我国农田土壤重金属污染修复技术研究

Study on remediation technology of heavy metal pollution in farmland soil in China

污染物的肆意排放导致土壤的重金属污染不断加剧,农田土壤重污染的面积进一步扩大,直接影响农作物的产量以及品质,对人身健康造成严重的威胁。然而,所处地区不同,污染程度也不尽相同。对程度不同的农田土壤重金属进行修复,一方面能够有效提升修复效率,另一方面能够节省资金成本。因此,对不同程度农田土壤重金属技术进行深入探究,具有重要的意义。

Bulk contaminants have been intentionally discharged but no preventive measures have been implemented.This has led to an increase in soil heavy metal pollution and an increase in the area of heavily polluted farmland soil.Based on this situation,our country has begun to focus on the management of soil pollution.However,the pollution varies from location to location.Rehabilitating heavy metals in agricultural soils of varying degrees can,on the one hand,effectively improve the efficiency of rehabilitation and,on the other hand,save money.Therefore,it is of great significance to in-depth exploration of soil heavy metal technologies in different degrees of farmland.
