Abstract
The invention relates to a natural rainfall simulation experimental method based on an underground water dynamic simulation experimental platform. The method particularly comprises the following steps: firstly, arranging the underground water dynamic simulation experimental platform; then filling the underground water dynamic simulation experimental platform with a water-bearing stratum medium for simulating a typical hydrogeological unit; and finally carrying out a natural rainfall simulation experiment on the underground water dynamic simulation experimental platform. According to the method, different reagents can enter an aeration zone and the water-bearing stratum medium in a box type shell by multiple modes, and powdered reagents are added by virtue of a raining simulation device, so that the process that how the reagents penetrate the aeration zone from the earth surface and enter the water-bearing stratum and how the reagents are migrated and transformed in the water-bearing stratum can be observed. By adopting the method, the fidelity of simulation experiments can be improved, the cost of simulation experiments can be reduced, and a reliable experiment foundation is provided for an in-situ biological repairing technology, a permeable reactive barrier process, a soil in-situ raining repairing process and other hydrogeological research experiment projects for underground water.
Description
technical field [0001] The invention relates to an environmental hydrogeological simulation device and a simulation method, in particular to a natural rainfall simulation experiment method based on a groundwater dynamic simulation experiment platform. Background technique [0002] Groundwater resources play a pivotal role in my country's water resources and play an irreplaceable role in maintaining ecological environment security and healthy economic and social development. However, with the development of society and economy, a large amount of unreasonable discharge of domestic wastewater, industrial wastewater, agricultural pollutants, etc., as well as the disorderly development of groundwater, lead to a large number of pollutants entering the groundwater environment, causing more and more serious pollution of the vadose zone soil and groundwater , leading to the increasingly complex problem of groundwater environmental pollution. [0003] Groundwater pollution is a serio...
