Contaminated site sampling device and seepage pollution detection system

Abstract

Belonging to the technical field of environmental pollution detection, the invention relates to a contaminated site sampling device and a seepage pollution detection system. The sampling device comprises: a sampling body, a liquid collection tank, a vacuum pumping component, a pressurization component and a sampling bottle. The sampling body is a porous ceramic structure, and the liquid collection tank is an internally enclosed cavity structure, is arranged above the sampling body and is communicated with the sampling body through an infusion tube. The vacuum pumping component is communicated with the liquid collection tank through a pipeline. The pressurization component is communicated with the liquid collection tank through a pipeline. The sampling bottle is communicated with the liquid collection tank through a sampling tube. The detection system comprises a plurality of sampling devices. The sampling bodies and liquid collection tanks in the plurality of sampling devices are fixed at a plurality of sampling points set at the contaminated site, and the plurality of sampling points are located at different depths. The contaminated site sampling device and the seepage pollution detection system provided by the invention can perform long-term continuous sampling and monitoring on contaminated soil, and have the advantages of comprehensive monitoring information, convenient installation and sampling, real-time and efficient monitoring, and accurate seepage detection position.

Description

Technical field [0001] The invention relates to the technical field of environmental pollution detection, in particular to a sampling device for contaminated sites and a leakage pollution detection system. Background technique [0002] According to the National Soil Pollution Survey Bulletin issued by the Ministry of Environmental Protection, the overall state of the soil environment in the country is not optimistic, with heavy soil pollution in some areas, poor soil environmental quality of cultivated land, and serious environmental problems in abandoned industrial and mining land. Man-made activities such as industry, mining, agriculture, and high soil environmental background values ​​are the main reasons for soil pollution or exceeding standards. The country’s total soil over-standard rate was 16.1%, of which the proportions of slightly, lightly, moderately and severely polluted points were 11.2%, 2.3%, 1.5% and 1.1%. The type of pollution is mainly inorganic type, followed ...
