有机污染土壤植物修复技术研究

Analysis on Phytoremediation Technology of Organic Polluted Soil

近年来,土壤有机污染形势也非常严峻,不仅破坏土体健康,影响植物正常生长,还会严重危害人体健康。植物修复技术具有彻底解决土壤污染、避免二次污染及改良土壤等优势,作为一种环境友好、成本低廉的污染治理手段,应用前景广泛。本文通过大量文献,探讨了植物对不同类有机污染土壤的修复机理,现状及影响因素,为土壤有机污染修复实践提供依据。

In recent years, the situation of soil organic pollution is quite serious. It not only destroys the health of the soil, the normal growth of plants, but also seriously harms the human health. Phy-toremediation technology has the advantages of completely solving soil pollution, avoiding sec-ondary pollution and improving the soil quality. As an environmentally friendly and low-cost pol-lution remediation method, it has broad application prospects. Through a large number of literatures, this paper discussed the repair mechanism, current status and influencing factors of different organic pollutants on plants, and provided the basis for phytoremediation practice of organic contaminated soil.
