Problems solved by technology

[0003] The purpose of the present invention is to provide a treatment method for vegetation restoration of mine polluted land, aiming at the acidification and heavy metals that may reverse seepage in the deep layer of the mine when the soil acidification existing in open-pit mining metal mines and the vegetation restoration of bare mine land compounded by multiple heavy metals are recovered. The problem of ions polluting the vegetation layer of the mine surface and poisoning plants due to soil capillary action reverse osmosis

Abstract

The invention is applicable to the field of ecological remediation and provides a treatment method for recovering mine polluted land vegetation. The method comprises the following steps of eliminating large pumice stone or protrusion on the surface of a mine polluted land; preparing an obstruction, control and isolation material; spraying the obstruction, control and isolation material on the surface of the polluted land to form an obstruction, control and isolation layer; sealing and isolating the surface of the polluted land by use of the obstruction, control and isolation layer; reestablishing a vegetation layer on the obstruction, control and isolation layer by use of a fiber soil fixation and slope protection vegetation technology; planting plants on the vegetation layer so as to realize vegetation recovery. According to the treatment method, the obstruction, control and isolation layer is formed on the surface of a mine so as to achieve a physical and chemical sealing and isolation effect, acidic and heavy metal ions which are likely to be reversely permeated in the deep layer of the mine are prevented from being reversely permeated to the surface layer of the mine due to the soil capillary action, and the vegetation layer is reestablished on the obstruction, control and isolation layer, so that a mine soil environment with favorable physical and chemical properties can be provided for the growth and development of the plants, and thus the purposes of recovering the vegetation and conserving water and soil can be achieved.

Description

technical field [0001] The invention belongs to the field of ecological restoration, in particular to a treatment method for vegetation restoration of mine polluted land. Background technique [0002] The ecological damage and environmental pollution caused by the open-pit mining and production process of metal mines are many, large, and wide-ranging, which poses a serious threat to the mining area and surrounding ecosystems, soil environment, and water environment. A worldwide problem of sustainable development. Especially for paragenetic (associated) mines with complex components, a large amount of solid waste with high heavy metal content is formed in the mining or already-mined area. Long-term exposure causes sulfur minerals to oxidize and cause soil acidification. The solid waste residue is washed and leached by rainwater, and the Toxic and harmful components infiltrated into the soil, causing soil acidification and heavy metal pollution, resulting in deterioration of ...
