Giải pháp bảo vệ môi trường và ngăn chặn ô nhiễm bãi chôn lấp

1.Industry Pain Points & Challenges The anti-seepage system in environmental engineering allows for meticulous attention to detail. Common technical challenges include:

(1) Toxic leachate leakage: Traditional concrete or clay layers are prone to micro-cracks, allowing pollutants to seep into groundwater.

(2) Chemical corrosion and aging: Waste is highly corrosive and accompanied by high temperatures, easily causing ordinary materials to become brittle and fail.

(3) Slope instability and landslides: Landfill slopes are steep, and the friction between the anti-seepage material and the soil is insufficient, easily leading to overall slippage.

(4) Complex construction environment: The open-air environment is subject to strong UV (ultraviolet) radiation, requiring extremely high weather resistance of materials.

2.System Solution

Changfeng has constructed a “multi-layer composite seepage prevention system”:

(1) Main seepage barrier: HDPE textured geomembrane is used, with the rough surface increasing the friction coefficient to ensure slope stability.

(2) Secondary self-healing layer: Sodium bentonite waterproofing blanket (GCL) is laid, its water-swelling property providing a “self-healing” function, serving as a double guarantee.

(3) Drainage and drainage layer: Composite drainage net or water storage and drainage board is used to quickly drain leachate, reducing pressure on the main membrane.

3. Những lợi thế cốt lõi

(1) Zero permeability standard: Changfeng HDPE geomembrane has a permeability coefficient of less than 1×10⁻¹³ cm/s, providing a near-absolute seepage barrier.

(2) UV Resistance 50+ Years: Utilizing 100% virgin resin with added anti-aging agents, it guarantees a service life of over 50 years even under direct sunlight.

(3) Slope Stability Improved by 60%: The textured surface design provides a significantly higher interfacial friction angle than smooth surfaces, supporting steeper slopes and increasing landfill capacity.
