Abstract

The invention discloses a simulation test device for the release of soil heavy metals. The soil heavy metal release test device of the invention can well install the original structure of the soil for sampling to ensure the reliability of the experiment. Then, the soil test tank is sprayed with a spray assembly Spray, and then sample the soil in the soil test tank to detect heavy metals. In this way, the authenticity of the soil heavy metal release test data can be greatly improved, and it is convenient to provide a theoretical basis for the study of soil heavy metal release, ensuring the accuracy of the data and the experimental results. The convenience, the soil sampling component of the present invention can quickly and completely sample the soil, and the sampling is convenient and reliable.

Description

technical field [0001] The invention relates to a simulation test device for soil heavy metal release, and belongs to the technical field of soil heavy metal treatment simulation equipment. Background technique [0002] At present, due to human activities, the content of trace metal elements in the soil exceeds the background value, and the content caused by excessive deposition is too high, resulting in soil heavy metal pollution, which causes the deterioration of the ecological environment quality. Heavy metals cannot be degraded by microorganisms and are long-term and potential pollutants in the environment. Due to the adsorption of soil colloids and particulate matter, heavy metals exist in the soil for a long time, and the concentration is mostly in a vertically decreasing distribution. , hydroxide ions, corrosive substances, etc.) to form complexes or chelates, resulting in greater solubility and mobility of heavy metals in the soil, soil heavy metals can be bio-accumu...
