Skid-mounted injection-aeration coupling equipment for contaminated site remediation and use method

Abstract

The invention relates to skid-mounted injection-aeration coupling equipment for contaminated site remediation and a use method. Multiple groups of passages for prefabricating medicaments are arrangedin a container body, the system comprises a medicament initial preparation unit, a first power transmission unit, a medicament temporary storage unit and a second power transmission unit which are connected in sequence, the second power transmission unit is connected to a medicament injection unit to complete injection operation, and a compressed air supply device is employed to adjust the workingpressure of the medicament temporary storage unit and the medicament injection unit; in the operation process of the whole equipment, control and adjustment are conducted through control of a controller and signal data fed back by a sensing unit. The equipment provided by the invention is mainly used for in-situ remediation of a contaminated site, can be used for high-pressure injection and medium-low-pressure injection, is suitable for contaminated sites of various geologies, has strong medicament mixing performance, is capable of conducting liquid injection, liquid gas injection, aeration and other remediation operations on contaminated areas, also has the functions of dredging injection wells, rapidly adjusting injection pressure and the like, and has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment and regeneration of polluted soil, and in particular relates to a skid-mounted injection-aeration coupling equipment and a usage method for remediation of polluted sites. Background technique [0002] In recent years, with the acceleration of my country's urbanization process and the implementation of the national policy of "retreating from the second to the third" and "retreating from the city to the garden", a large number of important industries such as metallurgy, chemical industry, petrochemical, steel, pesticide, and machinery manufacturing have emerged. The sites left behind by the relocation of enterprises in polluting industries have discharged a large amount of pollutants such as heavy metals, volatile organic compounds, pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and flame retardants during the production process for many years, seriously polluti...
