背景技术Background technique
近年来我国重大环境污染事件频繁发生，对生态环境、人民健康及社会安全产生严重影响。从我国当前重大环境污染事件发生的实际状况出发，结合国际环境科学技术发展前沿，研究开发适合我国国情的重大环境污染事件监控技术系统，是提升我国环境保护技术水平，推进环境友好型社会发展的迫切要求。In recent years, major environmental pollution incidents have occurred frequently in my country, which have seriously affected the ecological environment, people's health and social security. Starting from the actual situation of major environmental pollution incidents in my country, combined with the frontiers of international environmental science and technology development, research and development of a major environmental pollution incident monitoring technology system suitable for my country's national conditions is to improve the level of environmental protection technology in my country and promote the development of an environmentally friendly society. Urgent request.
其中，“风险源监控”主要针对历次重大环境污染事件中的典型污染物，选择满足监控指标的在线监测设备，集成在线监测、数据处理与传输技术，构建重点风险源动态监控平台，开展不同规模的监测监控示范。Among them, "risk source monitoring" mainly focuses on typical pollutants in previous major environmental pollution incidents, selects online monitoring equipment that meets the monitoring indicators, integrates online monitoring, data processing and transmission technologies, and builds a dynamic monitoring platform for key risk sources. Demonstration of monitoring and monitoring.
随着人类生产和使用化学品的种类、数量不断增加，大量有机污染物、有毒有害污染物进入环境，容易引发环境污染事故，其潜在的健康和生态风险已经成为人们关注的焦点。挥发性有机物(volatile organic compounds，VOCs)被世界卫生组织定义为沸点在50～260℃、室温下饱和蒸气压＞133.322Pa的易挥发性化合物。其主要成分为脂肪烃、芳香烃、卤代烃、氧烃、氮烃、硫烃和一些醛、酮、醚、酯类化合物，部分已被列为致癌物(如苯和氯乙烯)。As the types and quantities of chemicals produced and used by humans continue to increase, a large number of organic pollutants and toxic and harmful pollutants enter the environment, which may easily cause environmental pollution accidents, and their potential health and ecological risks have become the focus of attention. Volatile organic compounds (volatile organic compounds, VOCs) are defined by the World Health Organization as volatile compounds with a boiling point of 50-260°C and a saturated vapor pressure of >133.322Pa at room temperature. Its main components are aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons, nitrogen hydrocarbons, sulfur hydrocarbons, and some aldehydes, ketones, ethers, and esters, some of which have been listed as carcinogens (such as benzene and vinyl chloride).
一氧化碳、硫化氢、氨气、氯气等有毒气体，甲烷、氯甲烷、丁烷、氢气等可燃气体广泛应用于石油、化工、冶金、电力等行业。VOCs是石油、化工、制药、印刷、建材、喷涂等企业经常使用和排放的物质。特别要强调的是，许多VOCs有易燃易爆特性，这些爆炸品、泄露品进入环境，将对环境造成很大的污染，对人类生命财产造成重大损失。相关企业在这些物质的储存、生产和运输环节若存在安全管理隐患，极易酿成重大环境污染事故。如世界有名的环境污染事件马斯河谷事件，马斯河谷工业区炼焦、炼钢、电力、玻璃、炼锌、硫酸、化肥等工厂排放的大量烟雾弥漫在河谷上空无法扩散，有害气体积存量接近危害健康的极限。一个星期内就有60多人死亡，是同期正常死亡人数的十多倍。印度博帕尔毒气泄漏事件，该厂的一个储料罐进水，罐中的化学原料发生剧烈的化学反应，储料罐爆炸，41吨异氰酸甲酯泄漏到居民区，酿成迄今世界最大的化学污染事件。Carbon monoxide, hydrogen sulfide, ammonia, chlorine and other toxic gases, methane, methyl chloride, butane, hydrogen and other combustible gases are widely used in petroleum, chemical, metallurgy, electric power and other industries. VOCs are substances frequently used and emitted by enterprises such as petroleum, chemical, pharmaceutical, printing, building materials, and spraying. In particular, it should be emphasized that many VOCs are flammable and explosive. These explosives and leaks will cause great pollution to the environment and cause great losses to human life and property when they enter the environment. If relevant enterprises have hidden dangers in safety management in the storage, production and transportation of these substances, it is very easy to cause major environmental pollution accidents. For example, the Maas Valley incident, a world-famous environmental pollution incident, a large amount of smoke emitted by factories such as coking, steelmaking, electricity, glass, zinc smelting, sulfuric acid, and chemical fertilizers in the Maas Valley Industrial Zone filled the valley and could not be diffused, and the volume of harmful gas was close to Health hazard limit. More than 60 people died within a week, more than ten times the normal death toll during the same period. In the Bhopal poisonous gas leakage incident in India, water entered a storage tank of the plant, and the chemical raw materials in the tank had a violent chemical reaction. The storage tank exploded, and 41 tons of methyl isocyanate leaked into residential areas, causing the world Largest chemical pollution incident.
