Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] A method for conditioning and repairing contaminated soil is provided, comprising the steps of:

[0017] (1) Conduct pollution trace investigation on the soil site to be treated, including confirmation of visible pollution sources, analysis of stains and corrosion traces, and determination of pollutant sources in the surrounding areas of the soil site, such as construction waste, containers, pipelines, etc. Confirmation of the location, type, and scale of visible pollution sources, analysis of vegetation damag...

Abstract

The invention discloses a method for conditioning and remediating polluted soil. The method comprises the steps: investigating a pollution trace of a soil site, selecting different soil samples to beanalyzed according to a network point distribution method, determining the distribution and pollution degree of a pollutant on the soil site; calculating and comparing a remediation target value of acarcinogenic risk of the orally taken pollutant in soil and a remediation target value of a non-carcinogenic hazard entropy of the orally taken pollutant in soil according to analysis results of different soil samples, and selecting a relatively small value as a remediation target value of a pollutant in a to-be-treated soil site; and formulating a conditioning and remediating scheme, applying a soil passivator to the soil site, and detecting the soil site to obtain a conditioned and remediated soil site. In such a way, it is ensured that the whole construction can be more comprehensively andaccurately planned before construction, the uncertainty in a construction process can be avoided, and the method is obvious in conditioning and remediating effects, wide in application prospect and very good in guiding significance to the remediation management of soil.

Description

technical field [0001] The invention relates to the technical field of polluted soil treatment, in particular to a method for conditioning and repairing polluted soil. Background technique [0002] Soil is a layer of loose material on the earth's land surface, composed of various granular minerals, organic matter, water, air, microorganisms, etc. Soil not only provides mechanical support for plant growth, but also provides fertility elements such as water, fertilizer, air, and heat for plant growth and development. Due to the rapid growth of population and the rapid development of industry, solid waste is continuously piled and dumped on the soil surface, harmful waste water is continuously infiltrated into the soil, and harmful gases and floating dust in the atmosphere are also constantly falling into the soil with rain. When there are too many harmful substances in the soil, which exceeds the self-purification capacity of the soil, the composition, structure and function ...
