Abstract

The invention discloses a pollution source analysis method and device and a storage medium, and belongs to the technical field of water environment protection and monitoring. The method comprises the following steps: detecting a water sample by adopting a three-dimensional fluorescence spectrum detection method and an electrochemical spectrum detection method to obtain multi-dimensional spectrum data; carrying out dimension reduction processing on the multidimensional spectral data by utilizing an entropy weight method, and respectively calculating distribution weights of atlas matrixes; distributing weights based on the atlas matrix, and constructing a two-dimensional weight matrix; and calculating the similarity between the two-dimensional weight matrix and a weight matrix in a pre-constructed database by adopting an Euclidean distance judgment analysis method, and determining the pollution source. According to the method, the active components in the water quality are enhanced by electrochemical disturbance, more information is provided for water pollution source analysis to excavate hidden water quality spectral information, and the identification degree of water quality detection traceability is increased; and meanwhile, pollution source tracing analysis is performed by using an entropy weight method-Euclidean distance, so that the accuracy of pollution source identification and analysis is improved.

Description

technical field [0001] The invention relates to the technical field of water environmental protection and monitoring, and in particular to a pollution source analysis method, device and storage medium. Background technique [0002] The existence of sneak discharge of sewage and accidental pollution discharge has caused a very serious impact on the quality of the water environment. It has brought a huge impact and has a serious impact on the water quality of the river. How to quickly find the source of sewage is the key and difficult problem of current water pollution early warning and management research. [0003] At present, the commonly used sewage traceability methods are: on-site sampling traceability method and numerical simulation method. The on-site sampling traceability method includes isotope tracing method, water pattern identification method, and spectroscopic method. The traceability of this method is highly reliable, but it needs to be used. It consumes a lot ...
