Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil dioxin pretreatment grinding device. Background Art

[0002] Dioxins generally refer to a group of polychlorinated planar aromatic compounds with similar components and physical and chemical properties. They belong to the class of chlorinated oxygen-containing tricyclic aromatic compounds, including 75 polychlorinated dibenzo-p-dioxins and 135 polychlorinated dibenzofurans. These substances are neither artificially produced nor used, but are by-products of combustion and various industrial production. The main sources of dioxins in the environment are evaporation caused by the use of chlorophenols for wood preservation and prevention of schistosomiasis, emissions from incineration industries, the use of defoliants, the preparation of pesticides, the bleaching of paper, and emissions from automobile exhaust. Dioxins accumulate in soil, atmosphere, and water. When detecting dioxins in soil, the soil sample needs to be ground and screened first.
