soil remediation is paid more attention.This paper first analyzes soil remediation technologies such as physics,chemistry,biology,plants,and nano-zero iron,and then looks at the development direction of remediation technologies from the aspects of environmentally friendly remediation,composite remediation,and in-situ soil remediation.
