Abstract

The invention discloses a sample preparation device for petroleum hydrocarbon pollution detection in soil; the sample preparation device comprises a sleeve, an outer pipe and an inner pipe, wherein the outer pipe is located in the sleeve, the inner pipe is located in the outer pipe, and the top end of the inner pipe is fixedly connected with a fixing plate. In the sample preparation device for detecting the petroleum hydrocarbon pollution in the soil, the two ends of the cross rod penetrate through the outer pipe and extend into the outer pipe. After the sampling is finished, the sample can be immediately crushed and screened, so that in the process of returning to a laboratory, the sample can be prepared and packaged by a packaging bottle, more time is saved, and the sampling device is convenient to use. The device can be used for two purposes; wherein the top end of the inner pipe is fixedly connected with the fixing plate, the outer pipe is convenient to disassemble and assemble, and the inner pipe is located at the bottom of the interior of the outer pipe during sampling and located on the upper portion of the interior of the outer pipe during crushing and screening, so that enough space is provided for screening.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a sample preparation device for detection of petroleum hydrocarbon pollution in soil. Background technique [0002] Petroleum hydrocarbons are complex mixtures, among which benzene series and polycyclic aromatic hydrocarbons are mostly organic substances with high toxicity and suspected "three-cause" effects. Petroleum hydrocarbons can migrate in the medium, so they can flow from the source of leakage to soil and groundwater. and air migration, causing the expansion of the polluted area and affecting the surrounding environment of the pollution source. Exceeding the concentration of petroleum hydrocarbons in the soil will destroy the soil ecosystem, reduce soil fertility, and cause plant growth to slow down. Petroleum hydrocarbon pollutants entering the soil will also follow The surface flows into the surface water body, causing surface water pollution; petroleum hydrocarb...
