| Abstract: |
| The frequent occurrence of sudden water pollution accidents seriously threatens the aquatic environment, threatens aquatic organisms, suffers social and economic losses, and causes bad social impacts. It is an important way to reduce the harm of the accident by carrying out risk identification and evaluation before the accident and adopting emergency prevention and control measures. This research used the literature survey method to summarize the research status and development trend of risk assessment and emergency countermeasures based on the identification of sudden water pollution risk, and adopted the expert opinion method to put forward the quantitative classification basis of environmental risk receptors the analogy method was used to classify the sudden water pollution risk assessment method, and studied the emergency countermeasures according to the environmental risk characteristics.Summing up the sudden water pollution risk sources included fixed pollution sources and mobile pollution sources, it was concluded that sudden water pollution risk assessment included three methods:Qualitative evaluation method, semi-quantitative evaluation method and quantitative evaluation method. And an early warning index system for emergency plans was constructed, and the emergency plans were sorted out according to the response time flow. In the future, sudden water pollution risk assessment and emergency countermeasures will further expand the identification of risk sources and build a comprehensive evaluation technical specification system. |
