摘要： The present disclosure provides a method and system for predicting bioavailability of polycyclic aromatic hydrocarbons (PAHs) in soil. The method includes: obtaining an infrared absorption peak profile corresponding to soil to be measured; calculating an absorbance ratio at each wavelength, where the absorbance ratio is a ratio of the absorbance at a corresponding wavelength in the infrared absorption peak profile to the sum of absorbances at all wavelengths within a preset wavelength range; and inputting the absorbance ratio to a bioavailability prediction model to obtain the bioavailability of PAHs in the soil to be measured, where the bioavailability prediction model is a function constructed based on a chemical oxidation method and infrared spectroscopy to represent a relationship between bioavailability of PAHs and absorbance ratio. According to the present disclosure, the cost of measuring the bioavailability of PAHs in soil can be reduced, and the bioavailability of PAHs can be predicted rapidly. -1/4 Obtain an infrared absorption peak profile corresponding to soil to be measured Calculate an absorbance ratio at each wavelength, where the absorbance ratio is a ratio of the absorbance at a corresponding wavelength in the infrared absorption peak profile to the sum of absorbances at all wavelengths within a preset wavelength range Input the absorbance ratio to a bioavailability prediction model to obtain the bioavailability of PAHs in the soil to be measured, where the bioavailability prediction model is a function constructed based on a chemical oxidation method and infrared spectroscopy to represent a relationship between bioavailability of PAHs and absorbance ratio 05 y=-6.0609x+1.996 R2 =0915, p , 0.25 > 0.15 co 0.100 0.120 0.140 0160 0.180 0,200 0.220 Absorbance ratio

摘要： The present disclosure provides a method for determining a radius of in-situ chemical oxidation (ISCO) remediation of groundwater. The method includes the following steps: SI: setting up a well; S2: well purging and sampling; S3: collecting a groundwater sample to detect an initial pollutant concentration; S4: preparing an oxidizing agent solution; S5: placing an automatic water level monitor into the well; S6: pumping the oxidizing agent solution into injection well GO below a liquid level through a low-flow submersible pump; S7: collecting a groundwater sample to detect a pollutant concentration, an ion concentration of an oxidizing agent and a hydrochemical parameter of the groundwater; S8: analyzing changes of the pollutant concentration, the ion concentration of the oxidizing agent and the hydrochemical parameter of the groundwater. This method is used to more reasonably determine the oxidation effect of the in-situ oxidizing agent to remediate groundwater and the geometry of the influence range of single-well injection, so as to finally determine an effective radius of influence. The present disclosure provides effective technical parameters for remediation projects, and provides technical support for reducing excessive injection of the oxidizing agent. 6.19091 Water level change rate -h 3.31288 1 -0.83712 0.73636 GO G1 G2 G5 G6 Well No.

摘要： The present disclosure relates to the technical field of groundwater treatment, and in particular to a method for determining a layered characteristic and a preferential migration path of a groundwater contamination plume. The method includes the following steps: Si: performing contamination identification; S2: identifying a hydrogeological condition; S3: arranging groundwater monitor wells; S4: constructing the monitor wells in layers; S5: washing the monitor wells and collecting samples; S6: detecting the samples; S7: analyzing detection data; and S8: determining a morphology and a layered characteristic of a groundwater contamination plume through the data analysis in step S7. The present disclosure designs a three-dimensional (3D) water quality survey system to perform sampling, monitoring and 3D simulation analysis of water quality data, and achieves the purpose of depicting the layered characteristic of the groundwater contamination plume and accurately identifying the preferential migration path thereof. 17620089_1 (GHMatters) P116159.AU E 'iromendlSurve ,rof P1Qt-,' i\tr t 7
