摘要
近年来,随着中国经济社会的不断发展,城市化进程的不断推进,许多老工业企业尤其是选矿企业因搬迁或破产而遗留了大量的重金属污染物浓度较高的污染土地。这些地块如果想要达到安全利用的目的,就必须要将进入到土壤中的重金属污染物进行清除或控制。当前中国土壤污染引起公众越来越多的关注,因此,土壤重金属污染场地亟需实施治理与修复。土壤重金属污染的治理和修复能够改善土壤环境质量,确保土壤得到再次安全利用,减少土壤污染对周边环境的影响和对周边居民环境的破坏,提高土壤安全性。
With the continuous development of China's economy and society and the continuous advancement of urbanization in recent years,many old industrial enterprises,especially the mineral processing enterprises,have left a large number of polluted land with high concentration of heavy metal pollutants due to relocation or bankruptcy.To reuse those plots safely,heavy metal pollutants in the soil must be removed or controlled.At present,the soil pollution in China has attracted more and more attention from the public.Therefore,the soil heavy metal pollution site needs to be treated and repaired.The treatment and remediation of soil heavy metal pollution can improve the quality of soil environment,ensure the safe use of soil again,reduce the impact of soil pollution on the surrounding environment and the destruction of the surrounding residents'environment,and improve the soil safety.
