Problems solved by technology

Due to the heterogeneity and anisotropy of the soil medium, the introduction of external force is difficult to reach the expected position, so the restoration results often fail to achieve the expected effect
At the same time, due to the introduction of external force, the cost of various repair methods is also quite expensive

Abstract

The invention discloses a capillary evaporation membrane for soil remediation. The capillary evaporation membrane comprises a blocking membrane layer laid on the surface of soil, capillary terminals distributed on the blocking membrane layer, and a capillary membrane layer laid on the capillary terminals, wherein the capillary terminals pass through the blocking membrane layer, one ends of the capillary terminals are contacted with the capillary membrane layer, and the other ends of the capillary terminals are contacted with the soil. The capillary evaporation membrane for soil remediation canstop the natural evaporation of the soil surface layer and enable the evaporation to occur on a capillary evaporation membrane body, so that the water in the soil with the soluble matters brings thesoluble matters out of the soil and is enriched in the evaporation membrane, and the contaminants are further removed from the soil.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a capillary evaporation film used for soil treatment. Background technique [0002] Since the beginning of human industrialization, pollution has been accompanied by the process of industrialization. Since the 1950s, in order to curb pollution, various protective measures have emerged in an endless stream. Compared with the control of more and more pollution sources, the pollution that has been produced, especially the pollution of soil, has become the focus of environmental problems. Various methods of remediation of contaminated soil have emerged one after another. Generally speaking, from a broad perspective, there are in-situ restoration and ex-situ restoration, and the methods used include physical restoration, chemical restoration and phytoremediation. The common point of all these methods is to use external force to remove pollutants in the ...
