摘要
本研究基于福建省某化工园区有毒有害气体预警体系的10个在线监测站点观测结果,结合园区实际情况及统计学方法,分析观测期间园区风向频率分布、各站点非甲烷总烃观测数据的相关性、各站点非甲烷总烃浓度区间频率分布情况,并提出优化初始化预警阈值的方法。结果显示,调整后的异常级预警阈值进一步适用于园区有毒有害气体预警需求。研究成果可为优化预警阈值提供基础和参考依据。
Based on the observation results of 10 online monitoring sites of toxic and harmful gas early warning system in a chemical park in Fujian Province.The paper analyzed the wind direction frequency distribution,the correlation of the observation data of non-methane hydrocarbon concentration interval,and revised the optimization method of the early warning threshold.The results show that the adjusted early warning threshold is further applicable to the early warning demand of toxic and harmful gases in the park.The research results may provide the basis and reference basis for optimizing the early warning threshold.
