A revolutionary solution has emerged for landfill leakage pollution! Leachate leakage rates have dropped below 0.5%, with anti-seepage efficiency improved by over 90%. This technology is projected to be implemented in 200 landfills nationwide within three years, advancing the "zero-pollution landfill" goal.
I. Technical Principle: How does geotextile reconstruct the Anti-seepage System
Composite Layering:
"One fabric, one membrane" or "two fabrics, one membrane" structure (non-woven fabric + HDPE geomembrane), increasing tear resistance by 3 times.
Four-Dimensional Protection:
Heavy metal isolation (zero soil contact), suspended solids filtration (99% interception rate), efficient leachate drainage, and reinforcement against settlement (tensile strength ≥50 kN/m)。
Ⅱ. Application Scenarios: Full coverage from the bottom to the closure of the venue
Bottom Anti-Seepage Layer:
Composite geotextile ≥1.5 mm thick blocks leachate from contaminating groundwater. Data from Xuzhou project show groundwater pollution index dropped to 0.3 (safety threshold ≤1).
Slope Reinforcement:
Woven geotextiles on slopes >30° increase anti-sliding force by 40%, eliminating landslide risks during rainy seasons.
Closure Cover System:
"Geotextile + vegetation layer" structure reduces rainwater infiltration by 80% and methane emissions by 65%.
Ⅲ. Economic Benefits: A win-win situation of cost reduction and carbon emission reduction
Cost Optimization:
Compared to traditional concrete barriers, geotextile solutions cut investment by 25% and shorten construction time by 50%. Example: Xianyang Wei River embankment project saved ¥68,200 for 500 meters.
Long-Term Carbon Reduction:
Single landfill reduces CO₂ emissions by 500,000 tons/year (equivalent to planting 3 million trees). If promoted nationwide, the annual potential for emission reduction will exceed 100 million tons.
