Abstract

The invention discloses a framework device applicable to soil remediation. The framework device comprises immersion mesh plates, a main beam and side beams, wherein filter holes are uniformly formed in the surfaces of the immersion mesh plates, and the main beam and the side beams are U-shaped trough plates; through-flow holes are formed in the main beam side by side along the axial direction, one end surface of the main beam is fixed on one surface of one immersion mesh plate side by side, and another immersion mesh plate is fixed on another end surface of the main beam; and two side surfaces of the main beam are blocked through the side beams. The invention further discloses a remediation method applicable to the soil remediation. The framework device is taken as a movable matrix, is filled with an attapulgite adsorption material and is applied to soil control and remediation. The remediation method is simple and rapid and applicable to industrial production; and by virtue of adsorption and exchange, the purpose of remediation of soil pollution is achieved, and the leaching concentration, mobility and toxicity degree of pollutants in soil are decreased.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and relates to a frame device suitable for soil restoration and a restoration method thereof. Background technique [0002] Soil pollution has the characteristics of poor mobility, long residence time, and irreversibility of pollutants in the soil, resulting in decreased soil fertility, reduced crop yield and quality, and polluted groundwater and surface water through runoff and leaching. [0003] Adsorption filtration is an important technology in the current deep purification of soil. At present, commonly used adsorption materials include activated carbon, activated alumina and ion exchange resins. Although they can effectively adsorb various pollutants, due to their low adsorption capacity, slow adsorption speed and poor mechanical stability, etc. , which limits its wide application. [0004] Ion exchange fiber is a new type of adsorption and separation material after ion exchange r...
