Abstract

The invention provides a modularized movable soil leaching system. The modularized movable soil leaching system comprises: a soil feeding device, which is used for receiving contaminated soil and capable of discharging the contaminated soil while vibrating; a vibration feeding hole, which is used for receiving the contaminated soil discharged by the soil feeding device and quantitatively discharging the contaminated soil by controlling a vibration speed; a conveying belt, which is used for receiving and conveying the contaminated soil quantitatively discharged from the vibration feeding hole;a granularity screening machine, which is provided with a screening net and is used for screening the contaminated soil conveyed by the conveying belt into soil with granularity smaller than specifiedgranularity and contaminated soil with granularity larger than the specified granularity; a high-pressure leaching device, which is used for carrying out high-pressure leaching on the contaminated soil with the granularity smaller than or equal to the specified granularity received from the granularity screening machine, separating the contaminated soil into remediated soil and contaminants and discharging the remediated soil and the contaminants; and a screening device, which is used for receiving the remediated soil and the pollutants discharged by the high-pressure leaching device, discharging the remediated soil with granularity greater than the specified granularity as purified soil, and discharging the pollutants with granularity smaller than the specified granularity as waste waterwith.

Description

technical field [0001] The invention relates to the technical field of contaminated soil remediation, in particular to a modular mobile soil washing system. Background technique [0002] In soil remediation projects, pollutants such as polycyclic aromatic hydrocarbons, dioxins, pesticides, and heavy metals cannot be rinsed directly with clean water, so chemical extraction methods are used, but the equipment is very complicated when chemical extraction methods are used. [0003] In soil site remediation projects, soil leaching method is the mainstream technology for heavy metal or heavy metal and organic pollution complex pollution site treatment. [0004] Soil leaching technology is a technology that uses physical separation or leaching to separate heavily polluted soil components or transfer pollutants from the soil phase to the liquid phase by adding water or a suitable eluent. Compared with other remediation methods, the ex-situ soil leaching process has the advantages o...
