Problems solved by technology

[0004] Existing soil heavy metal detection methods usually pretreat the soil, during which the soil is dried and pulverized. If the pieces are crushed together, the crushed weeds and stones are difficult to separate from the soil, which will affect the results of soil testing

Abstract

The invention relates to the technical field of soil detection, in particular to a soil heavy metal pollution detection method, which comprises the following steps: 1, soil sample collection: collecting a soil sample near a place where heavy metal pollutants need to be detected through a container; step 2, soil pretreatment: extruding and crushing the collected soil sample through a pretreatment device, removing weeds and stones in the soil after extruding and crushing, and then drying, crushing and sieving the soil from which the weeds and the stones are removed through the pretreatment device; 3, preparing a liquid to be detected. According to the device, through the arrangement of the extruding and sieving device, collected soil is extruded and crushed, so that blocked soil fragments are reduced, meanwhile, the soil fragments are sieved through a filter screen through rotation, the soil fragments fall down, weeds and stones are left, and therefore the weeds and the stones in the soil are removed; and the influence of internal components of weeds and stones on a soil detection result is favorably avoided.

Description

technical field [0001] The invention relates to the field of soil detection, in particular to a method for detecting soil heavy metal pollution. Background technique [0002] With the development of society, the pollution of heavy metals in my country's soil has gradually become serious in recent years. For example, abnormalities such as cadmium, mercury, lead, and arsenic are common in some areas in the middle and lower reaches of the Yangtze River. Abnormal mercury and lead are common in cities and their surrounding areas. Abnormal radioactivity, enrichment of harmful elements in lakes, and serious soil acidification. In order to understand the situation of soil pollution, it is necessary to detect heavy metals in the soil. [0003] The prior art discloses some invention patents on soil detection. The Chinese patent application number is 202110336743.6, which discloses a soil heavy metal pollution detection device, which includes a device main body. A power box is fixedly i...
