Abstract

The invention discloses a laboratory soil leaching device which comprises an electric stirrer, a soil storage tank, a filtrate barrel and a dosing barrel, the electric stirrer is mounted on a lifting platform and can extend into the soil storage tank, the soil storage tank is arranged in the filtrate barrel through a storage rack, the dosing barrel is connected with a spray header through a metering pump, the spray header is mounted above the soil storage tank, a bottom plate of the soil storage tank is provided with a filter screen, and the spray header is connected with an adjusting valve. According to the invention, the deficiency of a small soil leaching device in a laboratory is solved, and the detection data of the soil after leaching and the leacheate after use can be obtained at the same time; the soil dosage and the leacheate dosage are flexibly controlled, and the spraying speed of the leacheate is controlled; the experiment efficiency can be improved, and composite experiment data can be collected in the same experiment; usage is simple and effective, and application range is wide.

Description

technical field [0001] The invention belongs to the technical field of contaminated soil leaching test equipment, and relates to a device for laboratory soil leaching. Background technique [0002] With the rapid development of industry and agriculture and the urbanization of rural areas, the problem of soil inorganic and organic pollution is becoming more and more serious, and the area of ​​soil pollution is also increasing year by year. Inorganic pollutants mainly include heavy metals such as cadmium, mercury, lead, chromium, zinc and non-metals such as arsenic; organic pollutants mainly include benzopyrene and organic pesticides. Soil is an important part of the ecological environment and a repository for biogeochemical cycles of substances. The problem of soil pollution in our country has become more serious, and the restoration and treatment of polluted soil is a problem that cannot be ignored. [0003] Soil leaching refers to the process of injecting or infiltrating ...
