Description
Technical Field
The utility model belongs to the technical field of the environment is administered, a well construction system of detection chemical examination sampling well of organic pollution place investigation, improvement is related to, in organic pollution place investigation and treatment period, can take a sample soil gas, non-aqueous phase liquid (NAPLs) and groundwater.
Background
Typical contaminants common to organically contaminated sites include: volatile alkane compounds, chlorinated hydrocarbons, benzene series, semi-volatile polycyclic aromatic hydrocarbons, petroleum hydrocarbons, nitro compounds and the like, and persistent organic compounds comprise polychlorinated biphenyl, pesticides and the like. The national soil pollution condition survey shows that the point standard exceeding rate of the hexachloro cyclohexane, the dichlorodiphenyl trichloroethane and the polycyclic aromatic hydrocarbon 3 organic pollutants is respectively 0.5 percent, 1.9 percent and 1.4 percent, and the soil and the underground water of the field after the relocation of pesticide plants, chemical plants, coking plants, smelting plants and gas stations can be subjected to subsequent development after the soil and the underground water are usually repaired to reach the standard.
The leakage and diffusion of pollutants in different organic pollution sites are greatly influenced by factors such as topography, geology, soil hydrology, pollutant characteristics and the like, and parameters such as underground water depth, soil layer permeability coefficient, liquid density of pollutants and the like directly determine occurrence states and distribution concentrations of the pollutants in the soil and underground water of the sites. A strong-permeability field with low melting point of organic pollutants and mainly sandy soil is easy to form soil gas with environmental and health risks; when the field soil has strong permeability, the aeration zone is thin and the underground water level is shallow, organic matters with specific gravity smaller than that of water float on the surface of the underground water after the organic pollutants leak, so that light non-aqueous phase liquids (LNAPLs) are formed, such as carbon hydrocarbon compounds, benzene series and petroleum hydrocarbon, which are common in fields of pesticides, chemical engineering, petrochemical engineering and the like. Organic matters with specific gravity larger than that of water settle on the bottom layer of underground water to form heavy non-aqueous phase liquids (DNAs PLs), common chlorine-containing organic solvents such as trichloroethylene, tetrachloroethylene and carbon tetrachloride, coal tar and the like, and are often used in electronic factories, electronic part cleaning, chemical factories, chemical product manufacturing, paint blending in printing and dyeing factories, pesticide manufacturing factories, commercial dry cleaning and waste solvents used for household decoration, wherein the chlorine-containing organic solvents are used in large quantities; meanwhile, for a site with a deeper first aquifer of the underground water, such as a beach geological site and the like, the distribution difference of pollutants in the underground water at different burial depths is also larger.
The method for developing and utilizing the repaired polluted site directly determines the exposure way of the environmental risk generated by the environmental sensitive receptors and the site residual pollutants in the future, for example, volatile organic matters can form polluted exposure through the invasion of indoor steam generated by soil gas, and organic matters which are easily dissolved in water can form the exposure way through drinking water and the like. As the organic pollution sites in China are numerous, the difference of the pollution production industry is large, the hydrogeological conditions are different, the repair and treatment modes are diversified, and the soil gas, the non-aqueous phase liquid (NAPLs including the upper layer and the lower layer, DNAs and LNAPLs) and the underground water at different depths in the sites need to be sampled and detected irregularly at different stages of investigation and treatment. The existing sampling method has the defects that soil gas, non-aqueous phase liquid and underground water are not synchronous in different positions in an investigation stage and a treatment stage, and wells need to be built for target pollutants in each stage, so that the problems that the front and back contrastiveness of a sample is poor, the pollution degree is difficult to judge accurately, the construction cost of a sampling well is high, the later maintenance is difficult and the like are caused.
