Abstract

The invention discloses a distribution rule analysis method for characteristic pollutants of a polluted land parcel, and relates to the technical field of environmental monitoring and pollution abatement, the analysis method comprises the following specific steps: S100, sample collection and pretreatment: collecting a soil or water sample according to a collection rule. Precise identification and concentration determination of specific pollutants of polluted land parcels are realized, and the problems of tedious operation, long time consumption and insufficient sensitivity often exist in a traditional pollutant detection method, however, absorption and scattering spectrum data of soil and water body samples can be rapidly obtained by utilizing unique properties of a terahertz spectrum, so that the detection accuracy of the pollutants in the polluted land parcels is improved. The method has the advantages that the method is simple in operation, the characteristic pollutant types in the sample can be accurately identified by comparing the characteristic pollutant types with the standard spectrum database, the concentration of each pollutant in the sample can be further calculated by utilizing the spectrum concentration interaction polynomial model, and accurate data support is provided for treatment and restoration of polluted land parcels.
