Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0026] Such as figure 1 As shown, a method for evaluating ecological restoration technology of heavy metal-contaminated soil in a typical mining area in this embodiment generally includes the following steps:

[0027] (1) Determination of evaluation objects and evaluation indicators

[0028] The current status and technical research progress of ecological restoration of heavy metal-contaminated soil in mining areas at home and abroad were investigated through literature research, field investigation, and experimental testing. Combined with the research status of ecological restoration technology of heavy metal-contaminated soil in mining areas at home and abroad and the development trend of ecological restoration of heavy metal-contaminated soil in mining areas in my country, the evaluation indicators for ecological restoration technology of heavy metal-c...

Abstract

The invention discloses a typical mine area heavy metal pollution soil ecological restoration technology evaluating method, which comprises the following steps that (1) an evaluation index system is built; (2) the scoring is carried out by experts, each level judgment matrix is built, and the index weight is calculated; (3) evaluation index standards are determined; (4) a typical mine area heavy metal pollution soil ecological restoration technology comprehensive evaluation mathematical model is built; (5) a typical mine area heavy metal pollution soil ecological restoration technology evaluating system is developed. The invention also provides the typical mine area heavy metal pollution soil ecological restoration technology evaluating system. The evaluating method is combined with a computer technology, a fast and practical auxiliary decision making tool is built, the scientific basis can be provided for selecting the proper typical mine area heavy metal pollution soil ecological restoration technology in the five aspects including technical performance, governance cost, environment influence, resource utilization and regional harmony performance, and the accuracy and the efficiency of the evaluation work are greatly improved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an evaluation method and system for ecological restoration technology of heavy metal polluted soil in typical mining areas. Background technique [0002] Due to the hidden, long-term and irreversible characteristics of heavy metal pollutants in the soil, using physical and chemical engineering methods to treat them will not only lead to soil structure damage, activity and fertility degradation, but also require a large amount of treatment work and high repair costs. It is difficult to control large-scale pollution, and it may even cause secondary pollution to the environment. Ecological restoration technology is based on ecological principles, using specific organisms (such as repairing plants or obligate degrading microorganisms, etc.) , A comprehensive environmental pollution control technology that can restore the polluted environment. It overcomes the shortcomings of...
