Description
technical field [0001] The invention relates to the technical field of soil remediation, in particular to a device and method for collecting gas in soil polluted by volatile organic compounds. Background technique [0002] According to the current Soil Pollution Survey Bulletin: Soil organic matter pollution is very serious, organic matter pollution has surpassed heavy metal pollution and radioactive pollution and has leapt to the first place; soil polluted by various organic matters (pesticides, petroleum hydrocarbons and polycyclic aromatic hydrocarbons, etc.) is as high as millions Hectares, most of the polluting organic substances are highly toxic, highly carcinogenic, and volatile substances, which seriously endanger the health of residents and the safety of the ecological environment. Therefore, it is urgent to remediate soil contaminated by organic matter. [0003] Ascertaining the types and contents of polluting organic matter in soil polluted by organic matter is t...
