Problems solved by technology

The current sampling method has disadvantages such as different positions in the investigation stage and the treatment stage, soil gas, non-aqueous liquid and groundwater are not synchronized, and each target pollutant needs to be built separately in each stage, resulting in poor contrast between samples before and after, and it is difficult to accurately judge pollution. to a certain extent, the construction cost of sampling wells is high and the later maintenance is difficult

Abstract

The invention relates to a sampling well system for investigation and long-term monitoring of an organic contaminated site, and a well building method thereof. The sampling well system can be used forsampling a soil gas, a light non-aqueous phase liquid (LNAPLs) layer, a dense non-aqueous phase liquid (DNAPLs) layer and underground water of the stratum at different depths respectively in three stages of site investigation, treatment and restoration, and subsequent monitoring. For the organic contaminated site, the sampling well system has the function of sampling various kinds of contamination media in different stages by means of one monitoring well, reduces the building and maintenance costs of the sampling well, and improves the efficiency.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and relates to a well construction method for detecting and testing sampling wells for the investigation and treatment of organic polluted sites. During the investigation and treatment of organic polluted sites, soil gas, non-aqueous phase liquids (NAPLs) and groundwater can be treated. Take a sample. Background technique [0002] Typical pollutants commonly seen in organically polluted sites include: volatile alkane compounds, chlorinated hydrocarbons, benzene series, semi-volatile polycyclic aromatic hydrocarbons, petroleum hydrocarbons, nitro compounds, etc., persistent organic compounds include polychlorinated biphenyls, pesticides Wait. The national survey on soil pollution shows that the over-standard rates of H66, DDT, and PAHs are 0.5%, 1.9%, and 1.4%, respectively. Pesticide factories, chemical plants, coking plants, smelters, and gas stations After the relocation, the ...
