An important issue for landfills is leachate contamination control. After the landfill starts, due to the inflow of rainwater and surface water, as well as the decomposition of the garbage itself, a large amount of sewage is produced, which we call leachate. This liquid pollutant is high in content and complex in composition, and quickly penetrates into the ground, which will lead to serious pollution of groundwater for hundreds of years.

In this case, the geomembrane is particularly important as an important barrier in the anti-seepage system. Brand new imported resin raw materials, production lines and strict quality control of geomembrane are the prerequisites for a firm and reliable impermeable barrier. Therefore, a considerable number of newly built landfills in China, including those that need to be renovated, are required to use geomembrane products.

After the landfill is used for a period of time, a large number of flies will breed due to the increase of garbage, and the odor emitted by the garbage will also affect the surrounding environment. Therefore, it is necessary to seal the landfill every once in a while. As the main material for closing the landfill, the anti-seepage geomembrane has its own unique advantages.

First of all, as the sealing film of the landfill, the geomembrane has high air tightness, because the geomembrane is made of high-density polyethylene particles, and the product itself has high water impermeability and air impermeability, It can effectively prevent the breeding of flies, and at the same time, it can ensure that the odor of garbage in the landfill will not spread to the outside.

Secondly, geomembrane, as a sealing membrane for landfills, has high impermeability. Laying geomembrane on the garbage can not only prevent the breeding of flies and the spread of garbage odor, but also prevent the leakage of water such as rainwater and dew from the outside, and prevent groundwater pollution.

Geomembrane is used as a sealing membrane for landfills and has a long service life. The geomembrane itself is not easily decomposed. If buried in the ground, its service life can reach more than 50 years, and even if it is exposed, its service life can reach more than 5 years.
