The invention discloses a drainage pipe network pollution path monitoring and identifying method, device and electronic equipment, which relate to the field of identifying a pollution path in urban drainage management. The method comprises steps: a drainage pipe network skeleton model of a to-be-monitored area is built; according to the drainage pipe network skeleton model, possible pollution transmission paths and key nodes in the possible pollution transmission paths are identified; after distribution in the actual drainage pipe network by the key nodes, the water quantity and water qualityindex data of the actual drainage pipe network are monitored; and when the water quantity and water quality index data are monitored to be abnormal, the drainage pipe network skeleton model is used todetermine an actual pollution transmission path from the possible pollution transmission paths, the key nodes in the actual pollution transmission path are subjected to pollution forensics, and the technical problem of low intelligent level of drainage pipe network pollution identified by the existing manual monitoring technology is alleviated.
