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
