The key factor in solving frequent chemical spill accidents is how to identify the pollution source information such as discharge location, discharge time and discharge amount or discharge rate, that caused the accident as soon as possible. Furthermore, the diffusion process of pollution accidents is simulated and predicted. Based on the proposed warning model and source identification method, an early warning and identification system for river chemical spill incidences in Jinhua River was designed and developed after collecting the geographic scope of the rivers and the national and provincial monitoring sections of Jinhua River. The system is used to simulate and predict diffusion process of pollution mass, and identify the unknown pollution source information that occurred in the Jinhua River. The early warning and identification system has been applied to the Jinhua River. The results show that the system has higher reliability, and it can provide an intuitive and scientific basis for relevant departments to respond to water pollution accidents and help them to handle pollution accidents quickly, reasonably and economically.
