Progress in engineering application of remediation technology for contaminated sites with polycyclic aromatic hydrocarbons (多环芳烃污染场地修复技术工程应用进展)

In response to polycyclic aromatic hydrocarbon (PAH) contaminated sites, this paper systematically analyzes the progress in domestic engineering applications of mainstream remediation technologies such as thermal desorption, cement kiln co-processing, and chemical oxidation. The application principles, advantages, disadvantages, and costs of these technologies are introduced, providing references for the selection of remediation technologies for PAH-contaminated sites. The study further points out that sustainable green remediation is a future research direction in this field.
