Process of botany for repairing soil composite polluted by polycyclic aromatic hydrocarbon

Abstract

A phytologic method for repairing the soil polluted by polycycloarylhydrocarbon features that the leguminous plant such as alfalfa, trifolium, etc is planted in said polluted soil and it is harvested after it is growing for 85-95 days.

Description

technical field

[0001] The invention relates to a biological environmental protection technology, in particular to a method for reducing polycyclic aromatic hydrocarbon compound pollutants in soil: a botanical method for repairing polycyclic aromatic hydrocarbon compound polluted soil. Background technique

[0002] Polycyclic aromatic hydrocarbons (Polycyclic Aromatic Hydrocarbons, PAHs) widely exist in the environment, such as soil, sludge, water, oil and other media, it is a typical class of persistent organic pollutants, with high carcinogenic, teratogenic, mutagenic , pose a greater threat to ecological environment security and human health. Therefore, the control and remediation of persistent organic pollutants such as polycyclic aromatic hydrocarbons in soil has become an important research content in the field of environmental science and technology at home and abroad. Remediation methods for contaminated soil mainly include chemical, physical, microbial and phytorem...
