With the aggravation of heavy metal pollution in farmland soils in China, traditional methods of remediation such as physical, chemical and biological methods are insufficient to completely meet the requirements of remediation. It is urgent to develop a technology that is efficient, stable, low-cost and has no secondary pollution. This paper reviewed the application and progress of geochemical engineering technology in remediating contaminated farmland soil, highlighted the fixation and deactivation of geochemical materials, geochemical engineering barriers, geochemical transformation-absorption-concentration and natural attenuation, meanwhile, the advantages, disadvantages and the development trend of this technology were also discussed and prospected. And Itis Suggested that attentions should be paid to the combination of various remediation technologies, the preparation of functionalized nanomaterials and magnetic nanocomposites, and the acceleration of theoretical achievements in soil remediation to practical application.
