Soil heavy metal content detection device and detection method

Abstract

The invention belongs to the technical field of environment detection equipment, and particularly relates to a soil heavy metal content detection device and method. The first shell assembly comprises a first shell; through the sampling mechanism, the distribution mechanism and the air drying mechanism in the first shell assembly, four groups of ground inserting steel pipes on the sampling mechanism are expanded outwards and then are distributed in four directions of the first shell assembly, so that the purpose of synchronously sampling soil layers at four different positions of a detection area is achieved; the sampled soil in the four groups of ground inserting steel pipes is sequentially sucked for air-drying treatment, conditions are provided for accurate detection of the soil, then the air-dried soil is conveyed to the second shell assembly by the air-drying mechanism for classified storage of the soil, and the effect of unified detection is achieved after batch sampling of detection personnel in different soil areas is facilitated; the soil heavy metal detection efficiency is also improved.

Description

technical field [0001] The invention belongs to the technical field of environmental detection equipment, and particularly relates to a soil heavy metal content detection device and a detection method. Background technique [0002] The life activities of soil organisms depend to a large extent on the physical and chemical properties of the soil, which mainly include soil temperature, humidity, aeration, gas composition, pH, and the quantity and composition of organic and inorganic matter. Agricultural technical measures, including tillage, cultivation, fertilization, irrigation, drainage and application of pesticides, can also affect the life activities of soil organisms. [0003] However, with the development of modern industrial and agricultural modernization and urbanization, soil pollution is becoming more and more serious, especially the pollution of heavy metals in biological soil has attracted more and more attention. Accumulate and transform into more toxic methyl c...

Problems solved by technology

[0004] Conventional soil heavy metal content detection devices are generally composed of three parts, retrieving, distributing and detecting. Among them, the conventional retrieving process is carried out by screw rods penetrating into the soil, and the retrieving efficiency is often slow. , and the soil cannot be air-dried after the reclaiming is completed, which will affect the detection accuracy of heavy metals during the detection process
