Abstract: At present, the probability of environmental emergencies in China is still high, which include a high proportion of water-related incidents, bringing about a great risk to the ecological environment. By analyzing the characteristics of some typical cases of water pollution emergencies in China in recent years and the national management policies of environmental emergencies, combined with some thoughts in environmental emergency support work such as participating in emergency response and investigation for many times, the development needs and future research directions of emergency response technologies for water pollution emergencies in China were analyzed from four aspects: emergency standard formulation, emergency platform construction, emergency technology research and intelligent emergency response. These could provide a reference for establishing and improving the emergency response technology system for water pollution emergencies and improving the national environmental emergency response capacity.
