Abstract

The invention relates to a stable curing repair system for polluted soil. The system consists of a dispensing tank, a chemical storage box, a centrifugal pump, a spraying device, a reaction tank, a recovery tank, a circulating pump, a backhoe excavator and a movable gantry mixer; the system can be used for rapidly repairing the polluted soil by adopting repair chemicals with different forms, types and concentrations at different temperatures according to the characteristics of the different polluted soil; the system is mainly suitable for the soil polluted by heavy metals such as Cr, Cd, Pb, Zn and Cu. The stable curing repair system is reasonable in arrangement, wide in application scope, rapid in reaction speed, short in repair period, good in flexibility, safe and stable in operation and economically feasible, and can be used for heterotopic or in-situ repair of the polluted soil; the repaired soil can meet the relevant standard, and comprehensive resource utilization of the polluted soil can be realized, so that the system has good environmental protection benefit and social benefit.

Description

technical field [0001] The invention relates to a stable solidification restoration system for polluted soil, which belongs to the category of environmental protection equipment. Background technique [0002] With the acceleration of my country's industrialization and urbanization process and people's increasing requirements for environmental protection, the relocation, suspension or closure of some industrial and mining enterprises have left a large number of polluted sites, the extensive use of pesticides, insecticides and fertilizers, and industrial "three wastes" The continuous increase of soil pollution has caused serious threats to human health. Soil pollution involves many industries such as chemical industry, mining, metallurgy, electroplating, oil refining, etc. The main pollutants include heavy metals, volatile organic compounds, semi-volatile organic compounds, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, petroleum hydrocarbons, pesticides, etc. Ho...
