The invention relates to a water supply pipe network pollution source tracking and positioning method based on user complaint information. The method comprises the following steps of S1, generating apollution matrix by using position information complained by a user; S2, judging the similarity among the candidate nodes and dividing the similarity; S3, increasing random complaint lag time and constructing a user complaint sample; And S4, carrying out training verification test on the convolutional neural network by using the complaint sample of the user, and applying the convolutional neural network to actual pollution source tracking and positioning. Compared with the prior art, according to the real-time user complaint information after the pollution accident happens, the user complaintmode recognition is adopted for pollution source positioning, the good pollution source recognition capability is achieved for water source pollution and non-water-source pollution, and certain robustness is achieved for uncertainty of the user complaint lag time. In the cities with incomplete pipe network water quality on-line monitoring equipment, the system has the advantages that the pollutionsource position can be quickly positioned, and the emergency response capability of cities to pipe network water quality accidents is enhanced.
