Embodiment
[0034] Such as figure 1 , figure 2 As shown, this embodiment specifically provides a microcosm experimental device 100 for simulating the remediation of soil pollution to test the remediation performance of microbial degradation of soil pollution. The microcosm experimental device 100 includes a parallel sampling device 3, a temperature control box 16, a parameter monitoring system, a soil column experimental device 8 and a drainage structure.
[0035] The temperature control box 16 is a conventional temperature-controllable box-type structure, made of stainless steel, and its temperature control range is -30°C-40°C. The bottom thickness of the temperature control box 16 is 50 mm, and the side wall thickness is 10 mm. The bottom of the temperature control box 16 is provided with three rows of evenly arranged grooves 10; the grooves 10 are cylindrical structures with an inner diameter of 100 mm and a height of 30 mm. The bottom of the groove 10 is provided with a drainage s...

Abstract
The invention relates to the technical field of soil microcosm simulation, in particular to a microcosm experiment device for simulating remediation of soil pollution. The microcosm experiment devicecomprises a parallel sample adding device, a temperature control box, a parameter monitoring system, a soil column experiment device and a drainage structure. The parallel sample adding device is arranged at the upper end of the temperature control box and is externally connected with a sample adding pump and a sample adding pipe. The parallel sample adding device is used for synchronously addingexperimental materials into the soil column experiment device. The soil column experiment device is located at the bottom of the temperature control box, and an experiment soil sample and sampling holes with different heights are arranged in the middle. The drainage structure and the parameter monitoring system are used for discharging device waste liquid and monitoring parameters. The microcosm experiment device can flexibly control the environment temperature of a microcosm system, sampling tests can be carried out at any time, the continuous process of soil remediation can be known throughmultiple continuous sampling tests, the remediation process is basically not influenced, and the microcosm experiment device has good practicability.
Description
technical field [0001] The present application relates to the technical field of soil microcosm simulation, in particular to a microcosm experimental device for simulating and remediating soil pollution. Background technique [0002] Microcosm is a simulated experimental method that extrapolates the results of a single experiment to complex natural ecosystems and can conduct in-depth analysis of ecosystems through laboratories. With the advancement of science and technology, microcosm experiments have been applied in various disciplines, especially environmental ecology. For example, Dai Wei et al. analyzed the predation effect of myxobacteria on prey bacteria in the microenvironment by constructing an artificial microcosm system; Cui Song et al. found that the change of soil vertical stratification temperature was correlated with the migration and diffusion flux coefficient of α-HCH. significant positive correlation etc. The microcosm experiment has the advantages of real...
