Abstract

The invention discloses an in-situ obstruction governing method of heavy-metal polluted soil. The method comprises the following steps of (1) drilling holes; (2) constructing a bottom obstruction layer; (3) constructing an anti-seepage obstruction wall; (4) pumping out underground water; (5) injecting a heavy metal stabilizer; and (6) building a top comprehensive obstruction layer. Through the way, by adopting the in-situ stabilized obstruction technology, the heavy-metal polluted soil can be in-situ governed efficiently, the governing effect is lasting, the economical cost is low, the application range is wide, whether the polluted soil area contains the underground water can be governed, the soil does not need to be dug in a large area, the risk in the digging process and transport process can be avoided, the secondary pollution and risk dispersion problems in the construction process can be greatly reduced, and the operation process is easy to control.

Description

technical field

[0001] The invention relates to the technical field of treatment and restoration of polluted soil, in particular to an in-situ barrier treatment method for heavy metal polluted soil. Background technique

[0002] Soil heavy metal pollution means that the heavy metal content in the soil is significantly higher than the original content. The heavy metal soil must be treated and repaired, otherwise it will cause the deterioration of the ecological environment quality and great harm to human health. At present, the cost of soil heavy metal treatment is high, and the treatment period is long. The treatment process will cause risks to the environment, such as risks in the excavation process and risks in the transportation process. Contents of the invention

[0003] The technical problem mainly solved by the present invention is to provide an in-situ barrier treatment method for heavy metal polluted soil with long-term treatment effect, low economic cost, wide app...
