Microbial soil remediation device and method

Abstract

The invention discloses a microbial soil remediation device, comprising a remediation box, wherein the upper end of the remediation box is fixedly connected with a transverse plate through two supporting rods, the side wall of the transverse plate is rotatably connected with a plurality of rotating wheels which are in transmission connection through a belt, and the side walls of the rotating wheels are coaxially and fixedly connected with rotating shafts. The invention further provides an application method of the microbial soil remediation device. The application method comprises the following steps that: S1, the device is placed in open space which can be irradiated by sunlight and is good in ventilation; S2, the filling amount of a thermal-expansion and cold-contraction medium is adjusted; S3, a transparent glass plate is taken out; S4, contaminated soil is placed; S5, a microbial flora is added; S6, nutrient substances are fed and oxygen is supplied; and S7, the transparent glass plate is covered. By arranging a sliding plug which can be automatically adjusted according to sunlight temperature, the rotating angle of a double-sided mirror is further adjusted, so sunlight rays atdifferent moments can be reflected by the double-sided mirror and then vertically irradiate the interior of the repairing box; and thus, repairing process is more thorough.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a microbial soil remediation device and method. Background technique [0002] Soil microbial remediation technology is a remediation technology that uses indigenous microorganisms or artificially domesticated microorganisms with specific functions to reduce the activity of harmful pollutants in the soil or degrade them into harmless substances through their own metabolism under suitable environmental conditions. [0003] In terms of remediation sites, soil microbial remediation technologies are mainly divided into two categories, namely in-situ microbial remediation and ex-situ microbial remediation, in which ex-situ microbial remediation needs to move the contaminated soil to the corresponding reactor and then add microbial flora Degradation, because the repaired biological flora needs sunlight to degrade, and the reactor can only cover the entire reactor evenly when th...

[0003] In terms of remediation sites, soil microbial remediation technologies are mainly divided into two categories, namely, in-situ microbial remediation and ex-situ microbial remediation. Among them, ex-situ microbial remediation needs to move the contaminated soil to the corresponding reactor and then add microbial flora for biological remediation. Degradation, because the repaired biological flora needs sunlight to degrade, and the reactor can only cover the entire reactor evenly when the sun is shining vertically at noon. In the morning and evening, when the light is tilted, it will be partly blocked by the side of the r
