Description

Closing cover for in-situ repair system

Technical Field

The utility model relates to the technical field of the environment, concretely relates to normal position is closing cap for repair system.

Background

After 30 years of rapid industrial development, a large amount of pollutants enter soil and underground water through ways of solid waste stacking and dumping, sewage leakage, atmospheric sedimentation and the like, so that a large amount of chemical pollution plots are generated. The chemical pollution plots are largely included in the scope of re-development and utilization along with the planning of urbanization development. The pollution depth of part of chemical polluted plots is deep and reaches below 15 meters below the ground, so that the chemical polluted plots are not suitable for being repaired by adopting an excavation-treatment mode. A number of in situ remediation techniques are used for contaminated sites with deep contamination depths, such as in situ oxidation techniques, multiphase extraction techniques, air aeration techniques, and in situ heating techniques.

The in-situ heating mainly relates to two modes of in-situ resistance heating (ERH) and in-situ heat conduction heating (TCH). The resistance heating mode is mainly characterized in that electrodes are distributed in a polluted site to form a current path to heat the polluted soil. The thermal conduction heating mainly adopts the way that fuel gas is introduced into a polluted land block for combustion, then local high temperature is formed, and the local high temperature is conducted to the periphery to achieve the purpose of heating soil. Thermal conduction heating can also be achieved by directly introducing hot steam into the contaminated site, which diffuses to the surrounding area by thermal conduction to achieve heating of a larger area.

The existing in-situ thermal desorption technology for repairing polluted sites has limited cases, mainly because the in-situ thermal desorption technology generally needs to arrange a vertical curtain on a polluted source region, the ground needs to be hardened to prevent the pollutants from escaping from the ground under the condition of soil heating to cause secondary pollution, meanwhile, the existing ERH and TCH technologies need to arrange a large number of heating wells and invest a large amount of electric energy or fuel consumption, and the TCH and ERH technologies have the other defect that the adjustment during the repairing is difficult. In addition, the in-situ thermal desorption repair technology used at present needs to invest a very large amount of cost for polluted sites with deep pollution depth, and the engineering construction difficulty is also very high.
