Problems solved by technology

[0002] At present, there are many limitations in the research on the release of heavy metals in soil. The experimental dimension of the research is not wide enough to simulate the extreme temperature, acid rain acidity, rainfall, light intensity and other factors of a place at the same time, and the scale of the experiment is also limited. Small, can't dock well with the actual situation

Embodiment 1

[0016] A kind of method that contains heavy metal soil strengthening simulation test described in this embodiment, such as figure 1 As shown, the specific steps are as follows:

[0017] (1) Collect different batches of test soil samples and fully mix them into 3 samples. Naturally air-dry the collected test samples at room temperature, remove debris such as gravel, wood chips, plastics, weeds and shells, grind them with an agate mortar, dry them in an oven at 105°C, pass them through a 100-mesh nylon sieve, and store them in numbers In a self-sealing polyvinyl chloride bag for heavy metal analysis;

Abstract

The invention discloses a heavy metal containing soil intensified simulation test method. According to the heavy metal containing soil intensified simulation test method, heavy metal containing soil (experimental soil) obtained via solidification and stabilization treatment is taken as a study object of heavy metal release kinetics; firstly, analysis on the properties of the experimental soil is carried out, then the experimental soil is introduced into a treatment tank for experiments at different composite dimensions, wherein the temperature is controlled to be 25 to 35 DEG C, the simulatedrainfall is controlled to be the single point maximum rainfall, the pH value of simulated rain is controlled to be 4 to 8, the simulated illumination intensity is controlled to be 1 to 3 times of local mean annual illumination intensity, and local seawater is adopted for seawater corrosion. The process of the heavy metal containing soil intensified simulation test method is simple; operation is convenient; drug using amount is low; the heavy metal release rules of the heavy metal containing soil obtained via solidification and stabilization treatment at different composite dimensions can b obtained; the volume of the experimental soil in the heavy metal containing soil intensified simulation test method is 0.785m<3>, the results are close to practical situations, and strong data support isprovided for subsequent simulation tests.

Description

technical field [0001] The invention relates to a method for intensifying simulation tests on soil containing heavy metals, and belongs to the technical field of hazardous waste treatment. Background technique [0002] At present, there are many limitations in the research on the release of heavy metals in soil. The experimental dimension of the research is not wide enough to simulate the extreme temperature, acid rain acidity, rainfall, light intensity and other factors of a place at the same time, and the scale of the experiment is also limited. It is small and cannot be well docked with the actual situation. Therefore, it will become a research hotspot in this field to study a test method for the release of heavy metals in soil under large-scale multi-dimensional conditions. Contents of the invention [0003] Aiming at the problems and deficiencies in the above-mentioned prior art, the present invention proposes a method for intensifying simulation tests on heavy metal...
