三维荧光光谱-熵权法在水污染溯源中的应用研究

Application of three Dimensional Fluorescence Spectroscopy-Entropy Weight Method in Water Pollution Traceability

为了提高污水溯源效率,同时降低溯源成本。采用三维荧光光谱-熵权法对污水进行溯源,使用含有不同成分的水样,检验其溯源效果。结果表明,在不同水样等体积混合后,混合后的水样与混合前各水样三维荧光光谱相似度接近的前提下,该批水样按不同体积混合后,体积占比越大,其与混合样的相似度越高,体积越小反之。该方法在a、b两市成功溯源出违法排污企业,同时其还可以对雨污水管网混接错接等行为提供排查指导方向。相比于传统方法大大提高了水污染事件等的溯源排查效率。

In order to improve the efficiency of sewage traceability and reduce the traceability cost.The Three-dimensional fluorescence spectroscopy-Entropy weight method was used to trace the source of sewage,and the water samples containing different components were used to test the traceability effect.The results show that under the premise that the similarity of the 3D fluorescence spectra of the mixed water samples is close to that of the water samples before mixing,the larger the volume proportion of the water samples after mixing by different volumes,the higher the similarity between the water samples and the mixed samples,and the smaller the volume,the vice versa.This method successfully traced the source of illegal sewage enterprises in cities a and b.At the same time,it can also provide guidance for the investigation of mixed connection and wrong connection of rainwater and sewage pipe network.Compared with the traditional methods,it greatly improves the efficiency of tracing and investigating water pollution incidents.
