Embodiment Construction
[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Such as figure 1 As shown, the present invention provides a landfill anti-seepage system that prolongs the breakdown time of heavy metal ions. The anti-seepage system includes an anti-seepage cushion, a digital DC power supply 8, a current sensor 9, a computer 10 and an alarm device 11; The anti-seepage cushion layer includes the lower outer layer of high-density polyethylene geomembrane (HDPE) 5, the lower conductive geotextile 4, the middle bentonite clay layer 3, the upper conductive geotextile 2, and the upper outer layer of high-density polyethylene geomembrane (HDPE) laminated from bottom to top. Ethylene geomembrane (HDPE) 1; high-density polyethylene geomembrane and conductive geotextile are bonded with a liquid adhesive VAE with a viscosity of 1800; the upper conductive geotextile 2 is connected to the negative pole of digital...
