Embodiment Construction
[0032] This embodiment provides a rapid detection method for petroleum hydrocarbon organics in groundwater, the process of which is as follows figure 1 As shown, the method includes the following steps:
[0033] 1) Sample collection
[0034] Water samples were collected from the study area. According to the occurrence conditions and burial characteristics, the groundwater in this area is mainly divided into valley phreatic water and clastic rock-like pore-fissure confined water. The valley phreatic aquifer is mainly Quaternary gravel pore phreatic water, the aquifer is generally only 0.5m-2m thick, the lithology of the aquifer is mainly fine sand and gravel, and the permeability coefficient is between 0.1m / d-2.7m / d ; The sampling points are P2-P9 for valley diving, the depth is 14m-16m, and all samples are stored in light-proof containers equipped with ice packs and transported to the laboratory overnight. Collect, transport, store and analyze water samples in accordance wit...

Abstract
The invention relates to a rapid detection method of petroleum hydrocarbon organic matter in groundwater, comprising: taking a plurality of groundwater samples in a polluted area, performing three-dimensional fluorescence spectrum detection, calculating specific spectral parameters, obtaining a fitting equation, and according to the obtained fitting equation, Determine the content of petroleum hydrocarbon organic matter in the groundwater sample to be tested. The method of the present invention establishes the regular characteristics of the spectral parameters and the concentration of petroleum hydrocarbon organic matter in the petroleum hydrocarbon-contaminated groundwater, and can realize the rapid detection of the petroleum pollution of the groundwater by the portable spectral detector on site, which will help to repair efficiently Such water body pollution has positive significance for environmental protection; meanwhile, the detection method of the present invention has the characteristics of rapid detection, no need of chemical reagents, simple operation, high detection sensitivity, wide range and low cost.
Description
technical field [0001] The invention relates to a rapid detection method for petroleum hydrocarbon organic matter in groundwater, belonging to the technical field of environmental protection monitoring. Background technique [0002] Petroleum is an indispensable source of energy and a raw material for refineries and the petrochemical industry to produce fuels, synthetic polymers and petrochemicals. The possible leakage of oil and the direct discharge of oily wastewater in the process of extraction, transportation, storage and processing lead to groundwater pollution. Because petroleum contains a large number of toxic and harmful substances, such as benzene, toluene, naphthalene and anthracene, which can cause cancer, teratogenicity and mutagenesis, people have paid attention to the pollution of groundwater by petroleum. In addition, when pollutants interact with dissolved organic matter (DOM) in groundwater, the dissolution, adsorption / desorption, bioavailability, toxicity,...
