Abstract

The invention provides a safe ecological system for treating heavy metal solid waste. The safe ecological system comprises a reservoir bottom foundation layer, an underground water diversion layer, acompacted clay layer, a leachate diversion layer, a waste pile body layer, a closure middle earthing layer, a closure exhaust layer, a closure compacted clay layer, a closure drainage layer, a nutrient soil layer and an ecological greening layer. A first geomembrane is arranged between the reservoir bottom foundation layer and the underground water diversion layer; a second geomembrane is arrangedbetween the underground water diversion layer and the compacted clay layer; a third geomembrane and a fourth geomembrane are arranged between the compacted clay layer and the leachate diversion layer; and a fifth geomembrane is arranged between the leachate diversion layer and the waste pile body layer. The geomembranes in the system can achieve the effects of protection, blocking and isolation,and the content of heavy metal in the nutrient soil layer is greatly reduced. The ecological greening layer adopts multi-element integrated matching of trees, shrubs and grass to realize ecological restoration. The safe ecological system has the advantages of high anti-seepage standard, low secondary pollution risk and high environmental safety.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a safe ecological system for treating heavy metal solid waste. Background technique [0002] With the development of agriculture, science and technology and the continuous improvement of people's living standards, the output of domestic garbage and industrial solid waste is showing a rapid growth trend. A large amount of various solid wastes not only occupy a large amount of land, pollute farmland, air and water, but also easily spread diseases. Therefore, solid wastes need to be properly disposed of. [0003] At present, the treatment methods of solid waste mainly include thermal treatment technology, biological treatment technology, solid treatment technology and final treatment technology. Among them, safe landfill in the final treatment technology is a solid waste treatment method widely used in China. Heavy metals are more harmful to the human body. For exampl...
