Description

technical field

[0001] The invention relates to an environmental engineering and groundwater simulation experiment device, in particular to a fully automatic soil column leaching experiment device. Background technique

[0002] In recent years, with the rapid development of the economy, domestic surface water and soil have been polluted to varying degrees, which threatens the development and utilization of groundwater, affects the development of cities and the health of the people. Soil column leaching experiment is an effective method for dynamic adsorption research, which can objectively reflect the adsorption capacity and retardation capacity of pollutants in simulated regional soil or riverbed sediment to a large extent, and has an important reference for environmental risk assessment value.

[0003] At present, the principle of the soil column leaching test device used in the laboratory is basically the same. The soil column leaching test device generally consists of a...
