Geomembrane, a membrane made of polymer materials, is used in many fields, especially garbage dump anti-seepage and rainwater and sewage diversion projects, with its excellent waterproofing, anti-seepage, deodorization, biogas collection, corrosion resistance and anti-aging characteristics. plays an irreplaceable role.
一. Basic characteristics of geomembrane
Geomembrane is a waterproof barrier material based on high molecular polymer, low density polyethylene ( LDPE） Geomembrane, high density polyethylene ( HDPE） Geomembrane is a film material with high strength, high corrosion resistance, high aging resistance and good anti-leakage performance. The core advantage of geomembrane lies in its excellent anti-leakage performance, which can effectively prevent liquid penetration and protect groundwater and soil from contamination. The construction process of geomembrane is relatively simple and easy to operate, which can shorten the construction period and improve the construction efficiency. It is mainly used in landfill, tailings storage yard, channel anti-seepage, dam anti-seepage and subway engineering, etc.
二. Application of geomembrane in anti-seepage of garbage dump
In environmental protection projects such as landfills, geomembranes, as impervious layers, play a vital role. With the acceleration of urbanization, waste disposal has become an important part of urban management. Traditional landfill methods often have the risk of leachate contaminating groundwater and soil, and the application of geomembranes effectively solves this problem.
1.Prevent leachate contamination ：By laying geomembranes at the bottom and around the landfill, a solid anti-seepage barrier is formed, which effectively prevents landfill leachate from penetrating into groundwater and soil and protects the safety of the surrounding environment.
2. Improving landfill stability ：Geomembrane not only has anti-seepage function, but also enhances the overall stability of the landfill and prevents potential safety hazards such as foundation settlement and landslides caused by leachate accumulation.
3. Reduce maintenance costs ：The use of geomembranes reduces the need for leachate treatment and reduces subsequent maintenance costs while extending the life of the landfill.
三. The key role of geomembrane in rainwater and sewage diversion projects
Rainwater and sewage diversion is an important direction of urban drainage system construction, aiming at collecting, transporting and treating rainwater and sewage separately to improve the utilization efficiency of water resources and water environment quality. Geomembrane also plays a key role in this project.
1. Achieve effective separation of rainwater and sewage ：By laying geomembranes in key parts such as regulating tanks, a physical isolation layer between rainwater and sewage is formed to ensure that rainwater does not enter the sewage system and reduce sewage treatment load and operating costs.
2. Improving water quality ：The anti-seepage performance of geomembrane effectively prevents harmful substances in sewage from spreading to the surrounding environment, and protects the water quality safety of surface water and groundwater.
3. Enhanced system stability ：The high strength characteristics of geomembranes allow them to withstand natural impacts and weather changes, ensuring the stability and reliability of rainwater and sewage diversion systems.
四. Future development trends
With the enhancement of environmental awareness and the continuous progress of technology, the application of geomembranes in garbage dump anti-seepage and rainwater and sewage diversion projects will be more extensive and in-depth. In the future, expand the application of geomembranes in more fields, such as agricultural irrigation, ecological restoration, etc., to promote its development to a wider market.
To sum up, geomembranes play an irreplaceable role in garbage dump anti-seepage and rainwater and sewage diversion projects with their unique performance advantages. With the continuous progress of technology and the continuous expansion of applications, geomembranes will play a more important role in future environmental protection and contribute to the construction of a green and sustainable urban environment.
