Problems solved by technology

However, both the stabilization method and the soil inversion method have a common shortcoming—the pollutants are not removed from the polluted site. The heavy metal content of the site has not been reduced, which may not completely eliminate the safety concerns of the public
However, failure to remove heavy metal pollutants fro

Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. 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.

[0014] In order to have a more detailed and definite understanding of the purpose, effect and structural features of the present invention, the following preferred embodiments are now listed:

[0015] Firstly, the adsorbent of the adsorption medium in the ferromagnetic artificial nodules is selected. The selected adsorption material needs to have the characteristics of large specific surface area (that is, large adsorption capacity), especially if it has specific adsorption for heavy metals. Preferred adsorbent materials such as ze...

Abstract

The invention provides a chemical restoration method for treating heavy metal-polluted terrain soil by ferromagnetic artificial nucleuses. In a ferromagnetic artificial nucleus soil restoration method, the ferromagnetic artificial nucleuses are applied to heavy metal-polluted soil; soil above a heavy metal pollution depth is overturned by cultivation equipment to uniformly mix with the ferromagnetic artificial nucleuses; and after heavy metal can be dispersed from the soil to the artificial nucleuses by a period of time, the soil containing the artificial nucleuses is overturned by using the cultivation equipment to increase the change of the artificial nucleuses contacting with other soil. After the soil overturning procedure is repeated by multiple times, the cultivation equipment provided with magnets can be used for separating the ferromagnetic artificial nucleuses, absorbed with the heavy metal, from the polluted soil; and the content of the heavy metal of the polluted soil is reduced due to shifting-out of the ferromagnetic artificial nucleuses, so that the purpose of soil restoration is gradually achieved.

Description

technical field [0001] The invention provides a chemical rehabilitation method for on-site soil polluted by heavy metals with ferromagnetic artificial nodules. The ferromagnetic nodules in the present invention are made of ferromagnetic materials, such as ferromagnetic materials such as iron powder, magnetite, or maghemite, and adsorption heavy metal materials, such as manganese dioxide, zeolite, or vermiculite, pressurized after mixing Made into artificial tuberculosis. The ferromagnetic artificial nodules are applied to the polluted site and mixed with the contaminated soil. After the heavy metals diffuse from the contaminated soil to the ferromagnetic artificial nodules and reach saturation, the ferromagnetism that adsorbs the heavy metals is artificially combined from the soil with a magnet device. removed for the purpose of soil restoration. Background technique [0002] Soil is composed of mineral components from the weathering of rocks on the earth's land surface, a...
