The invention provides a traceability method for drain outlets at the tail end of a municipal drainage pipe network and drain outlets in an underground culvert, which comprises the basic steps of discharge outlet attribute judgment, water flow type judgment, distribution mode selection and traceability monitoring, and establishes a traceability standardization system and flow of the discharge outlets in the drainage pipe network and the underground culvert suitable for different scenes. On-site investigation personnel can conveniently and intuitively select a suitable tracing method according to different conditions, meanwhile, by establishing a discharge port attribute judgment process, the defect that an intermittent cutoff discharge port cannot be judged by other methods is overcome, and through a judgment method for distinguishing industrial sewage and domestic sewage, a physical observation method is adopted to primarily judge the water flow type firstly, and then the water flow type is calculated. And a
