Embodiment Construction
[0028] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0029] Such as figure 1 Shown, a kind of soil composite heavy metal pollution control and resource utilization method of the present invention comprises the steps:
[0030] 1) Adding adsorption materials: adding magnetic adsorption materials to the soil polluted by heavy metals, and mixing the magnetic adsorption materials with the soil, so that the heavy metals in the soil can migrate to the magnetic adsorption materials, so as to realize the separation of heavy metals from the soil;
[0031] 2) Magnetic separation: use multi-stage magnetic separation to separate and collect saturated magnetic adsorption materials from the soil, so as to achieve the restoration and treatment of soil contaminated by heavy metals;
[0032] 3) Desorption of the adsorption material: put the saturated magnetic adsorption material into the desorption stirring equipmen...
