重金属污染土壤的修复技术研究进展及发展前景

Research progress and develop prospects of recovery technique of heavy metal polluted soil

目前,我国重金属污染呈现出长期积累和近期集中爆发、历史遗留问题和新出现问题相交织的特点,重金属污染在环境中存在多、形态多,整治重金属污染是一项长期、复杂、艰巨的任务。重金属污染物极难降解,尤其是存在于水和土壤中的重金属兼具富集性,是不可逆转的。重点阐述了重金属污染土壤的修复技术研究进展及发展前景。

At present, the heavy metal pollution represents some characters that long-term accumulations combine with recent outbreak, the historical problems interweave with newly occurred issue. It is a long-term, complex and tough task to control heavy metal pollution with the large amount and diverse forms. The heavy metal polluters are hard for degradation, and the polluters enriched in water and soil are nonreversible. The research progress and develop prospects of recovery technique of heavy metal polluted soil were demonstrated.
