Description

technical field [0001] The invention relates to the technical field of groundwater pollution restoration, in particular to a model device for enhanced solubilization and migration of groundwater pollutants. Background technique [0002] In recent years, with the rapid advancement of my country's modernization and rapid economic development, environmental pollution has become more and more serious. At the same time, groundwater bodies and water resource environments have also been seriously polluted. However, due to the invisibility and complexity of the groundwater environment, the complexity of movement laws, and the long migration period of groundwater, once groundwater is polluted, it is difficult to rely on the environmental system to achieve self-healing. Therefore, the research on the migration and reaction of pollutants in soil and groundwater and its influencing factors plays an important role in the management of groundwater environment, which will help to predict a...

AI Technical Summary

Problems solved by technology

However, at present, the functions of the soil column device are not complex enough, and it is not possible to do a good structural test research and practical application. There are the following problems:

[0004] 1. The complexity of simulating the actual situation is not enough

The hydrogeological characteristics that affect groundwater movement are complex and diverse. However, traditional models are often difficult to accurately simulate multi-component composite interaction systems. The addition of new materials is not well compatible, which is not conducive to the development of front-end research;

[0005] 2. The research substance cannot be recycled

The parameters in traditional devices are often fixed and cannot be changed during device design, and generally it is not possible to adjust various research areas within the model according to experimental requirements;

[0007] 4. The model has no room for improvement

The one-dimensional soil column model has many fixed modules, and generally can only be used for the same research. Therefore, when the functions and parameters of each part of the model need to be continuously adjusted during the experiment, the existing model is difficult to implement and cannot adapt to different experiments. The recycling rate of the model Low, increasing research costs
