Composite geomembrane is a composite material composed of different materials. It has certain permeability and anti-seepage properties and is widely used in soilengineering and environmental engineering. As a soil pollution control material, composite geomembrane has high adsorption, isolation and stability, and caneffectively reduce soil pollution.

First of all, composite geomembrane has strong adsorption properties. Composite geomembrane materials often contain active ingredients with good adsorptionproperties, such as activated carbon that adsorbs heavy metals. These adsorbents can adsorb harmful substances in the soil, such as heavy metal ions, organicpollutants, etc., reducing their migration and diffusion in the soil, thereby achieving the purpose of reducing soil pollution.

Secondly, composite geomembrane has good isolation performance. Composite geomembrane has high physical barrier properties and can effectively isolateharmful substances in the soil from the external environment. For example, in soil remediation projects, composite geomembranes can be used as an isolation layerto avoid contact between contaminated soil and surrounding healthy soil, reducing the penetration and spread of pollutants, thereby effectively reducing soilpollution.

In addition, the composite geomembrane has good stability. The materials of composite geomembranes usually have high durability and stability, and can maintain

their physical and chemical properties for a long time. This is important for soil pollution control, which often requires long-term and sustained measures.

The stability performance of the composite geomembrane can ensure that it can effectively prevent the migration and diffusion of soil pollutants in the long term

and reduce the further spread of soil pollution.

However, it should be noted that composite geomembranes cannot completely solve the problem of soil pollution. It is only an auxiliary means and can be used in

combination with other measures in soil pollution control to achieve better control results. Because the composite geomembrane mainly blocks and adsorbs the

migration and diffusion of soil pollutants in the soil, it cannot fundamentally solve the source problem of soil pollution.

In summary, composite geomembrane, as a soil pollution control material, has good adsorption, isolation and stability, and can effectively reduce soil pollution.

However, it needs to be used in conjunction with other measures and cannot completely solve the problem of soil pollution. Therefore, in practical applications,

comprehensive consideration should be given to specific situations and multiple means should be adopted to comprehensively control soil pollution to achieve

better control results.
