摘要:

为研究重金属污染农田土壤的稳定化修复技术,通过实施云南省某农田土壤重金属污染修复项目,对各修复技术进行比选,对优选出的稳定化修复技术涉及的稳定化药剂进行归纳分析,并开展了小试—中试—工程实施系统的工艺研究、技术应用。结果表明:该技术保证了修复效果并降低了修复成本,实现了污染农田土壤的安全利用。形成了控源—减量—降活—低吸—农产品安全达标生产的修复模式,构建了具有针对性的稳定化—植物—农艺调控的联合修复技术体系,实现了重金属污染农田土壤修复、生态建设、经济效益的有机结合。

Abstract:

To study the stabilization remediation technology of heavy metal contaminated farmland soil, the remediation project of heavy metal contaminated farmland soil in Yunnan Province is carried out, to compare remediation technologies and summarize and analyze stabilization agents through the systematic process research and technical application of small-scale experiment, pilot-scale experiment and project implementation. The results show that the remediation technology could ensure the remediation effect and reduce the cost, and the safe utilization of heavy metal contaminated farmland soil has been achieved. The remediation mode of source reduction, concentration reduction, availability reduction, absorption reduction and safe production of agricultural products has been formed. The combined remediation technical system of heavy metal contaminated farmland soil has been established which includes stabilization, phytoremediation and agricultural ecological restoration technologies, to realize the dynamic integration of the remediation of heavy metal contaminated farmland soil, ecological improvement and economic benefits.

Key words: farmland, soil remediation, heavy metal, solidification/stabilization, remediation practice
