Abstract：In this study, the pollution of direct and leakage in Shiwuli River was analyzed by combining anionic surfactant sodium dodecyl benzene sulfonate (SDBS) and dissolved organic matter (DOM) traceability methods, and the correlation and difference of each index were studied by Pearson correlation analysis method. The results showed that the content of SDBS in untreated domestic sewage was high (522~668μg/L), which was easily affected by industrial washing wastewater when characterizing the pollution situation. DOM is characterized by high percentage of CHOS compounds (83%~84%), protein + lipid components (80%~81%), high hydrogen-carbon ratio (H/C=1.6) and low-carbon nominal oxidation state (NOSC=-1) in untreated domestic sewage. Combining the advantages of SDBS and DOM traceability can effectively eliminate interference factors and make the characterization of river domestic sewage pollution more reliable. This study can provide new ideas and technical support for the analysis and traceability of the direct and leakage of domestic sewage pollution in rivers.
