耕地重金属镉污染安全利用修复

Safe utilization and remediation of heavy metal cadmium pollution in farmland

以新余市渝水区罗坊镇受污染耕地为例,概述受污染地块的污染现状,分析污染成因,通过参考相关技术文件,结合污染地块试验,针对其轻度镉污染特点,采取土壤调酸(洒石灰)、施用有机肥和低镉积累品种技术联合修复,以期达到治理效果,为政府决策提供参考。

The article takes the contaminated farmland in Luofang Town,Yushui District,Xinyu City as an example,outlines the pollution status of the contaminated land,analyzes the causes of pollution,and selects remediation techniques such as soil passivation technology,microfertilizer conditioning technology,and deep plowing and tilling for its mild cadmium pollution characteristics by referring to relevant technical documents and combining with experiments on the contaminated land,in order to achieve the treatment effect and provide reference for the government’s decision.
