Problems solved by technology

[0004] However, the contaminated soil remediation systems in the prior art all add the microorganisms required for degradation at one time, which either leads to excessive input of microorganisms or insufficient input of microorganisms. The root cause is that there is no supply and feedback in this system. The process of remediation of contaminated soil is not complete and the effect is not good

Abstract

The invention provides a system and a method for repairing polluted soil by utilizing a microbiological degradation technology, which are characterized in that a soil sample is extracted, the isotope abundance ratio of pollution elements in different periods is measured by utilizing a secondary ion mass spectrometry, and the concentration of residual pollution elements is calculated by utilizing a stable isotope analysis method; therefore, the input quantity of the microorganism input system is controlled. The change condition of pollutants in the soil is mastered in real time, a feedback mechanism is formed for the soil remediation condition and the microorganism input quantity, and balance of microorganisms in the soil is guaranteed.

Description

technical field [0001] The invention relates to the technical field of contaminated soil remediation, in particular to a system and method for remediating contaminated soil by utilizing microbial degradation technology. Background technique [0002] Bioremediation refers to the conversion of toxic environmental pollution compounds into harmless substances through microbial digestion. Bioremediation has been successfully used to treat above-ground treatment systems, above-ground slurry bioreactors, slurry pits, above-ground soil piles, composted materials and contaminated soil in situ. [0003] Bioremediation is accelerated by adding nutrients, pH modifiers and oxygen (if aerobic microorganisms are used) to the soil and / or water of interest. By adjusting these parameters, indigenous microorganisms will multiply and become more active, leading to faster waste degradation. If the native microorganism does not have the genes required to produce the enzymes necessary to degrade...
