联合修复技术治理重金属复合污染农田的应用分析

Application Analysis of Joint Restoration Technology in Treating Heavy Metal Compound Polluted Farmland

本文以实际项目为例,探究联合修复技术治理矿区重金属复合污染农田的应用效果。项目通过改变当地耕作方式(水改旱),采用“土壤原位钝化+低积累作物种植”的联合修复模式,实现农用地污染风险管控和安全利用。本研究可为矿区重金属污染农田规模化修复治理提供技术支持。

Taking the actual project as an example,this paper explores the application effect of joint restoration technology to control the compound polluted farmland of heavy metals in mining areas.By changing the local farming methods (paddy fields to dry fields) and adopting the joint restoration model of "soil in-situ passivation + low-accumulation crop planting",the project realizes the pollution risk control and safe utilization of agricultural land.This research can provide technical support for the large-scale restoration and treatment of heavy metal polluted farmland in mining areas.
