土壤重金属污染治理与修复方法研究进展

土壤重金属污染的治理和修复的基本原理是将重金属清除或改变其在土壤中的存在形态,降低迁移性和生物可利用性。根据土壤的性质和重金属在土壤中的赋存形态不同,目前重金属污染土壤治理和修复方法可分为工程物理化学法、土壤农化调控法和生物学修复法。通过对重金属污染治理与修复方法的综述,得出了各种方法的优缺点和适用范围,并对重金属治理的方法进行了展望。

Advance in the study on recovery and remediation of heavy metals pollution in soil

Soil pollution of heavy metals is become serious with the development of the social produce,and the heavy metals in soil are the potential threat to the plant and human body.The principle of recovery and remediation of heavy metals pollution in soil is to clear or to change the fraction transformations of heavy metals and which can decrease the mobility and the availability of heavy metals in soil.According to the soil characteristic and the heavy metals fraction transformations,the methods of recovery and ...
