摘要
从交通事故风险、污水排入风险以及其他风险等方面识别引江济淮工程(河南段)突发水污染事件的风险源,建立适应性的风险评价指标体系、指标等级划分标准和风险等级评价模型,综合评估7个评价河段突发水污染事件风险等级。结果表明:2个评价河段的风险等级为重大(Ⅱ级),5个评价河段的风险等级为较大(Ⅲ级)。从降低风险源危险性、提高风险控制有效性等方面提出突发水污染事件风险管控对策措施。本研究为降低引江济淮工程(河南段)突发水污染事件的发生概率和危害程度提供了支撑,对发挥工程综合效益、保障受水区供水安全、维护良好的水生态环境具有重要意义。
The Henan section of the Yangtze-to-Huaihe River Water Diversion Project is listed as one of the ten major water conservancy projects.The main functions are urban and rural water supply and improvement of water ecological environment.The water diversion volume of the project is 500 million m3 in 2030 and 634 million m3 in 2040.The Henan section is mainly composed of two open channels,four storage reservoirs,and three water pipelines.Although the risk of sudden water pollution incidents in four storage reservoirs and three water pipelines is very small,the transportation industry along the two open channels(i.e.,Qingshui River section and Luxin Canal section)is developed and there are many cross buildings,which are prone to sudden water pollution incidents.Once a water pollution incident occurs,it will have a huge impact on drinking water security,industrial water security,and the ecological environment security of the residents in the water receiving area.Therefore,it is of great significance to carry out the risk analysis of sudden water pollution incidents to give full play to the comprehensive benefits of the project,ensure the safety of water supply in the water receiving area,and maintain a good water ecological environment.The risk factors of sudden water pollution incidents in the Henan section were identified based on an investigation of the existing research results of risk analysis and control countermeasures of sudden water pollution incidents in water transfer projects,and an adaptive risk assessment index system was established.The classification criteria and risk level evaluation model comprehensively evaluated the risk levels of sudden water pollution incidents in seven evaluation sections,and risk monitoring and risk control measures for sudden water pollution incidents were proposed.The results showed that:(1)The risk sources of sudden water pollution incidents in the Henan section are road traffic accident risk,sewage discharge risk and other risks.(2)Except that the risk level of sudden water p
