Necessity of HDPE anti-seepage geomembrane for sewage pool

The pollution caused by direct discharge of sewage directly threatens people's health. First, pathogenic microorganisms in drinking water will cause the spread of infectious diseases. Second, the accumulation of toxic substances in the water through the food chain will cause acute and chronic poisoning, cancer and other public diseases. Therefore, the anti-seepage work of the sewage pool is very necessary. Generally speaking, the HDPE anti-seepage geomembrane is now used.

At present, the pools of sewage treatment plants usually adopt the structural types of reinforced concrete and earthen ponds, but these structural types have defects such as high engineering cost, complicated construction process, long construction period, easy cracking, etc., especially when applied to some large-volume pools (such as These defects are more prominent when adjusting the pool and aeration tank.

1. HDPE anti-seepage geomembrane has excellent chemical stability and is widely used in sewage treatment, chemical reaction tanks and landfills. Resistance to high and low temperature, asphalt, oil and tar, acid, alkali, salt and other 80 kinds of strong acid and alkali chemical medium corrosion.

2. The materials used in HDPE anti-seepage geomembrane are non-toxic and environmentally friendly materials. The principle of anti-seepage is ordinary physical changes, does not produce any harmful substances, and is a better choice for environmental protection, breeding and drinking water pools.

3, HDPE anti-seepage geomembrane has excellent puncture resistance and can resist most plant roots.

4, HDPE anti-seepage geomembrane has excellent anti-aging, anti-UV, anti-decomposition ability, can be used barely, the material service life is 50-70 years, providing a good material guarantee for environmental anti-seepage.

5. HDPE anti-seepage geomembrane has good mechanical strength, tensile strength at break of 28MP and elongation at break of 700%.

6. HDPE anti-seepage geomembrane has high flexibility. It has various specifications and various paving forms to meet different engineering anti-seepage requirements. It adopts hot-melt welding, high weld strength, convenient construction, fast and healthy.

7. HDPE anti-seepage geomembrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and quicker, so the product cost is lower than the traditional waterproof material. The actual project using HDPE anti-seepage film is cost-effective. %about.
