Polluted soil layer detecting and repairing device

The invention relates to the technical field of polluted soil detection and remediation, and provides a polluted soil layer detection and remediation device which realizes real-time detection and remediation treatment of a polluted soil layer through four action mechanisms of hot air blowing, negative pressure absorption, identification of volatile organic compound concentration through bionic olfaction and medicament injection. A common gas chromatograph, a common photoionization detector, a common halogen specific detector, a common flame ionization detector and a common canned inert gas are omitted and replaced by the bionic olfactory sensor integrated device, the number and complexity of equipment are greatly reduced, field installation, detection and repair are facilitated, meanwhile, a medicament dispensing module and an injection module are added, and the cost is reduced. And real-time detection and repair are realized. The mechanism and the equipment are innovated, so that the detection efficiency is
