Linkage pre-treatment remediation device for contaminated soil

Abstract

The invention discloses a linkage pre-treatment remediation device for contaminated soil. The linkage pre-treatment remediation device for contaminated soil comprises a remediation box. A guide pipe is connected to the top of the remediation box, and the other end of the guide pipe is connected to the bottom of the side face of a pre-treatment box. A vertical shaft is mounted in the middle of thepre-treatment box. A crushing knife is mounted on in the pre-treatment box and is located on the vertical shaft. A screen is mounted under the crushing knife. A rotary cylinder is arranged in the middle of the remediation box. A plurality of stirring mechanisms are mounted on the portion, located in the remediation box, of the rotary cylinder. A second bevel gear is mounted at the left end of therotary cylinder. A first bevel gear engaged with the second bevel gear is mounted at the lower end of the vertical shaft. The right end of the rotary cylinder is connected with a liquor pipe. A pressure pump is mounted on the liquor pipe. The other end of the liquor pipe is connected to the bottom of the side face of a liquor box. The linkage pre-treatment remediation device for contaminated soilis reasonable in structural design; soil can be pretreated, and intermittent feeding and discharging for processing can be achieved, the liquor adding and mixing effect is good, and the soil remediation quality is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a linkage pretreatment and remediation device for contaminated soil. Background technique [0002] After chemicals pollute the soil, the chemical materials will quickly penetrate into the soil and kill the microorganisms in the soil, thereby changing the composition of the soil and changing the ecology of the surface. The polluted area may be barren for decades or even hundreds of years. Moreover, chemical materials also pollute oceans, rivers and lakes, and groundwater. [0003] Many studies have shown that some chemical materials have carcinogenic, teratogenic and mutagenic effects on mammals and humans after entering the body of animals. Severe pollution of the soil will lead to the accumulation of certain components of chemical materials in the grain, affecting the quality of the grain, and endangering human health through the food chain. [0004] In the existing s...

AI Technical Summary

Problems solved by technology

However, the existing chemical soil remediation device does not have a pretreatment structure, the structure of feeding and discharging materials is single, and it is impossible to feed and discharge materials intermittently, and the addition of chemicals is more traditional, and the mixing effect is not good, which affects the quality of soil remediation
