1、 Construction methods and techniques of anti-seepage film for fish ponds 1. Drain the water in the pond, clean the silt and other debris, and then air.
Construction Technology of Rainwater and Wastewater Diversion Cover Film for Garbage Landfill Site
The thickness of anti-seepage film used in landfill sites is generally between 1.5mm and 2.0mm; Smooth geomembrane can be used for paving, and rough geomembrane must be used for slopes. Sealing also requires the use of HDPE geomembrane with a new material thickness of 1.5mm for anti-seepage.
The anti-seepage film for landfill sites, also known as HDPE geomembrane, is a waterproof and barrier material based on polyethylene native resin. The main components are 97.5% high density polyethylene, about 2.5% carbon black anti-aging agent, ultraviolet absorber, stabilizer and other auxiliary materials.
Special anti-seepage membrane for landfill site Use: Engineering anti-seepage membrane material: high-density polyethylene anti-seepage membrane waterproof blanket for landfill site
Summary: How to select materials and how to construct the rainwater sewage diversion covering film is a problem. Let me share with you: the environmental harm caused by the leakage of garbage landfills is enormous, and the generated leachate can penetrate underground and pollute groundwater, causing serious harm to human health.
The treatment cost of leachate is very high. In order to avoid the increase of leachate caused by rain, a layer of high-density polyethylene geotextile film needs to be laid on the surface of the garbage to separate rainwater from sewage, so that rainwater no longer enters the landfill site, but is discharged through the surrounding drainage outlets. The temporary coverage of rainwater and sewage separation in the landfill site usually uses 0.75mm geotextile film, and the mid-term coverage uses 1.0mm or 1.5mm HDPE geotextile film, The final coverage adopts 2.0mm HDPE geomembrane.
The landfill site adopts high-density polyethylene geomembrane with a thickness of 1-2 millimeters. The environmentally friendly landfill with processing technology has been widely promoted and used nationwide.
